Electrical Installation

Input Voltage Requirements
WARNING
Turn off power and water before attempting
any maintenance, repairs, or service, or
before opening any service panel or door.
The washer-extractor is designed for 4-wire, 208-240
Volt, 60 cycle, three-phase service. The control voltage
is 115 Volt.
If a delta supply system is used, the high leg must be
connected to the L3A lead at the J-box.
NOTE: Rotation of the extractor basket should be
clockwise as indicated by the arrow on the lid. To
change direction of extractor rotation, interchange
the L1A and L2A leads.
IMPORTANT: Improper connections will result in
equipment damage and will void the warranty.
Connection Specifications
IMPORTANT: Connection must be made by a
qualified electrician using wiring diagram provided
with machine.

Grounding
For personal safety and proper operation, the machine
must be grounded in accordance with state and local
codes. If such codes are not available, grounding must
conform with National Electric Code, article 250-95.
The ground connection must be to a proven earth
ground at the location service panel and/or to a
grounded metal cold water pipe.
Do not connect the ground to the neutral (white or
blue wire) leg at the J-box. If the machine is intended
for 4-wire service, neutral leg must be provided by
the power company. Do not connect the neutral leg to
the ground wire or green wire.
Use wire size indicated in Electrical Specifications
table for runs up to 50 feet. Use next larger size for
runs of 50 – 100 feet. Use TWO sizes larger for runs
greater than 100 feet. This protects against voltage
drop which would result in a reduction of starting
torque.
Phase Adder
If three-phase service is not available and a Roto-
Phase or other phase adder is used, the artificial leg
must be connected to the L3A lead.
