REFRIGERANT CHANGES
REFRIGERANT CHANGES
In compliance with EPA regulations requiring the transition away from R-404A refrigerant, effective January 1, 2026, we
are updating the refrigerants used in our units to more environmentally sustainable options. Larger remote units will
utilize R449A refrigerant, while self-contained units will operate with R-290 refrigerant. Identification of these units will
be facilitated through multiple indicators: the final two digits of the model number (as referenced on the preceding page),
the data tag, and stickers affixed to line-sets. Additionally, R-290 units will feature specific warning labels as detailed
below.
R449 refrigerant possesses characteristics closely resembling those of R-404A, requiring minimal modifications to
existing units aside from a TXV replacement.
In contrast, R-290 exhibits distinct properties that necessitate different considerations.
What is R290?
R290 is Propane
•
Extremely Pure
•
Highly Flammable
•
NO ADDED ODORANT
(no smell)
•
Heavier than air (pools up in low areas)
R290 SAFTEY HAZARDS
Fire/Explosion
Asphyxiation
•
You cannot get enough air to breath – there’s not enough oxygen
•
R404 and R449 are also asphyxiants

ELEVATION SERIES CIM CUBERS
INSTALLATION GUIDELINES
Installation Guidelines
For proper operation of the ice machine, the following installation guidelines must be followed by a Qualified
Refrigeration Technician. Failure to do so may result in loss of production capacity, premature part failures,
and may void all warranties.
Reference the installation parameters prior to installing the machine. Ice-O-Matic assumes no responsibility for
improperly installed equipment. Excessive time required for service or time for units requiring removal for
service of inaccessible equipment will be the sole responsibility of the equipment owner.
Ambient Operating Temperature
Minimum operating temperature:
Air cooled units 50°F (10°C)
Remote units -20°F (- 29°C)
Maximum operating temperature:
Air cooled Units 100°F (38°C) (60 Hz.), 110°F (43°C) (50 Hz.).
Remote units 120° F (49°C)
Note: Ice-O-Matic ice-makers and dispensers are not approved for outdoor installation
Incoming Water Supply
WARNING: Connect to unheated potable water supply only!
(See Electrical and Plumbing diagrams for line sizing)
Minimum incoming water temperature: 40°F (4.5°C)
Maximum incoming water temperature: 100°F (38°C)
Minimum incoming water pressure: 20 psi (1.4 bar, 0.138MPa)
Maximum incoming water pressure: 80 psi (5.5 bar, 0.552MPa)
Note: if water pressure exceeds 80 psi (5.5 bar), a water pressure regulator must be installed
All water supply lines must be installed per local codes. Use 3/8 inch O.D. minimum on air cooled machines.
On water cooled machines 3/8 inch O.D. minimum tubing must be run to the condenser. The water supply for the
machine can “T” off from the condenser line using 3/8 inch O.D. minimum tubing. Make 2 coils of extra tubing
so that the machine can be pulled away from the wall if service is needed.
Water Filtration/Treatment
A water filter system should be installed with the ice machine. Refer to Ice-O-Matic water filter
specification sheet.
Reverse Osmosis (RO) water can be very acidic and can attack the evaporator and other metal in the ice
machine. Because the RO process removes all minerals and metals from the water it can promote the faster
growth of microbial mold and slime. If RO water is used, Ice-O-Matic recommends the water pH verified to be
a neutral 7.0 to minimize the corrosive effects. Incorrect cleaners, sanitizers, and RO water that does not have a
neutral pH could void the machine’s warranty.
6
ELEVATION SERIES CIM CUBERS
INSTALLATION GUIDELINES
Drains
All drain lines must be installed per local codes. Flexible tubing is not recommended. Route bin drain, purge
drain and water condenser drain individually to a floor drain. The use of condensate pumps for draining water is
not recommended.
Ice-O-Matic assumes no responsibility for improperly installed equipment. This may void the warranty.
Note: The Purge Drain Fitting is plastic: DO NOT apply heat to the purge drain area;
DO NOT over-tighten drain connection.
The purge drain should be a minimum of 3/4 inch
O.D. tubing, and properly vented. The condenser drain on water cooled units should be 1/2 inch O.D.
minimum. The drain line fittings on Ice-O-Matic bins are 3/4 FPT. The bin drain should be a minimum of
3/4 inch O.D. and properly vented. Cold water drains should be insulated to prevent condensation from
forming.
It is not recommended that a Drain pump be used on CIM Model Ice machines
Clearance Requirements
Self-contained air-cooled ice machines should have a minimum of 6 inches (15cm) of clearance at the rear, top and
sides for proper air circulation and adequate space for serviceability.
Self-contained air-cooled ice machines exhaust air out the top and right side. There are two alternative air exhaust
options. Option A (top exhaust bias): minimum of 6 inches (15cm) of clearance at the rear and top of the ice
machine for proper function at maximum operating conditions. Option B (side exhaust bias): minimum of 6 inches
(15cm) of clearance at the rear and right side of the ice machine with a minimum of 3 inches (7.5cm) of clearance
at the top for proper function at maximum operating conditions.
CAUTION: Improper ventilation will cause unit to Malfunction and Service will not be covered under
Warranty
Appropriate space should be allowed for proper serviceability of the machine.
Excess time to gain access for serviceability is not covered under warranty.
Stacking
Ice-O-Matic does not endorse stacking ice machines.

