The installer will normally commission the icemaker to start the
automatic icemaking process. To ensure continuous operation, make
sure that:
* The water supply tap is on,
* The icemaker is plugged into the power supply, and
* The control switch is in the "ICE" position (remove the air filter to
check).

2. PREPARING THE ICEMAKER FOR LONG STORAGE

1) Move the control switch to the "OFF" position.
2) Unplug the icemaker or disconnect the power supply.
3) Close the water supply tap, and remove the inlet hose.
4) Remove all ice from the storage bin, and clean the bin.
5) Disconnect the silicone hose to drain the water from the water tank.
Reconnect the silicone hose back in its correct position after all of
the water has drained. See Fig. 5.

WARNING
1. Before carrying out any cleaning or maintenance operations,
unplug the icemaker from the electrical supply network.
2. Ask a trained service person to check and clean the
condenser at least once a year.
3. This appliance must not be cleaned by use of a water jet.
4. Do not use any alcohol for cleaning/sanitisation of the
icemaker. It may cause cracks on the plastic parts.

[1] Exterior
Wipe the exterior at least once per week with a clean, soft cloth. Use
a damp cloth containing a neutral cleaner to wipe off grease or dirt.
[2] Scoop and Bin Door Grip Cleaning/Sanitisation (Daily)
1) Either mix 3 litres of water with 11 ml of 5.25% sodium hypochlorite
solution in a suitable container, or the recommended Hoshizaki
sanitiser as directed.
2) Soak the scoop in the solution for more than 3 minutes. Rinse
thoroughly, and shake to remove surplus liquid.
Note: Using a cloth to dry may re-contaminate.
3) Use a neutral cleaner to wash the bin door grip. Rinse thoroughly.
4) Soak a clean cloth with the sanitising solution, and wipe the grip.
Use fresh water and a clean cloth to rinse/dry.
[3] Storage Bin Interior Cleaning/Sanitisation (Weekly)
1) Open the storage bin door, and remove all ice.
2) Wash the bin liner with a neutral non-abrasive cleaner. Rinse
thoroughly.
3) Soak a clean cloth with the neutral cleaner, and wipe the door inner
surface. Wipe off the cleaner with a clean damp cloth.
4) Either mix 3 litres of water with 11 ml of 5.25% sodium hypochlorite
solution in a suitable container or the recommended Hoshizaki
sanitiser as directed.
5) Soak a clean sponge or cloth with the solution, and wipe the bin
liner and bin door.
6) Rinse thoroughly with fresh water and a clean cloth to wipe off the
solution. Close the bin door.
Note: Some solutions may cause damage to the bin liner surfaces
or corrosion on the metal parts. Always rinse the sanitiser
unless directed otherwise by Hoshizaki guidelines.
[4] Air Filter
Plastic mesh air filters remove dirt or dust from the air, and keep
the condenser from getting clogged. If the filters get clogged, the
icemaker's performance will be reduced. Remove and clean the air
filters at least twice per month:
1) Remove the air filter.
Note: Do not put your hand inside the machine compartment.
2) Clean the air filter by using a vacuum cleaner. When severely
clogged, use warm water and a neutral cleaner to wash the air
filter.
3) Rinse and dry the air filter thoroughly, and place it in position.
[5] Icemaking Water System
To keep the icemaker hygienic, periodic cleaning of the icemaking
water system is recommended. Always ask a trained service person
to clean the water system.
Note: The user is allowed to move the control switch to the "ICE" or
"OFF" position. Only a qualified service person should move it
to the "WASH" position to flush the icemaking water system.
