**Because the heat of rejection varies during the ice making cycle,
the figure shown is an average.
Ice machines, like other refrigeration equipment, reject
heat through the condenser. It is helpful to know the
amount of heat rejected by the ice machine when sizing
air conditioning equipment where self-co n ta ine d aircooled ice machines are installed.
This information is also necessary when evaluat ing the
benefits of using water-cooled or CVD® Condensing
Units to reduce air conditioning loads. The amount of
heat added to an air-conditioned environment by a
QuietQube® ice machine head section is negligible.

Ice Machine OperationSection 3
Ice Making Sequence of Operation
INITIAL START-UP OR START-UP AFTER
AUTOMATIC SHUT-OFF
1. Water Purge
Before the compressor starts, the water pump and water
dump solenoid are energized for 45 seconds, to
completely purge the ice machine of old water. This
feature ensures that the ice making cycle star ts with
fresh water.
The cool vapor solenoid is also energized during water
purge, although it stays on for an additional 5 seconds
(50 seconds total on time) during the initial refrigeration
system start-up.
2. Refrigeration System Start-Up
Ice Machine Head Section: The liquid line solenoid
valve starts after the 45 second water pur ge, and it
remains on throughout the entire Freeze and Harvest
Sequences. The cool vapor solenoid valve remains on
for 5 seconds during initial compressor start-up and then
shuts off.
The water fill valve is energized at the same time as th e
liquid line solenoid valve.
CVD Condensing Unit: When the refrigerant pressure
is high enough to close the low-pressure control, (after
cool vapor valv e e nergizes in ste p 1) the contactor coil i s
energized and the compressor starts. The compre ssor
and fan cycling control* are supplies with power
throughout the entire Freeze and Harvest Sequences.
When the refrigerant pressure is high enough to close
the fan cycling pres sure control the condenser f an mot or
starts.
FREEZE SEQUENCE
3. Prechill
The compressor is on for 30 seconds prior to water flo w,
to prechill the evaporator. The water fill valve remains on
until the water leve l probe is satisfied.
4. Freeze
The water pump restarts after the 30 second prechill. An
even flow of water is directed across the evaporator and
into each cube cell, where it freezes. The water fill valve
will cycle on and then off one more time to refill the water
trough.
When sufficient ice has formed, the w ater flow (not the
ice) contacts the ice thickness probe. After
approximately 7 seconds of continual water contact, the
harvest sequence is initiated. The ice machine cannot
initiate a harvest sequence until a 6 minute freeze lock
has been surpassed.
Continued on next page …
* The Q0600C ice machine does not use a fan cycling
control. The compressor and the conden ser f an motor
are wired through the contactor. Any time the
contactor coil is energized, these components are
supplied with power.

Part No. 80-1175-3, 6/03
Section 3Ice Machine Operation
HARVEST SEQUENCE
5. Water Purge
The water pump continues to run, and the water dump
valve ener gizes for 45 seconds to pur ge th e water in the
sump trough. The water fill valve energizes (turns on) for
the last 15 seconds of the 45-second water purge.
After the 45 second water purge, the water fill valve,
water pump and dump valve de-energize. (Refer to
“Water Purge Adjust ment” for details.)
The cool vapor solenoid valve also opens at the
beginning of the water purge to d ivert refrigerant gas into
the evaporator.
When the refrigerant pressure is low enou gh to open the
fan cycling pressure control* the condenser fan motor
stops.
* The Q0600C ice machine does not use a fan cycle
control, therefore the condenser fan motor will
continue to run in the harvest cycle.
6. Harvest
The cool vapor solenoid valve remains open and the
refrigerant gas warms the evaporator causing the cubes
to slide, as a sheet, off the evaporator and into the
storage bin. The sliding sheet of cubes s wings the w ater
curtain out, opening the bin switch.
The momentary opening and re-closing of the bin switch
terminates the harvest sequence and returns the ice
machine to the freeze sequence (steps 3- 4).
AUTOMATIC SHUT-OFF
7. Automatic Shut-Off
Ice Machine Section: When the storage bin is f ull at the
end of a harvest sequence, the sheet of cubes fails to
clear the water curtain and will hold it open. After the
water curtain is held open for 7 seconds, the ice
machine shuts off. The ice machine remains off for 3
minutes before it can automatically restart.
CVD Condensing Unit: The liquid line solenoid valve
closes, allowing the refrigeration system to pump down.
when the refrigerant pressure is low enough to ope n the
fan cycling pressure control* the condenser fan motor
stops. When the refrigerant pressure is low enough to
open the low pressure control, the contactor coil is deenergized and the compressor stops.
The ice machine remains off until enough ice has been
removed from the storage bin to allow the ice to fall clear
of the water curtain. As the water curtain swings back to
the operating position, the bin switch re-closes and the
ice machine restarts (steps 1 - 2), provided the 3 minute
delay period is complete.
* The Q0600C ice machine does not use a fan cycle
control, therefore the condenser fan motor will
energize and de-energize with the compressor.