ELEVATION SERIES CIM CUBERS
INSTALLATION GUIDELINES
Dispenser Application
A thermostatic bin control kit is required when installing the CIM Cube ice machine on a dispenser. The use of a bin top
depends on the application and should be secured to the dispenser accordingly.
Electrical Specifications
Check the serial plate at the rear of the ice machine to verify correct voltage and circuit breaker size. The ice machine
should operate on a dedicated circuit. For European installations, the electrical supply fixed wiring must have a
disconnect mechanism with at least 3mm separation in all poles.
These ice machines do not include an electrical cord set and are designed for permanent connection as approved by
relevant agencies
.
Units are not approved for GFI outlets. Electrical connections or cord installation must be performed by a
qualified electrician to prevent electrical hazards.
Adjustments
• Level the machine within 1/8 inch in all directions.
• Inspect the water in the Water Sump to confirm proper level.
• Evaluate the ice bridge thickness and adjust the Float Switch Housing Assembly as necessary.
• If water cooled, check the Water Regulating Valve adjustment.
Note: These adjustments should be completed by a Qualified Service Technician during unit installation;
they are not covered under factory warranty.
Secure the ice machine onto the bin or dispenser using mounting straps provided. Ensure the back of the ice
machine aligns flush with the bin's back. For proper operation, the Bin Door should remain stable when open.
Installing the ice machine too far forward may lead to instability, causing the door to close unexpectedly.
When mounting on bins or dispensers not manufactured by Ice-O-Matic, refer to the manufacturer’s
installation instructions. Ice-O-Matic does not accept responsibility for damage or injury resulting from
improper placement that causes the bin door to close unexpectedly.

REMOTE CONDENSER GUIDELINES
8
Remote Condenser Installation
For proper operation of the ice machine, the following installation guidelines must be followed. Failure to do
so may result in loss of production capacity, premature part failure, and may void all warranties.
Use the following for planning the placement of the remote condenser relative to the ice machine
Location Limits
Remote condenser location must not exceed ANY
of the following:
The maximum rise from the ice machine to the remote condenser is 35 physical feet.
The maximum drop from the ice machine to the remote condenser is 10 physical feet.
The physical line set maximum length is 75 ft.
The calculated line set maximum length is 100 ft.
Ambient operating temperatures:
-20°F (-28.9°C) to 120°F (48.9°C)
Limitations on line-set runs
Maximum Rise is 35’
Maximum Drop is 10’
Maximum Run Is 100’
Formula for calculating Maximum run is as follows.
Formula for calculating Maximum run is as follows.
RISE
Rise x 1.7 + Horizontal Run = < 100’
Example: 35’ x 1.7 + 40’ = 99.5‘ this is < 100 so it is ok.
NOT TO EXCEED 100 CALCULATED FEET
(35 ft. x 1.7) + (40 ft.) = 99.5 calculated feet line run
35 ft. rise
40 ft. horizontal
ELEVATION SERIES CIM CUBERS
REMOTE CONDENSER GUIDELINES
9
Drop:
(10 ft. x 6.6) + (34 ft.) = 100 calculated feet line run
Example: 10’ x 6.6 + 30’ = 90’ This is < 100 so it is ok.
Configurations that do NOT meet these requirements must receive written authorization from Ice-O-Matic. This includes
multi-pass or rack system remote condensers.
Remote Condenser Location
Pre-charged line sets are available in 25-, 40- or 75-foot lengths to connect the ice machine to the remote
condenser. Select the best available location, protecting the remote condenser from extremes of dirt, dust and
sun. Meet all applicable building codes. The services of a licensed electrician may be required. Clearances
required for the RCA/RGA Condensers are 48” above and 18” on all side of the unit for proper air flow.
Roof Attachment
Install and attach the remote condenser to the roof of the building using the methods and practices of
construction that conform to the local building codes, including having a roofing contractor secure the
remote condenser to the roof.
Have an electrician connect the remote condenser fan motor wires to the ice machine using the junction
box at the back of the machine.
NOTE: REMOTE LINES MUST NOT RISE AND DROP IN THE SAME RUN
Have a roofing contractor cut a minimum hole for the refrigerant lines of 2.50 inch. Check local codes, a
separate hole may be required for the electrical power to the condenser.
CAUTION: DO NOT KINK OR CRIMP REFRIGERANT TUBING WHEN INSTALLING IT.

