B.Thru-The-Wall Installation

NOTE: Consult local building codes prior to installation, or a qualified carpenter.

1 Select Wall Location

The air conditioner has a slide-out chassis, so that it can be installed through an outside wall as specified below:

Max. Wall thickness: 12 " or 10 "

IMPORTANT: Side louvers must never be blocked.

NOTE: All parts needed for Thru-The-Wall Installation are provided, except a wood frame, shims, and 10 wood screws(#10-1 lõng minimum).

Select a wall surface that:

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, and is not blocked to the area to be cooled.
5. allows unblocked airflow from rear sides and end(outside) of installed air conditioner.

2 Prepare Wall

1. 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).
2. Cut or knock out a hole on each side of center stud.
3. Measure between inside edges of every other stud as shown in Fig.1.

3-3/8" MIN (8.6 cm) 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.

Inside Frame Height: 18-7/8"(47.9cm) or 18" (45.7cm) Inside Frame Width: 26-3/4"(67.9cm) or 23-7/8"(60.6cm)

Inside Frame Height Inside Frame Width Up to 8-1/2" Y Fig.2

1. 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 opening to the studs with wood spacers, as shown.
2. Nail frame to spacers to spacers with front flush with drywall.

NAIL SPACERS TO STUDS LEVEL Fig.3

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

Caulkas Required Aluminum Flashing Over Bottom Of Frame Over 8-1/2"

3 Prepare and Install Cabinet

1. Slide chassis from cabinet. Refer back to Step one of Window Mounting.
2. Place cabinet into opening with bottom rail resting firmly on bottom board of wooden frame.
3. Position cabinet to achieve proper slope for water removal.(See Fig.5 below.)
4. Secure bottom rail to wood frame with two large wood screws 1 (2.5cm) long using the two holes in the bottom of the channel resting on frame. (See Fig.6).

NOTE: Check that air conditioner is tilted back about 1^1 / 4^6 to 1 / 8^ (tilted about 3 to 4 downward to the outside). After proper installation, condensate should not drain from the overflow drain hole during normal use, correct the slope otherwise (Fig.14).

1. Install chassis into cabinet by following all steps in Step 8 of Window Mounting.

OPTIONAL: Caulking and installation of trim on interior wall may be done. You can buy wood from your local number or hardware supply. On the outside, caulk openings around top and sides of cabinet, and all sides of wood sleeve to the opening.

NOTE: See Step 5, Item 3 of Window Mounting Instructions for bottom rail seal location.

C.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 do this is to build an in-between frame of 2x4 s' as shown in the Step 2 Prepare Wall illustrations-but make it double framed on either side, and install between masonry wall opening and cabinet. Frame must be securely anchored to masonry wall opening). 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 additional holes can be drilled to fasten cabinet at various positions. Be sure that side louver clearance is in accordance with Step 1 above.
4. Install exterior cabinet support brackets as shown in Step 2 of Thru-the-wall installation. Caulk or flash if needed, to provide a wether-tight seal around top and sides of cabinet.
5. To complete installation, apply wood trim molding around room side projection of cabinet.

High Pitched Chatter High efficiency compressors may have a high pitched chatter during the cooling cycle. Vibration Unit may vibrate and make noise because of poor wall or window construction or incorrect installation. Sound of Rushing Air At the front of the unit, you may hear the sound of rushing air being moved by the fan Gurgle/Hiss "Gurgling or hissing"noise may be heard due to refrigerant passing through evaporator during normal operation. Pinging or Switching Droplets of water hitting condenser during normal operation may cause "pinging or switching"sounds.

Air Directional Louvers

Air Directional Louvers

Air Direction(4- way)

The 4-way air directional louvers allow you to direct the air flow Up or Down(on some models) and Left or Right throughout the room as needed. To adjust the air directional louvers side-to -side, use the center handles as you move it side-to-side.

ADDITIONAL THINGS YOU SHOULD KNOW

Now that you have mastered the operating procedure, here are more features in your control that you should become familiar with.

- 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.

- The control is capable of displaying temperature in degrees Fahrenheit or degrees Celsius. To convert from one to the other, press and hold the Left and Right Temp/Timer buttons at the same time, for 3 seconds.
