Water Supply And Drain Connections - Hoshizaki KM-280MAH-E Manual De Instalación

ENGLISH
As the colours of the wires in the power cord 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
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.
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 13A and approved to BS
1362.

WARNING WARNING WARNING WARNING WARNING
To prevent damage to the pump assembly, do not
operate the icemaker when the water supply is OFF,
or if the pressure is below .7 bar. Do not run the
icemaker until the proper water pressure is reached.
• Only potable water should be used for the icemaker
supply.
• Connection to the water services should be done by a
professionally qualified person.
• Water supply inlet is 1/2" female pipe thread (FPT).
Note: On water-cooled models, two water supply
inlets are provided. One is for the icemaker,
and the other is for the water-cooled
condenser. Connecting potable water to the
Condenser will not affect performance but
may result in high use/waste.
• A water supply line shut-off valve and drain valve should
be installed. A ball valve is recommended for the shut-
off valve. A type of valve other than a ball valve should
not have a minimum opening smaller than the water
supply line ID as this can cause a reduced water flow
rate which can lead to poor defrost performance and/
or freeze up. A minimum of 13 mm. OD copper tubing
or is recommended for the water supply lines.
• Water supply pressure should be a minimum of .7 bar
and a maximum of 8 bar. If the pressure exceeds 8
bar, the use of a pressure reducing valve is required.
Do NOT throttle back the supply tap.
• Drain outlet for icemaker dump and storage bin is 3/4"
FPT. The drain for condensation is a 10 mm. ID pipe.
The icemaker drain and the condenser drain piping
connections must be made separately from the bin
drain. The sump drain should be vented to insure an
adequate flow rate during the harvest cycle. (See Fig.
3).
Note: On water-cooled models, a 3/8" FPT is
provided for the condenser drain outlet.
• Do NOT use solder type fittings as the application of
heat to the icemaker/bin may result in damage to the
internal connections.
• The drains must have 2 cm. fall per 30 cm. on horizontal
runs to get a good flow.
• The drains should not be piped directly to the sewer
system. An air gap of a minimum of 5 vertical cm.
should be between the end of the drain pipe from the
icemaker or the ice bin and the floor drain. (See Fig. 3).
• This icemaker should be installed in accordance with
applicable national, provincial and local regulations.
• In some areas, a back flow preventer may be required
in the cooling water circuit.
