Use the instructions at this section if your home has
a 3-wire receptacle (NEMA type 10-30R) and you
will be using a UL listed, 120/240 volt minimum,
30 amp, dryer power supply cord.
Review the following options to determine the appropriate electrical connection
for your home:
3-wire receptacle
(NEMA type10-30R)
If this type is available at your home. you will be
connecting to a fused disconnect or circuit breaker
box
4 wire direct
Important : The places where a 4-wire connection
is needed are , for example, mobile homes and areas
that local codes do not admit the use of 3-wire
connections.
At least, 5ft(1.52m) of extra length is required in
order for dryer to be able to be moved.
Peel 5 in (12.7cm) of external covering from end
of cable, leaving bare ground wire at 5 in (12.7cm).
Cut 11/2 in. (3.8cm) from 3 remaining wires. Peel
insulation back 1in. (2.5cm). Shape ends of wires
like a hook.
Then, put the hooked shape end of the wire under
the screw of the terminal block(hooked end facing
rightward) and pinch the hook together and screw
tightly.
4-wire connection : Direct wire
Use the instructions at this section if your home has
a 4-wire receptacle (NEMA type 14-30R) and you
will be using a UL listed, 120/240 volt minimum,
30 amp, dryer power supply cord.