Pre-charged Line Set Routing
CAUTION: Do not connect the pre-charged tubing until all routing and forming of the tubing has
been completed. See the coupling instructions for connecting information.
Each set of pre-charged tubing refrigerant lines consists of a 3/8” diameter liquid line and 1/2-inch
diameter discharge line. Both ends of each line have quick connect couplings, one end of the line set has
a Schrader valve connection.
Route refrigerant lines through the roof opening in straight paths when possible. Keep excess tubing inside the
building, spiraling it horizontally to prevent traps. Ensure the roofing contractor seals roof holes according to
local codes.
CAUTION: The couplings on the sets of pre-charged lines are self-sealing when installed properly.
Carefully follow the instructions in the Remote Condenser manual.
Verify all remote components and refrigerant types match before connecting line-
sets. Mixing refrigerants voids the warranty and any related repairs will not be
covered.
The following remote ice makers incorporate the Mixing Valve in the Condenser. This configuration allows
up to a 100-foot calculated remote line set run. Reference the diagram on the Previous pages to calculate
the maximum 100 ft. line set run. Maximum actual line set run is limited to 75ft.

the cycle as explained in this section.
Bridge Thickness Adjustment
Once the unit has gone through a harvest cycle,
verify the bridge thickness (3/16” thick for units
less than 400 lbs. and 1/8” for 400 lbs. and above)
across the middle of the ice slab on the second
batch produced. The ice thickness can be changed
on the Float Housing by turning the adjustment
clockwise to decrease the bridge thickness and
counterclockwise to increase the bridge thickness.
You will hear a “click” with each adjustment. It is
recommended adjustments be made one or two
“clicks” at a time.

Adjustment Switch Block
Four adjustments can be made on the block. Extended Purge, Bin Thermostat Kit add-on and
Cleaning Needed Reminder.
Standard Purge time during a Defrost Cycle is set at 7 seconds. To add an additional 40 seconds
to the purge time, move Switch 1 to the right, to the ON position.
Should the unit be installed on top of a dispenser, a Bin Thermostat Kit is required. Following the
instruction that comes with the kit, switch 2 needs to be moved to the ON position to tell the pro-
gram to read the Bin Thermostat. The LED beside the Bin Stat Connection will then illuminate.
Switch 3 on the block is for the Cleaning Needed Reminder. When in the OFF position, the
default setting for the clean reminder is 6 months. When Switch 3 is moved to the ON position,
the Reminder is set for every 3 months. This is recommended should the unit be installed in a
hardwater location to help with production levels. Switch 4 turns off the clean reminder light.
(not recommended).
Low Voltage connection (12VDC) for Control Switches
This Molex connects the Magnetic Curtain Switch(es), High Float Switch, Low Float Switch and
Remote Configuration Switch to the Board. The LED’s associated to each switch will illuminate
when the contacts for each are closed. The Remote Configuration LED will be illuminated when
the Smart Harness reads the unit has a Remote Condenser. The fill light indicates unit is over 800lbs
and has to fill 2 times with water. Config1 (D2), (D16),and (D17) are not used.
Thermistor Connection
The Thermistor is used to gauge the water temperature in the Sump and is used to activate the
Anti-Slush Cycle. When the water temperature reaches 36 degrees F during the first 3 cycles
following a full bin situation, being restarted after a loss of power or turned off, the Water Pump
will be turned off for 20 seconds to help prevent slushing of the water in the Sump. An Anti-Slush
will also be performed any time the water temperature reaches 28 degrees F. Control Boards
after ser. 2106 Shuts down the pump at 38° F for 20 seconds every cycle.
Control Relays
The six Control Relays send voltage out to the individual components during the operation of the
unit. Relay 1 energizes the Fan(s) on self-contained air-cooled units or the Liquid Line Solenoid
on Remotes. Relay 2 energizes the Compressor through the Contactor (and Fan Motor on
Remotes). Relay 3 energizes the Hot Gas Valve and Harvest Assist Assembly during the Harvest
Cycle. Relay 4 energizes Water Inlet Valve. Relay 5 energizes the Purge Valve. Relay 6 energizes
the Water Pump.
Line Voltage Connection
The Line Voltage Molex connects each component to the Board. See the wiring diagram for each
unit to see the wiring colors associated with each component.

