How to Install the Unit
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 30.5 cm(12") and there
should be no obstacles, such as a fence or wall, within 50.8 cm(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 12.7 mm(1/2")).
This will force condensed water to flow to the outside.
5. Install the unit with the bottom about 76.2~152.4 cm(30"~60") above the floor level.

Electrical Safety
IMPORTANT
(PLEASE READ CAREFULLY)
FOR THE USER'S PERSONAL SAFETY, THIS
APPLIANCE MUST BE PROPERLY GROUNDED
The power cord of this appliance is equipped with a
three-prong (grounding) plug. Use this with a
standard three-slot (grounding) wall power outlet
(Fig. 15) to minimize the hazard of electric shock.
The customer should have the wall receptacle and
circuit checked by a qualified electrician to make
sure the receptacle is properly grounded.
DO NOT CUT OR REMOVE THE THIRD
(GROUND) PRONG FROM THE POWER
PLUG.
A. SITUATIONS WHERE THE APPLIANCE
WILL BE DISCONNECTED ONLY
OCCASIONALLY:
Because of potential safety hazards, we strongly
discourage the use of an adapter plug. However, if
you wish to use an adapter, a TEMPORARY
CONNECTION may be made. Use UL-listed
adapter, available from most local hardware stores
(Fig. 16). The large slot in the adapter must be
aligned with the large slot in the receptacle to
assure a proper polarity connection.
CAUTION: Attaching the adapter ground terminal to
the wall receptacle cover screw does not ground the
appliance unless the cover screw is metal, and not
insulated, and the wall receptacle is grounded
through the house wiring.
The customer should have the circuit checked by a
qualified electrician to make sure the
receptacle is properly grounded.
Disconnect the power cord from the adapter, using
one hand on each. Otherwise, the adapter ground
terminal might break. DO NOT USE the appliance
with a broken adapter plug.
B. SITUATIONS WHERE THE APPLIANCE
WILL BE DISCONNECTED OFTEN.
Do not use an adapter plug in these situations.
Unplugging the power cord frequently can lead to
an eventual breakage of the ground terminal. The
wall power outlet should be replaced by a three-slot
(grounding) outlet instead.
USE OF EXTENSION CORDS
Because of potential safety hazards, we strongly
discourage the use of an extension cord. However,
if you wish to use an extension cord, use a CSA
certified/UL-listed 3-wire (grounding) extension
cord, rated 15A, 125V.
