Installation Guidelines

For proper operation of the Ice-O-Matic® ice machine, the following installation guidelines must be followed.

Failure to do so may result in loss of production capacity, premature part failures, and may void all warranties.

Ambient Operating Air Temperatures: (Including Remote Condenser, See Below)

Minimum Operating Temperature: 50°F (10°C)

Maximum Operating Temperature 100°F (38°C)

Remote Condenser Maximum Operating Temperature 120°F (49°C)

Note: Ice-O-Matic® ice makers and dispensers are not approved for outdoor installation.

Incoming Water Supply

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)

Maximum incoming water pressure: 80 psi (4.1 bar)

Note: If water pressure exceeds 80 psi a water pressure regulator must be installed.

Note: It is not recommended to connect a water softener because the ice may be more wet and slushy

than desired. Water Softeners add salinity, raising the freeze point resulting in “softer” ice. This

results in lower ice production.

Drains

All drain lines must be installed per local codes. Flexible tubing is not recommended. Route bin drain, vented

float overflow drain and water condenser drain individually to a floor drain. The use of condensate pumps for

draining water is not recommended by Ice-O-Matic®. Ice-O-Matic® assumes no responsibility for improperly

installed equipment.

Water Filtration

A water filter system should be installed with the ice machine.

Clearance Requirements

Self-contained air cooled ice machines must have a minimum of 6 inches (15cm) of clearance at the rear and

sides of the ice machine for proper air circulation.

Stacking

Ice-O-Matic® GEM-MFI Series ice machines are not designed to be stacked.

Dispenser Application

The GEM ice machine is approved for specific dispenser applications, reference page 5.

The MFI Series is not approved for dispenser applications.

Electrical Specifications

Refer to the serial plate at the rear of the ice machine to make sure proper voltage and circuit breaker size

have been supplied. Make sure the machine is on a dedicated circuit. The GEM-MFI Series are not supplied

with an electrical power cord and will need to be installed and wired per local electrical codes.

Adjustments

Level the machine within 1/8 inch in all directions. Adjust the cabinet or bin legs as required.

Check the bin control for proper operation.

Check the water level in the reservoir for proper adjustment.

Check the water regulating valve adjustment if water cooled

All the dispensers have automatic agitation to keep the ice from clumping. If agitation is too frequent, the Pearl

Ice will be damaged and will become difficult to dispense. The Ice-O-Matic® and Cornelius® dispensers need to

be set to 2 seconds on every 3 hours and the Lancer needs to be set to 4 seconds on, 150 seconds off.

The Ice-O-Matic® and most Cornelius® dispensers also have a restrictor plate at the outlet of the hopper. When

used, that plate should be adjusted to be 1.5 inch open to limit the speed of the Pearl Ice flows out during

dispensing.

For the Installer (Location)

Ice-O-Matic® ice machines are designed to be installed indoors in a controlled environment. Install the ice

machine in a location where it has enough space around it to be accessible for service. A minimum of 6 inches

must be allowed at the back for air circulation on air cooled models. Try to avoid hot, dirty and crowded

locations. Be sure that the location of the machine is within the environmental limitations.

Storage Bin:

Remove the bin packaging. Tip the storage bin on its back, using parts of the packaging to protect the exterior

finish. Remove the skid and install the legs into the threaded holes in the bottom of the bin. Turn the leg

levelers all the way in preparation for leveling later. Return the bin to the upright position.

Note: Do not push the bin into position, but lift it there. Pushing a bin, especially one with ice in it, can cause

damage to the bin legs and mounts.

Install the appropriate bin top according to the instructions provided with the bin top.

Ice machine:

The ice machine is heavy, so the use of a mechanical lift is recommended for lifting the machine high enough

to install on top of the bin. After the unit is placed on the bin, line it up so it is even with the back side. Secure

the ice machine to the bin with the hardware provided with the ice machine. Remove the front panel and

remove any shipping blocks or packaging material.

Proper functioning of the bin door requires the bin door, when it is opened, to be in a stable position. If the ice

machine is too far forward on the bin, the opened door may not be stable, resulting in an unexpected closing of

the bin door.

If the ice machine is to be mounted on a bin or dispenser other than an Ice-O-Matic®, refer to the

manufacturer’s instructions for machine mounting. Ice-O-Matic® will not be responsible for damage or injury

that results from unexpected closing of the bin door as a result of the ice machine being too far forward on the

bin.

Water Limitations:

An ice machine is a food manufacturing plant: it takes a raw material, water and transforms it into a food

product, ice. The purity of the water is very important in obtaining pure ice and maximizing product life. This

section is not intended as a complete resource for water related questions, but it does offer these general

recommendations:

●Check with a water treatment specialist for a water test and recommendations regarding water filters and

treatment.

