INSTALLATION OF SERIES C-0200 and C-0400 CUBER
LOCATION
For best performance select a location away from radiators, ovens, refrigeration condensing units, direct
sunlight and other sources of heat.
Allow a minimum of 5 inches clearance around the cuber for air circulation. Restricted air flow over an air
cooled condenser will adversely affect ice production.
An air cooled cuber will perform more efficiently in a 70° F. room than in a 90° F. room. Recommended
room temperature should not range below 55° F. nor above 100° F.
If the cuber is located in an unheated area, it must be protected from freezing temperatures or shut down
and winterized. Refer to “Winterizing Cuber,” Page 24.
SET-UP OF THE ICE STORAGE BIN
1. Open the top of the ice storage bin carton. Lay the carton on it's back. Remove the internal corrugated
packing and place on the floor adjacent to the bin top. Slide the bin from the carton onto the cardboard
packing to prevent scratching. Screw the legs into the bin bottom.
2. Set the bin in its general location and level by adjusting the legs. The foot of the leg will screw up or
down for adjustment.
MANITOWOC ICE CUBERS — C-0200 & C-0400 SERIES Page 3
REMOVAL OF PACKING AND INSTALLING CUBER
1. To remove the cuber carton, cut the banding and slide the carton up and off the cuber.
2. Set and align the cuber on the bin. Care should be taken to prevent tearing Ye” foam tape around the bin
top.
3. If you desire the bin lid to stay in the open position when raised, make sure the cuber is placed far
enough back on the bin so the lid rests on the cuber front panel.
4. Remove the front panel by pulling forward on the sides near the bottom. Lift up and off. To remove the
wrap-around top and side panel, remove the screws on each side and lift the entire panel forward and
up.
5. Remove the water pump, ice chute, damper door and water curtain from the corrugated carton and
install these components. (Refer to Fig. 2 & 3.)
a. Hang the water curtain over the evaporator and bend each hook 25° outward to prevent the curtain
from falling off during operation. It should swing freely.
b. Plug in the water pump service cord and hang the water pump on the mounting studs. Place the
water tube on the pump discharge.
c. Set the ice chute assembly in place and secure with the knurled thumb screw provided.
6. Remove the water inlet strainer. It will be installed later in the ice making water inlet line. Remove the
wooden wedges from under the compressor.
ELECTRICAL REQUIREMENTS AND CONNECTIONS (See Cuber Specs. Page 12)
All electrical connections should conform to local and national codes. The combination serial and electrical
plate is located inside the cuber above the water pump. The model and serial numbers should always be
used to identify your machine when parts and/or service are required. (Refer to Fig. 2, item 5.)
The cuber should be connected to a separately fused circuit. Fuse size must not exceed maximum fuse size
shown on the electrical plate. The supply voltage should not vary more than 10% above or below the rated
voltage. All electrical wiring must be rated equal to or greater than the minimum ampacity shown on the
electrical plate.
Run the supply wires through the electrical supply hole located on the back panel, Fig. 1, and through the
hole on the back of the control box. Connect the two power supply lines to the black and white leads and the
ground to the green screw located on the base of the control box.
WATER & DRAIN REQUIREMENTS & CONNECTIONS (Refer to Fig. 1, Also see Fig. 5 & 6
for Location Reference.)
All water and drain connections should conform to-local and national codes. We recommend installing a
shut-off valve in both the ice making and condenser water lines. All water and drain lines should be covered
with insulation to prevent condensation.
The ice making cold water supply is connected to a %” female pipe fitting in the rear panel. Use %" O.D.
copper tubing. Install the water strainer in this line with the arrow toward the cuber and the clean-out plug
down.
The condenser water supply is connected to a 3%” female pipe fitting in the rear panel. Use a minimum of
V2" O.D. copper tubing. A minimum of 25 pounds per square inch condenser water pressure must be
maintained at the cuber for proper operation.
Drain connections should not allow waste water to back up into the cuber or storage bin. Drain lines must
have a 12” drop per b feet of run. If drains are not close enough to aliow proper drainage, or water is to be
drained in a stationary sink, an automatic condensate pump will be required.
The bin and cuber drain lines should run separately to an open trapped or vented floor drain. The cuber
drain lines require a minimum 2” 1.D. tubing. The bin drain line requires a minimum 34” |.D. tubing. The
cuber base drain and bin drain lines should be vented to atmosphere. (Refer to Fig. 1.)

