BeforetoOperation
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.

Use of extension cords
Because of potential safety hazards, we
strongly discourage the use of an extension

extension cord, use a CSA certified/UL-listed
3-wire (grounding) extension cord, rated 15A,
125V.
All wiring should be made in accordance with
local electrical codes and regulations.
Aluminum house wiring may pose special
problems. Consult a qualified electrician.
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.
230, 208, and 2301208 VOLT UNITS
These units are equipped with a three-prong
grounding plug on the power supply cord, which
must be plugged into a matching properly grounded
three-prong wall receptacle for your protection
against possible shock hazard. If such an outlet is
not present, one must be installed by a qualified
electrician in accordance with the National Electrical
Code and local codes and ordinances.
DO NOT USE AN EXTENSION CORD on 230,
208, and 230/208 Volt units.
Owner's Manual 9

ElectricalSafety
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
electrical shock. Refer all such work to alicensed and qualified
electrician.
Preferred method
Ensure proper ground
exists before use
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.

ElectricalSafety
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.

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 L bracket 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.

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.
(_) Hang i (_) Push
DrainPipe--_-_ DrainCap
_k AUTION: 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.
