INSTALLATION INSTRUCTIONS
You will get better service from the ice machine, longer life and greater convenience if you choose its location
with care.
Here are a few points to consider:
1. Select a location as close as possible to where you are going to use the ice.
2. Allow a minimum of 6” space at sides and rear of machine for ventilation.
3. A kitchen installation is not desirable as a rule. If a kitchen installation is necessary, locate the machine as
far away from the cooking area as possible. Grease laden air will form a greasy deposit on the condenser.
This reduces the ice making efficiency and necessitates thorough cleaning quite often.
4. If you install the unit in a storeroom, be sure the room is well ventilated.
NOTE: Do not install where the ambient and incoming water temperature will drop below 50° F rise to
over 100° F.
WARNING: If water pressure exceeds 50 pounds, a water pressure regulator should be
installed in water inlet line between water shut–off valve and strainer. Minimum incoming
water pressure required is 22 pounds.
5. Uncrate the unit by removing the staples or nails from the bottom of the carton and lift off.
6. Remove the bolts holding the skid to the machine.
7. For units supplied with a bin sealing gasket, cement the gasket to the bottom outside edge of the machine
before it is set on the bin. NOTE: This is an N.S.F. requirement and must be done by the installer.
8. Make sure the correct bin adapter has been supplied when used. Then mount the unit on the bin and level
both properly.
9. For units not supplied with bin sealing gasket, seal the machine to bin with an N.S.F. approved sealant
such as Dow R.T.V. #732, 734, or G.E. #102, 108. This is an N.S.F. requirement and is the responsibility
of the installer.
10. The incoming water for the ice making section requires a 3/8” copper line. Connect this water line to the
3/8” male flare fitting on the back of the unit.
NOTE: For water cooled units, a separate 3/8” copper water line is required to be connected to the flare
fitting on the back of the unit marked condenser water in. A 3/8” flare connected line will have
to be provided from the fitting marked condenser water out to the drain.
A water regulating valve installed at the factory was set to maintain 270 to 310 PSI head pressure for R–404a
units and 210 to 225 PSI for R–22 units (Approx. 105_ to 110_F). Check temperatures at condenser outlet and
adjust if necessary.
11. Connect a drain hose to the condensate drain stub tube.
NOTE: All plumbing must be done in accordance with national and local codes.
12. Bring the electrical supply into the unit through a handy box located on the back of unit and make
connections.
NOTE: NOTE: Make sure the proper voltage and number of wires are provided. See serial plate and
make connections.
NOTE: All wiring must conform to national and local codes.
13. Turn on water supply and observe water level in evaporator sections. Water level is to be maintained at
the top of the evaporator. (See adjustment procedure)

14. Turn machine on and check for proper voltage and amp draw on the entire unit as well as components
such as the gearmotor and fan motor.
15. Check refrigerant circuit and all plumbing connections for leaks, etc.
16. Check bin thermostat or mechanical shut–off for proper operations. In the mid–range the bin thermostat
will open at 42° and has a 6° differential.
REMOTE CONDENSER
Remote condensers should be installed above the ice machine and in a level configuration. They are connected
to the ice making unit by copper tubing and line valves. The female half of the line valve is mounted on the ice
making unit and the remote condenser. The male half is soldered on the tube ends when tubing kits are
provided with the machine. If tubing kits are not provided, the male half of the line valves will be provided in a
valve kit and the installer will mount them on the tubing he provides.
NOTE: WHEN VERTICAL LINES ARE INVOLVED IN THE INSTALLATION, FOLLOW STANDARD
REFRIGERATION PRACTICES FOR VERTICAL LINES TO ASSURE POSITIVE OIL RETURN TO
THE COMPRESSOR. VERTICAL LIFT TO BE NO MORE THAN 15 FEET.
NOTE: WE DO NOT RECOMMEND TUBING RUNS OF MORE THAN 40 FEET..
NOTE: The seals for the line valves will be found in an envelope on the remote condenser. Make sure
they are used.
NOTE: REMOVE CAP PLUGS FROM ALL LINE VALVES BEFORE MAKING VALVE CONNECTIONS WITH
THE SEAL.
NOTE: A LOW VOLTAGE ELECTRICAL CONTROL CIRCUIT MUST BE FIELD WIRED BETWEEN THE
ICE MACHINE AND THE REMOTE CONDENSER RELAY. THOSE WIRES SHOULD BE RUN WITH
THE TUBING DURING INSTALLATION. REFER TO APPLICABLE WIRING DIAGRAMS.
NOTE: When the line valves are connected to each other the refrigerant circuit is complete. Each valve
half has its own shut-off which must be fully opened to allow the refrigerant to flow though the
system before it is started.
The ice making unit utilizing a remote condenser is shipped from the factory with the receiver holding the
refrigerant charge. Additional refrigerant may be required upon installation depending upon the ambient
conditions the remote condenser is operating under, the condenser and line sizing.
A three way head pressure control valve is used to maintain a relatively consistent head pressure between 175
and 185 PSI for R22 in the receiver in cold ambient conditions. Because of this valve some liquid refrigerant will
be held in the condenser.
NOTE: THE HEAD PRESSURE CONTROL VALVE WILL NOT OPERATE CORRECTLY WHEN A TOTAL
PRESSURE DROP OF 14 POUNDS OR MORE IS CREATED BETWEEN THE ICE MAKING UNIT,
THROUGH THE TUBING TO THE REMOTE CONDENSER, THE CONDENSER AND THE RETURN
TUBING TO THE ICE MAKING UNIT.
The remote condenser requires a separate power supply from the ice making unit. Refer to the remote
condenser wiring diagram.

