5. WATER SUPPLY AND DRAIN CONNECTIONS
WARNING
To prevent damage to the freezer mechanism, do not operate this icemaker
when the water supply is OFF, or if the pressure is below 10 PSIG (0.7 bar), the
recommended water pressure. Stop the icemaker until proper water pressure
is resumed.
CAUTION
1. A brass fitting for the water supply line connection is attached to the 3/4” BSP
plastic threads to avoid cross-threading of the Water Valve possibly resulting
in leaks. The brass fitting allows connection of a 1/2” FPT that should be
connected to the potable water supply line.
2. While making the water supply line connection, use a wrench to hold the
brass fitting still to prevent overtightening and damage to the plastic threads.
* Water supply inlet for the icemaker is 1/2” female pipe thread (FPT).
Note: On water-cooled model, two water supply inlets are provided. One is for the icemaker
(1/2” FPT), and the other is for the water-cooled condenser (1/2” FPT).
* The brass fitting is attached as shown in Fig. 4. The fitting size is a 1/2” FPT and must be
connected only to a potable water supply.
* A water supply line shut-off valve and drain valve must be installed.
* Water supply pressure should be a minimum of 10 PSIG (0.7 bar) and a maximum of 113
PSIG (7.5 bar). If the pressure exceeds 113 PSIG (7.5 bar), use a pressure reducing valve.
* Drain outlet for icemaker dump is 3/4” FPT.
Note: On water-cooled model, a 3/8” FPT is provided for the condenser drain outlet. The
icemaker drain and the condenser drain piping connections must be made separately.
* Drain must be 1/4” fall per foot (2 cm fall per meter) on horizontal runs to get good flow.
* Keep a more than 2 vertical inch (5 vertical cm) air gap between the drain pipe end and the
sink.
* The drain pipe must be so laid as to prevent a backflow into the Storage Bin. Provide a trap
in the bin drain line to prevent odor from flowing back into the Storage Bin.
