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.

The AC drive provides thermal overload protection for
the drive motor. However, a separate three-phase circuit
breaker or electrical supply disconnecting device must
be installed for complete electrical overload protection.
This prevents damage to the motor by disconnecting all
legs if one should be lost accidentally. Check the data
plate on the back of the washer-extractor for circuit
breaker requirements.
NOTE: Do NOT use fuses in place of a circuit
breaker.
The washer-extractor should be connected to an
individual branch circuit not shared with lighting or
other equipment.
The connection should be shielded in a liquid-tight or
approved flexible conduit with proper conductors of
correct size installed in accordance with the National
Electric Code or other applicable codes. The
connection must be made by a qualified electrician
using the wiring diagram provided with the washer-
extractor or according to accepted European standards
for equipment labeled with the CE mark.
For personal safety and for proper operation, the
washer-extractor must be grounded in accordance with
state and local codes. If such codes are not available,
grounding must conform with the National Electric
Code, article 250-95 or accepted European standards
for equipment labeled with the CE mark. The ground
connection must be made to a proven earth ground, not
to conduit or water pipes.
If a delta supply system is used, the high leg may be
connected to L3 on the UWPV models.
Mechanical & Electrical Design
Component Function
Keypad
The keypad consists of pressure-sensitive switches
enclosed within the control-module front decal. The
keypad executes all commands and programming
instructions to the computer.
Main Computer Board
The computer board is mounted on the inside front of
the control module and supports the LED display and
indicators. It also provides mounting and printed
circuitry for the ROM, RAM, battery and beeper.
Fuse Board
The fuse board provides mounting for the output fuses,
transformer and R.C. networks for the computer. It is
mounted on a support bracket inside of the control
module.
To reduce the risk of electrical shock, never
touch terminals or components of the AC
drive unless the power is disconnected and
the “CHARGE” indicator LED is off. The AC
drive retains potentially deadly voltage for
some time after the power is disconnected.
Tampering with the AC drive will void the
warranty. There are no user-serviceable
parts inside of the AC drive.
WARNING
To reduce the risk of serious injury, when
using a parameter unit to control the AC
drive, a large sign should be placed on the
front of the machine warning people of the
imminent danger. When controller the AC
drive with a parameter unit, the machine’s
computer and its safety features are
bypassed. This allows the basket to rotate
at high speeds with the door open.
DANGER
Do not use a phase adder on any variable-
speed machine.
