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.
