Installation and Accessory Parts

2

1. This unit is designed for installation in standard double hung windows
with actual opening widths of 21 to 35 . The upper and lower sash
must open sufficiently to allow a clear vertical opening of 12 from the
bottom of the sash to the window stool.

2. If storm window presents interference, fasten a 2 wide wood strip(not
included) (OUTER SILL) 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 (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 3/2 wide and
same thickness as first strip) in the center of the outer sill flush against
the back off the inner sill. This will raise basepan angle .

4. If the distance between STORM WINDOW FRAME and WOOD STRIP
MOUNTED ON TOP OF INNER SILL is more than 1 , two of wood
strip are not necessary.

LOCATING UNIT IN
WINDOW

Open the window and mark center line on the
center of the inner sill.

Install the basepan angle behind the inner window sill, with
the short side of basepan angle as shown. Use the 2 short
screws13/32" provided.
The basepan angle helps to hold unit securely in place.
Be sure to place basepan angle edge flush against back
of inner sill.

Installation and Accessory Parts

INSTALL THE AIR CONDITIONER
IN THE WINDOW

Carefully lift the air conditioner and slide it into the open
window. Make sure the bottom guide of the air conditioner
drops into the notches of the basepan angle.
While steadying the air conditioner ,carefully bring the
window sash down behind the upper guide of the air
conditioner.

INSTALL THE SEAL GASKET
AND SASH LOCK

Extend the side curtains to fill the
window opening using 4 wood screws
31/32" to secure them.
Cut the seal gasket to the window
width. Stuff the sash seal between the
glass and the window to prevent air
and insects from getting into the room.
Fasten the basepan angle, using a
short screw13/32".

Abnormity Diagnose

1. Sensor diagnose: 2 seconds after the sensors open circuit or short
circuit, the unit will turn off automatically and the LED will show E0 until
the sensors resume.

2. Keystroke circuit error diagnose: When power on for the first time, the
PCB will check the keystroke circuit, if the sampling value is different with
the theory value, the LED will show E1, which means failed keystroke
circuit. The keyboard is locked and so invalid, but the remote control is
working normally.

Maintenance Service and Trouble Shooting

Always unplug your air conditioner before cleaning.

The air filter behind the inlet grille should be checked and cleaned at least once
every 2 weeks (or as necessary) to maintain optimal performance of the air
conditioner.

How to remove the air filter

1. The grille may be opened from the top for easy maintenance after installation.

2. Open the inlet grille by pulling off the exposed door on the top of the unit(based
on the installation).

3. Pull the tab slightly to release the filter. Pull the filter in the same direction as
the opening.

4. Clean the filter with warm, soapy water. The water should be below 40oC(104oF).

5. Rinse off and gently shake off excess water from the filter. Let it dry before
replacing it.

DO NOT use your air conditioner without the air filter in place.
To clean the front panels or the cabinet DO NOT use harsh

chemicals, abrasives, ammonia, chlorine, bleach, concentrated
detergents, solvents or metal scouring pads.

Always use a soft cloth dampened with water or mild soap
and water solution to wipe the front of the cabinet.
