— UNCRATING
Page 3
} The C-0600 Series cuber is shipped separate from the storage bin, in a corrugated carton. Remove the
staples around the lower edge of the carton. Lift the carton upwards and off. The shipping skid is mounted
to the cuber with 4 bolts located on the underside of the skid. Remove the bolts and set the cuber on the
storage bin.
LOCATION
For maximum efficiency, pick a location away from sources of heat like radiators, ovens, other refrigeration
condensing units, direct sunlight, etc. Provide a minimum of 5 inches around the cuber for proper air
circulation through the compressor compartment. For air cooled models, louvered openings should be 5
inches from the nearest obstruction for best operation. Reduction of clearance may result in increased heat
load and reduced ice capacity. A self-contained air cooled cuber will operate more efficient in a room of 70°
F. than in a room of 90% F. Recommended minimum room temperature is 55° F. for self-contained air
cooled models. If cuber is located in an unheated area, it must be protected from freezing or shut down and
drained, see low ambient operation.
LOW AMBIENT OPERATION AND WINTER SHUTDOWN -
If the ambient temperature is below 55° F. for a self-contained air cooled C-0600, a low ambient kit,
Fancycling switch, P/N 89-5009-9, should be installed. This is not required on water cooled and remote
models.
All Manitowoc cuber models must be protected from freezing temperatures or be shutdown and the water
lines drained. This includes blowing out the ice water supply lines and drains and the water cooled
condenser. To blow the water out of the water cooled condenser the waterlines flare fittings must be
removed from the water regulating valve. The water lines and the condenser can now be blown out. See
Fig.6 Item 9.
SERIAL & ELECTRICAL PLATE (Fig. 2)
, The combined serial and electrical plate is located inside the cuber above the water pump. Be sure to give
| } the complete model number and serial number when calling for service or ordering parts.
REMOVAL OR INSTALLING FRONT PANEL
Caution: when removing front panel mounting screws, hold panel in place until both screws are removed.
Secure panel with both hands and lift up slightly and out. To install front panel with cover on, slide the top
of front panel under the lip of the cover and set in place. Replace the two screws to secure panel.
REMOVING TOP COVER & COMPRESSOR COMPARTMENT PANELS
The top cover is held in place with four sheet metal screws, two on each end. The rear grille must be
removed before the R.H. end panel can be taken off. The rear grille is held in place with four sheet metal
screws. The R.H. end panel is held in place with five screws along the bottom edge; (1) on front flange, (3)
on side, (1) on rear flange.
REMOVAL OF INTERNAL PACKING
Remove the following:
— The tape securing the splash curtain, water pump & ice chute.
— Remove the ice chute and the corrugated board from around the chute and the. plastic sheet from over
the chute. Then replace the ice chute and damper door and secure the chute with the clips and thumb
screws provided.
— Remove the packing from under the water pump.
— Remove the wooden wedges from under the compressor.
— The box taped in the evaporator section contains the strainer for the ice making water supply line.
GENERAL REQUIREMENTS
All electrical, water supply, and drain connections must conform to local and national codes.

