HOW THE MACHINE MAKES ICE
Turn the power switch to the ON position. Then
press ON/OFF button in front panel The LCD
screen lights After about 3 minutes the machine
will automatically go into the ice-making stage
There
are two distinct cycles: Freeze and
Harvest. During the Freeze cycle, water ows
to the evaporator surface In the Harvest
cycle, the ice is released and water enters the
machine A complete cycle can take 15 to 40
minutes, depending on ambient temperature
and operating conditions
Freeze: During the Freeze cycle the compr
essor is pumping refrigerant, the fan motor is blowing air, and
the water pump is circulating water When the batch of ice
has been fully formed, the ice maker stops the
Freeze cycle and begins the Harvest cycle
Harvest: During the Harvest cycle the compressor is still operating, power is supplied to the water pur
ge
valve and hot gas valve The water purge valve opens and allows the water pump to purge the water
remaining in the water tank, r
emoving all impurities and sediment
This allows the machine to make clear
ice cubes and keep mineral build-up at a minimum Then the water pump stopped The hot gas valve
opens, diverting hot refrigerant gas into the evaporator The gas warms the evaporator
, causing the cubes
to slide as a unit off the evaporator and into the storage bin The Freeze cycle will r
estart when all the cubes
drop into the bin
HOW THE MACHINE USES WATER:
The ice
cube machine begins with a xed charge of water that is contained in the water tank. As the water
ows to the freezing evaporator surface, the water will freeze and stick to the ice cube molds. During the
ice-making process, fresh water enters the water tank continuously as the water from the trough freezes
continuously on the evaporator
NORMAL SOUNDS
Your new ice cube machine may make sounds that ar
e unfamiliar to you
Most of the new sounds are
normal.
Hard surfaces like the oor and walls can amplify the sounds. The following describes the kinds of
sounds that might be new to you and what may be causing them
• Rattling noises
may come from the ow of the refrigerant or the water line. Items stored on top of the ice
cube machine can also make noises
• The high-efciency compressor may make a pulsating or high-pitched sound.
• Running water may make a splashing sound
• Y
ou may hear air being for
ced over the condenser by the condenser fan
• During the Harvest cycle, you may hear the sound of ice cubes falling into the ice storage bin
PREPARING THE ICE CUBE MACHINE FOR LONG STORAGE
If the ice cube machine will not be used for a long time, or it is to be moved to another place, it will be
necessary to drain the system of water
1 Shut off the water supply at the main water sour
ce
2 Disconnect the water supply line from the water inlet
3 Shut off the power supply at the main electrical power sour
ce
4. MIM150N(H)/200N(H)/260N(H): Screw off the water tank screw nut and drain out water completely,
tighten the nut after fnishing. Dry the tank.
5 Remove the ice from the ice storage bin Dry the bin
6 Leave the door open to allow for circulation and to pr
event mold and mildew
7 Leave the water supply line and power cord disconnected until r
eady to reuse

maintenance will ensure efciency, top performance, and long life. The
maintenance intervals listed ar
e based on nor
mal conditions Y
ou may want to shorten the intervals if
you have pets or there ar
e other special considerations
WHAT SHOULDN’T BE DONE
Never keep anything in the ice storage bin other than ice: objects like wine and beer bottles ar
e not
only unsanitary, but the labels may slip of
f and plug up the drain
WHAT SHOULD BE KEPT CLEAN
There ar