OPERATING PROCEDURE (Refer to Fig. 2 & 3)
1. Place the ON-OFF toggle switch in the WATER PUMP position. Only the water pump will operate. Check
for proper water flow through the distributor tube and over the evaporator.
2. With the pump operating, the float valve should shut off the water when the level is just below the top of
the overflow elbow. If necessary adjust the float valve by loosening the two wing nuts and slide the float
assembly up or down as required.
3. Turn the water pump on and off at approximately 1 minute intervals. Do this three times to flush clean
water through the system and inspect for proper drainage.
4. Turn on the cuber by placing the toggle switch in the ICE position; the compressor should operate. The
condenser fan cycles on a pressure control which may delay the starting of the fan motor.
5. Damper door bin switch operation: This switch cycles the cuber from the harvest to freeze mode and
turns the cuber off when the storage bin is full of ice.
To adjust with the cuber operating, hold the damper door open 2-inches. This opens the damper door
switch and stops the cuber until the damper door is released. If the cuber doesn’t stop, bend the switch
arm until proper operation is achieved. (Refer to Fig. 3, Item 9.)
6. On water cooled models, check head pressure, recommended setting is 135 PSIG. Adjust the water
regulating valve (Fig. 6, Item 5) for proper setting.
7. Check bridging of cubes and adjust if needed. For optimum ice production and maximum cube separa-
tion, the ice connecting the individual cubes should be a minimum %" thick at the center rows of the
waffle. Bridge thickness will vary slightly from top to bottom.
FIG. 4
BRIDGE 1/8
To change bridge thickness, an adjustment of the solid state timer is required. This timer is located inside
the electrical control box.
CAUTION: Before removing the control box cover, the cuber's main power supply should be turned off to
prevent any electrical shock or accidental wire shorting.

2. Locate the timer and the dial.
3. To increase bridge thickness, rotate dial clockwise.
4. To decrease bridge thickness, rotate dial counter-clockwise.
Adjustments should not be greater than 10° to 15° at one time. After each adjustment allow the cuber to
produce two ice harvests and observe bridge thickness. Repeat this procedure as required.
Page 8 MANITOWOC ICE CUBERS — C-0200 & C-0400 SERIES
C-0200 & C-0400 SYSTEM CONTROL AND SEQUENCE OF OPERATION
The main ON-OFF toggle switch for the cuber is located on the control box. The toggle switch has three
positions; the center of “OFF” position, the “WATER PUMP” position (only the water pump runs), and the
“ICE” position.
Placing the toggle switch in the Ice position will start the compressor, the condenser fan motor* (air cooled
cubers), and the water pump. The cuber is now in the freeze cycle. As water flows over the evaporator, ice
will begin to form on the cube plate.
As the ice forms, the suction pressure will continually decrease. At a preset point the reverse acting low
pressure cut-in control will close its contacts. 10 PSIG for regular and dice cubes and 11 PSIG for half dice
cubes.
Closing of the low pressure cut-in control contacts energizes the time delay circuit of the solid state timer
through terminal 1. The other side of the line is completed through the safety thermodisc to terminal 2. The
remaining freeze time is dependent upon the timer setting. At the end of the timing sequence the timer
relay will energize. This will open the relay contacts between terminals 4 and 5, shutting off the water
pump and condenser fan motor and close its contacts between terminals 3 and 4, energizing the hot gas
solenoid valve. The cuber is now in the harvest mode.
Shortly after the hot gas solenoid valve opens, the suction pressure will rise to 38 PSIG plus. This opens the
low pressure control contacts. The solid state timer relay remains energized through the timer relay
interlock circuit.
As the harvest cycle progresses the hot gas will warm the evaporator allowing the ice to fall out of the
evaporator and through the ice chute, opening the damper door. Opening of the damper trips the bin switch,
momentarily de-energizing the entire cuber. The timer relay will return to its normal position, de-energizing
the hot gas solenoid and energizing the water pump and condenser fan motor (air cooled cubers). The cuber
is now in a new freeze cycle.
The ice cuber will continue to cycle until the ice storage bin is full. The cuber automatically discontinues ice
production as the ice fills the chute, holding the damper door and the bin switch open.
If, for some reason, the bin switch would fail when the ice falls through the ice chute, the cuber would
remain in the harvest cycle until the hot gas raised the suction temperature approximately 65°F + 5°, At this
time the safety thermodisc, located on the suction line, would open its contacts, de-energizing the timer
relay and hot gas solenoid valve, placing the cuber back into the freeze cycle. As the evaporator begins to
cool, the thermodisc will reclose its contacts at 40°F + 59.
