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 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 WHEN THE APPLIANCE WILL BE

DISCONNECTED 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.
The large slot in the adapter must be aligned with the
large slot in the receptacle to assure a proper polarity
connection.

:

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 WHEN 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
youwishtouseanextensioncord,useaCSA
certified/UL-listed 3-wire (grounding) extension cord,
rated at 15A, 125V.

Airflow can be adjusted by changing the direction of the air conditioner's louvers. This can also increase the
cooling efficiency of the air conditioner.

Adjusting horizontal air flow Adjusting vertical air flow

• Adjusting Horizontal Air Flow Direction

Adjusting the vertical louvers left and right will
change horizontal airflow.

• Adjusting Vertical Air Flow Direction

Adjusting the horizontal vane up and down will
change vertical airflow. The vane can be adjusted
by nudging the vane backward or forward.

Adjusting the Air Flow Direction

For maximum cooling efficiency, CLOSE the vent. This will allow internal air circulation.

How to Attach Drain Pan (Optional)

The air conditioner employs a proper drain method whereby the condensed water (moisture removed from the
air) is drained to the outside.

In very humid weather, (and for reverse cycle models in the reverse mode) excessive condensate water removed
from the air may cause some water to collect. To remove this excess water you can install the drain pan as
detailed below.