Page 4 MANITOWOC ICE CUBERS — C-0600 Series
CONNECTING POWER SUPPLY
1. Use electrical wire rated equal or greater than the minimum ampacity rating given on serial plate.
2. Cuber must be on a separately fused circuit, which does not exceed the maximum fuse size on serial
plate.
3. Check supply voltage, limits are 208 -5% to 230V + 10%
A ground screw is provided in the supply box.
9. Connect supply wires to cuber leads L4 and Lo located inside electrical supply handbox, in the rear of
the compressor compartment. Fig. 3.
WATER SUPPLY
Quality and ice making capacity are affected more by chemistry, temperature, and foreign matter in supply
water than any other factor. A survey made of water departments of large cities all over the country made it
obvious that external filters or strainers should be installed. Such equipment is very effective in improving
ice quality and reducing the frequency of cleaning out the ice making section. Any questions as to the type
of water filter or strainers to be used can be answered by your local water treatment company or water
department. A minimum water pressure of 25 PSIG is required at the water cooled condenser for water
cooled models.
CONNECTING WATER SUPPLY (Fig. 1)
A 1/2” female pipe fitting is provided in the rear panel of the ice cuber. Install the water strainer provided
with the cuber. Use a 3/8 OD copper tubing for the ice making water supply, and a minimum of 12 OD
copper tubing for water condenser supply, on water cooled cubers.
L
DRAIN CONNECTIONS
It is essential that drain connections be made so waste water cannot back up into the head unit or bin. On
water cooled models, a separate drain connection is provided for discharging condenser water (Fig. 1). All
connections are labeled. We recommend covering all incoming water and drain lines with a plumbing
insulation material to prevent condensation.
We recommend that the bin and cuber drains are not tied together and they are run to an open trapped and
vented drain.
If the cuber drain line is tied in directly to the drain, we recommend using a у 1.D. tubing and a stand pipe
vented to the atmosphere to prevent water traps.
Drains must be at least ¥2" inside diameter copper tubing or %" piping and have 1%" drop per 5 feet of run.
If drains are not close enough to allow drop for proper drainage, or water is to be drained in a stationary
sink higher than ice machine drains, use an automatic condensate disposal pump. (Check and follow local
plumbing codes.)
Bin Drain — The bin is supplied with 34” FPT fitting and a min. 3%” pipe or 34" 1.D. copper tubing is
recommended for the drain line.
CHECK LIST FOR START-UP
1. Remove all internal packing!
2. Be sure the cuber is level! This is to insure proper water flow in the cuber.
3.- Turn the supply water on for the sump and the condenser (if water cooled).
4
. Turn the toggle switch Fig. 4 to “water pump”, position. This will start the water pump only, pumping
water to the water distributor and over the evaporator. Check the position of water distributor to see
that it is distributing water properly and evenly over the evaporator. See Fig. 5 for proper distributor
MANITOWOC ICE CUBERS — C-0600 Series Page 5
location. Set the float in the sump to maintain a level of 1/4" below the top of the overflow tube, while
the cuber is running. Should the float valve require adjustment, bend the float rod carefully until
desired water leve! is achieved.
. Turn the water pump on and off (at approx. 2 minute intervals) several times to flush clean water
through the system, and to observe that the flush water drains properly.
. Check all the refrigerant lines and conduit to guard against vibrations and possible failure.
7. Check all the water connections for leaks.
. Bend the water curtian hooks slightly to the outside to secure the water curtain in place. These hooks
can be seen in Fig. 4.
9. Replace the panels except for the front panel.
10. To start cuber place the toggle switch in the “ICE” position.
FINAL CHECK LIST AFTER START-UP
1. With the cuber operating, reach in and push the damper door open about 1” to 1". This should open
the damper (bin) door switch which will shut down the entire cuber. The cuber will remain OFF until
the damper door is released. If the bin switch needs adjustment, bend the metal arm until proper
operation is obtained.
Cuber should be checked for several harvests of cubes to see that the cuber functions properly, and that
the ice cube bridging between cubes is 1/8” in the center of the ice slab. If the bridging needs
adjustment see timer check-out procedure. Page 20.
Is there 5” clearance around cuber for proper air circulation?
Is the room ambient maintained at a minimum of 55° F during winter months, air cooled cubers? NOTE:
A. condenser fan motor thermostat is available for operations below 55° F. (This does not protect the
cuber from freezing temperatures.)
5. Check water and drain connections for water leaks.
6. Has owner been instructed on how to operate and clean the cuber?
Has installation and warranty registration card been filled out? This is for owner protection.

^-9600 SYSTEM CONTROL AND SEQUENCE OF OPERATION
_.¢ main ON-OFF toggle switch for the cuber is located on the control box. The toggle switch has three
positions; the center or “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 through terminals 4 & 5 on the solid state timer. 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 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 & 5 shutting
off the water pump and condenser fan motor and close its contacts between terminals 3 & 4 energizing the
hot gas solenoid valve. The cuber is now in the harvest cycle.
NOTE: To manually place the cuber in harvest, see timer description and check-out procedure. Page 21.
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
ow 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 to 70° 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 + 5°.
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. :
See page 22 Bin Thermostat for CY-O614AS & CY-0615WS models.
REFRIGERATION CYCLE — C-0600 (See Page 15)
*[Assume the cuber is operating at 90° F Air and 70° F Water)
Freeze Cycle
During the freeze cycle the high pressure discharge gas is pumped into the condenser. (*Air cooled-Ave.

head 160-165 PSIG. Water cooled Ave. head 125-130 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. On water cooled cubers the liquid will go from the condenser into a receiver. 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 ave. suction pressure will start at approx. 20 PSIG and drop to
approx. 8-10 PSIG when the cuber goes into harvest.
Harvest Cycle
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 approx. *45-
55 PSIG (air cooled) and 38-45 PSIG (water cooled). *The head pressure will drop to approx. 80-100 PSIG
(air cooled). The cuber goes back into the freeze cycle automatically when the solenoid‘valve is closed by the
harvesting ice tripping the bin switch. |
The cuber is now in a new cycle.