TYPICAL WATER CIRCUIT
The supply water enters the float chamber through a small orifice. The water level rises and lifts the buoyant
float with it. The float attached to the float arm seats a valve to shut off any further water supply. As water
leaves the float chamber, the level drops along with the float and arm, causing the valve to open and admit
more water. Thus the water level is maintained automatically as the machine operates.
Water now flows through a hose connected to the float chamber and enters the opening of the evaporator shell.
The water level in the shell will rise to the same level that is maintained in the float chamber. The water that is
in immediate contact with the center post evaporator will be reduced in temperature. As a result, freezing
occurs and ice forms on the surface of the evaporator.
As more water is frozen, the thickness of the ice increases until it exceeds the distance allowed between the
evaporator and auger. The auger rotates at a slow speed to wipe off the accumulated ice as well as help it to
the surface. After the ice reaches the surface it is discharged through the top opening in the shell. An ice chute
attached to the shell conveys the ice to the storage bin where it accumulates in the insulated bin until it is used.
The ice will pile up to a point where the bin thermostat tubing is located. When the ice touches this brass
tubing, the unit will shut–off and remain off until enough ice is used or melted to reduce the pile. Any ice that
melts will pass through the drain and drain hose to an open drain.

TYPICAL REFRIGERANT CIRCUIT
Heat always flows from hot to cold and therefore, the ”heat load” supplied to the evaporator section by water
gives up its heat to the refrigerant which is at a temperature below the freezing point of water. This refrigerant
now passes through the heat exchanger back to the compressor, as a low pressure vapor.
This low pressure vapor is compressed in the compressor, as it leaves the compressor at a high pressure in
vapor form it enters the top of the condenser. The condenser has a rapid flow of cool air across it which
removes much of the heat from the hot refrigerant vapor.
As the vapor, passing through the condenser, loses heat it condenses back to a liquid since it is still under high
pressure and cooler than when it entered the condenser. The liquid refrigerant then passes through the
drier/filter still under pressure and goes through the heat exchanger where further cooling takes place. As the
refrigerant leaves the automatic expansion valve, the pressure has dropped, causing the refrigerant to vaporize
and boil off as it picks up heat in the evaporator and since the pressure is low, the refrigerant will be cold.

ELECTRICAL CIRCUIT
CIRCUIT DESCRIPTION
As the manual on–off–circuit breaker switch is pushed to ”on”, an electrical circuit is completed to the
gearmotor via the circuit breaker gearmotor overload, power relay / contactor, gearmotor delay thermostat and
the bin thermostat. After the previous circuit has been completed the condenser fan motor will start as will the
compressor (via the high pressure control and the compressor starting relay).
COMPONENT DESCRIPTION
BIN THERMOSTAT
This is electrically in ”series” with the ice making system. when the bin is full, the contact opens, terminating
power to the machine.
GEARMOTOR START RELAY
This is a current type relay which means as the gearmotor run winding comes ”on” the line, the current draw
initially is relatively heavy through the relay coil (coil is in series with run winding). It then acts like a normal
relay and the N.O. start contact ”makes”, completing a circuit through the start capacitor to the start winding.
As the gearmotor picks up speed, the amp draw through the relay coil drops off allowing the armature to return
to its normal position (start contact ”opens”). This action removes the start winding from the circuit.
POWER RELAY / CONTACTOR
This relay controls the compressor power only.
GEARMOTOR DELAY THERMOSTAT
This thermostat keeps the gearmotor running until the suction line temperature reaches 45_ after the full bin
switch terminates power to the power relay / contactor.
ON–OFF SWITCH / CIRCUIT BREAKER
This switch interrupts power to the entire unit. The switch has a circuit breaker incorporated into its’ design.
This circuit breaker will trip out in the event the gearmotor draws to high of amps In such an event the power is
interrupted to the unit. To reset the circuit breaker and reestablish power to the unit, push the switch to the ”off”
position and then back to the ”on” position.
FAN CYCLING SWITCH (R404a Units)
The function of this switch is to maintain condensing pressures at a satisfactory level during–low ambient
conditions. The switch breaks the circuit to the condenser fan motor at 205 PSI and makes the circuit at 275
PSI.
HIGH PRESSURE CONTROL
The high pressure cut out is electrically in series with the power relay. As the head pressure rises to 450 PSIG
for R404a charged units and 400 PSIG for R 22 charged units, a preset level, the contact opens thus breaking
the circuit to the compressor via the power relay contactor. This control must be reset manually on R404a units.

