Location Requirements
IMPORTANT: Observe all governing codes and
ordinances.
Check the location where air conditioner will be
installed. Proper installation is your responsibility.
Make sure you have everything necessary for
correct installation.
The location should provide:
Grounded electrical outlet within 6 ft of
where the power cord exits the air
conditioner.
NOTE: Do not use an extension cord.
Free movement of air in room to be cooled.
A large enough opening for the air
conditioner.
Adequate wall support for weight of air
conditioner. Air conditioner weights up to 70
lbs.
NOTE: Cabinet louvers & rear of the air
conditioner must not be obstructed. Air must be
able to pass freely through the cabinet louvers.
The rear of air conditioner must be outdoors. Not
inside a building or garage.
Window 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
accordion panel if needed
to fit in a narrow window.
See Window Opening

All supporting parts must be secured to firm
wood, masonry or metal.

TABLE -2
Storm Window Requirements:
A storm window frame will not allow the air
conditioner to tilt properly which in turn will keep
it from draining properly. To adjust for this,
attach a board or piece of wood to the sill. The
board or wood piece should have a depth of at
least 1 1/2”. Make sure the board or piece of
wood is approximately 1/2” higher than the
storm window frame. This will allow the air
conditioner to tilt enough for proper drainage.

TABLE - 3
Recommended Grounding Method
This air conditioner must be grounded. This air
conditioner is equipped with a power supply cord
having a grounded 3 prong plug. To minimize
possible shock hazard, the cord must be
plugged into a mating, grounded 3 prong outlet,
grounded in accordance with all local and
national codes. If a mating outlet is not available,
it is the customer’s responsibility to have a
properly grounded 3 prong outlet installed by a
qualified electrical installer.
It is the customer’s responsibility:
To contact a qualified electrical installer.
To assure that the electrical installation
is adequate and in conformance with
National Electrical Code, ANSI/NFPA
70- latest edition, and all local codes
and ordinances.
Power Supply Cord
NOTE: Your unit’s device may differ from the
ones shown.
This room air conditioner is equipped with a
power supply cord required by UL. This power
supply cord contains state-of-the-art electronics
that sense leakage current. If he cord is crushed,
the electronics detect leakage current and power
will be disconnected in a fraction of a second.
To Test your power supply cord:
1. Plug power supply cord into a grounded 3
prong outlet.
2. Press RESET
3. Press TEST (listen for click, Reset button
will trip and pop out).
4. Press and release RESET (listen for click;
Reset button will latch and remain in). The
power supply cord is ready for operation.
NOTES:
The reset button must be pushed in for
proper operation.
The power supply cord must be replaced if it
fails to trip when the test button is pressed
or fails to reset.
Do not use the power supply cord as an
off/on switch. The power supply cord is
designed as a protective device.
A damaged power supply cord must be
replaced with a new power supply cord
obtained from the product manufacturer and
must not be repaired.
The power supply cord contains no user
serviceable parts. Opening the tamper-
resistant case voids all warranty and
performance claims.

INSTALLATION INSTRUCTIONS
Remove packaging materials
Remove and dispose of/recycle packaging
materials. Remove tape and glue residue
from surfaces before turning on the air
conditioner. Rub a small amount of liquid
dish soap over the adhesive with your
fingers. Wipe with warm water and dry.
Do not use sharp instruments, rubbing
alcohol, flammable fluids, or abrasive
cleaners to remove tape or glue. These
products can damage the surface of your air
conditioner.
Handle air conditioner gently.
Prepare Your Unit
Install the Top Mounting Rail
Locate provided bag of screws.
Place top mounting rail on top of air
conditioner, lining up the 4 holes in rail with
the 4 holes on top of air conditioner.
Using 4 screws, attach top mounting rail to
air conditioner.
NOTE: Your unit may have top rail preinstalled,
skip this step if it is installed.
NOTE: Your units
may have the seal
strip already attached
to the top mounting
rail. If applicable, skip
this step.
Attach the rail seal
strip
Remove the backing
from the top
mounting rail seal
strip and attach the seal strip to the bottom of
the top mounting rail, along the front edge.

Page 6
Install the Accordion Panel
Hold the accordion panel in one hand and
gently pull back to free the open end.
Slide the free end and (I section) of the
accordion panel into the cabinet as shown in
Fig 2. Slide the panel down. Be sure to
leave enough space to slip the top and
bottom of the frame into the rails on the
cabinet.
NOTE:
There is a right and a left accordion panel. Be
sure to use the proper panel for each side.
Once the panel has been installed on the
side of the cabinet, make sure it sits
securely inside the frame channel by making
slight adjustments. Slide the top and bottom
ends of the frame into the top and bottom
rails of the cabinet. See Fig.3.
Slide the panel all the way in and repeat on
the other side.
Install Your Air Conditioner in the
Window
Handle air conditioner gently.
Be sure your air conditioner does not fall out
of the opening during installation or removal.
The place where the power cord exits the air
conditioner should be no more than 6 ft (182
cm) from a grounded 3 prong outlet.
Do not block the louvers on the front panel.
Do not block the louvers on the outside of
the air conditioner.

Install Your Unit
Center the air conditioner in window. Check
that lower rail of air conditioner is behind
and against back side of window sill.
Maintain a firm hold on the air conditioner
cabinet. Lower window sash to hold cabinet
in place.
Measure the distance between the right-
hand side of the cabinet and the inside of
the window channel.
Repeat for the left side. Adjust the cabinet
until the distance on each side is the same.
Extend the left and right accordion panels to
the vertical window sashes and use the
screws to attach.
Install the frame locking brackets between
the bottom of the accordion panel and the
window sill. Attach with 2 screws.
To prevent the window sill from splitting,
drive the pilot holes before driving screws.
Check that air conditioner cabinet is tilted to
the outside so that water will run to the
outside.
Install the Support Bracket and Seal the
Window
CAUTION:
To prevent broken glass or damage to windows,
on vinyl or other similarly constructed windows,
attach the window locking bracket to the window
side jamb with one screw.
Attach the right angel sash lock with screw
as shown below.
Cut the foam top window gasket to the
window width.
Stuff the foam between the glass and the
window to prevent air and insects from
getting into the room.
If the gasket supplied does not fit the window,
obtain appropriate material locally to provide a
proper installation seal.

The Cool circuit has an automatic 3 minute time delayed start if the unit is turned off and on quickly. This prevents
overheating of the compressor and possible circuit breaker tripping. The fan will continue to run during this time.
Select ℉ or ℃
The unit is shipped in degree F as the default indication.
The control is capable of displaying temperature in degrees Fahrenheit or degrees Celsius. To convert from one to the
other, press and hold the UP and DOWN temperature (Timer) buttons on control panel simultaneously for 3 seconds.

Air Directional Louvers
Air Direction
Normal Sounds
When your air conditioner is operating normally, you may hear sounds such as:
Droplets of water hitting the condenser, causing a pinging or clicking sound. The water droplets help to cool
the condenser.
Air movement, for improved operation.
Clicks from the thermostat cycling.
Vibrations or noise due to poor wall or window construction.
A high-pitched hum or pulsating noise caused by the modern high-efficiency compressor cycling on and off.
The louvers will allow you to direct the air flow Up or
Down (on some models) and Left or Right
throughout the room as needed. Pivot horizontal
louvers until the desired Up/Down direction is
obtained.
Move the Levers from side to side until the desired
Left/Right direction is obtained.
