Installation Instructions Section 2
Location of Ice Machine
The location selected for the ice machine must meet the following criteria. If any of these criteria are not met, select another location.
The location must be free of airborne and other contaminants.
The air temperature must be at least 35°F (1.6°C), but must not exceed 110°F (43.4°C).
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.
S0850M Water-Cooled*
Top/Sides 8" (20.3 cm)
Back 5" (12.7 cm)
*There is no minimum clearance required. This value is
recommended for efficient operation and servicing only.
Caution
!
The ice machine must be protected if it will be subjected to temperatures below 32°F (0°C). Failure caused by exposure to freezing temperatures is not covered by the warranty. See “Removal from Service/Winterization”.
Ice Machine Heat of Rejection
Series
Ice Machine
S0850M 12,000 18,000
B.T.U./Hour Because the heat of rejection varies during the ice making cycle,
the figure shown is an average.
Air Conditioning
Heat of Rejection
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 air­cooled ice machines are installed.
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.

Electrical Service
GENERAL
Warning
!
All wiring must conform to local, state and national codes.
VOLTAG E
The maximum allowable voltage variation is ±10% of the rated voltage at ice machine start-up (when the electrical load is highest).
!
Warning
The ice machine must be grounded in accordance with national and local electrical codes.
Important
Observe correct polarity of incoming line voltage.
FUSE/CIRCUIT BREAKER
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).
MINIMUM CIRCUIT AMPACITY
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.)
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.
ELECTRICAL REQUIREMENTS
Refer to Ice Machine Model/Serial Plate for voltage/ amperage specifications.

Section 2 Installation Instructions
Water Supply and Drain Requirements
WATER SUPPLY
Local water conditions may require treatment of the water to inhibit scale formation, filter sediment, and remove chlorine odor and taste.
Important
If you are installing a Manitowoc Arctic Pure water filter system, refer to the Installation Instructions supplied with the filter system for ice making water inlet connections.
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.
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.)
If water pressure exceeds the maximum recommended pressure, obtain a water pressure regulator from your Manitowoc distributor.
Install a water shut-off valve for both the ice making and condenser water lines.
Insulate water inlet lines to prevent condensation.
Caution
!
Do not apply heat to water valve inlet fitting. This will damage plastic valve body.
DRAIN CONNECTIONS
Follow these guidelines when installing drain lines to prevent drain water from flowing back into the ice machine and storage bin:
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.
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.
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.
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.
Water entering the condenser must not exceed 90°F (32.2°C).
Water flow through the condenser must not exceed 5 gallons (19 liters) per minute.
Allow for a pressure drop of 7 psi (48 kPA) between the condenser water inlet and the outlet of the ice machine.
Water exiting the condenser must not exceed 110°F (43.3°C).

Ice Machine Operation Section 3
Sequence Of Operation
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.
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.
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.
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 start­up and then shuts off.
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.
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.
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.
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.)
3-2
Part Number 80-1560-3
Section 3 Ice Machine Operation
HARVEST SEQUENCE
5. Water Purge
The harvest valve(s) opens at the beginning of the water purge to divert hot refrigerant gas into the evaporator.
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.
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
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 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.)
AUTOMATIC SHUT-OFF
7. Automatic Shut-Off
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 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.
SAFETY TIMERS
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 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 de­energizes.
NOTE:
moving the toggle switch to the OFF position, then back to ICE.
The warm water rinse cycle can be terminated by

Ice Machine Operation Section 3
Operational Checks
GENERAL
Manitowoc ice machines are factory-operated and adjusted before shipment. Normally, new installations do 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 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 THICKNESS CHECK
The ice thickness probe is factory-set to maintain the ice bridge thickness at 1/8" (.32 cm).
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" (.32 cm) thick.
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.

HARVEST SEQUENCE 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
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.
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.
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.

Exterior Cleaning
Clean the area around the ice machine as often as necessary to maintain cleanliness and efficient operation.
Water-Cooled Condenser and Water Regulating Valve
Symptoms of restrictions in the condenser water circuit include:
Low ice production
High water consumption
High operating temperatures
High operating pressures
If the ice machine is experiencing any of these symptoms, the water-cooled condenser and water regulating valve may require cleaning due to scale build-up.
Because the cleaning procedures require special pumps and cleaning solutions, qualified maintenance or service personnel must perform them.
AlphaSan
The goal of AlphaSan® is to keep the plastic surfaces of an ice machine cleaner, by reducing or delaying the formation of bio-film. The active ingredient in AlphaSan (Ag+). AlphaSan exchange mechanism. When AlphaSan 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 life of the plastic part. Although AlphaSan does not eliminate the need for periodic cleaning and maintenance. AlphaSan taste of the ice or beverage.
