Location of Ice Machine  
Section 2  
Ice Machine Heat of Rejection  
The location selected for the ice machine must meet the  
following criteria. If any of these criteria are not met,  
select another location.  
Heat of Rejection  
Series  
Ice Machine  
Air Conditioning  
Peak  
S0850M  
12,000  
18,000  
The location must be free of airborne and other  
contaminants.  
B.T.U./Hour  
Because the heat of rejection varies during the ice making cycle,  
the figure shown is an average.  
The air temperature must be at least 35°F (1.6°C),  
but must not exceed 110°F (43.4°C).  
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-contained air-  
cooled ice machines are installed.  
The location must not be near heat-generating  
equipment or in direct sunlight.  
The location must not obstruct air flow through or  
around the ice machine. Refer to the chart below for  
clearance requirements.  
This information is also necessary when evaluating the  
benefits of using water-cooled or remote condensers to  
reduce air conditioning loads. The amount of heat added  
to an air conditioned environment by an ice machine  
using a water-cooled or remote condenser is negligible.

Knowing the amount of heat rejected is also important  
when sizing a cooling tower for a water-cooled  
condenser. Use the peak figure for sizing the cooling  
tower.  
*There is no minimum clearance required. This value is  
recommended for efficient operation and servicing only.

FUSE/CIRCUIT BREAKER  
Electrical Service  
A separate fuse/circuit breaker must be provided for  
each ice machine. Circuit breakers must be H.A.C.R.  
rated (does not apply in Canada).  
GENERAL  
!
Warning  
MINIMUM CIRCUIT AMPACITY  
All wiring must conform to local, state and national  
codes.  
The minimum circuit ampacity is used to help select the  
wire size of the electrical supply. (Minimum circuit  
ampacity is not the ice machine’s running amp load.)  
VOLTAGE  
The wire size (or gauge) is also dependent upon  
location, materials used, length of run, etc., so it must be  
determined by a qualified electrician.  
The maximum allowable voltage variation is ±10% of the  
rated voltage at ice machine start-up (when the electrical  
load is highest).  
ELECTRICAL REQUIREMENTS

Installation Instructions  
DRAIN CONNECTIONS  
Water Supply and Drain Requirements  
Follow these guidelines when installing drain lines to  
prevent drain water from flowing back into the ice  
machine and storage bin:  
WATER SUPPLY  
Local water conditions may require treatment of the  
water to inhibit scale formation, filter sediment, and  
remove chlorine odor and taste.  
Drain lines must have a 1.5 inch drop per 5 feet of  
run (2.5 cm per meter), and must not create traps.  
The floor drain must be large enough to  
accommodate drainage from all drains.  
Important  
If you are installing a Manitowoc Arctic Purewater  
filter system, refer to the Installation Instructions  
supplied with the filter system for ice making water  
inlet connections.  
Run separate bin and ice machine drain lines.  
Insulate them to prevent condensation.  
Vent the bin and ice machine drain to the  
atmosphere. Do not vent the condenser drain on  
water-cooled models.  
AIR GAP  
An air gap is incorporated into the design of the ice  
machine. Maximum water level is the top of the water  
trough, which allows a minimum 1 inch air gap.  
Cooling Tower Applications  
(Water-Cooled Models)  
A water cooling tower installation does not require  
modification of the ice machine. The water regulator  
valve for the condenser continues to control the  
refrigeration discharge pressure.  
WATER INLET LINES  
Follow these guidelines to install water inlet lines:  
Do not connect the ice machine to a hot water  
supply. Be sure all hot water restrictors installed for  
other equipment are working. (Check valves on sink  
faucets, dishwashers, etc.)  
It is necessary to know the amount of heat rejection, and  
the pressure drop through the condenser and water  
valves (inlet and outlet) when using a cooling tower on  
an ice machine.  
If water pressure exceeds the maximum  
recommended pressure, obtain a water pressure  
regulator from your Manitowoc distributor.  
Water entering the condenser must not exceed 90°F  
(32.2°C).  
Install a water shut-off valve for both the ice making  
and condenser water lines.  
Water flow through the condenser must not exceed 5  
gallons (19 liters) per minute.  
Insulate water inlet lines to prevent condensation.  
Allow for a pressure drop of 7 psi (48 kPA) between  
the condenser water inlet and the outlet of the ice  
machine.  
Caution  
!
Do not apply heat to water valve inlet fitting. This will  
damage plastic valve body.  
Water exiting the condenser must not exceed 110°F  
(43.3°C).

