Before Operation
1. Plug in the power cord properly.
2. Use a dedicated circuit. Overloading the line could create a fire hazard.
3. Do not use an extension cord. See page 11 for more details.
4. Do not start/stop operation by plugging/unplugging the power cord.
5. If the power cord is damaged and requires replacement, have an Authorized
Servicer install an exact replacement part.
1. Being exposed to direct airflow for an extended period of time could be
hazardous to your health. Do not expose occupants, pets, or plants to direct
airflow for extended periods of time.
2. Due to the possibility of oxygen deficiency, ventilate the room when used
together with stoves or other heating devices.
3. Do not use this air conditioner for non-specified special purposes (e.g.
preserving precision devices, food, pets, plants, and art objects). Such usage
could damage the items.
4.The air conditioner is a consumer comfort appliance, not a precision climate
control system.
1. Do not touch the metal parts of the unit when removing the filter. Injuries can
occur when handling sharp metal edges.
2. Do not use water to clean inside the air conditioner. Exposure to water can
destroy the insulation, leading to possible electric shock.
3. When cleaning the unit, first make sure that the power and breaker are turned
off. The fan rotates at a very high speed during operation.There is a
possibility of injury if the unit’s power is accidentally triggered on while
cleaning inner parts of the unit.
For repair and maintenance, contact an Authorized Service Center. See the
warranty page for details or call 1-877-755-7932. Have your model number and
serial number available.They should be written on page 2 of this manual.

ELECTRICAL SAFETY
IMPORTANT GROUNDING INSTRUCTIONS
Air conditioner has a three-prong grounding plug on its power supply cord, which must be plugged into
properly grounded three-prong wall receptacle for your protection against possible shock hazard.

WARNING: This appliance must be properly grounded.
The power cord of this appliance is equipped with a three-prong grounding plug.
To minimize the risk of electric shock, use the plug with a standard three-slot
grounding wall power outlet. If the power outlet does not include a grounding slot,
have a qualified electrician replace the outlet before you use the room air
conditioner.
WARNING: Changing the outlet without making the appropriate wiring
changes will create an unsafe condition that could result in fire or
electric shock. Refer all such work to a licensed and qualified
electrician.
WARNING: Do not cut or remove the grounding prong from the power
plug.
WARNING: 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.
WARNING: If you have any doubt whether the air conditioner is
properly grounded, have the wall receptacle and circuit checked by a
qualified electrician.
Preferred method
Ensure proper ground
exists before use

Electrical Safety

We strongly discourage the use of an adapter due to potential safety hazards.
For temporary connections, use only a UL-listed adapter, available from most
local hardware stores. Ensure that the large slot in the adapter is aligned with
the large slot in the receptacle for a proper polarity connection.
To disconnect the power cord from the adapter, use one hand on each to avoid
damaging the ground terminal. Avoid frequently unplugging the power cord as
this can lead to eventual ground terminal damage.
WARNING: Never use the appliance with a broken adapter.

How to Install the Unit
To prevent vibration and noise, make sure the unit
is installed securely and firmly
Install the unit where the sunlight does not shine
directly on the unit.
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.
Install the unit a little slanted so the back is slightly lower than the front (about 1/2").
This will force condensed water to flow to the outside.
Install the unit with the bottom about 30"~60" above the floor level.

Drain Pipe
In humid weather, excess water may
cause the Base Pan to overflow. To
drain the water, remove the Drain Cap
and secure the Drain Pipe to the rear
hole of the Base Pan.
Press the drain pipe into the hole by
pushing down and away from the fins
to avoid injury.
This air conditioner is equipped with a
slinger fan. (See drawing, right.)
The fan has an outer ring that runs in
the water that collects in the base pan
if it gets deep. That condensate is then
picked up by the fan and expelled
through the condenser, making the air
conditioner more efficient.
CAUTION: Be careful when inserting the drain pipe. Push away from
the sharp fin area to avoid injuring yourself.
Removal From Window
Turn the air conditioner off, disconnect the power cord, remove the L bracket, the
screws and Support Bracket installed through the top and bottom of the guide
panels, and save for reinstallation later. Close the guide panels. Keeping a firm grip
on the air conditioner, raise the sash, and carefully tilt the air conditioner backward,
draining any condensate. Lift the air conditioner from the window and remove the
sash seal from between the windows.
Be sure to drain ALL condensate from the air conditioner. If you don't, it could run
out while you carry the unit, making a mess and creating a slipping hazard. This
simple step will save you much cleaning and make a safer work environment.
