For electric dryers:
TO MAKE ELECTRICAL CONNECTION FOR U.S. DRYERS
Review electrical requirements on page 6 of these instructions.
IMPORTANT – All U.S. models are produced for a 3-WIRE
SYSTEM CONNECTION. The dryer frame is grounded to the
neutral conductor at the terminal block. A 4-WIRE SYSTEM
CONNECTION is required for new or remodeled construction,
mobile homes, or if local codes do not permit grounding through
neutral. If the 4-wire system is used, the dryer frame cannot be
grounded to the neutral conductor at the terminal block. Refer
to the following instructions for 3- and 4-WIRE SYSTEM
CONNECTIONS.
Remove the terminal block cover plate. (See figure 12.)
Insert the power cord with a U.L. listed strain relief through the
hole provided in the cabinet near the terminal block. Note, a
strain relief must be used.
3-WIRE SYSTEM CONNECTIONS
Do not loosen the nuts already installed on the terminal block.
Be sure they are tight. Use a 3/8 inch deep nut driver.
If the power cord has terminals, place the terminals over the
existing nuts on the posts. The neutral (white or center wire on
power cord) conductor must always be connected to the center
(silver colored) post of the terminal block.
Secure in place using the nuts provided in the parts package.
If the power cord does not have terminals, use the cupped
washers ahead of the nuts.
Be sure the terminal block nuts are tight, but do not overtighten.
Secure the power cord in position. Tighten the strain relief
screw(s) in order to clamp the strain relief to the cord. (See
figure 13.)
Replace the terminal block cover.
BEFORE OPERATING OR TESTING, follow the grounding
directions on page 5.
4-WIRE SYSTEM CONNECTIONS
Remove the ground strap screw from the terminal block
support. Fold the ground strap over so both ends of the ground
strap are attached to the center terminal block post.
Connect the neutral (white) conductor of the cord to the center
(silver) post of the terminal block. Connect the grounding
(green) wire of the cord to the terminal block support using the
ground strap screw.
Connect the red and black wires of the cord to the outer posts
of the terminal block.
Be sure the terminal block nuts are on tight, but do not over-
tighten. Secure the power cord in position. Tighten the strain
relief screw(s) in order to clamp the strain relief to the cord.
(See figure 14.)
Replace the terminal block cover.
WARNING: If converting from 4-wire electrical systems to
3-wire, the ground strap must be reconnected to terminal block
support to ground the dryer frame to the neutral conductor.
