machine and storage bin:
• Drain lines must have a 1.5-inch drop per 5 feet of run
(2.5 cm per meter), and must not create traps.
• The floor drain must be large enough to accommodate
drainage from all drains.
• Install a tee at the ice machine drain outlet and install
an 18.0” (46 cm) vent above the drain line.
• Insulate drain lines to prevent condensation.
• Vent the bin and ice machine drain to the atmosphere.
Do not vent the condenser drain on water-cooled
models.
COOLING TOWER APPLICATIONS
Water Cooled Models Only
A water-cooling tower installation does not require
modification of the ice machine. The water regulator valve
for the condenser continues to control the refrigeration
discharge pressure.
It is necessary to know the amount of heat rejected, and
the pressure drop through the condenser and water valves
(inlet to outlet) when using a cooling tower on an ice
machine.
• Water entering the condenser must not exceed 90°F
(32.2°C).
• Water flow through the condenser must not exceed
5 gallons (19 liters) per minute.
• Allow for a pressure drop of 7 psig (0.48 bar) between
the condenser water inlet and the outlet of the ice
machine.
• Water exiting the condenser must not exceed 110°F
(43.3°C).

36 - Modular Part Number 000018624 Rev 00 4/26
Calculated Line Set Distance
The maximum calculated distance is 150' (45.7 m).
Line set rises, drops, horizontal runs (or combinations
of these) in excess of the stated maximums will exceed
compressor start-up and design limits. This will cause poor
oil return to the compressor.
Make the following calculations to make sure the line set
layout is within specifications.
1. Insert the measured rise into the formula below.
Multiply by 1.7 to get the calculated rise.
(Example: A condenser located 10 feet above the ice
machine has a calculated rise of 17 feet.)
2. Insert the measured drop into the formula below.
Multiply by 6.6 to get the calculated drop.
(Example. A condenser located 10 feet below the ice
machine has a calculated drop of 66 feet.)
3. Insert the measured horizontal distance into the
formula below. No calculation is necessary.
4. Add together the calculated rise, calculated drop,
and horizontal distance to get the total calculated
distance. If this total exceeds 150' (45.7 m), move
the condenser to a new location and perform the
calculations again.

De-scaling and Sanitizing
GENERAL
Sanitizing for Exterior, Remedial, and Detailed procedures
can be performed independently and more frequently
than de-scaling when needed.
De-scale and sanitize the ice machine every six months
for efficient operation. If the ice machine requires more
frequent de-scaling and sanitizing, consult a qualified
service company to test the water quality and recommend
appropriate water treatment. An extremely dirty ice
machine must be taken apart for de-scaling and sanitizing.
Manitowoc Ice Machine De-scaler and Sanitizer are
the only products approved for use in Manitowoc ice
machines.
Using non Manitowoc de-scalers, sanitizers, cleaners or
solutions may result in bodily harm and/or cause damage
to the ice machine that is not covered under the warranty.
The ice machine must be taken apart for de-scaling and
sanitizing.
Maintenance procedures are not covered by the warranty.
,
Caution
Use only Manitowoc Ice Machine De-scaler (part
number 9405463) and Sanitizer (part number
9405653). Do not mix De-scaler and Sanitizer solutions
together. It is a violation of Federal law to use these
solutions in a manner inconsistent with their labeling.
Read and understand all labels printed on bottles
before use.
Maintenance
40 - Modular Part Number 000018624 Rev 00 4/26
ICE MACHINE INSPECTION
Check all water fittings and lines for leaks. Also, confirm
refrigeration tubing is not rubbing or vibrating against
other tubing, panels, etc.
Do not put anything (boxes, etc.) in front of the ice
machine. There must be adequate airflow through and
around the ice machine to maximize ice production and
ensure long component life.
EXTERIOR CLEANING
Clean the area around the ice machine as often as
necessary to maintain cleanliness and efficient operation.
Wipe surfaces with a damp cloth rinsed in water to remove
dust and dirt from the outside of the ice machine. If a greasy
residue persists, use a damp cloth rinsed in a mild dish soap
and water solution. Wipe dry with a clean, soft cloth.
Products containing abrasives will damage the coating and
scratch the panels.
• Never use steel wool or abrasive pads for cleaning.
• Never use chlorinated, citrus based or abrasive
cleaners on exterior panels and plastic trim pieces.
REMEDIAL DESCALING
• This procedure de-scales all components in the water
flow path, and is used between the bi-yearly detailed
de-scaling and sanitizing procedure.
DETAILED DESCALING/SANITIZING
This procedure must be performed a minimum of once
every six months.
• The ice machine and bin must be disassembled de-
scaled and sanitized.
• All ice produced during the de-scaling and sanitizing
procedures must be discarded.
Part Number 000018624 Rev 00 4/26 Modular - 41
DETAILED DESCALING AND SANITIZING PROCEDURE
Ice machine de-scaler is used to remove lime scale and

Remedial De-scaling Procedure
This procedure de-scales all components in the water flow
path, and is used to de-scale the ice machine between the
bi-yearly detailed de-scaling and sanitizing procedure.
Ice machine de-scaler is used to remove lime scale and
mineral deposits. Ice machine sanitizer disinfects and
removes algae and slime.
Step 1 Ice must not be on the evaporator during the
clean/sanitize cycle. Follow one of the methods below:
• Move the toggle switch to the OFF position at
the end of a harvest cycle after ice falls from the
evaporator.
• Move the toggle switch to the OFF position and
allow the ice to melt.
,
Caution
Never use anything to force ice from the evaporator.
Damage may result.
n
Warning
Wear rubber gloves and safety goggles (and/or face
shield) when handling Ice Machine De-scaler or
Sanitizer.
Part Number 000018624 Rev 00 4/26 Modular - 49
Step 2 Open the front door and move the toggle
switch to the CLEAN position. Wait until the water trough
refills (approximately 1 minute) and then add the proper
amount of Ice Machine Descaler to the water trough.

Cleaning the Air Filter & AirCondenser
n
Warning
Disconnect electric power to the ice machine head
section and the remote condensing unit at the electric
service switches before cleaning the condenser.
The washable filter on self-contained ice machines is
designed to catch dust, dirt, lint and grease. Clean the filter
once a month with mild soap and water.
A dirty condenser restricts airflow, resulting in excessively
high operating temperatures. This reduces ice production
and shortens component life.
n
Warning
The condenser fins are sharp. Use care when cleaning
them.
• Clean the condenser at least every six months.
• Shine a flashlight through the condenser to check for
dirt between the fins.
• Blow compressed air or rinse with water from the
inside out (opposite direction of airflow).
• If dirt still remains, call a service agent to clean the
condenser.

