Water Supply And Drain Connections - Hoshizaki IM-21CLE Manual De Instrucciones

ENGLISH
* This icemaker must have a separate power supply or receptacle of
220 - 240V.
* The main control box fuse is rated at 5A and should only be replaced
by a qualified service engineer.
* Usually an electrical permit and services of a licensed electrician are
required.
* If the supply cord and the plug should need to be replaced, it should
only be done by a qualified service engineer.
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 fitted.
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 fitted.
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 0A and approved to BS 362.

5. WATER SUPPLY AND DRAIN CONNECTIONS

(For the U.K. only, the connections must be in accordance with current
requirements of the Model Water Byelaws 986 SI No. 47)
* Only potable water should be used for this icemaker.
* Water supply pressure should be minimum 0.5 bar and maximum 8
bar. If the pressure exceeds 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.
* On water-cooled models, a back flow preventer may be required in
the cooling water circuit.
* Water should drain into an open trap.
* The icemaker drain is gravity flow, so ensure drain pipe has an
adequate pitch or fall.
* To prevent a backflow into the Storage Bin, the outlet hose must be
laid as shown in Fig. 3.

1) Attach the angled end of white flexible inlet hose (accessory) onto
the G3/4 fitting on the rear of the icemaker as indicated (Fig. 4),
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 (Fig. 5), noting
washer is correctly positioned before hand tightening as above. It
is a wise precaution to have a stop valve within easy reach.
3) Hand tighten grey flexible outlet hose (accessory) onto the R3/4
fitting on the rear of the icemaker as indicated (Fig. 4), ensuring
rubber sealing washer is correctly positioned to obtain a leak free
joint. The pipe can be cut to length as necessary to suit position of
main drain.
Note: Jointing compounds should be approved and suitable for
potable water use.

* 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. 6 and 7). 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.
