Sensitive Electronics
ESD problems are present everywhere. ESD may damage or weaken the electronic
control assembly. The new control assembly may appear to work well after repair is
finished, but failure may occur at a later date due to ESD stress.
Use an anti-static wrist strap. Connect wrist strap to green groun connection point or unpainte
metal in the appliance.
- OR -
Touch your finger repeatedly to a green ground connection point or unpainted metal
in the appliance.
Before removing the part from its package, touch the anti-static bag to a green groun connection
point or unpainte metal in the appliance.
Avoi touching electronic parts or terminal contacts; han le electronic control assembly by e ges only.

To ensure safe an secure installation, please observe the instructions below.
Place washer firmly on a stable, even an
soli floor as pro uct installation instructions
escribes in owner’s manual.
Peel protective paper off the tape from the
stacking kit si e bracket.
Fit the stacking kit si e bracket firmly to the
si e of top plate by attaching the ouble-
face tape to top plate as picture shows.
Secure stacking kit si e bracket to the
washer with a screw on the back of bracket.
Repeat Steps 2, 3, 4 for the other si e.
Place the ryer on top of the washer by fitting
legs as shown in the picture. Avoi finger
injuries - be careful not to pinch fingers
between the washer an ryer. Sli e washer
slowly backwar s to the stopper of kit.
Insert the front stacking kit. Push the front
stacking kit back to the stoppers of si e
stacking kit.
Screw both si es of the front kit.
• Do not use stacking kit with a gas ryer in
potentially unstable con itions like a mobile
home.
Stacking kit
Do not attempt installation with one person.
Incorrect installation proce ure can cause
serious acci ents an physical Injuries.
The weight of the ryer an the height of
installation makes the stacking proce ure
too risky for one person. This proce ure
shoul be performe by 2 or more
experience service personnel.

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:
If this type is available at your home. you will be
connecting to a fused disconnect or circuit breaker
box
Important : use 4-wire connection in the places such
as mobile homes and areas where 3-wire connections
is not available.
Prepare minimum 5ft(1.52m) of length in order for
dryer to be replaced.
First, peel 5 inch (12.7cm) of covering material from
end. Make a 5 inch of ground wire bared. After cutting

1
/2inch (3.8cm) from 3 other wires. peel insulation
back 1inch (2.5cm). Make ends of 3 wires a hook
shape.
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.
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.
If this type is available at your home. you will be
connecting to a fused disconnect or circuit breaker
box
1. Connect neutral wire(white) of power cord to center
terminal block screw.
2. Connect red and black wire to the left and right
terminal block screws.
3. Connect ground wire(green) of power cord to external
ground screw and move neutral ground wire of
appliance and connect it to center screw.
4. Make sure that the strain relief screw is tightened.
and be sure that all terminal block nuts are on tight and
power cord is in right position.
