Operating on AUTO mode:

• When you set the air conditioner in AUTO mode, it will automatically select cooling, heating (selected models only) or fan only operation depending on what temperature you have selected and the room temperature.
• The air conditioner will control room temperature automatically to hit the temperature set point you choose.
• In this mode, the fan speed cannot be adjusted, it starts automatically at a speed according to the room temperature.

Operating on FAN mode:

• Use this function only when cooling is not desired, such as for room air circulation or to exhaust stale air (on some models). (Remember to open the vent during this function, but keep it closed during cooling for maximum cooling efficiency.) You can choose any fan speed you prefer.
• During this function, the display will show the actual room temperature, not the set temperature as in the cooling mode.
• In Fan only mode, the temperature can not be adjusted.

Operating on DRY mode:

• In this mode, the air conditioner will operate in the form of a dehumidifier. Since the conditioned space is a closed or sealed area, some degree of cooling will continue.

(FAN SPEED) Button

Used to select the Fan Speed in four steps - Auto, Low, Med or High. Each time the button is pressed, the fan speed mode is shifted. On Dry mode,the fan speed is controlled at low automatically.

(ENERGY SAVER) Button

This function is available on COOL, DRY, AUTO (only AUTO-COOL and AUTO-FAN) modes. The fan will continue to run for 3 minutes after the compressor shuts off. The fan then cycles on for 2 minutes at 10 minute intervals until the room temperature is above the set temperature, at which time the compressor turns back on and Cooling Starts.

(SLEEP) Button

In this mode the selected temperature will increase by 2°F/1°C 30 minutes after the mode is selected. The temperature will then increase by another 2°F/1°C after an additional 30 minutes. This new temperature will be maintained for 6 hours before it returns to the originally selected temperature. This ends the Sleep mode and the unit will continue to operate as originally programmed. The Sleep mode program can be cancelled at any time during operation by again pressing the Sleep button.

3. Exchange air from the room and draws fresh air into the room - Vent and Exhaust Open (See Fig. C).

Air Directional Louvers

The louvers will allow you to direct the air flow up or down and lefft 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.

Installation Instructions

Your air conditioner is designed to install in standard double hung windows with opening widths of 23 to 36 inches (584mm to 914mm) (See Fig. D).

NOTE: Save Carton and these Installation Instructions for future reference. The carton is the best way to store unit during winter, or when not in use.

1. PREPARE THE WINDOW
   Lower sash must open sufficiently to allow a clear vertical opening (H) of following size (see Table 1). Side louvers and the rear of the AC must have clear air space to allow enough airflow through the condenser, for heat removal. The rear of the unit must be outdoors, not inside a building or garage.
   
   NOTE: The top rail hardware and the following Fig. E, Fig. F and Fig. G are not applicable to the units over 10,000 Btu/h.
2. PREPARE AIR CONDITIONER
   Before installing unit, the top rail must be assembled on the unit for models with a capacity of less than 10,000Btu/h.
   
   • A: Remove the air conditioner from the carton and place on a flat surface.
   • B: Remove top rail from the bottom of the packaging material as shown in Fig. E.
   • C: Align the hole in the top rail with those in the top of the unit as shown in Fig. F.
   • D: Secure the top rail to the unit with the 3/8” screws as shown in Fig. G.

NOTE: For safety reasons, all four (4) screws MUST be securely fastened.

How To Install

1. Place unit on floor, a bench or a table. There is a left and right side filler panel; be sure to use the proper panel for each side. When installed, the flange for securing the panel in place to the window sill will be facing into the room.
   • A. Hold the side panel in one hand and gently pull back the center to free the open end. See Fig. 1.
   • B. Slide the free and “I” section of the panel directly into the cabinet as shown in Fig. 2A. 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.
     
   • C. 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. Fig. 3.
     
   • D. Slide the panel all the way in and repeat on the other side.
     NOTE: If storm window blocks AC, see Fig. 10.
2. While keeping a firm grip on the air conditioner, carefully place the unit into the window opening so the bottom of the air conditioner frame is against the window sill (Fig. 4). Carefully close the window behind the top rail of the unit.
   
   NOTE: Check that air conditioner is tilted back about H (Fig. 5) (tilted about 3° to 4° downward to the outside). After propor installation, condensate should not drain from the overflow drain hole during normal use, correct the slope otherside.
3. Extend the side panels out against the window frame (Fig. 5).
   
4. Place the frame lock between the frame extensions and the window sill as shown (Fig. 6). Drive 3/4” (19mm) or 1/2” (12.7mm) locking screws through the frame lock and into the sill.
   
   
   NOTE: To prevent window sill from splitting, drill 1/8” (3mm) pilot holes before driving screws.
5. Drive 3/4” (19mm) or 1/2” (12.7mm) locking screws through frame holes into window sash (Fig. 7).
   
6. To secure lower sash in place, attach right angle sash lock with 3/4” (19mm) or 1/2” (12.7mm) screw as shown (Fig. 8).
   
7. Cut window sash seal foam and insert it in the space between the upper and lower sashes (Fig. 9).
   

If AC is Blocked by Storm Window

Add wood as shown in Fig. 10, or remove storm window before air conditioner is installed. If storm window frame must remain, be sure the drain holes or slots are not caulked or painted shut. Accumulated rain water or condensation must be allowed to drain out.
