INSTALLATION GUIDELINES
Installation Guidelines
Water Filtration/Treatment
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.
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
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.
Ambient Operating Temperature
Drains
Minimum operating temperature:
50°F (10°C)
Maximum operating temperature:
100°F (38°C) (60 Hz.), 110°F (43°C) (50 Hz.).
Note: Ice-O-Matic ice-makers and dispensers are not
approved for outdoor installation
Incoming Water Supply
(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)
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.
Note: The Purge Drain Fitting is plastic: DO
NOT apply heat to purge drain area; DO NOT
over-tighten drain connection.
The purge drain should be a minimum of 3/4 inch
O.D. tubing. 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.
Cold water drains should be insulated to prevent
condensation from forming.
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.

ELEVATION SERIES CIM CUBERS
INSTALLATION GUIDELINES
Clearance Requirements
Electrical Specifications
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.
Appropriate space should be allowed for proper
serviceability of the machine. Excess time to gain
access for serviceability is not covered under
warranty.
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.
Stacking
Ice-O-Matic does not endorse stacking ice
machines.
Dispenser Application
A thermostatic bin control kit should be installed if
the CIM Cube ice machine is placed on a
dispenser. A bin top may or may not be required
and should be secured to the dispenser.
Units are not approved for GFI outlets.
Caution: Electrical connection must be made or a cord
installed by a qualified electrician or there is danger of
an electrical fire.
Adjustments
Level the machine within 1/8 inch in all directions.
Check the water in the Water Sump for proper
level.
Check the ice bridge for proper thickness and
adjust on Float Switch Housing Assembly as
needed.
Check the Water Regulating Valve adjustment if
water cooled.
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 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.

REMOTE CONDENSER GUIDELINES
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:
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 10 physical feet.
Physical line set maximum length is 75 ft.
Calculated line set length maximum is 100
ft.
Ambient operating temperatures:
-20°F (-28.9°C) to 120°F (48.9°C)
Calculation Formula
Drop = dd x 6.6
(dd = drop distance (ft.))
Rise = rd x 1.7
(rd = rise distance (ft.))
Horizontal Run = hd
(hd = horizontal distance (ft.))
Calculated Line Length = Drop + Rise + Horizontal Run
Configurations that do NOT meet these
requirements must receive written authorization
from Ice-O-Matic. This includes multi-pass or rack
system remote condensers.
DO NOT: Route a line set that rises, then falls, then
rises or a line set that falls, then rises, then falls.
Remote Condenser Location
Pre-charged line sets are available in 25, 40, 45, 60
or 75 foot length 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.
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.
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.
Note: the openings in the building or ceiling or wall,
listed in the next step, are the minimum sizes
recommended for passing the refrigerant lines through.
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.
4
ELEVATION SERIES CIM CUBERS
Route the refrigerant lines through the roof
opening. Follow straight line routing whenever
possible. Any excess tubing MUST remain inside
the building. Spiral the excess length of precharged tubing inside the building. Use a
horizontal spiral to avoid any traps in the lines.
Have the roofing contractor seal the holes in the
roof per local codes.
REMOTE CONDENSER GUIDELINES
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.
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 next page to calculate the
maximum 100 ft. line set run. Maximum actual line set run is limited to 100 ft. Add 1/4 oz. of refrigerant
for each actual foot from 75 to 100 ft. actual line set run.

Adjustment Switch Block
Three 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 5 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 come with the kit, Switch 2 needs to be moved to the ON position to tell the program to read the Bin Thermostat. The LED beside the Bin Stat Connection will then illuminate.
The Switch 3 on the block is for the Cleaning Needed Reminder. When in the OFF position, the
default setting for the 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 hard
water location to help with production levels.
12V DC Molex 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 Configuration 1 and both Fill Configuration LED’s are not used as of the printing of this manual.
Thermistor Molex
The Thermistor is used to guage 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 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.