●In most cases, the water used to make ice should be filtered or treated, depending upon the water.

There is no one type of water filter that is effective in all situations. That is why a water test in important.

RO Water Limitations:

Water conductivity must be no less that 35 microSiemens/cm.

Notice:

Ice-O-Matic® ice machines are designed and manufactured with the highest regard for safety and performance

and meet or exceed the standards of UL, NSF and CUL.

Ice-O-Matic® assumes no liability or responsibility of any kind for products manufactured by Ice-O-Matic® that

have been altered in any way, including the use of any part and/or other components not specifically approved

by Ice-O-Matic®.

Ice-O-Matic® reserves the right to make design changes and/or improvements at anytime. Specifications and

design are subject to change without notice.

Allow 6 inches of Clearance

for Air Circulation

Allow 6 inches of Clearance

for Air Circulation

Two Units on One Bin

A proper installation locates the

ice machine indoors, but in a

place where the heat and noise it

produces are not objectionable.

Air cooled machines discharge

hot air out the back and must

have a minimum of 6 inches of

clearance behind the ice

machine.

Space for maintenance access is

also important. If two units are

placed side by side on a bin, side

access becomes even more

important.

9

Remote Condenser Installation

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:

● Maximum rise from the ice machine to the remote condenser is 35 physical feet.

● Maximum drop from the ice machine to the remote condenser is 15 physical feet.

● Physical line set maximum length is 100 feet.

● Calculated line set length maximum is 150 feet.

Calculation Formula

● Drop = dd x 6.6 (dd= distance in feet)

● Rise = rd x 1.7 (rd = distance in feet)

● Horizonal Run = hd x 1 (hd = distance in feet)

● Calculation: Drop(s) + Rise(s) + Horizontal Run = dd+rd+hd=Calculated Line Length

Configurations that do NOT meet these requirements must receive written authorization from

Ice-O-Matic®. This includes multipass or rack system remote condensers.

Do NOT:

● Route a line set that rises, then falls, then rises.

● Route a line set that falls, then rises, then falls.

Calculation Example 1:

The remote condenser is to be located 5 feet below the ice machine and then 20 feet away horizontally.

(5 feet x 6.6=33 feet) + (20 feet) = 53 feet. This location would be acceptable.

Calculation Example 2: The remote condenser is to be located 35 feet above the ice machine and then 100

feet away horizontally. (35 feet x 1.7=59.5 feet) + (100 feet) = 159.5 feet. 159.5 feet is greater than the 150

maximum is NOT acceptable.

10

Remote Condenser Location

Limited to a 25 foot or a 40 foot length of precharged refrigerant tubing connecting the ice machine to the

remote condenser. The remote condenser must be above or level with the ice machine. Select the best

available location, protecting the remote condenser from extremes of dirt, dust and sun. Meet all applicable

building codes. Usually the services of a licensed electrician are required.

Roof Attachment

1. 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.

2. Have an electrician connect the remote condenser fan motor to the ice machine, using the junction box at

the back of the ice machine.

Precharged Line Set Routing

CAUTION: Do not connect the precharged

tubing until all routing and forming of the

tubing is complete. See the coupling

instructions for connecting information.

1. Each set of preharged tubing refrigerant lines

consists of a 3/8 diameter liquid line and a 1/2

inch diameter discharge line. Both ends of

each line have quick connect couplings, one

end has a Schrader valve connection, that end

goes to the condenser.

Note: The openings in the building ceiling or

wall, listed in the next step, are the minimum

sizes recommended for passing the refrigerant

lines through.

2. Have the roofing contractor cut a minimum

hole for the refrigerant lines of 1.750 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.

3. Route the refrigerant lines through the roof

opening. Follow straight line routing whenever

possible. Any excess tubing MUST remain

within the building.

4. Spiral the excess length of precharged tubing

inside the building. Use a horizontal spiral

(does not need to be as tight as illustrated) to

avoid any traps in the lines.

5. Have the roofing contractor seal the holes in

the roof per local codes.

CAUTION: The couplings on the sets of

precharged lines are self sealing when

installed properly. Carefully follow the instructions:

Coupling Instructions

Initial Connections:

1. Remove the protector caps and plugs. Wipe the seats and threaded surfaces with a clean cloth to be

certain that no foreign matter remains on them.

2. Lubricate the inside of the couplings, especially the O-Rings with refrigerant oil.

3. Position the fittings on the correct connections on the remote condenser

and ice machine.

