• Preferably a dry and well ventilated area with 60 cm
clearance on both front and rear for ease of mainte-
nance and service should they be required.
• Normal condenser ambient temperature: -28°C to
+50°C. Temperatures not within this operating range
may affect the production capacity of the icemaker.
• The maximum line length for the standard refrigerant
charge is 20 meters.
• The absolute maximum line length is 30 meters and
will require an additional refrigerant charge. Please
contact your nearest Hoshizaki office listed in the
Instruction Manual for guidance.
• The Condenser should not be installed more than 10
metersabove the height of the icemaker or more than
3 meters below it measured from fitting to fitting.
Note: If the recommended guidelines of the installation
are exceeded, the icemaker performance may
be reduced.

1. This icemaker is designed to produce edible
ice. To keep the icemaker sanitary:
•
Wash your hands before removing ice.
• Use the Plastic Scoop provided (acces-
sory).
• Keep the Scoop clean. Clean it by using a
neutral cleaner and rinsing thoroughly.
• The Storage Bin is for ice use only. Do not
store anything else in the Bin.
• ClosetheDoorafterremovingicetoprevent
entrance of dirt, dust or insects into the
Storage Bin.
2. The use of any electrical equipment involves
the observance of some fundamental rules.
In particular:
• Instances of high humidity and moisture
increase the risk of electrical short circuits
andpotential electrical shocks. If in doubt,
disconnect the icemaker.
• Do not use the icemaker when you have
bare feet.
• Do not pull the electricity supply wire in
order to disconnect the icemaker from the
feed network.
• This appliance is not suitable for unsuper-
vised use by young children or aged or
infirm persons.

justments may result in failure.
4. If the unit is turned off, wait for at least 3
minutes before restarting the icemaker to
prevent damage to the Compressor.

The steps in the sequence are as follows:
1) 1 Minute Fill Cycle
Theunitalwaysstartsinthe1minutefillcycle. When
power is applied to the unit, the water valve is ener-
gized and the fill period begins. After 1 minute the
board checks for a closed float switch. If the float
switch is closed the harvest cycle begins. If not,
the unit will not start without adequate water in
thesump. Thisservesalowwatersafetyshutoff. The
water valve will remain energized through additional
1 minute cycles until water enters the sump and the
float switch closes.
2) 1st Harvest Cycle
The compressor starts, hot gas valve opens, water
valve remains open and harvest begins. As the
evaporator warms, the thermistor located on the
suctionlinechecksfora9°Ctemperature. When9°C
is reached, the harvest is turned over to the adjust-
able control board defrost timer which is factory set
fornormal conditions. This adjustmentcanvarythe
defrost timer from 1 to 3 minutes.
3) Freeze Cycle
After the timer terminates the harvest cycle, the hot
gas and water valves close, and the ice production
cycle starts. For the first 5 minutes the controller
board will not accept a signal from the float switch.
This 5 minute minimum freeze acts as a short cycle
protection. At the end of 5 minutes the float switch
