Water Supply Requirements
Water supply requirements:
[]
[]
Valved hot and cold water supply with a water pressure
between 14.5 and 116 PSi (0.1-0.8 MPa).
A hot water heater or boiler supplying an adequate
amount of water between 140-160°F
(60-71 °C). The water
temperature within the washer is controlled to a maximum
temperature that is set in the program. The amount of hot
water required to wash a load of laundry is dependent on
many factors, including the hot and cold water temperature
and the wash program selected. Average amounts of hot
water required to wash one load of laundry are shown in
the table below.

(21°C) cold water supply.

It is also necessary to connect all available water inlets to a
water supply.
Drain Requirements
The washer has a 3" (75 mm) water drain at the back of the
washer. A molded drain hose that extends up to 20" (0.50 m)and
hose clamp are supplied with the washer. To maintain washer
performance,
do not reduce the diameter of the drain pipe.
The washer drain may drain into a waste channel or directly
to a drain.
[]
The waste channel cannot be located under the washer.
There should be at least 4" (100 mm) between the back
of the washer and the middle of the waste channel (see
illustration).
[]
The waste channel must be lower than the drain pipe.
There should be at least a 3/4" (20 mm) air gap between
the bottom of the drain and the water level in the channel.
The drain pipe must be able to handle wastewater from all
of the washers, so the diameter of the drain pipe required is
dependent on the number of washers in the line. Sanitary drains
must be vented and meet all local and municipal codes. The
suggested drain diameter for one to three washers is shown in
the illustration below.

Laundry Product Dispenser Pumps
PN Models
Physical and electrical control connections
for external liquid
laundry product pumps are included in all PN models. If laundry
product dispenser pumps will be used, the pumps should have
an adequate flow rate to deliver the required amount of product
to the dispenser within 30 seconds. Relay supply voltage was set
at the factory. Check your material list for supply voltage.
PD Models
It is also possible to connect external liquid laundry product
pumps to PD model washers, but the following additional
installation steps are required:
[]
It is necessary to complete the physical connection
between
the tubing connector not supplied with PDs, and the
dispenser.
[]
The electrical control connection to the liquid product pumps
is made on the control board.
See page 9, "Laundry Product Supply Pump Connection",
for
additional information.