Ice Making Sequence of Operation
NOTE: The toggle switch must be in the ICE position and
the water curtain must be closed before the ice machine
will start.
Water Purge Cycle
The ice machine purges any remaining water from the
water trough down the drain and the refrigeration
compressor starts and the refrigeration compressor starts.
Freeze Cycle
Prechill - The refrigeration system chills the evaporator
before water flow over the evaporator starts. The water
inlet valve energizes during the pre-chill and remains on
until the ice thickness float switch is satisfied.
Freeze - Water flowing across the evaporator freezes
and builds ice on the evaporator. After a sheet of ice has
formed, the Harvest float switch signals the control board
to start a harvest cycle.
Dump Cycle
Upon initial start-up or start-up after an auto shut-off,
water flows through the water dump valve and down the
drain. If the water trough fails to drain after the water
dump valve has energized/
de-energized, a clean light will flash.
Harvest Cycle
Any remaining water is purged down the drain as
refrigerant gas warms the evaporator. When the
evaporator warms, the sheet of cubes slides off the
evaporator and into the storage bin. If all cubes fall clear
of the water curtain, the ice machine starts another freeze
cycle.
Operation
54 - Modular Part Number 000018624 Rev 00 4/26
Full Bin Cycle
If the water curtain is held open by ice cubes, the ice
machine shuts off and starts a 3-minute delay period.
When the water curtain closes, the ice machine starts a
new cycle at the water purge, provided the 3-minute delay
period has expired.
CONTROL BOARD TIMERS
• The ice machine is locked into the freeze cycle for
6 minutes before a harvest cycle can be initiated.
• The freeze time lock in feature is bypassed on the
initial cycle (manual start or after a full bin/safety limit
condition).
• If the harvest float switch is in the down position for
10 continuous seconds during the start of an initial
freeze cycle, a harvest sequence is initiated. If the
harvest float is in the down position in subsequent
cycles a safety limit 3 cycle is initiated.
• The maximum freeze time is 35 minutes (60 minutes
prior to software revision 3.2) at which time the
control board automatically initiates a harvest
sequence.
• The maximum harvest time is 3.5 minutes (software
revision 3.2 and later, 7 minute max harvest, with
water assist after 3.5 minutes. SL#2 will shut down
after 100 cycles). The control board automatically
initiates a freeze sequence when these times are
exceeded.
• The ice machine will continue to fill with water for up
to six minutes, or until the high water float opens for
5 continuous seconds. The control board will energize
the water inlet valve one more time 3 minutes into the
freeze cycle.
Part Number 000018624 Rev 00 4/26 Modular - 55

Operational Checks
ICE THICKNESS CHECK
After a harvest cycle, inspect the ice cubes in the ice
storage bin. The ice thickness float switch is factory-set to
maintain the ice bridge thickness at 1/8” (3 mm).
NOTE: Make sure the water curtain is in place when
performing this check. It prevents water from splashing out
of the water trough.
1. Inspect the bridge connecting the cubes. It should be
about 1/8” (3 mm) thick.
2. If adjustment is necessary make the following
adjustment as you face the machine.
NOTE: The float can be adjusted with a 3/4” wrench while
the water trough is in place.
• Turn the ice thickness float switch to the right to
increase bridge thickness
• Turn the ice thickness float switch to the left to
decrease bridge thickness.
• Test run two cycles to verify bridge thickness.

Diagnosing an Ice Machine that Will Not Run
n
Warning
High (line) voltage is applied to the control board at
all times. Removing the control board fuse or pressing
the power button will not remove the power supplied
to the control board.
1. Verify primary voltage is supplied to ice machine and
the fuse/circuit breaker is closed.
2. Verify control board fuse is okay.
NOTE: If any control board lights are on, the fuse is okay.
3. Verify the bin switch functions properly. A defective
bin switch can falsely indicate a full bin of ice.
4. Verify toggle switch functions properly. A defective
toggle switch may keep the ice machine in the OFF
mode. Refer to toggle switch diagnostics when Steps
1 – 3 test good.
5. Be sure Steps 1 – 4 were followed thoroughly.
Intermittent problems are not usually related to the
control board. Replace control board if toggle switch
operation is correct.

How to Use the Freeze Cycle Refrigeration System
Operational Analysis Table
GENERAL
These tables must be used with charts, checklists and
other references to eliminate refrigeration components
not listed on the tables and external items and problems
which can cause good refrigeration components to appear
defective.
The tables list five different defects that may affect the ice
machine’s operation.
NOTE: A low-on-charge ice machine and a starving
expansion valve have very similar characteristics and are
listed under the same column.
NOTE: Before starting, see “Before Beginning Service” for
a few questions to ask when talking to the ice machine
owner.
PROCEDURE
Step 1 Complete the “Operation Analysis” column.
Read down the left “Operational Analysis” column.
Perform all procedures and check all information listed.
Each item in this column has supporting reference material
to help analyze each step.
While analyzing each item separately, you may find an
“external problem” causing a good refrigerant component
to appear bad. Correct problems as they are found. If
the operational problem is found, it is not necessary to
complete the remaining procedures.
Part Number 000018624 Rev 00 4/26 Modular - 75
Step 2 Enter Checkmarks ().
Each time the actual findings of an item in the
“Operational Analysis” column matches the published
findings on the table, enter a Checkmark.
Example: Freeze cycle suction pressure is determined to be
low. Enter a Checkmark in the “low” column.
Step 3 Add the Checkmarks listed under each of
the four columns. Note the column number
with the highest total and proceed to “Final
Analysis.”
NOTE: If two columns have matching high numbers,
a procedure was not performed properly, supporting
material was not analyzed correctly or the problem
component is not covered by the analysis table.
Before Beginning Service
Ice machines may experience operational problems
only during certain times of the day or night. A machine
may function properly while it is being serviced, but
malfunctions later. Information provided by the user can
help the technician start in the right direction, and may be
a determining factor in the final diagnosis.
Ask these questions before beginning service:
• When does the ice machine malfunction? (night, day,
all the time, only during the Freeze cycle, etc.)
• When do you notice low ice production? (one day a
week, every day, on weekends, etc.)

Ice Machine Does Not Cycle Into Harvest when the
Harvest Float Is Down/Closed
NOTE: The ice machine will make a thick or double slab
when a new freeze cycle is started with ice already present
on the evaporator.
Two of the most common scenarios are:
• Power is cycled off/on with ice on the evaporator.
• The water curtain/bin switch is opened/closed in the
harvest cycle before the ice releases.
Remove all ice from the evaporator before starting
diagnostic procedures.
Freeze Time Lock-In Feature
The ice machine control system incorporates a freeze
time lock-in feature. This prevents the ice machine from
short cycling in and out of harvest. The control board locks
the ice machine in the freeze cycle for six minutes. After
six minutes a harvest cycle can be initiated. To allow the
service technician to initiate a harvest cycle without delay,
this feature is not used on the first cycle after moving the
toggle switch to OFF and back to ON.