A high pressure cut-out control is used on the water cooled models only. This control shuts the entire cuber
off, should the condensing pressure become too high.
Manually placing a unit into the harvest mode can be done by momentarily pressing the harvest button. Fig.
2, item 9.
"NOTE: The condenser fan motor operates on a high pressure fan cycling control. This can delay the fan
motor from starting when the toggle switch is placed in the ice position.

REFRIGERATION CYCLE — C-0200 and C-0400
*(Assume the cuber is operating at 90°F Air and 70°F Water)
Freeze Mode
During the freeze mode the high pressure discharge gas is pumped into the condenser. (*air cooled-Ave.
head 135-155 PSIG; water cooled-Ave. head 125-135 PSIG.) The high pressure gas is condensed to a high
pressure liquid. The high pressure liquid leaves the condenser, goes through the filter-drier, and into the
heat exchanger. The receiver stores extra refrigerant when it is not used. This depends on operating
conditions.
The high pressure liquid leaves the heat exchanger at a reduced temperature making the system more
efficient. The high pressure liquid is then metered into the evaporator by a thermostatic expansion valve.
The expansion valve regulates the rate of refrigerant liquid flow into the evaporator in the exact proportion
to the rate of evaporation of the refrigerant liquid in the evaporator. The expansion valve does this by
responding to (1) the pressure in the evaporator, (2) the temperature of the refrigerant gas leaving the
evaporator using the valve feeler bulb to sense the gas temperature.
After the low pressure liquid evaporates to a low pressure gas, it passes through the suction line heat
exchanger and into the compressor. The average suction pressure will start at approximately 20 PSIG and
drop to approximately 8-10 PSIG when the cuber goes into harvest.
Harvest Mode
The harvest is initiated by the solid state timer energizing the solenoid valve allowing high pressure hot gas
to flow through the evaporator and harvest the ice. The suction pressure during the harvest is approxi-
mately *45-55 PSIG (air cooled) and 38-45 PSIG (water cooled). *The head pressure will drop to approxi-
mately 80-100 PSIG (air cooled). The cuber goes back into the freeze mode automatically when the solenoid
valve is closed by the harvesting ice tripping the bin switch.
The cuber is now in a new freeze cycle.

CONTROL DESCRIPTION & CHECK-OUT PROCEDURE
TOGGLE SWITCH — Fig. 4, Item 5
The main power “ON and OFF” toggle switch is a double pole, double throw switch with “OFF” in the
center position. With the toggle switch in the “water pump” position, only the water pump will operate. This
is for circulating cleaning solution and checking pump operation.
With the toggle switch in the Ice position, the water pump compressor and condenser fan (air cooled
models) operate for a normal ice making cycle.
TOGGLE SWITCH
(REAR VIEW)
Check Out Procedure — Toggle Switch
1.
2.
Turn power off. Check toggle switch by removing all wires on one side (terminais B, 16 8: 17) and make
continuity check with switch in all three (3) positions with ohmmeter. If the results are positive, rewire
leads to assigned terminals. Likewise examine the opposite side of the toggle switch (terminals A, C. &
14).
Check also the jumper for proper position and continuity. Jumper should be across terminals A & B.
LOW PRESSURE CUT-IN CONTROL — Fig. 4, Item 1
This is a low pressure reverse acting control that closes its contacts on a drop in pressure and opens its
contacts on a rise in pressure. The low pressure control contacts close at 10%: PSIG for regular and dice
cubes, and 11 PSIG for half dice cubes. The differential is fixed at 12 PSIG so the contacts will open at
approximately 22 PSIG.
The low pressure control is used to initiate the timing circuit of the solid state timer. If the timer is set at its
maximum or minimum setting and the proper bridge thickness cannot be obtained, the low pressure control
cut-in point must be recalibrated.
Check Out Procedure — Low Pressure Cut-In
1.
Install a service gage on the suction service valve and voltmeter prods on terminals 1 and the common
binding post “19.”
Turn the cuber on. As it runs, unplug the water pump to discontinue water flow over the evaporator.
This will cause the pressure to fall. When the suction pressure reaches 10-11 PSIG, the contacts
should close giving you a 230 volt reading.
