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 12" 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.
CAUTION
All side louvers of the cabinet must remain
exposed to the outside of the structure.
4.Install the unit a little slanted so the back is slightly
lower than the front (about '/7"). This will help force
con-densed 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.
(or 20A circuit for Electric Heater Model)
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 conclensed water.
If the air conditioner is used in hot and a high
humidity zone, exchange the @ HOLE RUBBER
for the Q) DRAIN PIPE.(See figure 20, figure 21.)