Ice Machine Operation  
Sequence Of Operation  
Section 3  
NOTE: The toggle switch must be in the ice position and  
the water curtain must be in place on the evaporator  
before the ice machine will start.  
FREEZE SEQUENCE  
3. Prechill  
The compressor is on for 30 seconds (60 seconds initial  
cycle) prior to water flow, to prechill the evaporator. The  
water fill valve remains on until the water level probe is  
satisfied.  
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 starts with  
fresh water.  
4. Freeze  
The water pump restarts after the 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.  
The harvest valve(s) 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.  
When sufficient ice has formed, the water flow (not the  
ice) contacts the ice thickness probe. After  
approximately 10 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.  
2. Refrigeration System Start-Up  
The compressor starts after the 45 second water purge,  
and it remains on throughout the entire Freeze and  
Harvest Sequences. The water fill valve is energized at  
the same time as the compressor. The harvest valve(s)  
remains on for 5 seconds during initial compressor start-  
up and then shuts off.  
At the same time the compressor starts, the condenser  
fan motor (air-cooled models) is supplied with power  
throughout the entire Freeze and Harvest Sequences.  
The fan motor is wired through a fan cycle pressure  
control, therefore it may cycle on and off. (The  
compressor and condenser fan motor are wired through  
the contactor. As a result, anytime the contactor coil is  
energized, the compressor and fan motor are supplied  
with power.)

Section 3  
Ice Machine Operation  
HARVEST SEQUENCE  
5. Water Purge  
AUTOMATIC SHUT-OFF  
7. Automatic Shut-Off  
The harvest valve(s) opens at the beginning of the water  
purge to divert hot refrigerant gas into the evaporator.  
When the storage bin is full 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 30 seconds, the ice machine shuts off. The  
ice machine remains off for 3 minutes before it can  
automatically restart.  
The water pump continues to run, and the water dump  
valve energizes for 45 seconds to purge the water in the  
sump trough. The water fill valve energizes (turns on)  
and de-energizes (turns off) strictly by time. The water fill  
valve energizes for the last 15 seconds of the 45-second  
water purge.  
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.  
After the 45 second water purge, the water fill valve,  
water pump and dump valve de-energize. (Refer to  
“Water Purge Adjustment” for details.)  
6. Harvest  
SAFETY TIMERS  
The harvest valve(s) 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 swings the water curtain out,  
opening the bin switch.  
The control board has the following non-adjustable  
safety timers:  
The ice machine is locked into the freeze cycle for 6  
minutes before a harvest cycle can be initiated.  
The momentary opening and re-closing of the bin switch  
terminates the harvest sequence and returns the ice  
machine to the freeze sequence (Step 3 - 4.)  
The maximum freeze time is 60 minutes at which  
time the control board automatically initiates a  
harvest sequence (steps 5 & 6).  
The maximum harvest time is 3.5 minutes at which  
time the control board automatically initiates a freeze  
sequence (steps 3 & 4).  
WARM WATER RINSE CYCLE  
Closing the back of the evaporator allows ice to build up  
on the rear of the evaporator and the plastic evaporator  
frame parts. After 200 freeze/harvest cycles have been  
complete the control board will initiate a warm water  
rinse.  
After the 200th harvest cycle ends:  
The Clean and Harvest LED’s energize to indicate  
the ice machine is in a warm water rinse.  
The compressor and harvest valve remain  
energized.  
The water pump energizes.  
The water inlet valve energizes until water contacts  
the water level probe.  
The compressor and harvest valve warm the water  
for 5 minutes, then de-energize.  
The water pump remains energized for an additional  
5 minutes (10 minute total on time) then de-  
energizes.  
NOTE: The warm water rinse cycle can be terminated by  
moving the toggle switch to the OFF position, then back to ICE.