To change the cut-in point, turn the phillip head screw clockwise to increase the cut-in point and
counter-clockwise to decrease the cut-in point.
Allow the timer to time out and place the cuber in harvest. The suction pressure will rise, opening the
low pressure contro! contacts at approximately 22 PSIG.
MANITOWOC ICE CUBERS — C-0200 & C-0400 SERIES Page 17
HIGH PRESSURE CUT-OUT — WATER COOLED UNITS ONLY — Fig. 4, Item 3
This high pressure cut-out shuts off the entire cuber, should the head pressure exceed 275 PSIG. If the
cuber goes out on high head pressure, the high pressure cut-out control has to be manually reset after the
cause of the high head pressure condition has been corrected.
Check Out Procedure — High Pressure Cut-Out
With the power supply turned off to the cuber, place an ohmmeter across the terminals after removing one
of the leads. Push reset button. If no continuity reading, replace control.
SOLID STATE TIMER — Fig. 4, Item 6
The primary function of the timer is to control the ice bridge thickness in conjunction with the low pressure
control {length of the freeze cycle) and to initiate the harvest cycle by energizing the hot gas solenoid valve
and de-energizing the water pump and condenser fan motor. The timer is activated by the low pressure cut-
in control and is de-energize by the opening of the bin switch or thermodisc.
The ice cuber models C-0200 and C-0400 are manufactured with four different make solid state timers. All
four timers are interchangeable. The wiring is the same — be sure the numbered wires are placed on the
terminals with corresponding numbers. When replacing the timer, check jumper wire for proper location,
terminals 2 to B for 115 volt.
Solid State Timer Adjustment — See Operating Procedure, No. 7, Page 7
Check Out Procedure — Solid State Timer (P/N 24-0623-9)
To benchtest timer: set the jumper wire for proper voltage, set the timer to minimum, and apply line
voltage across terminals 1 and 2. The small mechanical relay should energize in less than 30 seconds and
remain energized until either power leg is disconnected. Exception: Timer made by omnetics, their P/N
J1103, needs a jumper wire from terminals No. 1 to No. 4. Without jumper, the relay will chatter when
energized.
Trouble shooting timer in unit: when unit is freezing but not cycling into the harvest mode, make the
following checks. Do not switch the unit off or defrost the evaporator until the service sequence below has
been followed.
1. Check for line voltage between terminals #1 and #2 on the timer. If line voltage is there, check for
proper installation of the jumper wire and turn the timer to the minimum setting. If the unit does not
switch into the harvest mode at this time, replace the timer.
2. If you do not get line voltage between terminals #1 and #2, check for voltage between #2 and #4. If no
line voltage between #2 and #4, see thermodisc check out procedure.
3. If you had line voltage between #2 and #4, the thermodisc is closed and not the cause of the problem.
Check for voltage between terminals #19 and #1. If you do not have line voltage, the low pressure
control is open.
4. If the suction pressure is below the cut-in point of the control, the problem is with the control itself. The
control will require readjustment or replacement. See low pressure cut-in check out procedure.
5. If the suction pressure is above the cut-in point of the low pressure control, the refrigeration system
operation must be analyzed. Check the following:
Excessive head
Improper charge
Expansion valve flooding
Hot gas solenoid valve leaking
Inefficient compressor

DAMPER DOOR MICRO SWITCH — Fig. 4, Item 4
This micro switch is used to cycle the cuber from harvest to freeze cycles and shut the cuber OFF when the
ice bin is full. The switch is tripped by the damper door counterweight when the harvesting ice falls through
the ice chute.
Check Out Procedure — Damper Door Micro Switch
1. Check free movement of damper door.
2. Check bin switch arm for ON and OFF action, by opening or closing damper door. Switch should open
when the damper door is open approximately 1-12" to 2" shutting cuber off.
3. Turn main power supply off to the cuber. Make a continuity check across the switch. Be sure to remove
one lead first. Tripping the metal arm will open the switch contacts, and releasing the arm will close the
contacts. To verify switch action, open and close the switch. Replace switch, if defective. The two leads
should be wired to the normally closed terminals.
FAN CYCLE CONTROL — Fig. 4, Item 2
This is a high side pressure control that cycles the fan motor off at approximately 100 PSIG and on at 135
PSIG. The purpose is to maintain a minimum head pressure for proper operation.