C-0600 COMPONENT CHECK-OUT PROCEDURE |
Check out procedure for compressor and compressor start components. y
(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 for voltage at compressor terminals. If there is no voltage, check back from the compressor
to the power supply to find where the circuit is interrupted. Check the bin switch, high pressure
cut-out (water cooled units only — has a manual reset on the control) and the toggle switch for
proper operation.
2. If 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 from 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:
RELAY — Potential type.
The relay contacts should open as the compessor comes up to speed.
Remove the wire leads from the relay terminals. Use a high voltage ohmmeter to check for
continuity through the relay coil. Replace the relay if there is no continuity.
Use an ohmmeter to check across the relay contacts. Potential relay contacts are normally closed —
when the relay is. not energized. Replace the relay if there is no continuity. ( J
CAPACITORS Fig. 3
Any capacitor found to be bulging, leaking, or damaged should be replaced.
CAUTION: Before removing leads for testing purposes, short across capacitor terminals to dis-
charge capacitor.
A quick check is to replace suspected capacitors with a known good capacitor. Be sure only
specified capacitors are used.
If a capacitor tester is not available, an ohmmeter may be used to check run and start capacitors for
' shorts or open circuits. Set the ohmmeter to its highest resistance scale, and connect prods t 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.
С. If the ohmmeter indicator moves to zero and remains there or on a low resistance reading, a
short circuit is indicated.
(В) If compressor fails to start or blows fuses (start relay and capacitors are functional) proceed to check
compressor as follows:
CAUTION: Turn power off. Before removing supply leads to compressor, short across both capacitor
| 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 compressc
should be replaced. u
2. Check the compressor motor for ground by means of a continuity check between terminal C, R, and
S to the compressor shell. If there is a continuity reading, the compressor is grounded and should
be replaced.
Page 18 MANITOWOC ICE CUBERS — C-0600 Series -
AC) If compressor starts but trips repeatedly on the overload protector check:
/ 1. Operating pressures should be within limitations of normal operating conditions shown on Page
13.
2. Check line voltage at the compressor terminals at start-up. Design voltage is nominal 208 or 230
voltage. Minimum operating voltage 198 and maximum operating voltage is 250.
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.
FAN MOTOR Fig. 3
The fan motor is a shaded (4) pole, impedance protected fractional horsepower motor; normal speed approx.
1610 RPM.
Check Out Procedure
1. Check wiring and voltage across terminals 5 & 19.
2. If there is power, place toggle switch into neutral position. Remove lead from the fan motor at timer
terminal 5. Check fan motor resistance.
) If the windings appear to be open and fan motor is hot, allow 30 minutes for the overload to close and
: recheck. If there is still no reading, the motor is defective. Replace.
4. If the motor appears hot and fan shaft is tight, remove oil plug and lubricate bearings. A good
refrigeration oil can be used. If motor remains tight, replace.
WATER PUMP
Recirculating pump used to pump supply water to the water distributor tube.
Fig. 7 shows dissembly of the water pump for cleaning and to remove the Stainless steel mounting bracket
and pump cover.
HOT GAS SOLENOID VALVE Fig. 3
The hot gas solenoid is a normally closed valve that is opened to permit hot gas flow through the evaporator
to harvest the ice.
Check Out Procedure
1. Check the coil resistance at lead No. 2 & 3. Remove one lead to isolate coil.
2. If the coil is good, check the thermodisc and timer.
3. If the solenoid valve leaks when closed or will not open, but the coil is 5 good, the internal parts should
be examined and replaced if necessary. The refrigerant charge will have to be blown to accomplish this.