Operational Checks
GENERAL
Manitowoc ice machines are factory-operated and
adjusted before shipment. Normally , a ne wly installed ice
machine does not require any adjustment.
To ensure proper operation, always follow the
Operational Checks:
•when starting the ice machine for the first time
•after a prolonged out of service period
•after cleaning and sanitizing
NOTE: Routine adjustments and maintenance
procedures outlined in this manual are not covered by
the warranty.
WATER LEVEL
The water level sensor is set to maintain the proper
water level above the water pump housing. The water
level is not adjustable.
If the water level is incorrect, check the water le v el probe
for damage (probe bent, etc.). Repair or replace the
probe as necessary.
ICE THICKNESS CHECK
After a harvest cycle, inspect the ice cubes in the ice
storage bin. The ice thickness probe is factory-set to
maintain the ice bridge thickness at 1/8" (3.2 mm).
NOTE: Make sure the water curtain is in place when
performing this check. It prevents water from splashing
out of the water trough.
1. Inspect the bridge connecting the cubes. It should
be about 1/8" (3.2 mm) thick.
2. If adjustment is necessary, turn the ice thickness
probe adjustment screw clockwise to increase
bridge thickness, counterclockwise to decrease
bridge thickness.
NOTE: Turning the adjustment 1/3 of a turn will change
the ice thickness about 1/16" (1.5 mm).

HARVEST SEQUENCE WATER PURGE
The harvest sequence water purge ad justment ma y o nly
be used when the ice machine is hooked up to special
water systems, such as a de-ionized water treatment
system.
Important
The harvest sequence water purge is factor y-set at
45 seconds. A shorter purge setting (with standard
water supplies such as city water) is not
recommended. This can increase water system
cleaning and sanitizing requirements.
•The harvest sequence water pu rge may be set to 15,
30, or 45 seconds.
•During the harvest sequence water purge, the water
fill valve energize s and de-energizes by time. The
water purge must be at the factory setting of 45
seconds for the water fill valve to energize during the
last 15 seconds of the water purge. If it is set to less
than 45 seconds, the water fill valve will not energize
during the water purge.

MANITOWOC’S PATENTED CLEANING OR
SANITIZING TECHNOLOGY
Manitowoc Ice Machines include technology that allows
the initiation and completion of a cleaning or sa nitizing
cycle at the flip of a switch. This cycle will permit
cleaning or sanitizing of all surf aces that come in contact
with the water distribution system. Periodic maintenance
must be performed that includes sanitizing the bin (or
dispenser) and adjacent surf ace are as , which cannot be
contacted by the water distribution system.
This technology will also allow initiation and completion
of a clean or sanitize cycle, after which the ice machine
automatically starts ice making again.
Refer to the cleaning or sanitizing procedure for
complete details.
The AuCS Accessory can be set to automatically start
and finish a clean or sanitize cycle every 2, 4, or 12
weeks. This accessory monitors ice-making cycles and
initiates a cleaning or sanitizing cycle automatically.
Refer to Automatic Cleaning System (AuCS) Accessory
for further details.
ALPHASAN
The goal of AlphaSan is to keep the plastic surfaces of
an ice machine cleaner, by reducing or delaying the
formation of biofilm. The active ingredient in AlphaSan
is the element silver in the form of silver ions (Ag+).
AlphaSan slowly releases silver ions via an ion
exchange mechanism. When AlphaSan is compounded
directly into a plastic part, a controlled release of silver
ions from the surface is regulated to maintain an
effective concentration at or near the surface of the
plastic ice machine part.
AlphaSan’s unique ability to effectively control the
release of silver not only protects against undesired
discoloration of the plastic, but also will last the lif e of the
plastic part. Although AlphaSan helps prevent biofilm
build up it does not eliminate the need for periodic
cleaning and maintenance. AlphaSan has no adverse
effect on the taste of the ice or beverage.
