3. INSTALLATION
3.1 SELECT THE BEST LOCATION
1.To prevent vibration and noise, make sure the unit
is installed securely and firmly.
2.Install the unit where the sunlight does not shine
directly on the unit.
3.The outside of the cabinet must extend outward for
at least 11" and there should be no obstacles, such
as a fence or wall, within 20" from the back of the
cabinet because it will prevent heat radiation of the
condenser.
Restriction of outside air will greatly reduce the
cooling efficiency of the air conditioner.
4.Install the unit a little slanted so the back is slightly
lower than the front (about 
1
/
2
"). This will help force
condensed water to the outside.
5.Install the unit from the bottom about 30"~60"
above the floor level.
3.2 CHECK OF INSTALLATION
The setting conditions must be checked prior to
initial starting.
The undermentioned items are especially important
checking points when the installation is finished.
1. Grounding wire (Green or Green and Yellow) is
provided in the power cord. The green wire must
be grounded.
2. Connect to a single-outlet 15A circuit.
3. To avoid vibration or noise, make sure the air
conditioner is installed securely.
4 Avoid placing furniture or draperies in front of the
air inlet and outlet.
3.3. HOW TO DRAIN
(When using drain pipe)
The air conditioner must be installed horizontally or
tilted slightly to the outside for proper water
drainage.
On exceptionally hot and humid days the air
conditioner may overflow condensed water.
If the air conditioner is used in a hot and high
humidity zone, exchange the 
¥L
HOLE RUBBER
for the 
¥M
DRAIN PIPE.(See figure 18, figure 19.)
All side louvers of the cabinet must remain
exposed to the outside of the structure.

3.4 HOW TO INSTALL
SUGGESTED TOOL REQUIREMENTS
PREPARATION OF CHASSIS
1. Before installing the room air conditioner, please
install the knob. (If it is not fixed on the unit.)
2. Remove the screws which fasten the cabinet at
both sides and at the back.
3. Slide the unit from the cabinet by gripping the base
pan handle and pulling forward while 
bracing the cabinet.
4. Slide the air conditioner into the case.
Reinstall the 2 screws removed earlier on each side
of the case.
CAUTION: The power cord must be connected to an independent
circuit. The green wire must be grounded.
5. Stuff the foam between the top of the unit and the
wall to prevent air and insects from getting into the
room.
6. Attach the front grille to the case by inserting the
tabs on the grille into the slots on the front of the
case. Push the grille in until it snaps into place.
When you detach the front grille from the case,
push the grille to your right side and pull it toward
you.
7. Lift the inlet grill and secure the front grille with a
screw. Lower the inlet grille into place.
(In case of some models, you can secure the front grille
from the right side or lower side.)

1. If you want to pull out the filter upward, open the
inlet grille slightly. Turn inside out the front grille.
Disassemble the inlet grille from the front grille
with separating the hinged part by inserting a "—"
type screw-driver tip.
Rotate the inlet grille 180 degrees and insert the
hooks into the lower holes of front grille.
Then, insert the filter (See Figure 27, 28)
2. Attach the front grille to the cabinet by inserting the
tabs on the grille into the tabs on the front of the
cabinet. Push the grille in until it snaps into place.
(See Figue 29)
3. Lift the inlet grille and secure it with a type A screw
through the front grille.
(See Figure 30)
4. If you want to pull out the filter downward, use the
reversible inlet grille without change.
(The grille is already assembled for that way.)