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 production 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 are closed and will turn OFF
when the contacts are open. The Thermistor is used to measure the temperature of the water in

the Sump during the Freeze Cycle. During the first 3 cycles following a full bin shut down or being
turned on (initial start-up), the unit will perform an “Anti-slush” shutdown of the Water Pump
for 20 seconds when the water temperature reaches 36 degrees F to reduce the possibility of
the water in the Sump slushing. The unit will perform an anti-slush shut down of the Water
Pump any time the water temp reaches 28 degrees F.
Troubleshooting
When the High and Low Floats are in the down position, the contacts for the switches are closed
and the LED’s on the Board should be illuminated.
Low Float Switch LED
High Float Switch LED
As the water level rises, the floats rise with it and the contacts of the switches will open and the
LED’s on the Board will go OFF. This can be verified by removing the Sump and checking first the
LED’s on the Board. Without the presence of water, both floats should be in the down position
and the LED’s on the Board should be illuminated. If one or both LED’s 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.

float. If float is clean and contacts do not change with float movement, replace Float Switch
Housing Assembly. If one or both of the LED’s remain OFF with Float Switches that are known to
be good, the Board or Wiring Harness may be the issue.

WATER PUMP
Water Pump
Operation
Relay 6 on the Board (LED ON) energizes the
Water Pump after the 30 second Pre-Chill of
the Evaporator during the Freeze Cycle. In the
first 3 Freeze Cycles after a shutdown (turned
OFF or Bin Full) the Water Pump will perform
a shutdown for 20 seconds to help prevent
the Sump from slushing. The Water Pump will
then be energized to complete the Freeze
Cycle (see Sequence of Operations pg. 9) The
Water Pump is active continuously during the
Cleaning Cycle after the Sump is filled (see
Cleaning Instructions pg. 56).
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
re-verify. 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 found, the issue is the wiring or connectors. If line Voltage is found, but 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.

WATER DISTRIBUTION TUBE
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.
Removal and Disassembly
Disconnect Water Pump Tube from Water Distribution Tube.
Gentle squeeze the tabs inward on the Water Distribution Tube and forward towards the front of
the unit.

WATER INLET VALVE
Water Inlet Valve
Operation
Relay 4 on the Board (LED ON) energizes the
Valve first on initial start-up 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, reenergized during the Pre-Chill to complete filling the Sump (See Sequence of Operation pg.
9). In either case, Relay 4 will be illuminated
when 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 maximum fill time allowed to open the contacts of the High Float Switch is 5 minutes. If
Relay 4 is illuminated and the Water Inlet Valve doesn’t open, verify water supply to the unit,
then check for line voltage between the Tan and Blue wires on the Molex. If line voltage is not
present, the issue is the Board. If line voltage is present, check for line voltage at the Water Inlet
Valve coil. If no line voltage is present, the issue is the wiring or connectors. If line voltage is
present, check resistance of coil. No resistance = open coil, replace Valve. If coil checks out, verify
Water Inlet Valve for cleanliness and clean or replace as needed. Also verify incoming water supply and for plugged filters.

Purge Valve
Operation
The Purge Valve is located in the back of the

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 is located in 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 and during the Cleaning/Sanitizing Cycle. If Purge Valve fails to open with Relay 5 LED illuminated, unplug Connector at coil of Valve and check for line voltage. If none is found, check
output voltage at Molex at Board between Pink and Blue wires. If no voltage is found, the Board
is the issue. If output voltage is found, wiring between Molex and connector at Valve is the issue.

HARVEST ASSIST ASSEMBLY/HOT GAS 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 energized with the Hot Gas Valve throughout the Defrost Cycle by
Relay 3. To quickly verify operation, put the unit into Diagnostics program by pressing both the
Power and Wash buttons for 6 seconds, then quick press BOTH the Power and Clean buttons
until the Harvest Cycle is initiated (R2 - R6 LED’s above component Molex should illuminate).
Verify LED for Relay 3 is illuminated and check voltage between the Blue and Red wires at Molex.
If no voltage is present, the Board or Molex may be the issue. If voltage is verified, Check for
voltage at the wiring connector for the Harvest Assist. If voltage is verified and the probe is not
pushed forward, the issue is the Harvest Assist.

