Do not install ice machine in direct sunlight.
1) the ice machine should be installed horizontally;
2) the ambient temperature should be 10~43C(50—110F) and the water inlet
temperature is 1~32 C(33—90F)；
3) For the self-contained ice maker：
Left and right side must have at
least 5cm gap from the wall and the

IV. Operation
1. Checklist before operation
a) Is ice machine level?
b) Are Water inlet and drain hose connected ok?
c) If there are not water lack with the ice machine?
d) Check the power voltage, if it matches the label on the machine?
2. operation
1) Freeze cycle
a) Power plug connection：the control board led is on。
b) startup：Toggle the switch to the on position, the green led will flash; the
hot gas valve open for 10s, the compressor is energized,
c) ice melt： the hot gas valve still keep opening for 20s, then the water
pump running to flush the evaporator for 20s， then close the hot gas
valve and water pump and open the drain valve for 15s then close.
d) prechill（40s）：the compressor is on, and the condenser fan and water
inlet valve are energized, hot gas valve and water pump are closed, thus to
Air inlet
Air outlet

11 / 22
prechill the evaporator.
e) Freeze：water pump is energized to make ice in the evaporator.
2) Harvest cycle
f) energy storage：when the harvest probe doesn’t contact the water，
condenser NTC probe test the liquid tube temperature and give the time to
stop the condenser fan before harvest, to add the heat of the refrigeration
system. Increase the harvest effective.
g) Harvest cycle：hot gas valve is energized to heat the evaporator，when
the surface of ice begin to melt, the ice will drop down by the gravity. And
the ice put the water curtain outside and the magnet switch from close to
open to close, harvest cycle ended to return the prechill cycle and start next
step.
h) Ice full：when the magnet switch opens beyond 30s in harvest cycle, the
ice machine stops, mean the ice is full.

water level position. screw the adjustable nut clockwise, increase the ice
thickness; turn the adjustable nut counterclockwise, and reduce the ice
thickness.

V. Maintenance
Clean and sanitize
Cleaning and Sanitizing GENERAL
You are responsible for maintaining the ice machine in accordance with the instructions in this
manual. Maintenance procedures are not covered by the warranty. Clean and sanitize the ice
machine every three 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.
• Warning
Wear rubber gloves and safety goggles (and/or face shield) when handling Ice Machine
Cleaner or Sanitizer
CLEANING/SANITIZING PROCEDURE
This procedure must be performed a minimum of once every three months.
• The ice machine and bin must be disassembled cleaned and sanitized.
• All ice produced during the cleaning and sanitizing procedures must be discarded.
• Removes mineral deposits from areas or surfaces that are in direct contact with water.
PREVENTATIVE MAINTENANCE CLEANING PROCEDURE
• This procedure cleans all components in the water flow path, and is used to clean the ice machine
between the cleaning/sanitizing procedure.
EXTERIOR CLEANING

13 / 22
Clean the area around the ice machine as often as necessary to maintain cleanliness and efficient
operation.
Wipe surfaces with a damp cloth rinsed in water to remove dust and dirt from the outside of the
ice machine. If a greasy residue persists, use a damp cloth rinsed in a mild dish soap and water
solution. Wipe dry with a clean, soft cloth.
The exterior panels have a clear coating that is stain resistant and easy to clean. Products containing
abrasives will damage the coating and scratch the panels.
• Never use steel wool or abrasive pads for cleaning.
• Never use chlorinated, citrus based or abrasive cleaners on exterior panels and plastic trim pieces.
Cleaning / Sanitizing Procedure
• Warning
Wear rubber gloves and safety goggles (and/or face shield) when handling Ice
Machine Cleaner or Sanitizer.
• 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
• Caution
Never use anything to force ice from the evaporator. Damage may result.
Ice machine cleaner is used to remove lime scale and mineral deposits. Ice machine sanitizer
disinfects and removes algae and slime. For the cleaner and sanitizer, Ecolab company’s
products, Kay Delimer as the cleaner and kay5 as sanitizer are recommend.
NOTE: Although not required and dependant on your installation, removing the ice machine top
cover may allow easier access.
Step 1 Open the front door to access the evaporator compartment. Ice must not be on the
evaporator during the clean/sanitize cycle. Follow one of the methods below:
• Toggle the switch on “off” position at the end of a harvest cycle after ice falls from the
evaporator(s).
• Toggle the switch on “off” position and allow the ice to melt.
Step 2 Remove all ice from the bin/dispenser.
Step 3 To ggle t he s wi tc h on “c le an” p os it i on . Wa ter wil l f lo w through t he w at e r dum p val v e and
down the drain. Wait until the water trough refills (approximately 1 minute), then add the proper
amount of ice machine cleaner.

Step 4 Wait until the clean cycle is complete (approximately *30 minutes). Then disconnect power
to the ice machine (and dispenser when used).
Step 5 Remove parts for cleaning. Please refer to the proper parts removal for your ice machine.

14 / 22
Continue with step 6 when the parts have been removed.
Step 6 Mix the cleaner and lukewarm water. Depending upon the amount of mineral buildup, a
larger quantity of solution may be required. Use the ratio in the table below to mix enough solution
to thoroughly clean all parts.

Step 7 Use the cleaner/water mixture to clean all components. use a soft-bristle nylon brush,
sponge or cloth (NOT a wire brush) to carefully clean the parts. Soak parts for 5 minutes (15 - 20
minutes for heavily scaled parts). Rinse all components with clean water.
Step 8 While components are soaking, use the cleaner/water solution to clean all foodzone
surfaces of the ice machine and bin (or dispenser). Use a nylon brush or cloth to thoroughly clean
the following ice.
• Side walls • Base (area above water trough)
• Evaporator plastic parts - including top, bottom, and sides
• Bin or dispenser Rinse all areas thoroughly with clean water

Step 11 Use the sanitizer/water solution to sanitize all foodzone surfaces of the ice machine and
bin (or dispenser). Use a spray bottle to liberally apply the solution. When sanitizing, pay particular
attention to the following areas:
• Side walls
• Base (area above water trough)
• Evaporator plastic parts - including top, bottom and sides
• Bin or dispense,
Step 12 Wait 20 minutes. Do rinse these surfaces with drinking water after sanitizing.
