5. ELECTRICAL CONNECTIONS
WARNING
THIS APPLIANCE MUST BE EARTHED
This icemaker 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 icemaker. 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.
* Stacked icemakers should each have a separate receptacle, but
they must all be connected in parallel to the same single phase
supply or circuit with sufcient ampacity. In addition and to avoid
nuisance tripping, individual circuit breakers for each machine
should not be used.
* 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.
* If the supply cord is damaged, it must be replaced by a special cord
or assembly available from the manufacturer or its service agent.
* In accordance with the requirement of the IEC standard, the
maximum permissible system impedance (Zmax) at the interface
point of the power supply to be connected with this icemaker must
be 0.23+j0.23 ohm. Determine in consultation with the supply
authority, if necessary, that the icemaker is connected only to a
supply of 0.23+j0.23 ohm or less.
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:
Plastic Clamp
Lower Unit
Receptacle
Upper Unit
Plug
Wiring Channel
Fig. 10
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identiable
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.
6. WATER SUPPLY AND DRAIN CONNECTIONS
* 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.
* Only potable water should be used for the icemaker.
* Water supply pressure should be minimum 0.05 MPa (0.5 bar) and
maximum 0.78 MPa (7.8 bar). If the pressure exceeds 0.78 MPa (7.8
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 icemaker drain is gravity flow, so ensure drain pipe has an
adequate pitch or fall.
* Water should drain into an open trap.
* Leave a vertical air gap of at least twice the drain pipe diameter
between the end of the drain pipe and the top of the open trap.
* PreventabackowintotheStorageBin.
* Onwater-cooledmodel,a back owpreventermay be requiredin

[Water-Cooled Model]
* Hoshizaki recommends that the water-cooled Condenser should
be connected to a closed circuit recirculating type cooling system
utilizing a tower, water chiller or similar (see Fig. 15 and 16). Water
make up should be via a ball valve/break tank arrangement.
* Whilst connecting a water-cooled Condenser to a mains water
(potable) supply will not affect the performance of the machine, it will
most certainly cause a high use/waste of a valuable resource and is
not recommended.
* The services of a licensed or coded plumber should be used to
ensure a correct installation.
* The connections should be made properly in compliance with the
applicable national or local regulations.
[a] Standard connections according to WRAS regulations in U.K.
(Fig. 15 and 16)
* When selecting a Cooling Tower, refer to the following peak values
ofheatowintheCondenser:
Model IM-240DW/XW: 5235 W
* Pipes between the Cooling Tower and the icemaker should be at
least 20 mm DIA to reduce pressure loss, even though the icemaker
ttingsare13mmDIA.
* Pressure loss in the water circuit inside the unit will be 5 to 6 m
whenthecoolingwaterowsattheratioof4to5lit/min.
* SelectaCirculatingPumpreferringtotheabovevaluesofheatow.
* Do not use a Cascade Pump, or the Water Regulator will vary the
owandstopitduringthedefrostcycle.
* The Strainer must be cleaned periodically.