EVAPORATOR
Evaporator Assembly
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 assure
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 lines continue “serpentining” 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 refrigeration pressures on the Technical Specifications chart on pg. 60.
Should the ice slab resist coming off the plate, examine the Evaporator for lose 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.

The Fan Cycle Control helps maintain head
pressure in cooler ambient temps. The control
closes at 250 psig, energizing the Fan Motor
and opens at 200 psig.
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 re-closes 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.
A dirty or blocked Condenser, failed Fan Cycle Control, failed Fan Motor, high side restriction or
refrigerant over charge can be the cause.
Fan Cycling Control
The Fan Cycle Control closes on pressure rise at 250 psig and opens on pressure drop at 200 psig
to maintain head pressure in cooler ambient conditions. The cut-in and cut-out should never be
erratic. Should the contacts of the control close and/or open outside these parameters, the control should be replaced.

HIGH TEMP SAFETY
High Temp Safety
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
degrees F., the High Temp Safety would open,
dropping power to the Contactor and shut
down the Compressor. When the line temperature drops below 120 degrees F., the contacts of the Safety will close, allowing power
to the Contactor.
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 degrees 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 open with a cool line, the safety will
need to be replaced.

FAN MOTOR
Fan Motor
Operation
The Fan Motor (Self Contained Air Cooled
Units) is Mounted to the Fan Shroud covering

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 should open at
200 psi of head and the Fan Motor will deenergize.
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 Molex connection at the Board and correct if
loose. If 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
Motor does not come on, check connection at Motor. If verified, the issue is the Fan Motor.

REFRIGERATION SECTION
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.
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 and well insulated. Generally a low suction pressure with a normal head
pressure will show as 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.
53
ELEVATION SERIES CIM CUBER
REFRIGERATION SECTION
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 coil
shows open, replace the coil. If coil checks out, place magnetic donut on top of coil. If valve will
not open, replace Hot Gas Valve body. Should suction pressure run high, check temperature of
the inlet and outlet line of the Hot Gas Valve. 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.44.)
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 the 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 ambients, the Mixing Valve should be bypassing the Condenser to maintain head pressure. The inlet and outlet lines at the Condenser would be the same temp. in bypass mode. In
warmer ambients the Mixing Valve is pushing refrigerant to the Condenser Coil and there would
be approx. 20 degree F. temperature difference. A low charge would be identified by hot inlet
and outlet lines at the Condenser and a hot Receiver. Always verify charge before condemning
the Mixing Valve.

CLEANING/SANITIZING PROCEDURES
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 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.
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. Remove the front panel of the ice machine by loosening the two front panel screws with a Phillips head
screwdriver. Lift panel to remove.
3. Press and hold the POWER button for 3 seconds to initiate a harvest cycle (blue light will begin to flash for
Manual Harvest mode). This ensures there is no ice on the plate and the water is emptied from the sump.

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 nonfood-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.
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
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 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.

WINTERIZING PROCEDURES
Winterizing Procedures
IMPORTANT: Whenever the ice machine is taken out of operation during the winter months, the procedure
below must be performed. Failure to do so may cause serious damage and will void all warranties.
1. Turn off water to machine.
2. Make sure all ice is off of the evaporator(s). If ice is being made, initiate harvest by pressing the
Power Button for approximately 3 seconds. The unit will shut off automatically following the
harvest.
3. Disconnect the tubing between the water pump discharge and water distribution tube and drain
any water.
4. On water cooled machines, hold the water regulating valve open by prying upward on the water
valve spring with a screwdriver while using compressed air to blow all the water out of the condenser.
5. Remove all of the ice in the storage bin and discard.