Check Out Procedure — Fan Cycle Control
1. Install a service gage on the high side service valve.
2. Turn the cuber on; as the unit runs, note the pressures the fan motor cycles. If adjustment is needed,
turn the phillip head screw clockwise to increase the cycling pressures and counter-clockwise to
decrease the cycling pressures. The differential is fixed.
MANUAL HARVEST BUTTON — Fig. 2, Item 9
This is a momentary push button that will place the unit in the harvest mode to clear the ice for cleaning or
servicing.
Check Out Procedure — Manual Harvest Button
1. Turn main toggle switch OFF.
2. Remove the leads from H and Hq on the timer. Place voltmeter prods across the two leads. Depressing
the button should give you a continuity reading; releasing the button should give no reading.
SAFETY THERMO-DISC — Fig. 5, Item 1
The thermo-disc is a safety control located on the suction line. The control is temperature sensitive and
opens at 70°F + b°F. The thermo-disc prevents the cuber from overheating. If the bin damper door switch
should fail when the ice harvests, the cuber hat gas valve would remain open. The suction temperature
would rise and the thermo-disc would open at 70°F. This will place the cuber back into the freezing cycle by
de-energizing the timer and hot gas solenoid.
Check Out Procedure — Thermo-Disc
1. The thermo-disc is a normally open control at 70°F and above, and recioses at 40°F. Closing is
accomplished by operating the cuber on for approximately 5 minutes. The thermo-disc will open only if
the cuber sits idle in room temperature for a period of time, or the cuber bin switch fails in harvest.
2. Disconnect the thermo-disc leads at terminals #2 and #19 of the timer, after the cuber has been
operating. Check continuity with ohmmeter. If there is no reading, check for contact between the
suction-line and the thermo-disc. If contact is adequate, replace thermo-disc.
MANITOWOC ICE CUBERS — C-0200 & C-0400 SERIES
Page 19
To check the cut-out temperature of the thermo-disc, remove the damper door from the ice chute. Start
the cuber and wait for the evaporator to harvest. With the door removed, the unit will remain in its
harvest cycle. This will increase the suction line temperature sharply until the thermo-disc reaches its
calibrated opening point (70°F + 5°F). From the time the ice has harvested to the point the thermo-disc
opens, under normal ambient temperatures, it should take no longer than 2-3 minutes.
WATER REGULATING VALVE (Water Cooled Condensers) — Fig. 6, Item 5
The water regulating valve is used on water cooled cubers only. The valve is mounted in the incoming
condenser water line. Its primary function is to maintain the proper head pressure by controlling the
amount of water flow through the condenser. The valve is adjustable and should be set to maintain a 125
PSIG + 5 PSIG operating head.
Check Out Procedure — Water Regulating Valve
1.
2.
Install a gage on the high side of the system, either on the discharge valve or the receiver valve.
The water valve has an adjustment knob on the top of the valve. With the cuber operating and while
watching your high side gage, adjust the valve until the cuber head pressure is in the 125 PSIG range.
The water regulating valve should shut off completely during the harvest cycle. This can be checked by
looking at your condenser water drain or removing the flare fitting on the out-let side of the valve. If the
valve fails to close during harvest, the condenser will condense the hot gas needed for harvesting the
ice.
CHECK OUT PROCEDURE FOR COMPRESSOR AND STARTING COMPONENTS
(A) Compressor will not run —
If the compressor fails to start and run properly, it is possible that the external electrical components
may be defective, the protector may be open, a safety device may be tripped, or other conditions may be
preventing compressor operation.
1. Check the voltage at compressor terminals. If there is not voltage, check back from the compressor
to the power supply to find where the circuit is interrupted. Check across terminals #17 on toggle
switch and 419 on timer. If no voltage check the following: overload on compressor (allow 10
minutes to reset), bin switch, high pressure cut-out (water cooled units only — has a manual reset
on the control), the toggle switch for proper operation.
2. |f power is available at the compressor terminals and the compressor does not run, check the
voltage at the compressor while attempting to start the compressor. If the voltage is below 90% of
the nameplate voltage, it is possible the motor may not develop sufficient torque to start. Check to
determine if the power supply is adequate, electrical connections are loose, the circuit is over-
loaded, or if supply wire sizes are adequate.
3. A defective capacitor or relay may prevent the compressor starting. If the compressor attempts to
start, but is unable to do so, or if the compressor hums or trips out on the overload protector, check:
(Disconnect Power to unit Before Proceeding.)