Ice Production Check
The amount of ice a machine produces directly relates to
the operating water and air temperatures. This means an
ice machine with a 70°F (21°C) ambient temperature and
50°F (10°C) water produces more ice than the same ice
machine with 90°F (32°C) ambient and 70°F (21°C) water.
1. Determine the ice machine operating conditions:
Air temp entering condenser:____°
Air temp around ice machine:____°
Water temp entering sump trough:____°
2. Refer to the appropriate 24-Hour Ice Production
Chart. Use the operating conditions determined in
Step 1 to find published 24-Hour Ice Production:_____
• Times are in minutes.
Example: 1 min. 15 sec. converts to 1.25 min.
(15 seconds ÷ 60 seconds = .25 minutes)
• Weights are in pounds.
Example: 2 lb. 6 oz. converts to 2.375 lb.
(6 oz. ÷ 16 oz. = .375 lb.)
3. Perform an ice production check using the formula

closely. If they match closely, determine if:
• Another larger ice machine is required.
• Relocating the existing equipment to lower the
load conditions is required.

A water-related problem often causes the same symptoms
as a refrigeration system component malfunction.
Example: A water dump valve leaking during the freeze
cycle, a system low on charge, and a starving TXV have
similar symptoms.
Water system problems must be identified and eliminated
prior to replacing refrigeration components.

Ice Formation Pattern
Evaporator ice formation pattern analysis is helpful in ice
machine diagnostics.
Analyzing the ice formation pattern alone cannot diagnose
an ice machine malfunction. However, when this analysis
is used along with the Refrigeration System Operational
Analysis Table, it can help diagnose an ice machine
malfunction.
OUTLET
INLET
Example of Evaporator Tubing Routing
Normal Ice Formation
Ice forms across the entire evaporator surface.
At the beginning of the Freeze cycle, it may appear that
more ice is forming on the inlet of the evaporator than at
the outlet. At the end of the Freeze cycle, ice formation
at the outlet will be close to, or just a bit thinner than,
ice formation at the inlet. The dimples in the cubes at the
outlet of the evaporator may be more pronounced than
those at the inlet. This is normal.
If ice forms uniformly across the evaporator surface, but
does not do so in the proper amount of time, this is still
considered a normal ice fill pattern.
88 - Modular Part Number 000018624 Rev 00 4/26
Extremely Thin at Evaporator Outlet
There is no ice, or a considerable lack of ice formation on
the outlet of the evaporator.
Examples: No ice at all at the outlet of the evaporator, but
ice forms at the inlet half of the evaporator. Or, the ice at
the outlet of the evaporator reaches the correct thickness,
but the outlet of the evaporator already has 1/2" to 1"
(12 to 25 mm) of ice formation.
Extremely Thin at Evaporator Inlet
There is no ice, or a considerable lack of ice formation at
the inlet of the evaporator. Examples: The ice at the outlet
of the evaporator reaches the correct thickness, but there
is no ice formation at all at the inlet of the evaporator.
No Ice Formation
The ice machine operates for an extended period, but
there is no ice formation at all on the evaporator.
Evaporator Tubing Routing
Routing of the tubing on the back of the evaporator
determines the ice fill pattern failure mode.
One Evaporator, One TXV Models
The evaporator outlet tubing does not exit directly at the
top of the evaporator, but exits several inches below the
top of the evaporator. Extremely Thin at the Evaporator
Outlet will first be visible several inches below the top of
the evaporator. Extremely Thin at Evaporator Inlet will first
be visible at the bottom of the evaporator.
Part Number 000018624 Rev 00 4/26 Modular - 89
One Evaporator, Two TXV 48" Models
Tubing routing for one evaporator with two TXV’s is
different. The evaporator has two inlets and outlets. Fill
pattern varies depending on which circuit is affected,
Extremely Thin at the Evaporator Outlet
Will first be visible 1/3 of the way down the evaporator.
Only one side of the evaporator may be affected
depending on failure. A TXV failure will usually show on
only one side, while low on refrigerant can affect one or
both sides depending on the amount of refrigerant loss
and ambient temperature.
Extremely Thin at the Evaporator Inlet
Will show at the bottom of the evaporator. Depending on
the failure either the entire bottom of the evaporator or
one side of the bottom of the evaporator may be affected.

Analyzing Suction Pressure
The suction pressure gradually drops throughout the
freeze cycle. The actual suction pressure (and drop rate)
changes as the air and water temperature entering the
ice machine changes. These variables also determine the
freeze cycle times.
To analyze and identify the proper suction pressure drop
throughout the freeze cycle, compare the published
suction pressure to the published freeze cycle time.
NOTE: Analyze discharge pressure before analyzing suction
pressure. High or low discharge pressure may be causing
high or low suction pressure.
Part Number 000018624 Rev 00 4/26 Modular - 91
Procedure
Step
1. Determine the ice machine operating conditions.
Example:
Air temp. entering condenser: 90°F/32.2°C
Air temp. around ice machine: 80°F/26.7°C
Water temp. entering water fill valve: 70°F/21.1°C
2A. Refer to “Cycle Time” and “Operating Pressure” charts for ice
machine model being checked. Using operating conditions from
Step 1, determine published freeze cycle time and published
freeze cycle suction pressure.
Example:
Published freeze cycle time: 14.8 - 15.9 minutes
Published freeze cycle suction pressure: 65 - 26 psig
2B. Compare the published freeze cycle time and published
freeze cycle suction pressure. Develop a chart.
Example:
Published Freeze Cycle Time (minutes)
1 2 4 7 10 12 14
| | | | | | |
65 55 47 39 34 30 26
Published Freeze Cycle Suction Pressure (psig)
In the example, the proper suction pressure should be
approximately 39 psig at 7 minutes; 30 psig at 12 minutes; etc.
3. Perform an actual suction pressure check at the beginning,
middle and end of the freeze cycle. Note the times at which the
readings are taken.
Example:
Manifold gauges were connected to the example ice machine
and suction pressure readings taken as follows: ________ PSIG
Beginning of freeze cycle: 79 (at 1 min.)
Middle of freeze cycle: 48 (at 7 min.)
End of freeze cycle: 40 (at 14 min.)
4. Compare the actual freeze cycle suction pressure (Step 3)
to the published freeze cycle time and pressure comparison
(Step 2B). Determine if the suction pressure is high, low or
acceptable.
Example:
In this example, the suction pressure is considered high
throughout the freeze cycle. It should have been:
Approximately 65 psig (at 1 minute) – not 79
Approximately 39 psig (at 7 minutes) – not 48
Approximately 26 psig (at 14 minutes) – not 40

Comparing Evaporator Inlet and Outlet Temperatures
The temperatures of the suction lines entering and leaving
the evaporator alone cannot diagnose an ice machine.
However, comparing these temperatures during the freeze
cycle, along with the Refrigeration System Operational
Analysis Table, can help diagnose an ice machine
malfunction.
The actual temperatures entering and leaving the
evaporator vary by model, and change throughout the
freeze cycle. This makes documenting the “normal”
inlet and outlet temperature readings difficult. The key
to the diagnosis lies in the difference between the two
temperatures five minutes into the freeze cycle. These
temperatures must be within 7°F (4°C) of each other.
Use this procedure to document freeze cycle inlet and
outlet temperatures.
1. Use a quality temperature meter, capable of taking
temperature readings on curved copper lines.
2. Attach the temperature meter sensing device to the
copper lines entering and leaving the evaporator.
Important
Do not simply insert the sensing device under the
insulation. It must be attached to and reading the
actual temperature of the copper line.
3. Wait five minutes into the freeze cycle.
4. Record the temperatures below and determine the
difference between them.
___________ ___________ ___________
Inlet Temperature Difference must be within
7°F (4°C) at 5 minutes into

The discharge pressure is normal when the actual
pressure falls within the published pressure range for the

discharge pressure to be higher at the beginning of the
freeze cycle (when load is greatest), then drop throughout
the freeze cycle.