The High Float Switch is used to control the water level for ice making, cleaning and
sanitizing. The Float will rise with the water level, opening the contact of the switch and signal
the Board to close the Water Inlet Valve. The LED associated with the High Float switch will be
ON when the contacts of the switch are closed and will turn OFF when the contacts open. The
Low Float Switch is used to determine when the unit is ready to go into the Harvest Cycle during
ice pro‐ duction and when the Sump has been emptied of cleaner or sanitizer during the
Cleaning Cycle.
High and Low Float Switch Operation
The High Float Switch is used to control the water level for ice making, cleaning and
sanitizing. The Float will rise with the water level, opening the contact of the switch and signal
the Board to close the Water Inlet Valve. The LED associated with the High Float switch will be
ON when the contacts of the switch are closed and will turn OFF when the contacts open. The
Low Float Switch is used to determine when the unit is ready to go into the Harvest Cycle during
ice pro‐ duction and when the Sump has been emptied of cleaner or sanitizer during the
Cleaning Cycle
The LED associated with the Low Float Switch operates the same as the LED for the High Float
Switch. The LED will ILLUMINATE when the contact of the float is closed and will turn OFF when
the contacts are open. The Thermistor monitors the water temperature in the Sump during the
Freeze Cycle. At 38°F the system initiates an “Anti‐slush” shutdown of the Water Pump for 20
seconds when the water temperature reaches 38°F to decrease the risk of slushing in the Sump.
Additionally, the system will perform an anti‐slush shutdown of the Water Pump whenever the
water temperature reaches 28°F.
Troubleshooting
When the High and Low Floats are in the down position, the contacts for the switches are
closed and the LEDs on the Board should be illuminated.
Low Float Switch LED

As the water level rises, the floats rise with it and the contacts of the switches will open
and the LEDs on the Board will go OFF. This can be verified by removing the Sump and checking
first the LEDs on the Board. Without the presence of water, both floats should be in the down
position and the LEDs on the Board should be illuminated. If one or both LEDs are OFF,
disconnect the Float Switches at the connectors along with the Thermistor and remove the
Float Housing by gently pulling down on it from the ice drop zone.
Thermistor Connector

Open the housing and examine each float for movement of the float and cleanliness. With a
meter set on continuity, verify the contacts on the float open and close with movement of the
float. If float is clean and contacts do not change with float movement, replace Float Switch
Housing Assembly. If one or both of the LEDs remain OFF with Float Switches that are known to
be good, the Board or Wiring Harness may be the issue. Keep in mind: sometimes the LEDs will
be on even if the unit isn’t working. If there’s resistance in the switch, a small amount of voltage
might pass through—just not enough for the control to operate.

The Bridge Thickness on units under 400# production should be 3/16” while units over 400# pro‐
duction should be 1/8” thick when measured across the middle of the plate. Minor Adjustments
can be made to the bridge thickness by moving the Water Level Adjustment Arm of the Float
Housing up for a thicker bridge or down for a thinner bridge. This adjustment can be made at
any time during the freeze or defrost cycle and the results verified on the following cycle.
Recommended Float Setting Chart.
To make this adjustment the water trough, Splash guard, and lower water curtain will need to be
removed. Pull gently down on the float, the float will come out through the bottom of the machine and this
setting can then be made.

Water Pump
Operation
Relay 6 (LED ON) powers the Water Pump after a 30‐second evaporator pre‐chill during the Freeze
Cycle. At the start of the Freeze Cycle following shutdown (OFF or Bin Full), the Water Pump pauses for
20 seconds to prevent sump slushing before running normally. The pump operates continuously during
the Cleaning Cycle once the Sump is filled.
Troubleshooting
If Relay 6 LED is ON but the Water Pump does not run, verify line voltage between the Yellow
and Blue wires on the Molex. If line voltage isn’t found, verify connection of Molex to Board and
reverify. If no voltage is found, the issue is the Board. If line voltage is found, verify line voltage
at Water Pump connector. If no voltage is found, the issue is the wiring or connectors. If line
Voltage is found, but the Water Pump won’t spin, the issue is the Water Pump. Clean or replace
as required.
When verifying voltage out of Board, check at the Blue and Yellow wires.

connect. Reinstall the Water Pump by first making the electrical connection, the push Pump up
pointing the Foot at the right rear corner and turn clockwise to secure.
Water Distribution Tube
The Water Distribution Tube has an inner tube and an outer tube. The water enters through the
inner tube and sprays the water up into the outer tube relieving the pressure on the water.
Gravity takes over and the water runs out the outer tube holes pointed down. The water runs
smoothly and evenly over the Evaporator.

