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.

Installation
Clearance
Proper clearance enhances the cooling efficiency of the unit and prevents heat
radiation of the condenser.
1. If a storm window presents interference, fasten a 2" wide wood strip to the inner
window sill across the full width of the sill.The wood strip should be thick
enough to raise the height of the window sill so that the unit can be installed
without interference by the storm window frame.
2. See Figure. B.The top of the wood strip should be approximately 3/4" higher
than the storm window frame (Storm Window Frame) or wood strip (Outdoors)
to help condensation to drain properly to the outside.
3. Install a second wood strip (approximately 6" long by 11/2" wide and same
thickness as first strip) in the center of the sill flush against the back off the
inner sill.This will raise the Lbracket as shown Figure. B.
4. If the distance between Storm Window Frame and Wood Strip Mounted on Top
of Inner Sill is more than 1", two of wood strips are not necessary.

Low Fan - Low speed fan operation without cooling.
High Cool - Cooling with high speed fan operation.
Low Cool - Cooling with low speed fan operation.
This automatically controls the temperature of the indoor air.
Turn the knob so that arrow points to the larger marks for greater
cooling. Point the arrow to the smaller marks for more moderate
cooling.
(i.e. the higher the number, the greater the cooling)

Air Direction
Adjusting the air direction using the
horizontal air deflector control.
Using the control tabs, the air flow can
be directed to the left, right, straight
ahead, or any combination of these
directions.
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, below.)
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 slipping 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.