Harvest Valve
General
The harvest valve is an electrically operated valve that
opens when energized, and closes when de-energized.
Normal Operation
The valve is de-energized (closed) during the freeze cycle
and energized (open) during the harvest cycle. The valve is
positioned between the compressor discharge line and the
evaporator and performs two functions:
1. Prevents refrigerant from entering the evaporator
during the freeze cycle.
The harvest valve is not used during the freeze cycle.
The harvest valve is de-energized (closed) preventing
refrigerant flow from the discharge line into the
evaporator.
2. Allows refrigerant vapor to enter the evaporator in
the harvest cycle.
During the harvest cycle, the harvest valve is
energized (open) allowing refrigerant gas from the
discharge line of the compressor to flow into the
evaporator. The heat is absorbed by the evaporator
and allows release of the ice slab.
Exact pressures vary according to ambient temperature
and ice machine model. Harvest pressures can be found
in the Cycle Time/24 Hour Ice Production/ Refrigerant
Pressure Charts in this book.
98 - Modular Part Number 000018624 Rev 00 4/26
HARVEST VALVE ANALYSIS
The valve can fail in two positions:
• Valve will not open in the harvest cycle.
• Valve remains open during the freeze cycle.
Valve will not open in the harvest cycle
Although the circuit board has initiated a harvest cycle,
the evaporator temperature remains unchanged from the
freeze cycle.
Valve remains open in the freeze cycle:
Symptoms of a harvest valve remaining partially open
during the freeze cycle can be similar to symptoms of an
expansion valve or compressor problem. Symptoms are
dependent on the amount of leakage in the freeze cycle.
A small amount of leakage will cause increased freeze
times and an ice fill pattern that is “Thin at the Outlet”, but
fills in at the end of the cycle.
As the amount of leakage increases, the length of the
freeze cycle increases and the amount of ice at the outlet
of the evaporator decreases.
Refer to the Parts Manual for proper valve application. If
replacement is necessary, use only “original” replacement
parts.
Part Number 000018624 Rev 00 4/26 Modular - 99
Use the following procedure and table to help determine
if a harvest valve is remaining partially open during the
freeze cycle.
1. Wait five minutes into the freeze cycle.
2. Feel the inlet of the harvest valve(s).
Important
Feeling the harvest valve outlet or across the harvest
valve itself will not work for this comparison.
The harvest valve outlet is on the suction side (cool
refrigerant). It may be cool enough to touch even if the
valve is leaking.
3. Feel the compressor discharge line.
n
Warning
The inlet of the harvest valve and the compressor
discharge line could be hot enough to burn your hand.
Just touch them momentarily.
4. Compare the temperature of the inlet of the harvest
valves to the temperature of the compressor
discharge line.
100 - Modular Part Number 000018624 Rev 00 4/26
Findings Comments
The inlet of the harvest valve
is cool enough to touch and
the compressor discharge line
is hot.
Cool & Hot
This is normal as the discharge
line should always be too hot
to touch and the harvest valve
inlet, although too hot to touch
during harvest, should be
cool enough to touch after 5
minutes into the freeze cycle.
The inlet of the harvest
valve is hot and approaches
the temperature of a hot
compressor discharge line.
Hot & Hot
This is an indication something
is wrong, as the harvest
valve inlet did not cool down
during the freeze cycle. If
the compressor dome is also
entirely hot, the problem is
not a harvest valve leaking, but
rather something causing the
compressor (and the entire ice
machine) to get hot.
Both the inlet of the harvest
valve and the compressor
discharge line are cool enough
to touch.
Cool & Cool
This is an indication something
is wrong, causing the
compressor discharge line to
be cool to the touch. This is
not caused by a harvest valve
leaking.
5. Record your findings on the table.
Part Number 000018624 Rev 00 4/26 Modular - 101
Discharge Line Temperature Analysis
GENERAL
Knowing if the discharge line temperature is increasing,
decreasing or remaining constant can be an important
diagnostic tool. Maximum compressor discharge line
temperature on a normally operating ice machine steadily
increases throughout the freeze cycle. Comparing the
temperatures over several cycles will result in a consistent
maximum discharge line temperature.
Ambient air temperatures affect the maximum discharge
line temperature.
Higher ambient air temperatures at the condenser = higher
discharge line temperatures at the compressor.
Lower ambient air temperatures at the condenser = lower
discharge line temperatures at the compressor.
Regardless of ambient temperature, the freeze cycle
discharge line temperature will be higher than 150°F (66°C)
on a normally operating ice machine.
PROCEDURE
Connect a temperature probe on the compressor discharge
line within 6" (15 cm) of the compressor. Observe the
discharge line temperature for the last three minutes of
the freeze cycle and record the maximum discharge line
temperature.
102 - Modular Part Number 000018624 Rev 00 4/26
Discharge Line Temperature Above 150°F (66°C) at End of
Freeze Cycle:
Ice machines that are operating normally will have
consistent maximum discharge line temperatures above
150°F (66°C).
Verify the expansion valve sensing bulb is positioned and
secured correctly.
Discharge Line Temperature Below 150°F (66°C) at End of
Freeze Cycle
Ice machines that have a flooding expansion valve will have
a maximum discharge line temperature that decreases
each cycle.
Verify the expansion valve sensing bulb is 100% insulated
and sealed airtight. Condenser air contacting an incorrectly
insulated sensing bulb will cause overfeeding of the
expansion valve.

