IMPORTANT SAFETY INFORMATION | READ ALL INSTRUCTIONS BEFORE USING THE APPLIANCE
HOW TO POWER
• Do not, under any circumstances, cut or remove the third (ground) prong from the power cord.
For personal safety, this appliance must be properly grounded.
• DO NOT use an adapter plug with this appliance.
• The power cord of this appliance is equipped with a 3-prong (grounding) plug which mates
with a standard 3-prong (grounding) wall outlet to minimize the possibility of electric shock
hazard from this appliance.
• Power cord includes a current interrupter device. A test and reset button is provided on the plug
case. The device should be tested on a periodic basis by rst pressing the TEST button and then the
RESET button while plugged into the outlet. If the TEST button does not trip or if the RESET button will
not stay engaged, discontinue use of the air conditioner and contact a qualied service technician.
• Have the wall outlet and circuit checked by a qualied electrician to make sure the outlet
is properly grounded.
• Where a 2-prong wall outlet is encountered, it is your personal responsibility and obligation to
have it replaced with a properly grounded 3-prong wall outlet.
• The air conditioner should always be plugged into its own individual electrical outlet which has
a voltage rating that matches the rating plate.
• This provides the best performance and prevents overloading house wiring circuits which
could cause a re hazard from overheated wires.
• See the Installation Instructions, Electrical Requirements section for specic electrical
connection requirements.
WARNING
USE OF EXTENSION CORDS
RISK OF FIRE. Could cause serious injury or death.

INSTALLATION INSTRUCTIONS
1WINDOW REQUIREMENTS
• These instructions are for a standard double-hung
window. You will need to modify them for other types
of windows.
• The air conditioner can be installed without the side
curtain panels if needed to t in a narrow window.
See the window opening dimensions.
• All supporting parts must be secured to rm wood,
masonry or metal.
• The electrical outlet must be within reach of the
power cord.
• Follow the dimensions in the table and illustration
for your model.
2STORM WINDOW REQUIREMENTS
• A storm window frame will not allow the air
conditioner to tilt toward the outside and
will keep it from draining properly. To adjust
for this, attach a piece of wood to the sill.
WOOD PIECES
– Width: 2″
– Length: Long enough to t inside the window frame.
– Thickness: To determine the thickness, place a
piece of wood on the sill to make it 1/2″ higher than
the top of the storm window frame or the vinyl frame.
• Attach securely with nails or screws provided
by the installer.
3PREPARE THE AIR CONDITIONER
A. Screw the top mounting rail onto
the top of the AC with 3 Type A screws.
B. Slide the curtain panels into the side panel rails.
C. Slide left and right side curtain frames into top
and bottom rails. Make sure that side curtains
snap into side of the frames.

TROUBLESHOOTING TIPS
ISSUE POSSIBLE CAUSE WHAT TO DO
Air conditioner
does not start
The unit is unplugged Make sure the air conditioner plug is pushed completely into the outlet.
The fuse is blown/circuit
breaker is tripped
Check the house fuse/circuit breaker box and replace the fuse
or reset the breaker.
Power failure
The unit will automatically restart in the setting last used after the
power is restored.
There is a protective time delay (approximately 3 minutes) to prevent
tripping of the compressor overload. For this reason, the unit may
not start normal cooling for 3 minutes after it is turned back on.
The current interrupter
device is tripped
Press RESET button located on the power cord plug.
If the RESET button will not stay engaged, discontinue use of
the air conditioner and contact a qualied service technician.
Air conditioner
does not cool
as it should
Indoor airow is restricted Make sure there are not curtains, blinds or furniture blocking the
front of the air conditioner.
The temp control may
not be set properly Turn the temperature control to a higher number.
The air lter is dirty Clean the lter at least every 30 days.
See Care and Cleaning section.
The room may have been hot When the air conditioner is rst turned on, you need to allow time
for the room to cool down.
Cold air is escaping Check for open furnace registers and cold air returns.
Cooling coils have iced up See “Air conditioner freezing up” below.
Air conditioner
freezing up
Ice blocks the air ow and
stops the air conditioner
from cooling the room
On models with control knobs, set the mode control at High Fan
or High Cool with the Temp at 1 or 2. May have lost refrigerant.
Water drips
outside Hot, humid weather This is normal.
Water drips
inside
The air conditioner is not
tilted to the outside
For proper disposal, make sure the air conditioner slants slightly
from the case front to the rear.
Water collects
in base pan
Moisture removed from
air and drain into base pan
This is normal for a short period in areas with little humidity;
normal for a longer period in very humid areas.
Review the chart for Troubleshooting Tips. If issue persists, please call for further assistance.

TROUBLESHOOTING TIPS
NORMAL OPERATING SOUNDS
• You may hear a pinging noise caused by water being picked up and thrown against the
condenser on rainy days or when the humidity is high. This is normal, unit is equipped
with a slinger blade which scoops up the water from the drain pan and throws it onto
the coils for better eciency.
• You may hear the thermostat click when the compressor cycles on and o.
• Water will collect in the base pan during high humidity or on rainy days. The water may
overow and drip from the outdoor side of the unit. The drain plug may be removed for
quicker drainage.
• The fan may run even when the compressor does not.
• Drain plug may be removed for gravity drain but may reduce eciency.
• DO NOT drill any holes.
