Product Usage Instructions

Check Window Opening Size:
The air conditioner is designed for a wooden sill double-hung window with specific dimensions. Open the sash to a minimum of 19 inches and ensure there is at least 11.8 inches clearance around the unit.

Check Window Condition:
Ensure all wood parts of the window are in good condition and can securely hold the screws provided. Make any necessary repairs before installing the unit.

Check Storm Windows:
If the storm window frame does not allow the required clearance, adjust by adding a piece of wood or removing the storm window during installation.

Check for Airflow Obstructions:
Inspect the area outside the window for obstructions like shrubs, trees, or awnings. Inside, ensure there are no obstacles such as furniture, drapes, or blinds that could block airflow.

FAQ:

• Q: Can I install the air conditioner alone?
  A: No, due to the weight and size of the unit, it is recommended to have two or more people help with installation to prevent injury or damage.

• Q: What should I do if my window dimensions don’t match the specifications?
  A: If your window does not meet the specified dimensions, consider making adjustments to accommodate the unit or consult a professional for guidance.

Preliminary instructions:
Do the following before starting to install unit. See illustrations below .

Check dimensions of your unit to determine model type:

1. Check window opening size: the mounting parts furnished with this air conditioner are made to install in a wooden sill double-hung window. The standard parts are for window dimensions listed above. Open sash to a minimum of 19″ (483mm). (FIG.1)
   There should be at least 11.8 inches (300mm) clearance around the unit. The appliance with electric heater shall have at least 1 meter space to the combustible materials.

2. Check condition of window: all wood parts of window must be in good shape and able to firmly hold the needed screws. If not, make repairs before installing unit.

3. Check your storm windows: If your storm window frame does not allow the clearance required, correct by adding a piece of wood as shown (FIG.2), or by removing storm window while room air conditioner is being installed.

4. Check for anything that could block airflow
   Check area outside of window for things such as shrubs, trees, or awnings. Inside, be sure furniture, drapes, or blinds will not stop proper air flow.

5. Check the available electrical service
   Power supply must be the same as that shown on the unit serial nameplate. (See Use & Care Guide for serial plate location.) Power cord is 48″ long. Be sure you have an outlet near. All models have a 3-prong service plug to provide proper service and safe positive grouding. Do not change plug in any way. Do not use an adapter plug. If your present wall outlet does not match your plug, call a qualified electrician to make the needed change.

6. Carefully unpack air conditioner

31. Adjust height of sill angle bracket so that bracket rests securely on edge of sill, and so that cabinet has about 7/8″ to 1 1/4″ downward tilt for proper water drainage (tilted about 2° to 4° downward to the outside, see Fig. 14). Tighten nuts securely. After proper installation, condensate should not drain from the overflow drain hole during normal use, correct the slope otherwise. FIG.15B

48. Fix the other end of the grounding wire on the lower right corner of the unit. Reconnect electronics plug if present. (see FIG.21B) Position vent control lever so that it will thread into its channel in the front panel (see FIG.21C). Hook front panel top tabs into slots on cabinet top, and rotate front panel down so that side tabs snap into place on cabinet. Insert 4 previously removed screws through front panel and into air conditioner.

49. Insert air conditioner filter. Reinstall the front grille by hooking bottom tabs into slots on Front Panel bottom, then rotating grille up to snap into place.

Thru-The-Wall Installation
NOTE: Consult local building codes prior to installation, or a qualified carpenter.

1. Select Wall Location
   This air conditioner slides out from its cabinet, so that it can be installed through an outside wall as explained below. | Heavy duty| Medium
   ---|---|---
   Max wall thickness| 10″| 8″

NOTE:

1. Does not support major structural loads such as the frame construction at ends of windows, and under truss-bearing points, etc.
2. Does not have plumbing or wiring inside.
3. Is near existing electrical outlets, or where another outlet can be installed.
4. Faces to the area to be cooled, and it is not blocked.
5. Allows unblocked airflow from rear sides and end (outside) of installed air conditioner.

2. Prepare Wall
3. Prepare wall in frame construction (including brick and stucco veneer). Working from inside the room, find wall stud nearest the center of area where air conditioner will be installed (by sounding wall, or by magnetically finding nails).
4. Cut out a hole on each side of center stud.
5. Measure between inside edges of every other stud as shown in FIG.1. Carefully measure and cut an opening with the following dimensions depending on your model. See FIG.1 and FIG.2.
   WIDTH “X” = inside model width plus twice the thickness of framing material used.
   HEIGHT “Y” = inside model height plus twice the thickness of framing material used. | Heavy Duty| Medium
   ---|---|---
   Capacity:| 28,000BTU| 15,000~23,200BTU
   Inside Frame Height:| 18-7/8″ (47.9 cm)| 18″ (45.7 cm)
   Inside Frame Width:| 26-3/4″ (67.9 cm)| 23-7/8″ (60.6 cm)

4. Build a wooden frame with the INSIDE dimensions of your model listed above. (Measure twice remember…) Frame depth should be the same as wall thickness. Fill in the space from the opending to the studs with wood spacers, as shown.
5. Nail frame to spacers to spacers with front flush with dry wall.  

NOTE: If wall thickness is 8-1/2” or more, add alumimum flashing over bottom of frame opening to assure no water can enter area between inner and outer wall.

3. Prepare and Install Cabinet

4. Slide air conditioner from cabinet; refer back to Step 1 of Window Mounting.

5. Place cabinet into opening with bottom rail resting firmly on bottom board of wooden frame.

6. Position cabinet to achieve proper downward tilt for water removal. Unit must tilt back about 7/8″ to 1 1/4″ for proper water drainage. (See FIG.5 below.)

7. Secure bottom rail to wood frame with two large wood screws 1″ (2.5 cm) long using the two holes in the bottom of the channel resting on frame. (See FIG.6 following)
   Refer to Step 5 of Window Mounting for assembly of support brackets. Nail a wooden strip to the outside wall for the angle sill bracket to rest upon. See Fig. 7.

8. Screw or nail cabinet to wooden frame using shims as needed to eliminate cabinet distortion. See Fig. 8. Remember to maintain proper tilt as described in Step 3.

9. Install air conditioner into cabinet by following all steps in Step 9 of Window Mounting.
   OPTIONAL: Caulking and installation of trim on interior wall may be done. You can buy wood from your local lumber or hardware supply. On the outside, caulk opendings around top and sides of cabinet, and all sides of wood sleeve to the opening.
   NOTE: See Step 5, Item 4 of Window Mounting Instructions for bottom rail seal location.

Masonry Construction

1. Cut or build a wall opening in the masonry wall similar to the frame construction (refer to Step 2 of Thru-the-Wall Installation for a wall thickness greater than 8-1/2″).
2. Secure cabinet in place using masonry nails, or the right masonry anchor screws. (Another way to secure cabinet is to build a frame in the masonry wall such as the one shown in Fig. 3 of Step 2 Prepare Wall. Securely anchor frame to masonry wall. This way gives very good louver clearance on either side of cabinet.)
3. Install a lintel to support masonry wall above cabinet. Existing holes in cabinet can be used and/or additions holes can be drilled to fasten cabinet at various positions. Be sure that side louver clearance is in accordance with Step 1 Select Wall Location.
4. Install exterior cabinet support brackets as shown in Step 3 of Thru-the-Wall Installation. Caulk or flash if needed, to provide a weather-tight seal around top and sides of cabinet.
5. To complete installation, apply wood trim molding around room side projection of cabinet.
