Section 3 Installation
To reduce the risk of electrical shock, fire, explosion, serious injury or death:
• Disconnect electrical power to the washer-extractor before servicing it.
• Close the gas shut-off valve to the washer-extractor (when applicable) before servicing it.
• Never start the washer-extractor with any guards/panels removed.
• Whenever ground wires are removed during servicing, these ground wires must be
reconnected to ensure that the washer-extractor is properly grounded.

controlled by the computer. The valve configuration is
shown below:
UW35PV – Four 1/2 inch valves
UW60PV – Two 3/4 inch, Two 1/2 inch valves
UW80PV – Four 3/4 inch valves
UW100PV – Four 3/4 inch valves
UW125PV (Designs 1-6) – Four 3/4 inch valves
UW125PV (Design 7) – Two 1 inch, Two 3/4 inch
valves
Drain Valve
The UW35PV uses a motorized 2 inch ball valve, while
the UW60, UW80, UW100 and UW125 use 3 inch ball
valves.
Drain connection sizes are shown below:
Control Module
All electrical controls (e.g., computer board, buzzer,
water level switches and the door lock switch) are
located in a stainless steel enclosure mounted on top of
the shell. It is provided with conduit connections for
safe and reliable connection to the drive motor. The
electrical power source is connected to the power input
terminal strip inside the back of the control module.
AC Drive Control
The AC drive control module provides seven
programmable motor speeds from a single motor. It
lowers inrush current and controls the rate of
acceleration and deceleration. A parameter unit is
available as a troubleshooting aid and to program
changes in the drive control. The AC drive is located
inside of the control module.
AC Drive Interface Board
The AC drive interface board converts motor logic from
the WE-6 computer to the correct signals for the AC
drive. All logic inputs to the computer are routed
through this board.
Door Box
The door box contains the door lock microswitch,
interlock magnetic switch and the door unlock
solenoid.