Water Inlet Valve
Operation
Relay 4 on the Board (LED ON) energizes the Valve first on initial startup to fill the Sump until
the contacts of the High Float Switch open, indicating a proper amount of water for ice making.
The purpose is to verify water supply before starting the unit. After the initial cycle is complete,
the Valve will be energized during the Harvest Cycle and if needed, energized during the Pre‐
Chill to complete filling the Sump (See Sequence of Operation pg. 9). In either case, Relay 4 will
be illuminated when the Water Inlet Valve is energized. During the Cleaning and Sanitizing Cycle
the Water Inlet Valve will be energized several times during the rinse and purge portion of the
cycle (see Cleaning Instructions pg. 56).
Troubleshooting
The High Float Switch contacts must open within 5 minutes. If Relay 4 is on but the Water Inlet Valve
doesn’t open, first check the water supply. Then check for line voltage between the (tan and blue)
Molex wires. If absent, the Board is faulty; if present, check voltage at the Water Inlet Valve coil. No
voltage means faulty wiring or connectors. If voltage is present, test coil resistance—no resistance
indicates an open coil, so replace the valve. If the coil is fine, inspect and clean or replace the Water
Inlet Valve as needed, and check incoming water supply and filters for blockages.

Voltage can also be verified at the connector at the coil of the Water Inlet Valve.
ELEVATION SERIES CIM CUBER
PURGE VALVE
53
Purge Valve
Operation
The Purge Valve is located on the back of the Evaporator. The Valve should open when energized
by Relay 5 on the Board (LED ON) during the Harvest Cycle to help empty the mineral laden
water (see Sequence of Operation pg. 9) and during the Cleaning/Sanitizing Cycle (see Cleaning
Instructions pg. 56).
Troubleshooting
The Purge Valve, located behind the Evaporator, opens when Relay 5 (LED ON) is energized during the
Harvest and Cleaning/Sanitizing Cycles to remove mineral‐rich water. If the valve does not open when
Relay 5's LED is lit, unplug the coil connector and check for line voltage. If there is none, check the
output at the board's Molex (pink and blue wires). No voltage means the board is faulty; if voltage is
present, the issue is with the wiring between the Molex and the valve connector.
Voltage can also be verified at the connector at the coil on the Purge Valve.

Harvest Assist Assembly/Hot Gas Valve
Operation
The Harvest Assist Assembly is mounted to the back of the Evaporator Assembly. It is energized
by Relay 3 along with the Hot Gas Valve. As the unit enters the Harvest Cycle, Relay 3 will
illuminate indicating voltage is being sent to the Harvest Assist Assembly and the probe will be
pushed forward to meet the ice slab. As the Evaporator warms, the Probe on the Harvest Assist
will move forward to help release the ice from the plate. As the ice slab falls it will open the
Magnetic Curtain Switch contacts. Relay 3 will then be de‐energized, and the Harvest Assist will
automatically return to the starting position.
Troubleshooting
The Harvest Assist Assembly is powered by the Hot Gas Valve via Relay 3 during Defrost. To test, enter
Diagnostics by holding Power and Wash for 6 seconds, then quickly press both Power and Clean to
start Harvest (R2‐R6 LEDs should light up). Ensure Relay 3’s LED is on and check voltage between Blue
and Red at Molex. No voltage suggests a problem with the Board or Molex. If voltage is present, check
at the Harvest Assist connector. If voltage exists but the probe doesn't advance, the Harvest Assist is
faulty.

The Magnetic Curtain Switch is a proximity switch that closes the contacts when the Splash
Curtain closes. LEDs on the Board indicate a closed switch when illuminated.
Note: In 48” units there is a curtain magnet and proximity switch for both plates, on the left and
right sides of the unit.
Troubleshooting
Should the LEDs on the Board be off when the Splash Curtain is closed, first verify the magnet is
in place on the Splash Curtain and the Wiring Harness is properly connected at the Switch and at
the Board. If all is verified, use a different magnet against the switch. If it still will not close,
replace the Magnetic Curtain Switch. Keep in mind: sometimes the LEDs will be on even if the
unit isn’t working. if there’s resistance in the switch, a small amount of voltage might pass
through—just not enough for the control to operate.

Troubleshooting
High Pressure Cut-out
The High‐Pressure Cut‐out opens at 450 psig to de‐energize the Contactor and shutdown the
Compressor. The control recloses at 350 psig. Should the control open during the Freeze Cycle,
the unit may go into Error 1 state, indicating the Freeze Cycle has run for more than 1 hour. To
quickly check the unit operating pressure, run a Diagnostic Cycle with stub gauges on the unit.

refrigerant over charge can be the cause. Note R-290 Models will have a 350psi open and a
250 psi close.
Fan Cycling Control
The Fan Cycle Control is designed to close at 250 psig and open at 190 psig, helping regulate head
pressure when conditions are cool. If the control activates at pressures outside this range, it should
be replaced. R‐290 units do not include a fan cycle control. NOTE: R-290 units will not have a fan
cycling control.