●The 1/2 inch discharge line (Schrader valve end) goes to the remote

condenser fitting marked “Discharge Line”

●The 3/8 inch liquid line (Schrader valve end) goes to the remote

condenser fitting marked “Liquid Line”.

●The 1/2 inch discharge line goes to the ice machine fitting marked

“Discharge Line”.

●The 3/8 inch liquid line goes to the ice machine fitting marked “Liquid

Line”.

Final Connections

4a. Begin by tightening the couplings together by hand. Continue to turn the swivel nuts by hand until it is

certain that the threads are properly engaged.

4b. Using two wrenches, one to rotate the swivel nut and one to hold the tubing, tighten each coupling.

It is CRITICAL that ONLY the NUT on the precharged tube be turned or

the diaphragms will be torn loose by the piercing knives and be loose in

the refrigeration system causing severe operational problems.

Note: As the coupling is tightened, the diaphragms in the quick connect

couplings will begin to be pierced. As that happens, there will be

increased resistance to tightening the swivel nut.

4c. Continue tightening the swivel until it bottoms out or a very definite

increase in resistance is felt (no threads should be showing). Do NOT

over tighten.

5. Using a marker or pen, mark a line lengthwise from the coupling union nut

to the bulkhead. Then tighten the coupling and additional 1/4 turn. As

the nut turns, the line will show when the 1/4 turn is made.

6. After all connections are made, and after the king valve has been opened

(do not open at this time) check the couplings for leaks.

For the Plumber

Water Inlet:

●Air Cooled Models The recommended water supply is clean, cold water. Use 3/8 inch O.D. copper tubing,

connect to the 3/8 inch FPT at the back of the cabinet. Install a hand valve near the machine to control the

water supply.

●Water Cooled Models A separate 3/8 inch O.D. copper line is recommended, with a separate hand valve to

control it. Connect to the 3/8 inch FPT condenser inlet at the back of the cabinet. The water pressure to all

lines must always be above 20 psig, and below 80 psig.

●Water Treatment In most areas, a water filter of some type will be useful. In areas where the water is highly

concentrated with minerals, the water should be tested by a water treatment specialist, and the

recommendations of the specialist regarding filtration and/or treatment should be followed.

Drains

●Air Cooled Models Connect a rigid drain tube to the ¾ FPT drain fitting at the back of the cabinet. The drain is

a gravity type, and a ¼ inch per foot fall is the minimum acceptable pitch for the drain. There should be a vent

at the highest point of the drain line, and the ideal drain receptacle would be a trapped and vented floor drain.

Use only ¾ inch rigid tubing.

●Water Cooled Models Connect a separate drain line to the ½ inch condenser drain connection at the back of

the cabinet. Do not vent this drain.

●Storage Bin Connect a separate gravity type drain line to the ice storage bin drain. Vent this drain if there is a

long horizontal run from the bin to the floor drain. Insulation of this drain line is recommended.

Cleaning

ICE Machine and/or Bin/Dispenser Cleaning and Sanitizing Instructions

Cleaning should be scheduled at a minimum of twice per year.

Sanitizing should be performed after each cleaning or more frequently as required.

Note: Electrical power will be ON when performing the following cleaning instructions.

Caution: Eye protection is recommended when handling descaler or sanitizer.

Wear protective rubber gloves when handling descaler or sanitizer.

The cleaning and sanitizing of any commercial ice machine are important procedures all operators need to

have in their preventive maintenance protocol. While similar, these two procedures are uniquely different and

accomplish different things. Cleaning or de-liming, dissolves the mineral deposits on the evaporator and

removes scale, calcium and other chemical buildup. Sanitizing disinfects the machine and removes microbial

growth including mold and slime.

In either case, 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 than 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. 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 is 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.

Cleaning/Descaling

Prior to Cleaning the ice machine and/or Bin/Dispenser, perform the following:

1. Remove the ice machine front panel.

2. Turn the machine “OFF” at the ON/OFF selector switch.

3. Remove all ice in the storage bin. (Required for cleaning and/or sanitizing)

Cleaning Instructions-Ice Machine

1. Remove the cover from the water reservoir and block up the float.

2. Drain the water reservoir and freezer assembly using the drain tube attached to the freezer water inlet.

Return the drain tube to its normal position and replace the end cap.

3. Add recommended amount of ice machine cleaner (diluted per manufacturer’s instructions) to the water

trough. (Reference cleaner Manufacturer’s instructions on the package)

4. Slowly pour the cleaning solution into the water reservoir until full. Wait 15 minutes, then switch the

ON/OFF switch to the ON position.