Final Analysis - Self-contained Air, Water & Remote
Condenser Models
The column with the highest number of check marks
identifies the refrigeration problem.
COLUMN 1 HARVEST VALVE LEAKING
Replace the valve as required.
COLUMN 2 LOW CHARGE/TXV STARVING
Normally, a starving expansion valve only affects the freeze
cycle pressures, not the harvest cycle pressures. A low
refrigerant charge normally affects both pressures. Verify
the ice machine is not low on charge before replacing an
expansion valve.
1. Add refrigerant charge to verify a low charge (air and
water self-contained only). Do not add more than
30% of nameplate refrigerant charge. If the problem is
corrected, the ice machine is low on charge.
NOTE: Do not add charge to remote models. The
symptoms of a remote low on charge will result in a service
long freeze in cool ambient temperatures. Check the liquid
line temperature at the ice machine. The liquid line will be
hot with a normal or below normal head pressure in freeze
when the ice machine is low on refrigerant.
2. Find the refrigerant leak. The ice machine must
operate with the nameplate charge. If the leak cannot
be found, proper refrigerant procedures must still be
followed. Change the liquid line drier. Then, evacuate
and weigh in the proper charge.
3. If the problem is not corrected by adding charge, the
expansion valve is faulty.
104 - Modular Part Number 000018624 Rev 00 4/26
COLUMN 3 TXV FLOODING OR REFRIGERANT
OVERCHARGE
A loose or improperly mounted expansion valve bulb
causes the expansion valve to flood. Check bulb mounting,
insulation, etc, before changing the valve. Verify refrigerant
amount is correct by weighing recovered refrigerant before
replacing a TXV.
COLUMN 4 COMPRESSOR
Replace the compressor. To receive warranty credit, the
compressor ports must be properly sealed by crimping and

Main Fuse
Function
The control board fuse stops ice machine operation if
electrical components fail causing high amp draw.
Specifications
• The main fuse is 250 Volt, 3.15 amp.
n
Warning
High (line) voltage is applied to the control board at
all times. Removing the control board fuse or cycling
the toggle switch Off/On will not remove the power
supplied to the control board.
Check Procedure
1. If the curtain light is on with the water curtain closed,
the fuse is good.
n
Warning
Disconnect electrical power to the entire ice machine
before proceeding.
2. Remove the fuse. Check the resistance across the fuse
with an ohmmeter.

Component Check Procedures
112 - Modular Part Number 000018624 Rev 00 4/26
Bin Switch
Function
Bin switch operation is controlled by the movement of the
water curtain. The bin switch has two main functions:
1. Terminating the harvest cycle and returning the ice
machine to the freeze cycle.
This occurs when the bin switch is opened and closed
again within 30 seconds of opening during the harvest
cycle.
2. Automatic ice machine shut-off.
If the storage bin is full at the end of a harvest cycle,
the sheet of cubes fails to clear the water curtain and
holds it down. After the water curtain is held down
for 30 seconds, the ice machine shuts off.
The ice machine remains off until enough ice is
removed from the storage bin to allow the sheet of
cubes to drop clear of the water curtain. As the water
curtain swings back to the operating position, the bin
switch closes and the ice machine restarts.
Important
The water curtain must be installed (bin switch closed)
to start ice making.
Check Procedure
1. Cycle the toggle switch OFF.
2. Watch the curtain light on the control board.
3. Move the water curtain upward, toward the
evaporator. The bin switch must close. The curtain
light “on” indicates the bin switch has closed properly.
4. Move the water curtain away from the evaporator.
The bin switch must open. The curtain light “off”
indicates the bin switch has opened properly.
Part Number 000018624 Rev 00 4/26 Modular - 113
Ohm Test
1. Disconnect the bin switch wires from the control
board.
2. Connect an ohmmeter to the disconnected bin switch.
3. Cycle the bin switch open and closed numerous times
by opening and closing the water curtain.
NOTE: To prevent misdiagnosis:
• Always use the water curtain magnet to cycle the
switch (a larger or smaller magnet will affect switch
operation).
• Watch for consistent readings when the bin switch is
cycled open and closed (bin switch failure could be
erratic).
114 - Modular Part Number 000018624 Rev 00 4/26
Float Switch
Function
Open and close to indicate to the control board the level of
water in the water trough.
Specifications
Normally closed, float operated magnetic reed switch.
The float switch contacts are closed in the down position.
When water raises the float to the up position the magnet
in the float opens the contacts.
Check Procedure
The ice machine uses two float switches.
Ice Thickness Float - Indicates the water level has been
reached.
Harvest Float - Indicates a harvest cycle needs to be
initiated.
Initial testing can be performed by viewing the control
board light(s) while raising and lowering the float. The
corresponding control board light must turn on and off
when the float is raised and lowered.
Harvest Float Switch:
A. The light must be on in the up position.
B. The light must be off in the down position.
Ice Thickness Float Switch:
A. The light must be off in the down position.
B. The light must be on in the up position.
Part Number 000018624 Rev 00 4/26 Modular - 115
If the control board light does not respond to the float,
proceed with Step 1 below.
1. Disconnect power to the ice machine and pull the
float switch and connector through the ice machine
base and disconnect.
2. Attach an ohm meter lead to each float switch wire.
3. Place the float in the down position - The float switch
must be closed.
4. Place the float in the up position - The float switch
must be open.
5. If the float tests good, ohm the interconnecting wires
to the control board and inspect connectors.
NOTE: Make adjustments with the ice machine in the off
position. Making adjustments during the freeze cycle may
produce an initial sheet of ice that is thicker than future
cycles.

Compressor Electrical Diagnostics
The compressor does not start or will trip repeatedly on
overload.
Check Resistance (Ohm) Values
NOTE: Compressor windings can have very low ohm
values. Use a properly calibrated meter.
Perform the resistance test after the compressor cools. The
compressor dome should be cool enough to touch (below
120°F/49°C) to ensure that the overload is closed and the
resistance readings will be accurate.
Single Phase Compressors
1. Disconnect power and remove the wires from the
compressor terminals.
2. The resistance values between C and S and between
C and R, when added together should equal the
resistance value between S and R.
3. If the overload is open, there will be a resistance
reading between S and R, and open readings between
C and S and between C and R. Allow the compressor
to cool, then check the readings again.
Check Motor Windings to Ground
Check continuity between all three terminals and the
compressor shell or copper refrigeration line. Scrape metal
surface to get good contact. If continuity is present, the
compressor windings are grounded and the compressor
should be replaced.
To determine if the compressor is seized, check the amp
draw while the compressor is trying to start.
Part Number 000018624 Rev 00 4/26 Modular - 117
Compressor Drawing Locked Rotor
The two likely causes of this are:
• Defective starting component
• Mechanically seized compressor
To determine which you have:
1. Install high and low side gauge.
2. Try to start the compressor.
3. Watch the pressures closely.
• If the pressures do not move, the compressor is
seized. Replace the compressor.
• If the pressures move, the compressor is
turning slowly and is not seized. Check the start
components.
Compressor Drawing High Amps
The continuous amperage draw on start-up should not be
near the maximum fuse size indicated on the serial tag.
The wiring must be correctly sized to minimize voltage
drop at compressor start-up. The voltage when the
compressor is trying to start must be within ±10% of the
nameplate voltage.
118 - Modular Part Number 000018624 Rev 00 4/26
PTCR
The PTCR allows current to flow through the start winding
at compressor startup. Current flow heats the ceramic
discs in the PTCR. The electrical resistance increases with
temperature and stops all except a trickle of current flow
through the start winding. The small flow of current keeps
the PTCR hot (260°F/127°C) and the start winding out of
the circuit.
The PTCR must be cooled before attempting to start the
compressor, otherwise the PTCR will heat up too quickly
and stop current flow through the start winding before the
compressor motor reaches full speed.
n
Warning
Disconnect electrical power to the entire ice machine
at the building electrical disconnect box before
proceeding.
NOTE: If a PTCR is dropped internal damage can occur
to the ceramic PTCR discs. The ceramic disc can chip and
cause arcing which leads to PTCR failure. Since there is no
way to open the PTCR in order to determine if the ceramic
disc is chipped or not, it must be discarded when dropped.
Part Number 000018624 Rev 00 4/26 Modular - 119
PTCR Operation Check
1. Visually inspect the PTCR. Check for signs of physical
damage.
NOTE: The PTCR case temperature may reach 210°F
(100°C) while the compressor is running. This is normal. Do
not change a PTCR just because it is hot.
2. Wait at least 10 minutes for the PTCR to cool to room
temperature.
3. Remove the PTCR from the ice machine.
4. Measure the resistance of the PTCR as shown. The
resistance reading must be between:

