Installation

This air conditioner is designed with a button-down chassis so it can be easily installed in a window.

3.1 SELECT THE BEST LOCATION

To prevent vibration and noise, make sure the unit is installed securely and firmly.
Install the unit where the sun does not shine directly on the unit.
The outside of the cabinet must extend outward for at least 10" and there should be no obstacles, such as a fence or wall, within 20" from the back of the cabinet because it will prevent heat radiation of the condenser. Restriction of outside air will greatly reduce the cooling efficiency of the air conditioner.

CAUTION: All side louvers of the cabinet must remain exposed on the outside of the structure.

Install the unit slanted slightly so the back is slightly lower than the front (about 1/4"). This will force condensed water to the outside.
Install the unit with the bottom about 30"~60" above the floor level.

Figure 22: Diagram illustrating the recommended installation location for an air conditioner in a window. It shows the unit positioned with the outside extending outwards, away from a fence or wall. Key elements indicated are "INSIDE", "OUTSIDE", "AWNING", "FENCE", "COOLED AIR", and "HEAT RADIATION". Measurements include "ABOUT 1/4"" for the slant and "Over 20"" clearance from obstacles.

3.2 HOW TO INSTALL

3.2.1 WINDOW REQUIREMENTS

NOTE: All supporting parts should be secured to firm wood, masonry, or metal.

This unit is designed for installation in standard double hung windows with actual opening widths of 22" to 36". The upper and lower sash must open sufficiently to allow a clear vertical opening of 13" from the bottom of the sash to the window stool.
If 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. See Figure. 24. Top of 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.
Install a second wood strip (approximately 6" long by 11/2" 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 the L bracket as shown Figure. 24.
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.

Figure 23: Diagram illustrating window sill requirements for installation. It shows the "INNER SILL" and "OUTER SILL" from an indoor perspective. A "WOOD STRIP MOUNTED ON TOP OF INNER SILL" is depicted to raise the sill height, with "INDOORS" and "OUTDOORS" labels.

Figure 24: Detailed diagram showing the use of a "WOOD STRIP FOR L BRACKET" mounted on the inner sill. It illustrates the relationship between the "INNER SILL", "OUTER SILL", "STORM WINDOW FRAME", and the "L BRACKET". Measurements like "1\" MAX." and "3/4" CLEARANCE" are shown.

3.2.2 BEFORE INSTALLATION

Insert the guide panels into the guides of the air conditioner. Fasten the curtains to the unit with screws (TYPE A) as shown Figure. 25.
Cut the adhesive-backed seal strip (TYPE D) to the window width. Remove the backing from the seal strip and attach the seal strip to the underside of the bottom window. (Figure. 26)

3.2.3 NOW START INSTALLATION

LOCATING UNIT IN WINDOW
Open the window and mark center line on the center of the inner sill, as shown in Figure. 27.
ATTACH L BRACKET
a. Install the L brackets behind the inner window sill, with the short side of bracket as shown. Use the 2 screws (TYPE A) provided.
b. The bracket helps to hold unit securely in place. Be sure to place bracket edge flush against back of inner sill. See Figure. 27.

CAUTION: During the following step, hold unit firmly until window sash is lowered to top channel behind side panel frames. Personal injury or property damage may result if unit falls from window.

INSTALL THE AIR CONDITIONER IN THE WINDOW
a. 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 L bracket. See Figure. 28.

Figure 27: Diagram showing the process of marking a "CENTER LINE" on the "INNER SILL" of the window to ensure proper unit alignment.

Installation (Continued)

IMPORTANT: When the air conditioner drops into the L bracket, the air conditioner will be centered in window opening as shown in Figure. 29.

b. While steadying the air conditioner, carefully bring the window sash down behind the upper guide of the air conditioner, as shown in Figure. 30.

Figure 29: Diagram showing the air conditioner unit centered within the window opening, with the "CENTER LINE" indicated.

Figure 30: Diagram illustrating the process of lowering the window sash down behind the "UPPER GUIDE" of the air conditioner unit.

4. SECURE THE GUIDE PANELS

Extend the guide panels (TYPE F) to fill the window opening using 4 screws (TYPE B) to secure them, as shown in Figure. 31.

5. INSTALL THE SASH SEAL AND SASH LOCK

a. Cut the sash seal (TYPE E) to the window width. Stuff the sash seal between the glass and the window to prevent air and insects from getting into the room, as shown in Figure. 31.

b. Fasten the L bracket using a (TYPE A) screw, as shown in Figure. 31.

Figure 31: Diagram showing the "GUIDE PANELS" (TYPE F) extended and secured with "TYPE B" screws, and the "SASH SEAL" (TYPE E) installed between the window sashes.

6. a. Remove the screws that secure the cabinet and base pan in the right side.

b. Fasten the support bracket (TYPE G) using a removed screw. Attach the support bracket (TYPE G) in the inner window sill with a screw (TYPE B), as shown Figure. 32.

Figure 32: Diagram illustrating the attachment of the "SUPPORT BRACKET" (TYPE G) to the "INNER WINDOW SILL" using a screw.

7. Window installation of room air conditioner is now completed.

See ELECTRICAL DATA for attaching power cord to electrical outlet.

3.2.4 How to Secure the 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. (Figure. 33)

Figure 33: Diagram showing how to secure the "DRAIN PIPE" by attaching it to the rear hole of the "BASE PAN" to drain excess water. It shows a "DRAIN CAP" and the pipe in "hang" and "push" positions.