RELAY — Current Type
Pull relay off compressor terminals — keep upright! The relay contacts should be open, check
continuity with ohmmeter — if relay contacts are closed, replace relay.
Check continuity through the relay coil, replace relay if no continuity.
CAPACITORS —
Any capacitor found to be bulging, leaking, or damaged should be replaced.
Caution: Before removing leads for testing purposes, short across capacitor that do not have bleed
resistors to discharge capacitor.
Page 20 MANITOWOC ICE CUBERS — C-0200 & C-0400 SERIES
A quick check is to replace suspected capacitors with a known good capacitor. Be sure specified
capacitors are used.
If a capacitor tester is not available, an ohnmmeter may be used to check start capacitors for shorts
or open circuits. Set the ohmmeter to its highest scale, and connect prods to capacitor terminals.
A. With a good capacitor, the indicator should first move to zero, and then gradually increase to
infinity.
B. If there is no movement of the ohmmeter indicator, an open circuit is indicated.
C. If the ohmmeter indicator moves to zero and remains there or on a low resistance reading, a short
circuit is indicated.
(В) If the compressor fails to start or blows fuses (start relay and capacitor is functional), proceed to check
compressor as follows:
CAUTION: Turn power off. Before removing supply leads to compressor short across both capacity
terminals to discharge capacitors.
1. Using an ohmmeter check for continuity from terminals C to R, and C to S. If the compressor is
warm, wait one hour for compressor to cool and recheck. The internal overload protector can cause
a lack of continuity. If continuity cannot be established through all motor windings, the compressor
should be replaced.
2. Check compressor motor for ground by means of a continuity check between terminals C, R, and S
to the compressor shell or copper refrigeration line (be sure to scrape metal surface clean to get
good contact). If no continuity reading, the compressor windings are grounded and the compressor
should be replaced.
(C) If compressor starts but trips repeatedly on the overload protector, check:
——
- =
1. Operating pressures should be within limitations of normal operating conditions shown on Rage
2. Check the line voltage at the motor terminals while the compressor is operating. The voltage
should be within 10% of nameplate voltage. If outside those limits, the voltage supply must be
brought within the proper range.
3. Check the amperage drawn while the compressor is operating. Under normal operating conditions,
the continuous amperage drawn will seldom exceed 100% of compressor nameplate amperage and
should never exceed 120% of nameplate amperage. High amperage can be caused by:
Low voltage.
High head pressure.
High suction pressure.
Defective running capacitors or starting relay.
Compressor mechanical damage.

CLEANING INSTRUCTIONS
Efficient operation requires periodic cleaning.
Cleaning frequency will depend largely on water conditions. If you have hard water or high concentrations
of impurities, water treatment filters may be needed to improve ice quality and reduce cleaning frequency.
Check with local water treatment firms for advice.
The ice making water supply strainer should be cleaned every time the water system is cleaned. (Refer to
Fig. 1.) Proceed as follows:
1. Turn off the water supply.
2. Remove the plug and strainer.
3. Clean the strainer and replace.
CLEANING OF THE ICE MAKING SECTION
We recommend two ice machine cleaning solutions. They are Lime-A-Way from Economics Laboratories or
Nickel-Safe from Calgon. Other cleaners from the same or other companies may be harmful to the nickel
plating on the evaporator. Lime-A-Way can be purchased from Manitowoc ice machine distributors.
Manitowoc's part number is 94-0546-9.
IN PLACE CLEANING
To clean the water system without removing the components proceed as follows: This method is acceptable
when build-up is not excessive.
Remove front panel.
Remove any existing ice in the evaporator by pushing the manual harvest button.
Turn cuber off and remove all ice from bin.
. Drain the sump trough water.
Pour 1 oz. of Lime-A-Way or Nickel-Safe cleaner in the sump and fill with fresh water.
Flip the toggle switch to the WATER PUMP position. Circulate the cleaner for a maximum of 15 minutes.
If not sufficiently clean, proceed to hand cleaning instructions.
7. Flip the toggle switch to the OFF position, drain the water and cleaner solution. Proceed to “Sanitizing
| Procedure.”
HAND CLEANING (Refer to Fig. 2 & 3)
Used when material build-up is too severe for “in place cleaning.”
1. Turn the cuber and the water supply off. Remove the water pump, water distributor, water curtain, sump
trough and ice from the bin.
