Separate hot and cold water lines must be provided, maintaining 30 psi to 120 psi (207 kPa to 818
kPa) water flow pressure. A 140F (60C) degree hot water supply is recommended for best washing
results.

branch circuit not shared by lighting or other equipment. The connection should be sheathed in
liquid tight flexible conduit, or equivalent, with conductors of the proper size and insulation. A
qualified technician should make such connections in accordance with the wiring diagram. (Suggest
a minimum wire size of 12 ga.) (Suggest a minimum wire size of 10 ga.for Single Phase operation)
TO MAKE ELECTRICAL CONNECTIONS: Disconnect all power to the washer. Remove screw
and lift out the cover located in the upper left corner of the machine (as viewed from the back).
If power is 208-240-3PH-60Hz, connect L1, L2, L3 and ground. If there is a high leg it must
be connected to L3.
If power is 208-240-1PH-60Hz, connect L1, L2 and Ground.
NOTE: It is important that the grounding screw next to the power terminal block TB-1 be
connected to a good external ground.
