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 by Ice-O-Matic. Ice-O-Matic assumes no responsibility for improperly installed equipment.

Note: The purge drain fitting is plastic; DO NOT apply heat to the purge drain area; DO NOT overtighten.

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, top, and

sides of the ice machine for proper air circulation. Exceptions such as Top Air Discharge machines will be listed in the

machine specification sections.

Stacking

Ice-O-Matic does not endorse stacking ice machines.

Dispenser Application

A thermostatic bin control kit should be installed if the ICE Series ice machine is placed on a dispenser. A bin top may

or may not be required. (Exception is the CD400 Series Dispenser)

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. European installations require that the electrical supply

fixed wiring must be provided with a disconnect means having a separation of at least 3mm in all poles. The ice

machines are provided without an electrical cord set and are designed and agency approved to be permanently

connected.

The 115 volt Undercounter series ice makers are supplied with an electrical cord, all other ice makers will

need to be installed and wired per local electrical codes. A GFI outlet is not approved.

Caution: Electrical connection must be made or a cord installed by a qualified electrician or there is danger of an

electrical fire.

Adjustments

Page 3

Remove the bin carton and tip the bin on its back to remove the skid and attach the bin legs.

Secure the machine on top of the bin or dispenser.

Attach the ice machine to the bin with the mounting straps provided with the bin or dispenser. Insure that the back of

the ice machine is flush with the back of the bin. 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

manufacturers 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.

Important!

A water filtration system should be installed with all ice machines. Check the filter manufacturer's instructions for

proper installation.

All water supply lines must be installed per local codes.

Use 1/4 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

float can “T” off from the condenser line using 1/4 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.

All drain lines must be installed per local codes. The

purge drain should be a minimum of 5/8 inch O.D. tubing.

The condenser drain on water cooled units should be 3/8

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. Cold water drains should be insulated to

prevent condensation from forming.

Warning!

Do not apply heat directly to the back of bin as

damage may occur to plastic parts.

Do not over tighten the purge drain fitting as damage

may occur to plastic parts.

Connect power supply to the terminal block in the control

box or at the rear junction box if equipped.

Ensure the machine is level within 1/8 inch in all

directions.

Remote Condenser Installation

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 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:

● 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 75 feet.

● Calculated line set length maximum is 100 feet.

● Ambient operating temperatures: -20°F (-28.9°C) to 120°F (48.9°C)

Calculation Formula

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

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

● Horizontal 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.

Remote Condenser Location:

Limited to a 25, 40, 45, 60 or a 75 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 wires 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 precharged 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 which 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 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.

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 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 in the VRC manual.

ICE Series Remote Condenser Guidelines

ICE Series How the ICE Machine Works

Page 15

How the ICE Machine Works

A general description of how the ICE Series cubers works is given below. With the ICE/OFF/WASH switch in the ICE

position, the compressor, water pump and condenser fan motor (when applicable) will energize starting the freeze

cycle.

During the freeze cycle, water is circulated over the evaporator(s) where the ice cubes are formed. When the suction

pressure has pulled down to the proper cut-in pressure of the timer initiate (pressure control), the contacts will close

and energize the time delay module (timer). At this time, the cubes will be close to completion.

The remaining portion of the freeze cycle is determined by the timer setting. The timer is pre-set at the factory to

achieve the proper ice bridge thickness but may need to be adjusted upon initial start-up, see Page 14 for timer

adjustment.

The factory initial timer settings are 64 and 128 for the Half Cube and 128 and 256 for a Full Cube.

Once the amount of time on the timer has passed, the control relay will be energized and the machine will enter

harvest. Power is now supplied to the water purge valve, hot gas valve, and the harvest motor.

The water purge valve opens, and allows the water pump to purge the water remaining in the water trough, removing

impurities and sediment. This allows the machine to produce clear ice cubes and keep mineral build up at a minimum.

The hot gas solenoid opens allowing hot gas to go directly to the evaporator, heating the evaporator and breaking the

bond between the evaporator and the ice slab.

Note: The operation of the Hot Gas valve and Water Pump vary by model number, reference the wiring

diagram on the specific model number for operation sequence.

The harvest assist motor, which is also energized during harvest, turns a slip clutch, which pushes a probe against the

back of the ice slab. Once the evaporator has reached approximately 40F (4.5F) in temperature, the slip clutch

overcomes the bonding of the ice to the evaporator and pushes the slab of ice off of the evaporator and into the

storage bin.

