Electrical Connection

Before continuing with this section, verify the power supply meets the requirements
specified on the washer data plate (serial tag) and in
Requirements. Undercounter and Freestanding Washers should be hard-wired directly
into a junction box.
Verify compliance with all local electrical codes. Unless converting a 230 volt 3-phase
unit to single phase, do not disturb any wiring internal to the washer.
If connecting two legs of a 3-phase power system to obtain single-phase power, consult
a professional to verify all codes/standards are followed. An electrical professional can
determine the appropriate connections for either a Wye or Delta connected power
source.
The supply circuit for the 1.2kW and 2.0kW single phase units must be at least 12 AWG
2-wire grounded cable and must be connected to a dedicated service with a 20 amp
circuit breaker or fuse. Wiring must comply with all local electrical codes. Type THW or
THWN wire may be used if it complies with local codes.
The supply circuit for the 6.0kW 3-phase units require at least 10 AWG 3-wire grounded
cable and must be connected to a dedicated service with 30 amp circuit breakers or
fuses.
If converting the 230 volt 6.0kW 3-phase unit to operate on 230 volt or 208 volt single
phase, a dedicated 40 amp circuit breaker is required with 2 conductor grounded 8
AWG cable. Additional changes to the washer's internal wiring are required. Refer to
the detailed conversion instruction tag secured to the wiring harness behind the front
toe kick or the bottom image in Fig. 4-7 on the following page.
Refer to Figs. 4-6 and 4-7 and follow the steps below to connect the washer to an
appropriate power source.
 Make sure electrical power is turned off.
 Remove the lower toe kick panels on the washer by removing the six screws.
 Remove the electrical box by loosening the two screws on each side of the
washer base and removing the one screw located at the lower center of the box.
 Without disconnecting the existing wiring, carefully pull the electrical box out
enough the gain access to back side.
 Carefully route the electrical supply wire through the strain relief clamp located in
the back center of the base to the strain relief clamp on the back of the electrical
box.