C-0600 CONTROLS DESCRIPTION AND CHECK-OUT PROCEDURE
ELECTRICAL CONTROL BOX Fig. 6
The control box contains the high pressure control (water cooled units only), low pressure cut-in, toggle
switch, and the solid state timer. The control box is located inside the evaporator compartment, mounted on
the partition panel. Fig. 4
TOGGLE SWITCH
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.

A
Check Out Procedure о | |
1. Turn power off. Check toggle switch by removing all wires on one side (terminals B, 16 & 17) and make
continuity check 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).
2. Check also the jumper for proper position and continuity. Jumper should be across terminals A & B.
HIGH PRESSURE CUT-OUT — WATER COOLED UNITS ONLY. Fig. 6 tem: 6
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
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.
LOW PRESSURE CUT-IN CONTROL Fig. 6 Item 5
This is a Robert Shaw 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 10-1/2 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 approx. 22 PSIG.
The low pressure control is used to initiate the time delay circuit of the solid state timer. If the timer is set at
its max. or min. setting and the proper bridge thickness cannot be obtained, the low pressure control cut-in
point must be recalibrated.
Check Out Procedure
1. install a service cage on the suction service valve and voltmeter prods on terminals 1 and the common
binding post “19”. | |
2. Turn the cuber on. As it runs slowly close the suction service valve down (front seat) so the suction
pressure will fall. When the suction pressure reaches 10-12 PSIG the contacts should close giving you
a 208/230 volt reading. |
3. 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. Fig. 6 Item 4.
4. Allow the timer to time out and place the cuber in harvest. The suction pressure will rise, opening the
low pressure control contacts at approx. 22 PSIG.
Page 20 MANITOWOC ICE CUBERS — C-0600 Series
SOLID STATE TIMER Fig. 6
‘primary function of the timer is to control the ice bridge thickness 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-energized by the opening of the bin switch, or
thermodisc.
The Model C-0600 Ice Cubers are manufactured with several different make solid state timers. All these
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 for proper voltage setting —
determined by the location of the jumper wire.
— All Dual Voltage Timers P/N 24-0623-3, place a jumper wire across terminals 2 & A for 230 Volt or
across terminals 2 & B for 115 Volt units. The jumper wire must be in place for the timer to operate.
SOLID STATE TIMER ADJUSTMENT AND BRIDGING
TIMER. ADJUSTMENT TO INCREASE OR DECREASE BRIDGING BETWEEN CUBES.
To adjust the solid state timer —
1. Remove control box cover, Fig. 4, item 1.
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 16° at one time. After each adjustment allow the cuber to
produce two ice harvests and observe bridge thickness. Repeat this procedure as required.
For optimum ice production and maximum cube separation, the ice connecting the individual cubes should
be 1/8” thick at the center of the ice slab. (Note: Bridging will vary in the thickness from top to bottom of
e—norator.)
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.

