III. INSTALLATION AND OPERATING INSTRUCTIONS
WARNING
1. The installation must be carried out by qualied personnel, in accordance
with current regulations, according to the manufacturer’s instructions.
2. Keep ventilation openings, in the appliance enclosure or in the built-in
structure, clear of obstruction.
1. UNPACKING
WARNING
Children should not be allowed in reach of the packaging elements (plastic
bags and expanded polystyrene) as they are potential sources of danger.
CAUTION
Remove shipping carton, tape(s) and packing. If packing material is left in
the ice dispenser, it will not work properly.
1) After removing the packaging, make sure that the ice dispenser is in good condition.
If in doubt, please do not use the equipment but apply to professionally qualified
personnel.

2) Remove shipping tapes holding the package of accessories, and check the contents:
a) Installation Kit
Inlet Hose 1
Outlet Hose 1
Rc1/2-G3/4 Nipple 1
b) Brace 1
c) Machine Screw 2
d) Tapping Screw 2
3) Remove tapes holding the power cord.
2. LOCATION
IMPORTANT
1. This ice dispenser is not intended for outdoor use. Normal operating
ambient temperature should be within 5°C to 40°C. Normal operating
water temperature should be within 5°C to 35°C. Operation of the ice
dispenser, for extended periods, outside of these normal temperature
ranges may affect production capacity.
2. The ice dispenser should not be located next to ovens, grills or other
high heat producing equipment.
3. The location should provide a rm and level foundation for the equipment
at normal counter top height.
4. Allow 15 cm clearance at rear and top and 5 cm at sides for proper
air circulation and ease of maintenance and/or service should they be
required.
5. This appliance is not suitable for installation in an area where a water jet
could be used and where dripping is not allowed.
6. Do not place anything on top of the ice dispenser or in front of the louver.
7. This ice dispenser will not work at subfreezing temperatures. To
prevent damage to the water supply line, drain the ice dispenser
when air temperature is below zero (see “IV. 2. PREPARING THE ICE
DISPENSER FOR LONG STORAGE”).

15
4. ELECTRICAL CONNECTIONS
WARNING
THIS APPLIANCE MUST BE EARTHED
This ice dispenser requires an earth that meets the national and local
electrical code requirements. To prevent possible severe electrical shock to
individuals or extensive damage to equipment, install a proper earth wire
to the ice dispenser. Remove the plug from the mains socket before any
maintenance, repairs or cleaning is undertaken.
* This appliance requires a separate 220 - 240VAC, 13A supply. The electrical supply
must be protected by a suitable circuit breaker.
* The main control box fuse is rated at 5A and should only be replaced by a qualied
service engineer.
* Usually an electrical permit and services of a licensed electrician are required.

Machine Screw
Brace
Fig. 2
Tapping Screw
3. INSTALLATION
* Incorrect installation can cause harm to people, animals or things, for which the
manufacturer cannot be held responsible.
* Secure the ice dispenser to the counter table by using the brace, machine screws and
tapping screws (accessory). See Fig. 2.

16
For the U.K. and the Republic of Ireland only
* The wires in the mains lead are coloured in accordance with the following code:
Green & Yellow = Earth
Blue = Neutral
Brown = Live
As the colours of the wire in the mains lead of this appliance may not correspond with
the coloured markings identifying the terminals in your plug, proceed as follows:
The wire which is coloured Green-and-Yellow must be connected to the terminal in
the plug which is marked with the letter E or by the symbol or coloured Green or
Green-and-Yellow. The wire which is coloured Blue must be connected to the terminal
which is marked with the letter N or coloured Black. The wire which is coloured Brown
must be connected to the terminal which is marked with the letter L or coloured Red.
* Should the socket outlets in the installation site not be suitable for the plug supplied
with your product, the plug must be removed (cut off if it is moulded on plug) and an
appropriate plug tted.
If the non-rewirable plug has been cut from the power supply cord, it must be
disposed of. There should be no attempt to reuse it. Inserting such a plug into a socket
elsewhere presents a serious risk of electrical shock.
* The non-rewirable plug must never be used without a fuse cover being tted.
The correct replacement for the detachable fuse cover is identifiable from the
manufacturer’s reference number stamped on the plug.
Supply of replacement fuse covers can be obtained from Hoshizaki Parts/Service
Centres.
Fuses should be rated at 13A and approved to BS 1362.
* If the supply cord and the plug should need to be replaced, it should only be done by a
qualied service engineer.

17
5. WATER SUPPLY AND DRAIN CONNECTIONS
WARNING
Connect to potable water supply only.
* The connections to the mains water supply
must be made in accordance with the
countries’ current requirements of the Water
Supply or Water Fittings Regulations.
* Water supply pressure should be minimum
0.05 MPa (0.5 bar) and maximum 0.78 MPa
(8 bar). If the pressure exceeds 0.78 MPa (8
bar), use a proper 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.
* The ice dispenser drain is gravity flow, so
ensure drain pipe has an adequate pitch or
fall.
* Water should drain into an open trap.
* Be sure to use the new hose-sets supplied
with the appliance. Do not reuse any old
hose-sets.
1) Attach angled end of white inlet hose
(accessory) to the G3/4 fitting on the
rear of the ice dispenser as indicated
ensuring rubber sealing washer is correctly
positioned. Hand tighten sufficiently to
provide leak free joint.
2) Attach the other end of inlet hose to the
water tap, noting washer is correctly
positioned before hand tightening as
above.
3) By means of a suitable spanner or wrench,
tighten the Rc1/2-G3/4 nipple (accessory)
into the R1/2 tting on the rear of the ice
dispenser as indicated. P.T.F.E. tape and/or