COMPRESSOR START RELAY
This is a current type relay and contains a N.O. contact which is connected in series with the start winding of the
compressor. The relay coil is electrically in series with the run winding. When power is applied, the compressor
draws high current which sets up a magnetic field around the magnet coil which causes the relay to operate,
closing the relay contact. As the compressor approaches operating speed, the current flowing through the coil
decreases, permitting the relay contact to open, thereby opening the starting circuit.
POTENTIAL RELAYS
The potential relay is used as a compressor starting relay, The contact in the potential relay is N.C.. The
magnet coil is connected across (parallel) the start winding and is affected by induced voltage, generated by the
start winding. As the compressor comes up to design speed, the voltage across the relay coil increases and at
running speed is sometimes as much as 2 1/2 times the supply voltage. This voltage sets up a magnetic field
which causes the relay to operate. The starting relay is calibrated to remove the start capacitor (open the
starting circuit) at approximately 85% of the motor design speed.
NOTE: BOTH TYPES OF RELAYS ARE DESIGNED TO OPERATE WITHIN VERY NARROW LIMITS OF
VOLTAGE AND CURRENT DICTATED BY MOTOR DESIGN, THEREFORE, WHEN MAKING A
REPLACEMENT OF A RELAY ALWAYS PROVIDE AN EXACT REPLACEMENT, RECOMMENDED
BY THE COMPRESSOR MANUFACTURER.
CAPACITORS – GENERAL
An electrical capacitor is a device which stores up electrical energy. Capacitors are used with single phase
motors to provide starting torque and improve running characteristics; by feeding this energy to the start winding
in step with the run winding.
Any capacitor has three (3) essential parts, two (2) of which are usually foil plates separated and insulated by
the third part called the dielectric.
Two general types of capacitors are used with electric motors. The electrolytic starting capacitor usually uses a
very thin film of oxide on the metallic plate as the dielectric. The running capacitor usually is of the liquid filled
type.

MAINTENANCE
THE FOLLOWING MAINTENANCE SHOULD BE PERFORMED AT LEAST EVERY SIX MONTHS ON
FLAKED ICE MACHINES:
1. Check power supply with machine running for proper voltage.
2. Check water level in the float tank reservoir. Water level should be maintained at the top of the evaporator.
Adjust if necessary. (See illustration and adjustment procedure)
3. Clean the air–cooled condenser coil with a stiff brush or vacuum cleaner (See procedure)
CAUTION: CONDENSER COOLING FINS ARE SHARP, USE CARE WHEN CLEANING.
4. Clean the ice storage bin and flush the bin drain at least once a month.
5. If a water conditioner is installed in the inlet water line, change, replace, or clean the filter, strainer or car-
tridge as required.
6. If heavy mineral deposits on the auger and evaporator shell are encountered due to bad local water condi-
tions, follow sanitizing and cleaning procedure.
7. Loosen hold–down cam locks and remove gearmotor assembly.
8. Check thrust washer; replace if noticeably worn.
9. Lift out auger and examine for wear. The corkscrew auger guide bushing pressed into the drive block
should be checked for wear. Replace if loose or if worn flat with auger drive block. If the Helix auger on
the corkscrew auger round bar becomes flat on the inside more than 1/8 of an inch over a length of two
inches or more it should be replaced.
NOTE: HELIX AUGERS DO HAVE MACHINED FLAT RELIEF SURFACES. DON’T CONFUSE THEM WITH
WORN FLAT AREAS.
Check the insert in the bottom ring of the Helix auger and replace if excessively worn.
10. Check shell vertical strips for wear. Replace the shell if excessive wear is shown.
11. Check O–Ring, replace if worn or cut.
12. Re–assemble, steps 7through 11.
CAUTION: IN RE–ASSEMBLING THE AUGER GEARMOTOR, THE HOLD DOWN CLAMPS
MUST BE RIGHT AND SECURE. IN RE–INSTALLING THE EVAPORATOR SHELL, BE
ABSOLUTELY SURE THAT THE ”O” RING IS NOT PINCHED OFF AS THIS WOULD CAUSE A
WATER LEAK AROUND THE BASE OF THE EVAPORATOR. LUBRICATE THE ”O” RING WITH
FOOD GRADE LUBRICANT BEFORE RE–ASSEMBLING SHELL.
13. Check for alignment of ice chute. Make sure chute gasket is not blocking path of ice flow.
14. Check bin thermostat operation. In the mid–range position the bin thermostat will open at 42_ and has a
6_ differential.