Refrigeration Components
HEAD PRESSURE CONTROL VALVE
Koolaire remote systems require head pressure control
valves with special settings. Replace defective head
pressure control valves only with “original” Koolaire
replacement parts.
Refrigerant Charge Verification
The correct amount of refrigerant (name plate charge) is
required to operate correctly at all ambient conditions.
An ice machine with an overcharge or undercharge of
refrigerant may function properly at higher ambient
temperatures and fails at lower ambient temperatures.
Symptoms of incorrect refrigerant amount are:
• Works during the day and malfunctions at night, and/
or fails whenever the outdoor temperature drops.
• A Safety limit is stored in control board memory.
Refrigerant loss and ambient temperature are directly
related to each other. As the ambient temperature drops,
more refrigerant is stored in the condenser.
When the refrigerant charge and ambient temperature
create an undercharge of refrigerant in the freeze cycle,
the receiver dip tube will lose it’s liquid seal. Without liquid
refrigerant to the TXV, the ice machine fails to make a full
sheet of ice in 60 minutes and a safety limit #1 results.
NOTE: When a head pressure control valve is being
replaced or refrigerant charge is suspected, verify the
refrigerant charge is correct by recovering the refrigerant,
weighing and comparing to the nameplate amount.
Refer to Refrigerant Recovery/Evacuation for recovery
procedures.
Part Number 000018624 Rev 00 4/26 Modular - 123
FREEZE CYCLE OPERATION ALL MODELS
The head pressure control valve is non adjustable.
At ambient temperatures of approximately 70°F (21°C)
or above, refrigerant flows through the valve from the
condenser to the receiver inlet. At temperatures below
this (or at higher temperatures if it is raining), the head
pressure control dome’s nitrogen charge closes the
condenser port and opens the bypass port from the
compressor discharge line.
In this modulating mode, the valve maintains minimum
head pressure by building up liquid in the condenser and
bypassing discharge gas directly to the receiver.
HARVEST CYCLE OPERATION
Remote Condenser Models
The head pressure control cycles into full bypass due to the
pressure drop when the harvest valve opens. Refrigerant
flows from the compressor to the evaporator through the
harvest valve and the head pressure valve is out of the
circuit.
Diagnostics
FREEZE CYCLE REMOTE CONDENSER
1. Determine if the coil is clean.
2. Determine the air temperature entering the
condenser.
3. Determine if the head pressure is high or low in
relationship to the outside temperature. (Refer to
the proper “Cycle Times/24-Hour Ice Production/
Refrigerant Pressure Charts”).
4. Determine the temperature of the liquid line entering
the receiver by feeling it. This line is normally warm;
“body temperature.”
5. Using the information gathered, refer to the chart.
124 - Modular Part Number 000018624 Rev 00 4/26
NOTE: A head pressure control valve that will not
bypass, will function properly with condenser air
temperatures of approximately 70°F (21°C) or above.
When the temperature drops below 70°F (21°C), the head
pressure control valve fails to bypass and the ice machine
malfunctions. Lower ambient conditions can be simulated
by rinsing the condenser with cool water during the freeze
cycle.

HARVEST PRESSURE REGULATING VALVE HPR
SYSTEM REMOTE CONDENSER ONLY
GENERAL
The harvest pressure regulating (HPR) system includes:
• Harvest pressure regulating solenoid valve (HPR
solenoid). This is an electrically operated valve which
opens when energized, and closes when de-energized.
• Harvest pressure regulating valve (HPR valve). This is a
pressure regulating valve which modulates open and
closed, based on the refrigerant pressure at the outlet
of the valve. The valve closes completely and stops
refrigerant flow when the pressure at the outlet rises
above the valve setting.
• The harvest pressure regulating valve is not adjustable.
FREEZE CYCLE
The HPR system is not used during the freeze cycle.
The HPR solenoid is closed (de-energized), preventing
refrigerant flow into the HPR valve.
HARVEST CYCLE
During the harvest cycle, the check valve in the discharge
line prevents refrigerant in the remote condenser and
receiver from back feeding into the evaporator and
condensing to liquid.
The HPR solenoid is opened (energized) during the harvest
cycle, allowing refrigerant gas from the top of the receiver
to flow into the HPR valve. The HPR valve modulates open
and closed, raising the suction pressure high enough
to sustain heat for the harvest cycle, without allowing
refrigerant to condense to liquid in the evaporator.
In general, harvest cycle suction pressure rises, then
stabilize. Exact pressures vary from model to model. Refer
to cycle time/24 hour ice production and operational
pressure charts.
Part Number 000018624 Rev 00 4/26 Modular - 127