Fan Motor
Operation
The Fan Motor (Self‐Contained Air‐Cooled Units) is Mounted to the Fan Shroud covering the Con‐
denser at the rear of the unit. It is energized by Relay 1 and controlled by the Fan Cycling Switch.
The Switch should close at 250 psi of head pressure and power the Motor. The Fan Cycle Switch
(if equipped) should open at 190 psi of head pressure, and the Fan Motor will de‐energize.
Troubleshooting
When the Fan Motor is inoperable or cycling outside of the operational parameters, first verify
the LED for Relay 1 is illuminated, indicating the Board is calling for the Fan Motor to run. If the
unit is in the Freeze Cycle and the LED is not illuminated, the issue may be the board. If it is
Illuminated, check voltage between the Violet and Blue with a meter. Line voltage should be
shown. If inappropriate voltage is shown, verify the Molex connection at the Board and correct
if loose. If there is still no voltage out, replace the Board. If voltage is verified, check contacts of
Fan Cycle Switch for voltage then check contacts which should be closed at pressures above 250
psi. If open in these conditions, jump control. If Fan Motor comes on, issue is Fan Cycling
Control. If the Motor does not come on, check the connection at Motor. If verified, the issue is
the Fan Motor.

EVAPORATOR
58
Evaporator
The nickel‐plated Evaporator Assembly has a copper core to assure good heat transfer. Water is
pumped gently over the Evaporator during the freeze cycle for even ice formation.
Evaporator Operation
The Evaporator should be fully flooded with refrigerant for most of the freeze cycle to ensure
even ice formation. The serpentine on the back of the Evaporator starts at the bottom right
corner of the plate (viewed from the front). The refrigerant lines run horizontally back and forth
to the middle of the plate then rise along the left‐hand side to the top. The line continues to
“serpentine” downward to the middle of the plate and exit the Evaporator.
Troubleshooting
The Evaporator should always have a nickel appearance. Should the Evaporator have a “rust”
color after a thorough cleaning, the plating may have come off and a replacement may be
required. A dull “rainbow shimmer” may indicate an improper cleaner was used on the unit.
Only approved Nickel Safe ice machine cleaner should be used.
An improper ice formation can be caused by a water or refrigeration issue.
A dirty water system can cause poor water flow over the Evaporator resulting in improper ice
formation. See pg. 56 for Cleaning Instructions.
A refrigeration issue such as a low charge or restricted TXV could show on the Evaporator as ice
forming on the bottom of the plate with thin to no ice forming on the top half. Verify refrigerant
pressures on the Technical Specifications chart on pg. 60.
Should the ice slab resist coming off the plate, examine the Evaporator for loss of plating,
pitting, mineral accumulation and/or loose horizontal dividers. Should any of the horizontal
dividers separate from the base, replacement of the Evaporator is recommended.