The clutch also actuates a switch that rides on the outer edge of the clutch. When the clutch completes one

revolution, the switch is tripped and the machine enters the next freeze cycle.

Note: Units produced from July of 2015 utilize an improved drive motor which eliminated the clutch assembly.

When ice drops into a full bin during harvest, the splash curtain is held open which activates a bin switch shutting the

machine off. When ice is removed from the bin, the splash curtain will close and the machine will come back on.

Note: The ICEU150, 220, 225, 226, ICEU300 and 305 do not have a splash curtain. These models utilize a

thermostatic bin control in place of a mechanical bin switch.

ICE Series Start-Up Procedure

Page 16

Start-Up Procedure

Before starting the machine, make sure the machine is level within 1/8 inch in all directions, the bin or dispenser leg

height can be adjusted by rotating the leg foot.

Check the water level in the water trough. It should be approximately ½ inch above the top of the water pump impeller

housing. The water level can be adjusted by bending the float arm.

Move the ICE-OFF-WASH switch to the ICE position. The switch is located in the control box. Remove the ice machine

front panel or remove the lower grill on the under counter models to access the control box.

Check for proper water flow over the evaporator(s). There should be an even flow of water over the evaporator(s).

Check the water regulating valve (water cooled machine) for proper adjustment by measuring the discharge pressure

which should be adjusted to maintain 250 psi (17.01 bar / 1.723 MPa). Adjust the water regulating valve as required.

Water exiting the condenser should be between 100°F (38°C) and 110°F (43°C).

As ice begins to form on the evaporators, check the freeze pattern of the ice. Ice should form evenly across the

evaporator. Models ICE0800, 1000, 1800 and 2100 machines will have a slight variance from the top to the bottom of

the evaporator(s).



As a reference, when ice drops off the evaporator(s) during harvest, check the bridge thickness of the ice slab. The

bridge should be approximately 3/16 of an inch on Undercounter, ICE0250 and ICE0305 units. The bridge should be

approximately 1/8 of an inch on all other units. If the batch weight or bridge thickness is incorrect, the timer will need to

be adjusted.

Both the Ice Batch Weight and Bridge Thickness are controlled by the freeze timer located in the control box. To check

the timer setting, add the seconds of each dipswitch turned to the “ON” position. The number beside the each

dipswitch represents seconds. To increase the Batch Weight and bridge thickness, increase the timer setting. To

decrease the Batch Weight and bridge thickness, decrease the timer setting. The freeze timer can be adjusted by

sliding one or more switches to either the “ON” or “OFF” position to obtain the desired setting.

ICE Series Start-Up Procedure

Page 17

Bin Control Operation

The bin control is used to shut the machine off when the bin fills with ice. The bin control must be checked upon

installation or initial start-up and when performing maintenance. Adjustments are not covered under warranty.

There is one bin switch for each evaporator. The actuator arm of the bin switch comes in contact with the splash

curtain. When the bin is full of ice, the splash curtain is held open when ice drops off of the evaporator. This releases

the pressure of the bin switch actuator arm allowing the switch to open.

Single evaporator machines: (Including the ICE1506R) If the bin switch opens during freeze or the first part of

harvest, relay 2 bypasses the bin switch and the machine will continue running. If the bin switch is opened during

harvest when the cam switch is lifted onto the high part of the cam, the machine will shut off. When the bin switch

closes again, the machine will restart.

Dual evaporator machines: If either bin switch opens during the freeze cycle, the machine will shut off. Relay 1 and

relay 2 will bypass the bin switches during defrost. If either bin switch is open when the machine returns to the freeze

cycle, the machine will shut off.

Undercounter machines: A thermostatic bin control is used on the undercounter

models. The bin thermostat is located in the control box with a capillary tube,

which is in a brass thermo-well mounted to the right side of the water trough.

When ice comes in contact with the capillary tube thermo-well, the bin thermostat

opens and the machine will shut off.

Bin Control Adjustment

All Models (Except Undercounter Models): Check the bin switch for proper

adjustment by swinging the bottom of the curtain away from the evaporator.

Slowly bring the curtain towards the evaporator. The switch should close when

the bottom edge of the curtain is even with the outer edge of the water trough.

Adjust the switch by loosening the nuts that hold the switch in place. Move the

switch to the proper position and retighten the nuts. Recheck the adjustment.

Adjustments are not covered under warranty.