ICE THICKNESS CHECK  
Operational Checks  
The ice thickness probe is factory-set to maintain the ice  
bridge thickness at 1/8" (.32 cm).  
GENERAL  
Manitowoc ice machines are factory-operated and  
adjusted before shipment. Normally, new installations do  
not require any adjustment.  
NOTE: Make sure the water curtain is in place when  
performing this check. It prevents water from splashing  
out of the water trough.  
To ensure proper operation, always follow the  
Operational Checks:  
1. Inspect the bridge connecting the cubes. It should  
be about 1/8" (.32 cm) thick.  
when starting the ice machine for the first time  
after a prolonged out of service period  
after cleaning and sanitizing  
2. If adjustment is necessary, turn the ice thickness  
probe adjustment screw clockwise to increase  
bridge thickness, counterclockwise to decrease  
bridge thickness. Set 1/4” gap between ice machine  
and evaporator as a starting point, then adjust to  
achieve a 1/8” bridge thickness.  
NOTE: Routine adjustments and maintenance  
procedures 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 level probe for damage (probe bent,  
etc.). Repair or replace the probe as necessary.

Ice Machine Operation  
HARVEST SEQUENCE WATER PURGE  
During the harvest sequence water purge, the water  
fill valve energizes 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.  
The harvest sequence water purge adjustment may be  
used when the ice machine is hooked up to special  
water systems, such as a de-ionized water treatment  
system.  
!
Warning  
Disconnect electric power to the ice machine at the  
electrical disconnect before proceeding.  
Important  
45 second  
setting  
The harvest sequence water purge is factory-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.  
0 second  
setting  
The harvest sequence water purge is factory set for  
45 seconds. Repositioning the jumper will set the  
harvest water purge to 0 seconds. This setting does  
not affect the SeCs or AuCs (cleaning) sequences.

Caution  
!
GENERAL  
Never use anything to force ice from the evaporator.  
Damage may result.  
Clean and sanitize the ice machine every six months for  
efficient operation. If the ice machine requires more  
frequent cleaning and sanitizing, consult a qualified  
service company to test the water quality and  
recommend appropriate water treatment. An extremely  
dirty ice machine must be taken apart for cleaning and  
sanitizing.  
Step 3 Remove all ice from the bin.  
Step 4 To start cleaning, place the toggle switch in the  
CLEAN position. The water will flow through the water  
dump valve and down the drain. The Clean light will turn  
on to indicate the ice machine is in the Cleaning mode.  
Step 5 Wait about two minutes or until water starts to  
flow over the evaporator.  
Caution  
!
Use only Manitowoc approved Ice Machine Cleaner  
(part number 94-0546-3) and Sanitizer (part number  
94-0565-3). It is a violation of Federal law to use  
these solutions in a manner inconsistent with their  
labeling. Read and understand all labels printed on  
bottles before use.  
Step 6 Add the proper amount of Manitowoc Ice  
Machine Cleaner to the water trough by pouring  
between the water curtain and evaporator.

CLEANING PROCEDURE  
Step 7 The ice machine will automatically time out a  
ten minute cleaning cycle, followed by six rinse cycles,  
and stop. The Clean light will turn off to indicate the  
Cleaning cycle is completed. This entire cycle lasts  
approximately 30 minutes.  
Caution  
!
Do not mix Cleaner and Sanitizer solutions together.  
It is a violation of Federal law to use these solutions  
in a manner inconsistent with their labeling.  
Step 8 When the cleaning process stops, move the  
toggle switch to OFF position. Refer to “Sanitizing  
Procedure” on the next page.

Warning  
Wear rubber gloves and safety goggles (and/or face  
shield) when handling ice machine Cleaner or  
Sanitizer.  
Step 9  
A. The ice machine may be set to start and finish a  
self-cleaning procedure then automatically start  
ice making again.  
Ice machine cleaner is used to remove lime scale or  
other mineral deposits. It is not used to remove algae or  
slime. Refer to the section on Sanitizing for removal of  
algae and slime.  
B. You must wait about one minute into the  
cleaning cycle (until water starts to flow over the  
evaporator) then move the switch from CLEAN
