3. INSTALLATION
This air conditioner is designed with a button-
down chassis so that it can be installed simply in
a window.
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 10" 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 1/4"). This will force
condensed water to the outside.
5. Install the unit with 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 under mentioned items are especially
important checking points when the installation
is finished.
1. Grounding wire (Green of Green Yellow) is pro-
vided in the power cord. The green wire must be
grounded.
2. Connect to a single-outlet 15AMP circuit.
3. To avoid vibration or noise, make sure the air
conditioner is installed securely.
4. Avoid placing furniture or dreperies in front of the
air inlet and outlet.
3.3 HOW TO DRAIN
(When using drain pipe)
The air conditioner must be installed level or
titled slightly to the outside for proper water
drainage. On exceptionally hot and humid days
the air conditioner may drain condensation
water through overflow. If the air conditioner is
used in hot and a high humidity zone, exchange
the
HOLE RUBBER for the
DRAIN PIPE.