Undercounter Models and ICE1506R

The Bin Thermostat used on these Self Contained Ice Cuber Machines is a

sensitive device influenced by ambient conditions including altitude and

temperature. The machine is set up to operate properly at the factory for 70°F at

sea level. If your ice machine shuts off early, bin half full, or doesn’t shut off, bin

overflowing, please follow these instructions to set the bin thermostat.

1. These instructions are best followed on a full ice bin with at least 3 inches

of ice resting against the brass thermal well. The machine must be

running to perform this adjustment; follow step two if the machine is off.

2. Turn the thermostat adjustment screw clockwise until it stops; this is the

max cold setting and will prevent the machine from shutting off.

3. Hold a minimum of 3 inches of ice against the middle of the brass thermal

well for 3-4 minutes. It is imperative that enough ice be used for the

prescribed time to properly cool the

thermostat.

4. Slowly turn the adjustment screw counter-

clockwise until the machine shuts off. If

the screw is turned too quickly, the

thermostat could be set to too warm a

temperature. Turn slowly.

5. Remove the ice from the well and warm

the brass with your hand; the machine

should turn back on.

The ice machine is now set for ambient

conditions. If the ice machine location

experiences significant changes in ambient

temperatures, this procedure will need to be

followed again. Adjustments are not covered

under warranty.

pressure which should be adjusted to maintain 250 psi (17.01 bar / 1.723 MPa). Adjust the water regulating valve

as required. Water exiting the condenser should be between 100°F (38°C) and 110°F (43°C).

8. Check all electrical connections.

9. Oil the fan motor if the motor has an oil fitting. (Self contained air-cooled models only)

10. Check the water filter (if applicable) and replace if dirty or restricted.

11. Inspect the evaporator water distribution tube to insure even distribution of water across the face of the evaporator.

ICE Series Cleaning/Sanitizing Procedures

Page 19

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.

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 mineral 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.

Common Questions

•Ice-O-Matic Ice Machine/Bin Cleaning

Cleaning or de-liming an ice machine refers to the process of removing mineral buildup and scale from the evaporator

and other components. Ice-O-Matic recommends cleaning the ice machine at least every 6 months. More frequent

cleaning may be needed depending on water quality and filtration system used. It is the responsibility of the operator to

determine the optimal frequency for their particular environment. Cleaning will not remove microbial, mold, or slime.

The machine should always be sanitized after cleaning.

Ice-O-Matic recommends a “nickel-safe” cleaner such as Nu-Calgon or equivalent. Typically the chemical composition

is as follows:

 Water 53% to 82%

 Phosphoric Acid 15% to 40%

 Citric Acid 3% to 7%

Ice-O-Matic recommends cleaning be done by a trained technician and that they follow detailed steps as prescribed in

the Technical Service Manual.

Most cleaners list in their instructions an ounces to a gallon mixture for proper level of solution. Pouring undiluted

cleaner directly into the water trough may not give proper dilution level. Ice-O-Matic recommends mixing in a plastic

container before pouring into trough.

•Ice-O-Matic Ice Machine/Bin/Dispenser Sanitizing

Ice-O-Matic recommends sanitizing or disinfecting an ice maker a minimum of every six months. More frequent

sanitizing may be needed if the machine is in a high yeast environment or if RO water is being used. It is the

responsibility of the operator to determine the optimal frequency for their particular environment.

Ice-O-Matic recommends an EPA approved sanitizer such as Nu-Calgon IMS-II or equivalent. Sanitizing is a simple

matter of running the EPA approved sanitizer through the ice machine/bin/dispenser and wiping down surfaces with

the sanitizer.

If being done at the same time as the cleaning process, sanitizing must be done after the cleaning process. Follow the

process as prescribed in the Owner’s Manual.

Note: this process requires the ice be removed from the bin.

Ice Machine Cleaner contains acids.

KEEP OUT OF THE REACH OF CHILDREN

Refer to ice machine cleaner manufactures emergency

instructions on container label.

Cleaning Stainless Steel and Aluminum

Commercial grades of stainless steel and aluminum are susceptible to rusting and 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 build-up of hard,

stubborn stains. Also, 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. Don't 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. Don't 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 surface with clean water

and wipe dry immediately.

5. Use the right cleaning agent. The table below lists the recommended cleaning agents for common metal cleaning

problems:

Cleaning Activity Cleaning Agent Method of Application

Routine cleaning Mild dish Soap, Ammonia, Glass Apply with a clean cloth

Cleaner, or mild detergent with water. or sponge. Rinse with

Household Kitchen clean water and wipe dry.

Cleaning chemicals approved