Refrigerant Recovery/Evacuation
DEFINITIONS
Recover
To remove refrigerant, in any condition, from a system and
store it in an external container, without necessarily testing
or processing it in any way.
Recycle
To clean refrigerant for re-use by oil separation and single
or multiple passes through devices, such as replaceable
core filter-driers, which reduce moisture, acidity and
particulate matter. This term usually applies to procedures
implemented at the field job site or at a local service shop.
Reclaim
To reprocess refrigerant to new product specifications (see
below) by means which may include distillation. A chemical
analysis of the refrigerant is required after processing to be
sure that product specifications are met. This term usually
implies the use of processes and procedures available only
at a reprocessing or manufacturing facility.
Chemical analysis is the key requirement in this definition.
Regardless of the purity levels reached by a reprocessing
method, refrigerant is not considered “reclaimed” unless it
has been chemically analyzed and meets ARI Standard 700
(latest edition).
New Product Specifications
This means ARI Standard 700 (latest edition). Chemical
analysis is required to assure that this standard is met.
Part Number 000018624 Rev 00 4/26 Modular - 131
REFRIGERANT REUSE POLICY
Koolaire recognizes and supports the need for proper
handling, re-use, and disposal of refrigerants. Koolaire
service procedures require recapturing refrigerants, not
venting them to the atmosphere.
It is not necessary, in or out of warranty, to reduce or
compromise the quality and reliability of your customers’
products to achieve this.
Important
Koolaire assumes no responsibility for use of
contaminated refrigerant. Damage resulting from the
use of contaminated, recovered, or recycled refrigerant
is the sole responsibility of the servicing company.
Koolaire approves the use of:
1. New Refrigerant
• Must be of original nameplate type.
2. Reclaimed Refrigerant
• Must be of original nameplate type.
• Must meet ARI Standard 700 (latest edition)
specifications.
3. Recovered or Recycled Refrigerant
• Must be recovered or recycled in accordance with
current local, state and federal laws.
• Must be recovered from and re-used in the same
Koolaire product. Re-use of recovered or recycled
refrigerant from other products is not approved.
• Recycling equipment must be certified to ARI
Standard 740 (latest edition) and be maintained to
consistently meet this standard.
132 - Modular Part Number 000018624 Rev 00 4/26
4. Recovered refrigerant must come from a
“contaminant-free” system. To decide whether the
system is contaminant free, consider:
• Type(s) of previous failure(s)
• Whether the system was cleaned, evacuated and
recharged properly following failure(s)
• Whether the system has been contaminated by
this failure
• Compressor motor burnouts and improper past
service prevent refrigerant re-use.
• Refer to “Determining Severity of Contamination”
on page 140 to test for contamination.
5. “Substitute” or “Alternative” Refrigerant
• Must use only Koolaire-approved alternative
refrigerants.
• Must follow Koolaire-published conversion
procedures.
Part Number 000018624 Rev 00 4/26 Modular - 133
RECOVERY AND RECHARGING PROCEDURES
Do not purge refrigerant to the atmosphere. Capture
refrigerant using recovery equipment. Follow the
manufacturer’s recommendations.
Important
Koolaire assumes no responsibility for the use of
contaminated refrigerant. Damage resulting from
the use of contaminated refrigerant is the sole
responsibility of the servicing company.
Important
Replace the liquid line drier before evacuating and
recharging. Use only a Koolaire (O.E.M.) liquid line
filter drier to prevent voiding the warranty.
CONNECTIONS
1. Suction side of the compressor through the suction
service valve.
2. Discharge side of the compressor through the
discharge service valve.
3. Liquid side through the liquid line drier.
134 - Modular Part Number 000018624 Rev 00 4/26
SELFCONTAINED RECOVERY/EVACUATION
1. Cycle the toggle switch Off.
2. Install manifold gauge, scale and recovery unit or two-
stage vacuum pump and open high, low and charging
ports.
3. Perform recovery or evacuation:
A. Recovery: Operate the recovery unit as directed
by the manufacturer’s instructions.
B. Evacuation prior to recharging: Pull the system
down to 500 microns. Then, allow the pump to
run for an additional half hour. Turn off the pump
and perform a standing vacuum leak check.
4. Follow the Charging Procedures.
Part Number 000018624 Rev 00 4/26 Modular - 135
CHARGING PROCEDURES
Important
The charge is critical on all Koolaire machines. Use
a scale or a charging cylinder to ensure the proper
charge is installed.
1. Cycle the toggle switch Off.
2. Isolate the vacuum pump valve, low side and high
side access valves from the refrigeration system. The
refrigerant charging access valve remains open.
3. Open the high side manifold gauge valve.
4. Open the refrigerant cylinder and add the proper
refrigerant charge (shown on nameplate) through the
liquid line drier.
,
Caution
Damage may occur when charging liquid into the front
discharge line access port.
Replacement driers have a Schrader valve built into the
inlet of the drier. Filter driers without an access port
must be replaced with the current OEM part before
recharging the ice machine. All Liquid refrigerant must
be added through the liquid line drier access port.
5. Let the system “settle” for 2 to 3 minutes.
6. Cycle the toggle switch On.
NOTE: Manifold gauge set must be removed properly to
ensure that no refrigerant contamination or loss occurs.
136 - Modular Part Number 000018624 Rev 00 4/26
7. Make sure that all of the vapor in the charging hoses
is drawn into the ice machine before disconnecting
the charging hoses.
A. Run the ice machine in freeze cycle.
B. Remove the high side low loss fitting from the
liquid line filter drier.
C. Open the high and low side valves on the
manifold gauge set. Any refrigerant in the lines
will be pulled into the low side of the system.
D. Allow the pressures to equalize while the ice
machine is in the freeze cycle.
E. Remove the hoses from the ice machine and
install the caps.

Do not purge refrigerant to the atmosphere. Capture
refrigerant using recovery equipment. Follow the
manufacturer’s recommendations.
Important
Koolaire assumes no responsibility for the use of
contaminated refrigerant. Damage resulting from
the use of contaminated refrigerant is the sole
responsibility of the servicing company.
Important
Replace the liquid line drier after recovering the
refrigerant and before evacuating and recharging.
Use only a Koolaire (O.E.M.) liquid line filter drier to
prevent voiding the warranty.
Important
Recovery/evacuation of a remote system requires
connections at four points for complete system
evacuation.
MAKE THESE CONNECTIONS:
• Suction side of the compressor through the suction
service valve.
• Discharge side of the compressor through the
discharge service valve.
• Receiver outlet service valve, which evacuates the
area between the check valve in the liquid line and the
pump down solenoid.
138 - Modular Part Number 000018624 Rev 00 4/26
• Access valve on the discharge line quick-connect
fitting, located on the outside of the compressor/
evaporator compartment. This connection evacuates
the condenser. Without it, the magnetic check
valves would close when the pressure drops during
evacuation, preventing complete evacuation of the
condenser.
NOTE: Koolaire recommends using an access valve core
removal and installation tool on the discharge line quick-
connect fitting. This permits access valve core removal.
This allows for faster evacuation and charging, without
removing the manifold gauge hose.
REMOTE CONDENSER RECOVERY/EVACUATION
1. Stop the ice machine.
2. Install manifold gauge set, scale and recovery unit or
two-stage vacuum pump.
3. Open high and low side on the manifold gauge set.
4. Perform recovery or evacuation:
A. Recovery: Operate the recovery unit as directed
by the manufacturer’s instructions.
B. Evacuation prior to recharging: Pull the system
down to 500 microns. Then, allow the pump to
run for an additional hour. Turn off the pump and
perform a standing vacuum leak check.
NOTE: Check for leaks with an electronic leak detector
after charging the ice machine.
5. Follow the Remote Charging Procedures.
Part Number 000018624 Rev 00 4/26 Modular - 139
REMOTE CHARGING PROCEDURES
1. Close the vacuum pump valve and the low side
manifold gauge valve.
2. Open the refrigerant cylinder and add the proper
refrigerant charge (shown on nameplate) into the
system high side (receiver outlet valve/liquid line drier
and/or liquid line quick-connect fitting).
3. If the high side does not take the entire charge, close
the high side on the manifold gauge set and start the
ice machine. Add the remaining charge through the
low side until the machine is fully charged.
NOTE: If an access valve core removal and installation
tool is used on any of the access valves, reinstall the cores
before disconnecting the access tool and hose.
4. Verify all of the vapor in the charging hoses is drawn
into the refrigeration system before disconnecting the
charging hoses.
A. Run the ice machine in freeze cycle.
B. Remove the high side low loss fitting.
C. Open the high and low side valves on the
manifold gauge set. Any refrigerant in the lines
will be pulled into the low side of the system.
D. Allow the suction pressures in the refrigeration
system and the manifold gauge set to equalize
while the ice machine is in the freeze cycle.
E. Isolate and remove the low side hose.
F. Install access valve caps.

