WARNING
SHUT OFF POWER AND WATER BEFORE OPENING ANY SERVICE PANELS.
Dexter single/three-phase 208-240VAC 60 Hz washing machines are intended to be permanently
installed appliances. No power cord is provided. The machine should be connected to an
individual 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.)
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.