MANITOWOC ICE CUBERS — C-0600 Series Page 21
Check Out Procedure
1. Check wiring of timer to wiring diagram page 14. Cd
2. Set toggle switch to OFF position. Place a jumper wire across the low pressure control.
3. Mark approximate position of timing dial and turn fully counterclockwise to get a short time delay
period (30 to 60 sec.). 4
4. Place the toggle switch into ice making position. The timer, fan motor, water pump, and compressor
should be energized. With the low pressure control jumpered, check for a 230 voltage reading at
terminals 1 and 19 or N with a voltmeter. Note: After the hot gas valve opens, the suction pressure will
rise opening the low pressure contacts.
5. At the end of a predetermined timing period, the timer relay contacts should transfer, turning the fan
motor and water pump OFF, and energizing the hot gas solenoid. Using a voltmeter there should be a
230 voltage reading at terminals 3 and 2 confirming proper operations.
6. If the relay contacts fail to transfer after 2-3 minutes with the timer set at minimum setting, check to
see if the thermo-disc and bin switch are in normally closed position. If the bin switch and thermo-disc
are closed, replace timer. | | ВЕ
7. With the cuber in the harvest sequence, trip the bin switch or place the toggle switch in the “OFF”
position and back into “ICE” position. Either of these actions should deactivate the timer relay placing
the cuber back in freeze. If proper sequence of all operations is accomplished the timer is in working
order. If not, replace timer.
8. Place toggle switch in “OFF” position. Remove jumper wire from low pressure control. Reset timer dial
to previous position. Test cuber for proper operation. | :
NOTE: If needed the solid state timers can be manually tripped to place the cuber in harvest.
ZN
Timers with H & Hq terminals can be placed in harvest by shorting across H & Hq terminals. This override ;
the timing sequence. Timers without H & Hq terminals, place in harvest by shorting across terminalis 3 & 4
on the timer. This overrides the timer completely.
SAFETY THERMO-DISC Fig. 3
The thermo-disc is a safety control located on the suction line. The control is temperature sensitive and
opens at 70° F + 5° and closes at 40° F + 5° F. The thermo-disc prevents the cuber from overheating. If the
‘bin damper door switch should fail when the ice harvests, the cuber hot 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 |
1. The thermo-disc is a normally open control at 70° F and above, and recloses at 40° F. Closing IS
accomplished by operating the cuber on for approx. 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 № о 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.
3. 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° + 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 that 2-3 minutes. |
Page 22 MANITOWOC ICE CUBERS — C-0600 Series
DAMPER DOOR (BIN) SWITCH Figs. 4 & 5
J ; 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 counter-weight when the harvesting ice falls
through the ice chute.
Check Out Procedure
1. Check free movement of damper door.
2. Check bin switch arm for ON & OFF action, by opening or closing damper door. Switch should open
when the damper door is open approx. 1 to 1-1/2".
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.
LOW PRESSURE CUT-OUT — Fig. 11 item 10
(Used on the C-0690N Models Only)
This is a Robert Shaw low pressure control that opens its contacts on a fall in suction pressure, 2 PSIG, and
closes its contacts on a rise in pressure, 27 PSIG.
The low pressure cut-out is used to start and stop the compressor.
Check-Out Procedure
1. Install a service gage on the suction service valve or port (Fig. 1 Item 11).
2. Placing the toggle switch in the OFF position or holding the damper door open will de- -energize the
Jiquid solenoid valve, Fig. 8, Item 12. The suction side will pump down until the low pressure cut-out
pens its contacts at 2 PSIG. |
3. If the compressor shuts off several pounds above or below this 2 PSIG setting, reset by turning the
adjustment screw clockwise to increase the cut-out point and counter- clockwise to decrease the cut-
out point.
BIN THERMOSTAT CONTROL (Used On CY-0614AS & CY-0615 WS
The bin termostat is used to control ice level in the bin by stopping and starting the cuber. The location of
the sensing bulb will determine the ice level.
The toggle switch on the thermostat housing can be used to jumper out the thermostat. Placing the toggle
switch in the upper position, the thermostat will control the ice level. With the toggle switch in the lower
position, the bin switch (located in the ice chute) will control the ice level.
ALTITUDE EFFECT
The thermostat operating point shifts approximately 3/4° F lower for every 1000 ft. of elevation above sea
level. For altitudes 2000 ft. and above the set point should be calibrated.
RECALIBRATION
Prepare a 32° F ice/water bath. Loosen the set screw and remove the black knob.* Place the thermostat
bulb in the ice bath, rotate the loosened knob clockwise until the contacts just open (32° F). Then turn the
dial counter-clockwise 1/4 turn. The cut-out point should then be at 36° Е. Replace the knob* in such
manner that the built-in “stop” does not allow the knob to turn clockwise to a colder position. Tighten the
set screw.
В — Later models are screw driver instead of knob adjustable and have no “Stop”.

