Electrical Connection
Electrical Shock Hazard
Disconnect power before servicing,
Replace all parts and panels before operating.
Failure to do so can result in death or electrical shock.
1. Turn off power at fuse box or breaker box.
2. Insert the cable through the hole in the rear panel, making
sure to use a strain relief. Connect the power cable to the
correct terminal post starting with L1, followed by L2 and--if
present-- L3 and Neutral. The grounding conductor (green-
yellow) should be longer than the phase lines to ensure
it is the last to be disconnected if a cable is pulled out
unintentionally. When using stranded copper conductors,
use "wire end tubes" with an insulated sleeve to avoid
unintentional contact.
3. Remove approximately 6" (150 mm) of shielding from cable
end to expose insulated wires. Be sure that there is sufficient
wire to create a drip loop or wire sag, as shown.
A drip loop or wire sag keeps
condensation from running
into washer
4. Strip wire insulation an adequate
length to make connections. Install
eyelets on ground wires with a
crimping tool.
5. Connect two or three current conducting wires into the
terminal and tighten the screw terminals. Attach ground to
the frame ground bolt as shown in the illustrations and tighten
the locking nut.

POWER SUPPLY TERMINALS
1. Flush water lines to remove debris. Install the rubber washers
in both fitting ends of each inlet hose. Install the non-grooved
fitting nut of the inlet hoses to the hot and cold inlet valves.
Tighten fittings.
2. Attach grooved end of the inlet hoses to the washer. Tighten
fittings.
3. Turn on water and check for leaks in the system.
Drain Connection
1. Cut the pre-formed drain hose so it fits properly on the drain
or in the drain channel.
2. Attach drain hose to washer with clamp provided. If fitted
directly to a drain pipe, use a clamp on the drain pipe as well.
NOTE: Model MFR80 has 2 drain connections.
Laundry Product Supply Pump Connection
Up to 8 laundry product supply pumps may be connected to the
washer. Tubing and relay connections are provided in the back
of the washer.
NOTE: Route hoses and wiring so they will not be pinched,
damaged, or rubbed during use.
Electrical Relay Connection
The electrical connections are relay connections only and do
not provide adequate power for the pumps. The laundry product
supply pumps must be powered by a separate electrical source.
PN Models
1. Turn off power at circuit breaker or fuse box.
2. Remove panel screw and remove cover. Connect relay leads
to numbers 1 through 8. Connect/common ground to lead 10.
3. Replace cover.

PD Models
1. Turn off power at circuit breaker or fuse box.
2. Open top cover. Route control wires through control section
and to relay connector on control board. Connect leads.
NOTE: Support added control wires with wire ties to keep
them away from moving parts. An Insulation Displacement
Connector or 1/4" terminals are needed to connect to the
supply signal on the control board.
Water Supply Connection
Connect the water supply to the washer using the flexible inlet
hoses provided. Do not use a rigid connection for the water
supply.
NOTE: The water connection to the washer requires
a 3/4" British Standard Pipe Thread fitting. The
U
smooth end is a NPT U.S. thread.Threading an NPT
fitting or the NPT end of the inlet hose onto the
washer water inlet threads will damage the fill valve NPTfltting
or the manifold.