2. Use a cleaning solution of 2 oz. of recommended cleaner per one gallon of warm water.
3. Soak the water distributor in a hot cleaning solution while cleaning the remaining parts. If necessary, the
distributor tube can be disassembled.
4. Snap the water pump inlet screen out and clean.
5. Scrub all parts using a nylon brush and cleaning solution.
6. Scrub the base and evaporator assembly. Clean and flush the base drain. With a small brush, clean the
weep holes in the corner of each evaporator cube cavity. Rinse with clear water.
7. Replace all the internal components and proceed to ‘Sanitizing Procedure.”
STORAGE BIN CLEANING
1. Scrub the bin interior with 1 oz. of recommended cleaner per gallon of water. This solution may be used
to clean other water and ice contact surfaces.
2. Rinse with clear water.
SANITIZING PROCEDURE
1. Reassemble unit.
2. Mix one teaspoon of solium hypochlorate (chlorine bleach) in one gallon of water. Fill sump trough.
3. Place toggle switch in WATER PUMP position and continue to add solution until the pump is fully primed.
Circulate solution for one minute.
4. Turn off water pump and drain solution from sump trough into the bin to sanitize the bin.
5. Turn on the fresh water supply and allow the sump to fill. Flush the system several times by running the
water pump at 1-minute intervals and then drain the sump.
Flush the bin out several times with clean water.
Turn cuber on by placing toggle switch in ICE position.
. Make a visual inspection for leaks, drainage and proper water level and flow. Check all components for
proper location and tighten all screws before replacing front panel. See Operational Procedure for
adjustment.

CLEANING OF STAINLESS STEEL TRIM AND CHUTES
Stainless steel can show signs of brown staining or rusting when exposed to certain chemicals such as
chlorine. This chlorine gas is expelled during the ice making process and will combine with water vapor and
condense on stainless steel surfaces as a Hydrochloric Acid. The stainless metal parts should be cleaned
periodically to prevent this staining from causjng pitting of the stainless steel.
1. Empty Ice Bin and disassembly per disassembly instructions for cleaning.
2. With frequent cleanings an ordinary cleaning powder such as Copper-Glo or Bon-Ami with water will
remove the brown staining. Do not use any bleaching agents with chlorine compounds. Rinse tho-
roughly with clean water. :
3. If very heavy deposits and pitting have occurred, a chemical cleaner such as Oakit No. 33 from Oakit
Productions, Inc. may be needed. Use one part cleaner to two parts water with chemical cleaners.
4. Clean the stainless steel with soap and water as described above. Then swab the solution over the
stainless steel surfaces and let stand for 15 minutes. Rinse with clean water and repeat as necessary
to completely remove staining.
Be sure to read instructions for safety precautions when using any chemical cleaner. These cleaners
could be harmful to surfaces and materials other than stainless steel.
PROTECTING STAINLESS STEEL SURFACES
To help protect stainless steel against staining the surface should be treated with a Nitric Acid solution of
one part Nitric Acid to two parts water.
1. Clean the stainless surface and rinse thoroughly with clean water.
2. Then swab the Nitric Acid and water solution on the stainless steel and allow to stand for approxi-
mately 30 minutes.
3. Thoroughly rinse the stainless surface and the storage bin with clean water.
AIR COOLED CONDENSER CLEANING
The air cooled condenser should be cleaned frequently. A dirty condenser restricts air flow, causing reduced
ice production.
1. Turn off main power supply.
2. Remove the front and wrap-around panels. Most dirt will collect on the inlet side of the condenser. This
is opposite the fan motor.
3. Use a stiff brush to work the dust and dirt loose and remove with a vacuum cleaner.
4. If the cuber is located in an area where grease collects on the condenser, scrub with a solution of warm
water and detergent. Keep solution away from wiring and electrical components.
. Clean fan blades.
. Check for loose items before replacing panels.
O O1
WINTERIZING CUBER
If the cuber is located in an unheated area, it must be protected from freezing temperatures or shut down
and winterized. When the cuber is shut down for the winter, it is very important that all water be removed
from the cuber. Refer to Fig. 2 & 3.
— Turn main ice water and condenser water (if water cooled) supply valves off, disconnect and drain all
water lines.
— Drain the sump trough by removing the overflow elbow.
— On water cooled models it is very important to completely drain the condenser. After the main water
line has been disconnected, the outlet water line on the water regulating valve should be discon-
nected. All water should be forced from the condenser with compressed air. Any water left in the
condenser can freeze and cause serious damage.