C-0690 CUBER WITH AC-0695A REMOTE CONDENSER
Cuber Model Numbers: CR-O690N
CD-0692N
CY-0694N
Condenser Model Number: AC-0695A
Precharged Line Model Numbers: RT-20, RT-35, RT-50, MRT-28
GENERAL INFORMATION
The cuber head sections listed above are used with the AC-0695A condenser and one of the four
precharged line sets designated by the customer.
Note: The standard C-0600 self-contained cuber is not designed to be used with the AC-O695A remote
condenser.
The CO-0690N Cubers and the AC-0695A Condenser are designed to be used with one of the RT-Line sets.
Manitowoc cannot be responsible for improper operation if lines other than the RT-Sets are used and are of
different diameter or over the 50 ft. maximum length. The precharged lines, cuber head and remote
condenser are all shipped in separate crating.
The ICE making sections of the standard C-0600 and C-0690N Cubers are identical. See Figures 4 & 5 on
pages 8 & 9.
**Cubers used with MRT-28 line set: The MRT-28 line set is a special flexible line to be used in conjunction
with cubers mounted on casters. This special line has an 8 foot section of braided flexible stainless steel to
‘permit the cuber to be moved approximately 4 feet in any direction without damage to the precharged lines.
This provides easy mobility for cleaning & servicing in back of cuber.
INSTALLATION See Fig. 8 For Additional Information
Cuber Set Up:
“Follow the standard cuber instructions on pages 3 through 5, but do not place the cuber into it's final
position until the refrigerant lines and electrical lines to the remote condenser are connected.
- REMOTE AIR CONDENSER SET-UP
1. Assemble two legs to each of the two mounting tracks. This assembly provides for two separate height
adjustments. The standard 12 inch height and a 15 inch height to be used in installations where heavy
snow or debris may collect at base of condenser causing air flow restrictions. See Figure 1.
2. Lacate the remote condenser in a well ventilated area on the roof. Consult the Manitowoc office for
other applications.
3.- Using the six mounting holes provided, secure the remote condenser to the roof. Seal with tar or pitch
to prevent entrance of moisture.
INSTALLING THE REFRIGERATION LINES
1. Each condenser is connected with two precharged lines. The precharged lines are ordered separately
from the condenser to suit each individual application.
The precharged line lengths are 20 ft. (RT-20), 35 ft. (RT-35), 50 ft. (RT-50) and 28 ft. (MRT-28).
Remove the tubing from the carton. Carefully unwind the coil so the tubing doesn’t become kinked.
3. The refrigerant fittings on the cuber and remote condenser are oiled at the factory. Additional lubrica-
tion should be used before assembly. Use Refrigeration Oil Onlyl |
4. Note: The MRT-28 lines are provided with a 90° bend at one end. This end is intended to be attached to
the cuber to provide a minimum 6 inch clearance between cuber and wall. If additional bends are
required, slide armaflex away from tubing. Using a tube bender, carefully bend tubing to required angle.
Page 24 MANITOWOC ICE CUBERS — C-0600 Series
=>. Follow step (6) and connect one refrigerant line to fitting #1 on the cuber, and fitting #1 on the
; condenser. Connect the other line to fitting #2 on both the cuber and condenser. Fig. 9.
6. To connect the refrigerant lines to the cuber, remove the rear & right hand end panels on the cuber.
7. Carefully thread, by hand, the female hose fitting to the male fitting on the cuber and remote
condenser. Using the proper size wrench, tighten the couplings until you feel them bottom out. Then
add an additional % turn to insure proper seal. If a torque wrench is used follow these for %" to 36”
fittings with %-18 thread size, the torque value is 10-12 ft. Ibs. For 1%” fittings with 1-1/16”-12 thread
size, the value is 35-45 ft. Ibs.
Important: Once the refrigerant lines are connected, the seal is broken in the fittings and if removed
from the cuber or remote condenser, the refrigerant charge in the cuber and condenser will be
depleted.

SERVICE NOTE:
To insure proper operation in all ambient conditions, the refrigerant charge in a Manitowoc remote system
must be at nameplate charge. New packages supplied by Manitowoc are precharged. Subsequent repairs to
the sealed system must include a total purge, complete evacuation, and a measured charge. This service
procedure requires connections at three points within the sealed system. |
1. Receiver Service Valve — This evacuates the area between the head pressure control valve and the
solenoids.
2. Suction Side at the Compressor or Low Side Service Port — This evacuates the suction side between
the compressor and solenoid valves. Fig. 11 items 11 & 14.
o. Discharge Side at the High Side Service Port or the Quick Connect Service Port. This evacuates the —
high side between the compressor and the head pressure control.