SANITIZING AND CLEANING PROCEDURE
1. Turn switch to ”OFF” to stop unit.
2. Remove top cabinet panel.
CAUTION: Hazardous moving parts. Do not operate unit with panel removed.
3. Mix sanitizing solution by using 0.5-ounces of household liquid bleach (such as Hi-Lex or Chlorox) to one
gallon of potable water. This mixture must not exceed 200-ppm of chlorine.
4. Turn water ”OFF”. Remove water hose from float chamber and allow all water to drain from the float
chamber and evaporator. Restore hose to float chamber and add sanitizing solution to the float chamber.
Turn water ”ON”.
OR
Remove float chamber cover and while holding float up to prevent water from entering the chamber, re-
move water hose and allow all water to drain from the float chamber and evaporator. Restore hose to float
chamber and add sanitizing solution to the float chamber.
5. Reinstall float chamber cover.
6. Remove vertical ice chute cover.
7. With a plastic bristle brush and sanitizing solution, scrub the interior of the vertical ice chute, including the
interior and exterior of the evaporator chute that extends into the vertical chute. Also scrub the vertical
chute cover and sensor tube. Allow all parts to air dry.
8. Reinstall the vertical chute cover and cabinet top panel.
9. Turn switch to ”ON” and allow unit to make ice.
10. Remove or melt with warm water, all ice inside of bin.
11. Using the sanitizing solution from step 7 and brush, scrub the interior of the ice bin including the underside
of the ice bin cover. Scrub the outside of the ice chute that protrudes into the ice bin, and the inside and
outside of the ice bin door.
12. Rinse interior of the ice bin with clean water.
13. Allow machine to make ice for at least 1/2 hour then discard all the ice made. DO NOT ALLOW ICE WITH
SANITIZER IN IT TO BE USED.

WATER TREATMENT
During the freezing process, as water passes under the freezing plate, the impurities in the water have a ten-
dency to be rejected and the plate will freeze only the pure water.
However, the more dissolved solids in the water, the more troublesome the freezing operation will be. Bicarbon-
ates in the water are the most troublesome of the impurities. These impurities will cause scaling on the evapo-
rator, clogging of the water distributor head, float valve mechanism and other parts in the water system. If the
concentration of impurities is high, cloudy cubes or mushy ice may be the result.
Parts of the ice maker, that are in contact with the water or ice, may corrode if the water is high in acidity. In
some areas, water may have to be treated in order to overcome some of the problems that arise because of the
mineral content.
IMI Cornelius has water filter/treatment systems available to control impurities found in your water supply. Con-
tact your local dealer for more information.
WINTER STORAGE
If the unit is to be stored in an area where the temperature will drop below freezing, it is most important that all
water lines be drained to prevent them from freezing and possible rupture.
To blow out the water line, disconnect the water supply at the cabinet inlet and use air pressure to force the wa-
ter into the water reservoir pan. This can then be removed from the water pan.
WATER COOLED CONDENSER – To remove water from condenser unhook water supply and attach com-
pressed air hose. Start machine. As head pressure reaches the appropriate level opening the water regulating
valve, the compressed air will force the water out. Do not let the machine operate longer than necessary.
CLEANING THE CONDENSER (AIR COOLED)
In order to produce at full capacity, the refrigeration condenser must be kept clean. The frequency of cleaning
will be determined by surrounding condition. A good maintenance plan calls for an inspection at least every two
months.
Remove the unit compartment grill at the front. With a vacuum cleaner, remove all accumulated dust and lint
that has adhered to the finned condenser.
CAUTION: CONDENSER COOLING FINS ARE SHARP. USE CARE WHEN CLEANING.

