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 a 1/2" 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 con-
denser. 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 perfor-
mance 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.
• The drain outlets for the icemaker sump and storage
bin are 3/4" FPT. The icemaker drain and the con-
denser 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. 2).
• Do NOT use solder type fittings as the application of
heat to the icemaker/bin may result in damage to the
internal connections.
Note: On water-cooled models, a 1/2" FPT is
provided for the condenser drain outlet.
• The drains must have 2 cm. fall per 30 cm. on horizon-
tal 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.
2).
• 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.