START-UP
A
MANITOWOC ICE CUBERS — C-0600 Series
à start-up procedure and check list for the remote cubers are the same as for the standard cubers. Pages
4 & 5, with the following additions.
1. Before start-up, open (backseat) the receiver valve.
2. After the cuber is running, check the remote air condenser & verify that the condenser fan is running.
Fan will be off during the defrost cycle.
SYSTEM CONTROL AND SEQUENCE OF OPERATION
The main on-off toggle switch for the cuber is located on the control box. Fig. 4. The toggle switch has three
positions; the center or “off” position, the “water pump” position (only the water pump operates) and the
“ice” position.
SEQUENCE | FREEZE CYCLE
FREEZE CYCLE — Sequence |
Placing the toggle switch in the “ice” position will
energize the liquid line solenoid valve and the
water pump and condenser fan motor through
terminals 4 & 5 on the timer. This will allow the
suction or low side pressure to rise. When the low
side pressure reaches approximately 25 PSIG, the
low pressure cut-out control will close its contacts,
energizing the compressor. The cuber is now in
freeze cycle. As water flows over the evapor-
«Jr, the ice will begin to form.
As the ice cubes form, the suction or low side
pressure will continually decrease. At a present
point the low pressure cut-in control will close its
contacts. 10% PSIG regular and dice cube size and
11 PSIG half dice cube size.
SEQUENCE II FREEZE CYCLE WITH
TIMER ENERGIZED
Sequence ||
Closing of the low pressure cut-in control contacts
will energize the time delay circuit of the solid
state timer through terminal 1. The remaining
freeze time is dependent upon the timer setting.

As the harvest cycle progresses, the hot gas will
warm the evaporator releasing the ice. The ice will
fall through the ice chute, opening the damper
door that is mounted in the chute. (Fig. 4) As the
damper door is pushed open, it will trip the
damper door (bin) micro switch, momentarily de-
energizing the timer and liquid solenoid valve. The
timer relay will return to its normal position, de-
energizing the water pump and condenser fan
motor. The cuber is now in a new freeze cycle.
The ice cuber will continue to cycle in this manner
until the storage bin is full. The ice cuber automat- |
ically discontinues ice production as the ice filis
the chute, holding the damper door and bin micro
switch open.

Opening the bin micro switch or placing the toggle
switch in the “off” position will de-energize the
liquid line solenoid valve. The system will begin to
pump down the low side. When the suction or low
side pressure reaches 2 PSIG, the low pressure
cut-out control will open, de-energizing the com-
pressor.
Within the electrical system there are two safety
controls to protect the cuber, the suction line ther-
modisc and the high pressure cut-out.
И the bin switch would fail when the ice falls
through the ice chute, the cuber would remain in
the harvest cycle until the suction temperature
reached 70% F +5”. At this time the safety thermo-
disc, 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
*armodisc will reclose its contacts at 40% F + 5°.
8 high pressure. cut-out control will shut the
entire cuber off should the condensing or head
pressure become too high.

PEFRIGERATION CYCLE — CO690N Cuber with AC-0695A Remote Condenser (Fig. 10)
eze Cycle
During the freeze cycle the high pressure discharge gas is pumped into the remote condenser. The high
pressure gas is condensed into a high pressure liquid. The high pressure liquid leaves the condenser and
goes through the head pressure control valve to the receiver.
The purpose of the head pressure control valve is to maintain a minimum receiver head pressure of 90-100
PSIG for normal system operation. Because of the pressure drop this minimum pressure will be approxi-
mately 10-15 PSIG higher at the compressor discharge valve.
During colder weather this control will gradually flood the condenser and start by-passing hot gas to the
receiver to maintain the 90-100 PSIG receiver head. An under charge will cause problems during cold
weather (70° F. and below) and will show up in poor defrosting and premature energizing of the low
pressure cut-in.
During hot weather (80° F. and above) the receiver will be V2 to 3% full of liquid refrigerant. An overcharge
can cause problems in hot weather when the refrigerant charge is more than the receiver can hold.
The high pressure liquid leaves the receiver and goes through the heat exchanger reducing the liquid
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 ave. suction pressure will start at approx. 18 PSIG and drop to
approx. 5-7 PSIG when the cuber goes into harvest.
\ |
ARVEST CYCLE
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 approx. 40-
60 PSIG. The head pressure will drop to approx. 70- 100 PSIG.
When the hot gas solenoid valve opens, the head pressure will drop below the 100 PSIG minimum and the
pressure drop across the head pressure control will be over 30 PSIG. This will cause the head pressure
control valve to stop the liquid flow from the condenser and by-pass hot gas to the hot gas solenoid valve.
The cuber goes back into the freeze cycle automatically when the solenoid valve is closed by the harvesting
ice tripping the bin switch.
The cuber is now in a new freeze cycle.