CORNELIUS LIMITED COMMERCIAL WARRANTY PLAN
TO THE ORIGINAL OWNER OF A CORNELIUS COMMERCIAL FLAKE ICEMAKER
This warranty applies to Icemakers installed within the United States, Canada, Mexico and Puerto Rico
only.
For warranty information outside the U.S., Canada, Mexico and Puerto Rico, contact your nearest IMI Cornelius
Sales Office.
PARTS WARRANTY PERIOD
IMI CORNELIUS INC., hereinafter referred to as CORNELIUS, warrants to the original owner of a new CORNELIUS commercial flake ice
machine (“Machine”) who buys solely for commercial uses, that the Machine shall be free from defects in material and/or factory workmanship if
properly installed, operated and maintained, under normal and proper use and service conditions with competent supervision. The parts
warranty period is two years (24 months) from the date of installation or 27 months from the date of shipment by CORNELIUS whichever time
period elapses first. With respect to compressor and the evaporator, and the evaporator only for refrigeration leaks and restrictions which
would effect the normal operation of the unit, the warranty period will be five years (60 months) from the date of installation or 63 months from
the date of shipment by CORNELIUS whichever time period elapses first. The obligation of CORNELIUS under this warranty is limited to repair
or replacement (at the option of CORNELIUS) FOB factory in Mason City, Iowa of the part (or Parts) of any Machine that is proven defective.
LIMITED LABOR WARRANTY PERIOD
In addition to the parts warranty, CORNELIUS will pay scheduled straight time labor to repair or replace a defective component when failure
occurs within one year (12 months) from the date of installation or 15 months from the date of shipment by CORNELIUS whichever time period
elapses first. With respect to the compressor, evaporator, refrigeration condenser, condenser fan motor, and auger gearmotor, the labor
warranty period will be two years (24 months) from the date of installation or 27 months from the date of shipment by CORNELIUS whichever
time period elapses first. Time and rate schedules for labor compensation will be published periodically by CORNELIUS. Additional expenses
including but not limited to travel time, truck charges, overtime charges, material cost, accessing or removal of the ice machine,
normal prescribed maintenance cleaning, adjustments, and ice purchases are the responsibility of the original owner.
No parts warranty or labor allowance on the motor compressor assembly will apply when the ice machine’s refrigeration system is modified with
a condenser heat reclaim device, or parts and assemblies not provided by CORNELIUS, unless CORNELIUS provides approval, in writing, for
these modifications for specific locations.
The parts warranty shall not apply when destruction or damage is caused by alterations, unauthorized service, using other than factory
authorized replacement parts, risks of transportation, accidents, misuse, damage by fire, flood or acts of God. No components or assembly
from which the serial number or identification number has been altered or removed will be covered. Any defective parts to be repaired or
replaced must be returned to us through a CORNELIUS distributor/dealer, transportation charges prepaid, and they must be properly sealed
and tagged. The serial and model number of the Machine and the date of original installation of such Machine must be given. The warranty of
repaired or replaced parts will not extend beyond the period of the original warranty. The decision of the CORNELIUS Service Department
regarding the warrantability of parts and eligibility for the labor allowance will be final.
No representative, distributor/dealer or any other person is authorized or permitted to make any other warranty or obligate CORNELIUS to
make any other warranty or obligate CORNELIUS to any liability not strictly in accordance with this policy. This warranty is in lieu of all other
warranties expressed or implied and of all other obligations or of liabilities on our parts.
OUR LIABILITIES ARE LIMITED SOLELY AND EXCLUSIVELY TO REPAIR OR REPLACEMENT OF THE DEFECTIVE PRODUCT. WE ARE
NOT LIABLE FOR ANY SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES OF ANY KIND WHATSOEVER. In those jurisdictions
where liability for damages cannot be disclaimed, original purchaser’s recovery shall not exceed the cost of the warranted product.
Except for descriptions of size, quantity and type, which may appear on CORNELIUS product with specifications of certain industry,
government or professional organizations standards which may appear as product information disclosures in CORNELIUS literature and other
documents from time to time, THIS WARRANTY IS IN LIEU OF AND EXCLUDES ALL OTHER WARRANTIES, EXPRESSED OR IMPLIED,
INCLUDING WARRANTIES OR MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.
CORNELIUS MAKES NO WRITTEN WARRANTY TO ANY PURCHASER WHO BUYS FOR PERSONAL, FAMILY OR HOUSEHOLD USE.