HIGH TEMP SAFETY
67
High Temp Safety (optional)
The High Temp Safety is a bi‐metal thermostat strapped to the line at the outlet of the Hot Gas
Valve. Should the Hot Gas Valve stick open, and the refrigerant line reach 180° F., the High
Temp Safety would open, dropping power to the Contactor and shut down the Compressor.
When the line temperature drops below 120° F., the contacts of the Safety will close, allowing
power to the Contactor.
Note: 48” units have two high temp safety switches connected in series, should either hot gas
circuit trigger a switch, it will shut down the compressor.
Troubleshooting
Should the Compressor not run with the R2 relay LED illuminated, verify if High Pressure Cutout
is closed and Contactor coil is good. The discharge line from the Hot Gas Valve should be cool to
the touch during a freeze cycle. With a line temperature below 120° F. (confirming hot gas valve
is closed), the contacts in the High Temp Safety should be closed. Disconnect both leads of the
High Temp Safety and check for continuity. If it open with a cool line, the safety will need to be
replaced.
ELEVATION SERIES CIM CUBER
REFRIGERATION SECTION
68
Refrigeration Section
The Refrigeration Section on a CIM Cuber contains the Compressor, Thermostatic Expansion
Valve, Hot Gas Valve and Condenser. Remote systems also utilize a Mixing Valve (LAC), Liquid
Line Solenoid and Receiver. However, this section will vary as we Phase out R-404a and move
to more environmentally friendly refrigerants including R-449a, and R-290 refrigerants.
Refrigeration Section Operation
The Compressor drives the refrigeration system. Ice‐O‐Matic uses a Thermostatic Expansion
Valve to control refrigerant flow through the Evaporator.
Troubleshooting - System
When troubleshooting the refrigeration system, always use stub gauges to limit the amount of
refrigerant lost during connecting and disconnecting.
Always verify the refrigeration systems operating pressures when diagnosing any refrigeration
component. The Compressor should pull within 10% of the RLA when measured 5 minutes into
the Freeze Cycle and greater than 70% of RLA during the Freeze Cycle to be considered efficient.
Thermostatic Expansion Valve
The Thermostatic Expansion Valve meters refrigerant through the Evaporator.
Troubleshooting - Expansion Valve
First verify proper system pressures and charge. Verify the TXV bulb is securely mounted at 7
degrees off vertical (12:30 position) and well insulated. Generally, low suction pressure with a
normal head pressure will show poor ice formation top to bottom on the Evaporator and
indicate a low side restriction such as at the TXV. Should suction run high or not drop, verify bulb
connection to suction line and look for sweating or frosting on the dome of the Compressor
indicating TXV is stuck open.
ELEVATION SERIES CIM CUBERS
GENERAL MAINTENANCE
69
Hot Gas Valve
The Hot Gas Solenoid Valve opens to provide gas to the Evaporator during the Harvest Cycle.
Troubleshooting - Hot Gas Valve
Should the valve not open at the initiation of the Harvest Cycle (R3 LED ON), verify voltage at the
coil of the solenoid. If no voltage is present, verify Molex is properly connected at Board and
Voltage is present at Molex. If Voltage is present at coil, verify resistance through coil. If the coil
shows open, replace the coil. If the coil checks out, place magnetic donut on top of coil. If valve
will not open, replace the Hot Gas Valve body. Should suction pressure run high, check the
temperature of the inlet and outlet line of the Hot Gas Valve. It should be greater than 10‐
degree F. different. If less than 10 degrees F., the Valve is leaking and should be replaced. (See
also pg. 54.)
Liquid Line Solenoid
The Liquid Line Solenoid opens to allow refrigerant to flow from the Receiver on Remote
Systems. It is energized by R1 along with Remote Fan Motors. Diagnosis of Liquid Line Solenoid
is much the same as the Hot Gas Solenoid Valve (see above.)
Mixing Valve
The 220 psig. Mixing Valve (or LAC) Is used to maintain head pressure in low ambient.
Troubleshooting - Mixing Valve
In lower ambient temperatures, the Mixing Valve bypasses the Condenser to maintain head pressure.
During bypass mode, the inlet and outlet lines at the Condenser are at the same temperature. In
warmer ambient conditions, the Mixing Valve directs refrigerant to the Condenser Coil, resulting in
an approximate 20°F temperature difference. A low charge is indicated by hot inlet and outlet lines at
the Condenser and a hot Receiver. It is important to verify the system charge before determining if
the Mixing Valve is faulty.

R-290 Troubleshooting
R‐290 is an A3 refrigerant, which refers to refrigerant grade propane (pure), a substance
that is odorless, highly flammable and displaces air as it is heavier than air. This
refrigerant has been used in the industry for several years. Specific precautions should
be taken when handling R‐290. Since R-290 is flammable, work in an open, well-
ventilated area.
Use appropriate tools to ensure safety.
o Combustible gas leak detector
o Tubing cutters
o Pinch-off tool
o Voltmeter
o Amp meter
o Temperature clamp probes
o Schrader taps
o Combustible gas Warning signs
o Refrigerant scale
o Vacuum pump
o Nitrogen
o R290 Temperature pressure Chart
All of the components work the same. But testing of the refrigeration section will be a little different.
Pressure will not be tested until the last resort as these units are critically charged.
Using a temperature pressure chart you can determine approx. pressure.
Measuring compressor amperage can show workload of the compressor to determine if the charge is
correct, restriction, or compressor performance. High amperage could be indicative of dirty condenser
coils, condenser fan motor, compressor beginning to fail, or low voltage to the compressor.
Low amperage could be a compressor motor weak or failing, low refrigerant charge, restriction, or the
valves in compressor not pumping
Using temperature clamps txv operation, hot gas valve operation, evaporator performance, and
condenser performance can be determined.
Units are sealed no Schrader ports and will need to be resealed after and refrigeration service.