5. As the ice machine begins to use water from the reservoir, continue to add more cleaning solution to

maintain a full reservoir.

6. After all of the cleaning solution has been added to the reservoir, and the reservoir is nearly empty, switch

the ON/OFF switch to the OFF position.

7. Drain the water reservoir and freezing assembly using the drain tube attached to the to the freezer water

inlet. Return the drain tube to its normal position and replace the drain plug end cap. Wash and rinse the

water reservoir.

8. Sanitizing the Ice Machine is required after cleaning per Sanitizing Instructions

23

Cleaning Instructions-Storage Bin/ Dispenser

1. Open the bin door and remove all of the ice in the storage bin, store the ice in a clean container for reuse or

discard.

2. Add recommended amount of ice machine cleaner (diluted per manufacturer’s instructions) (Reference

cleaner Manufacturer’s instructions on the package)

3. Thoroughly wash all surfaces within the bin, this includes the bin door, bin walls, window track and snout

area with cleaner and water. Note: An extended handle soft bristle brush may be required.

4. Allow the mineral deposits to absorb the cleaner for approximately 15 minutes to remove and loosen the

mineral deposits. Note: This includes the bin drain.

5. Rinse thoroughly with water. Note: Repeat Steps 3, 4 and 5 as required.

6. Sanitizing the Storage Bin/Dispenser is required after cleaning per Sanitizing Instructions

24

Sanitizing

Prior to Sanitizing the ice machine and/or Bin/Dispenser, perform the following:

1. Remove the ice machine front panel and top panel.

2. Turn the machine “OFF” at the ON/OFF selector switch.

3. Remove all ice in the storage bin. (Required for cleaning and/or sanitizing)

Sanitizing Instructions-Ice Machine

1. Use an EPA approved food equipment sanitizer at the solution mix recommended by the sanitizer

manufacturer.

2. Slowly pour the sanitizer solution into the water reservoir until full. Wait 15 minutes, then switch the ON/OFF

switch to the ON position.

3. As the ice machine begins to use water from the reservoir, continue to add more sanitizing solution to

maintain a full reservoir.

4. After all of the sanitizing solution has been added to the reservoir, and the reservoir is nearly empty, switch

the ON/OFF switch to the “OFF” position.

5. Drain the water reservoir and freezing assembly using the drain tube attached to the to the freezer water

inlet. Return the drain tube to its normal position and replace the drain plug end cap. Wash and rinse the

water reservoir. During this time, wipe down all other ice machine splash areas. Inspect to insure that water

transport system components are in the correct position.

6. Place the ON/OFF switch to the “ON” position and replace the front panel.

7. Continue ice making for at least 15 minutes to flush out any cleaning or sanitizing solution.

8. Remove and discard all ice in the storage bin. DO NOT USE any ice produced from the cleaning

solution.

Condenser Cleaning

The condenser may appear to be clean on the

surface, but it can still be clogged internally.

Check with a flashlight from the front to see if

light can be seen through the condenser fins.

The condenser coil must be kept clean. The

condenser can be cleaned with compressed air

or by using a brush with soft bristles..

If a brush is used, brush in the direction of the

fins taking care not to bend or distort the fins.

If the condenser fins are bent or distorted, this will restrict the airflow through the condenser and the fins will

need to be straightened with a fin comb.

When cleaning the Condenser, check the fan blade for cleanliness and for balance. Balance is checked by

spinning the blade by hand and looking for any wobble. Pull on the shaft in several directions to check the

bearings of the motor.

The fins of the remote condenser require periodic cleaning.

At 6 month intervals the fins on the inlet side of the condenser (bottom as shown) should be brushed free of

dust and dirt

Brush in the direction of the fins as noted by the arrows.

Additionally look through the fins, using a flashlight if required, to insure there is no other blockage obstructing

air flow between the fins.

If the air flow appears to be blocked, blow out the condenser using compressed air.

Caution: Disconnect electrical power before servicing this equipment.

Caution: Protective eye wear and gloves should be worn when cleaning the condenser.

26

Clean the air cooled condenser:

Air flow on this model is from front to back, so the inside of the ice machine will have to be available to clean

the air cooled condenser. Use a vacuum cleaner or coil cleaner if needed. DO NOT use a wire brush.

● Disconnect electrical power, and remove the air filter if applicable. The filter may be cleaned or replaced.

● Clean the condenser: the condenser may appear to be clean on the surface, but it can still be clogged

internally. Check with a flashlight from the front to see if light can be seen through the condenser fins.

GEM0956 (For Reference)
