For the U.K. and the Republic of Ireland Only
• 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.
6. Water Supply and Drain Connections -
See Fig. 3.
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).
• 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 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.
• 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.