Explanation of Refrigeration System
Understanding Freeze and Harvest Cycles in Ice Machines
The diagram referenced illustrates the flow of refrigerant through an ice machine’s components during both freeze and
harvest cycles. For R‐290 machine trouble shooting
Freeze Cycle
During the freeze cycle, refrigerant circulates from the compressor to the condenser via the discharge line. In the
condenser, heat exchange occurs: hot, high‐pressure gas releases its heat into the air and condenses into a warm, high‐
pressure liquid. This liquid proceeds through the thermal expansion valve (TXV), which meters the flow, resulting in a
cool, low‐pressure liquid. As this refrigerant absorbs heat from the water at the evaporator, it transforms into a cool,
low‐pressure gas, which is then drawn back to the compressor, completing the loop. The temperature and pressure can
be checked at various points —evaporator and condenser inlets and outlets—can be matched with a temperature‐
pressure chart for diagnostic purposes.
ELEVATION SERIES CIM CUBERS
GENERAL MAINTENANCE
72
Harvest Cycle
In the harvest cycle, the hot gas valve opens, redirecting hot, high‐pressure gas directly to the evaporator. This sudden
influx of heat raises the plate temperature above freezing, allowing ice to be released from the plates. At this stage, the
mixture of hot gas and cool liquid from the TXV ensures an efficient harvest. Proper timing is crucial; if the harvest
phase is too prolonged, it can cause overheating or lead to liquid flooding in the compressor, which may damage the
system.
Key Diagnostic and Maintenance Points
• Temperature-pressure charts help estimate system pressures for troubleshooting.
• Compressor amperage readings indicate if the compressor is working properly or if there are issues such as
restrictions, low charge, or failing components.
• Units are critically charged and sealed, lacking Schrader ports, so testing pressures is a last resort.
• Routine cleaning and maintenance, especially of the condenser and ice-making sections, are vital for reliable
operation and to maintain warranty coverage.
These diagrams help the technicians to assess performance and diagnose problems by following the refrigerant’s
path and monitoring system temperatures and pressures. Understanding the freeze and harvest cycles enables
efficient troubleshooting and ensures the longevity of the ice machine.

CLEANING/SANITIZING PROCEDURES
74
Cleaning and Sanitizing
Cleaning Instruction for Ice-O-Matic CIM Series Ice Machines
Note: Proper cleaning of an ice machine requires two parts: descaling and sanitizing.
Descaling should be scheduled at a minimum of twice per year but no more than once per month.
Descaling dissolves the mineral deposits on the evaporator and other surfaces. It removes scale, calcium, lime
scale and other mineral buildup. Ice-O-Matic requires a “nickel-safe” cleaner such as Nu-Calgon Nickel-Safe Ice
Machine Cleaner or equivalent diluted per manufacturer’s instructions.
Sanitizing should be performed after each descaling but no more than once per month.
Sanitizing disinfects the machine and removes microbial growth including mold and slime. Ice-O-Matic requires
a “nickel-safe” sanitizer such as Nu-Calgon IMS-III or equivalent diluted per manufacturer’s instructions.
Please refer to www.iceomatic.com for approved chemical formulations and proper pH balance.
CAUTION: Do not mix cleaner (descaler) and sanitizer together.
Eye protection is recommended when handling descaler or sanitizer.
Wear protective rubber gloves when handling descaler or sanitizer.
Note: Electrical power will be ON when performing the following cleaning instructions.
1.
Remove all ice from storage means to prevent any contamination of ice in storage.
2.

Cabinet Care
Chemicals for Descaling and Sanitizing
It is important to use solutions that do not harm the ice machine. Never use cleaning or sanitizing solutions that
contain Nitric Acid, Sulfuric Acid, Hydrochloric Acid, Carbolic Acid, Acetic Acid, diluted Acetic Acid or non-
food-grade vinegar (concentration of acetic acid greater that 6% and does not contain enzymes created in
processing) or any chlorine-based solution such as bleach, chlorine dioxide or any type of salts such as
potassium chloride (potassium salts) or sodium chloride. Check the label or the manufacturer’s Material Safety
Data Sheet (MSDS) to be sure. These chemicals can attack the surface of the evaporator as well as other metal
components causing corrosion and flaking. Using the incorrect cleaner or sanitizer will void the warranty
of the unit
Please refer to www.iceomatic.com for approved chemical formulations and proper pH balance.
Cleaning Stainless Steel and Aluminum
Commercial grades of stainless steel and aluminum are susceptible to rusting or corrosion if not properly
maintained. It is important that you properly care for the stainless steel and aluminum surfaces of your ice
machine and bin to avoid the possibility of rust or corrosion.
Use the following recommended guidelines for keeping your machine looking like new:
1.
Clean the stainless steel and aluminum thoroughly once a week. Clean frequently to avoid
the build-up of hard, stubborn stains. Hard water stains left to sit can weaken the metals
corrosion resistance and lead to rust or corrosion. Use a nonabrasive cloth or sponge,
working with, not across, the grain.
2.
Do not use abrasive tools to clean the metal surface. Do not use steel wool, abrasive sponge
pads, wire brushes or scrapers to clean the metal.
3.
Do not use cleaners that use chlorine or chlorides. Do not use chlorine bleach products to
clean the metal surfaces. Chlorides break down the metals protective layer.
4.
Rinse with clean water. If chlorinated cleansers are used, you must thoroughly rinse the sur-
face with clean water and wipe dry immediately.
5.
Use the right cleaning agent. The table below lists the recommended cleaning agents for com-
mon metal cleaning problems.
