* To avoid performance reduction or malfunction caused by scaling, the
water supply should have a hardness of not more than 50 mg/L and
a silica content of not more than 30 mg/L. Otherwise, installation of a
proper water treatment device will be required.
* Water supply pressure should be minimum 0.07 MPa (0.7 bar) and
maximum 0.8 MPa (8 bar). If the pressure exceeds 0.8 MPa (8 bar),
use a pressure reducing valve. Do NOT throttle back the supply tap.
* A plumbing permit and services of a licensed plumber may be required
in some areas.
* Water should drain into an open trap.
* The icemaker drain is gravity flow, so ensure drain pipe has an
adequate pitch or fall.
* A vented tee connection is required for proper drain flow. See Fig. 7.
* The icemaker drain line must be run separately from the storage bin/
dispenser unit drain line. See Fig. 7.
* There should be no backflow in the water circuit.
* Water supply connection is intended to be made by means of a pipe,
not a hose set.
Note: Jointing compounds should be approved and suitable for potable
water use.
1. OPERATION
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.
2. PREPARING THE ICEMAKER FOR LONG STORAGE
1)
Turn off the circuit breaker.
2) Close the water supply line shut-off valve.
3) Remove all ice from the storage bin/dispenser, and clean the bin/
dispenser.
4) Ask for draining of the icemaker by professional qualified personnel.
III. MAINTENANCE
1. CLEANING
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 clean and sanitise the icemaker
water system at least twice a year and 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.
5. To prevent possible damage, do not clean the plastic parts
with water above 40°C or in a dishwasher.
[1] Machine and Bin 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
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] Storage Bin Interior Cleaning/Sanitisation (Weekly)
1) Open the storage bin door, and remove all ice.
Note: Hoshizaki recommends various types of storage bin for
the icemaker which vary in size and design. The following
instructions are therefore for general guidance only.
2) Wash the bin liner and door inner surface with a neutral non-abrasive
cleaner. Rinse thoroughly with a clean cloth and fresh water.
3) Either mix 5 litres of water with 18 ml of 5.25% sodium hypochlorite
solution in a suitable container or the recommended Hoshizaki
sanitiser as directed.
4) Soak a clean sponge or cloth with the solution, and wipe the bin liner
and door inner surface.
5) Rinse thoroughly with fresh water and a clean cloth to wipe off the
solution. Close the bin door.

II. OPERATING INSTRUCTIONS
WARNING
1. This icemaker is designed to produce edible ice. To keep the
icemaker hygienic:
* Wash your hands before removing ice. Use the plastic scoop
provided (accessory).
* The storage bin is for ice use only. Do not store anything else
in the bin.
* Clean the storage bin before use (see “III. 1. CLEANING”).
* Keep the scoop clean. Clean it by using a neutral cleaner
and rinse thoroughly.
* Close the door after removing ice to prevent entrance of dirt,
dust or insects into the storage bin.
2. All parts are factory-adjusted. Improper adjustments may result
in failure.
3. If the unit is turned off, wait for at least 3 minutes before
restarting the icemaker to prevent damage to the compressor.