System Contamination Cleanup
This section describes the basic requirements for restoring
contaminated systems to reliable service.
Important
Koolaire assumes no responsibility for the use of
contaminated refrigerant. Damage resulting from
the use of contaminated refrigerant is the sole
responsibility of the servicing company.
DETERMINING SEVERITY OF CONTAMINATION
System contamination is generally caused by either
moisture or residue from compressor burnout entering the
refrigeration system.
Inspection of the refrigerant usually provides the first
indication of system contamination. Obvious moisture or
an acrid odor in the refrigerant indicates contamination.
If harmful levels of contamination are suspected, perform
the following procedure.
1. Remove the refrigerant charge from the ice machine.
2. Remove the compressor from the system.
3. Check the odor and appearance of the oil.
4. Inspect open suction and discharge lines at the
compressor for burnout deposits.
5. If no signs of contamination are present, perform
an acid oil test to determine the type of cleanup
required.

CLEANUP PROCEDURE
Mild System Contamination
1. Replace any failed components.
2. If the compressor is good, change the oil.
3. Replace the liquid line drier.
NOTE: If the contamination is from moisture, use heat
lamps during evacuation. Position them at the compressor,
condenser and evaporator prior to evacuation. Do not
position heat lamps too close to plastic components, or
they may melt or warp.
4. Follow the normal evacuation procedure, except
replace the evacuation step with the following:
A. Pull vacuum to 1000 microns. Break the vacuum
with dry nitrogen and sweep the system.
Pressurize to a minimum of 5 psig.
B. Pull vacuum to 500 microns. Break the vacuum
with dry nitrogen and sweep the system.
Pressurize to a minimum of 5 psig.
C. Change the vacuum pump oil.
D. Pull vacuum to 500 microns. Run the vacuum
pump for 1/2 hour on self-contained models, 1
hour on remotes.
NOTE: You may perform a pressure test as a preliminary
leak check. You should use an electronic leak detector after
system charging to be sure there are no leaks.
5. Charge the system with the proper refrigerant to the
nameplate charge.
6. Operate the ice machine.
Part Number 000018624 Rev 00 4/26 Modular - 143
SEVERE SYSTEM CONTAMINATION CLEANUP
PROCEDURE
1. Remove the refrigerant charge.
2. Remove the compressor and inspect the refrigeration
lines. If burnout deposits are found, install a new
harvest valve, replace the manifold strainer, TXV and
harvest pressure regulating valve.
3. Wipe away any burnout deposits from suction and
discharge lines at compressor.
4. Sweep through the open system with dry nitrogen.
5. Install a new compressor and new start components.
6. Install suction line filter-drier in front of compressor.
7. Install an access valve at the inlet of the suction line
drier.
8. Install a new liquid line drier.
9. Follow the normal evacuation procedure, except
replace the evacuation step with the following:
A. Pull vacuum to 1000 microns. Break the vacuum
with dry nitrogen and sweep the system.
Pressurize to a minimum of 5 psig.
B. Change the vacuum pump oil.
C. Pull vacuum to 500 microns. Break the vacuum
with dry nitrogen and sweep the system.
Pressurize to a minimum of 5 psig.
D. Change the vacuum pump oil.
E. Pull vacuum to 500 microns. Run the vacuum
pump for 1 additional hour.
NOTE: You may perform a standing vacuum test to make a
preliminary leak check. You should use an electronic leak
detector after system charging to be sure there are no
leaks.
144 - Modular Part Number 000018624 Rev 00 4/26
10. Charge the system with the proper refrigerant to the
nameplate charge.
11. Operate the ice machine for one hour. Then, check
the pressure drop across the suction line filter-drier.
A. If the pressure drop is less than 1 psig the filter-
drier should be adequate for complete cleanup.
B. If the pressure drop exceeds 1 psig, change the
suction line filter-drier and the liquid line drier.
Repeat until the pressure drop is acceptable.
12. Operate the ice machine for 48 – 72 hours. Replace
the suction line and liquid line drier if necessary.
13. Follow normal evacuation procedures.
LIQUID LINE FILTER DRIERS
The filter-driers used on Koolaire ice machines are
manufactured to Koolaire specifications and have an
access fitting for charging with refrigerant. A Koolaire
drier also has dirt-retaining filtration, with fiberglass filters
on both the inlet and outlet ends. This is very important
because ice machines have a back-flushing action that
takes place during every Harvest cycle.
A Koolaire filter-drier has high moisture and acid removal
capability.
The size of the filter-drier is important. The refrigerant
charge is critical. Using an improperly sized filter-drier
will cause the ice machine to be improperly charged with
refrigerant.
Important
Driers are covered as a warranty part. The drier must
be replaced any time the system is opened for repairs.
Part Number 000018624 Rev 00 4/26 Modular - 145
REPLACING PRESSURE CONTROLS WITHOUT
REMOVING REFRIGERANT CHARGE
This procedure reduces repair time and cost. Use it when
any of the following components require replacement, and
the refrigeration system is operational and leak-free.
• Fan cycle control
• High pressure cut-out control
• High side access valve
• Low side access valve
1. Disconnect power to the ice machine.
2. Follow all manufacturers’ instructions supplied with
the pinch-off tool. Position the pinch-off tool around
the tubing as far from the pressure control as feasible.
(See the figure on next page.) Clamp down on the
tubing until the pinch-off is complete.
n
Warning
Do not unsolder a defective component. Cut it out of
the system. Do not remove the pinch-off tool until the
new component is securely in place.
3. Cut the tubing of the defective component with a
small tubing cutter.
4. Solder the replacement component in place. Allow
the solder joint to cool.
5. Remove the pinch-off tool.
6. Re-round the tubing. Position the flattened tubing in
the proper hole in the pinch off tool. Tighten the wing
nuts until the block is tight and the tubing is rounded.
NOTE: The pressure controls will operate normally once
the tubing is re-rounded. Tubing may not re-round 100%.

Cycle Times, 24 Hr. Ice Production and
Refrigerant Pressure Charts
These charts are used as guidelines to verify correct ice
machine operation.
Accurate collection of data is essential to obtain the
correct diagnosis.
• Production and cycle times are for dice cube - Half dice
cube cycle times can be 1-2 minutes faster depending
on model and ambient temperature.
• Ice production checks that are within 10% of the chart
are considered normal. This is due to variances in
water and air temperature. Actual temperatures will
seldom match the chart exactly.
• Refer to “Operational Analysis Chart” for the list
of data that must be collected for refrigeration
diagnostics.
• Zero out manifold gauge set before obtaining pressure
readings to avoid mis-diagnosis.
• Discharge and suction pressure are highest at the
beginning of the cycle. Suction pressure will drop
throughout the cycle. Verify the pressures are within
the range indicated.
• Record beginning of freeze cycle suction pressure one
minute after the water pump energizes.
