• Performance may be reduced outside of these operating temperatures.

Before you begin, thoroughly familiarize yourself with the control panel as shown below and all its functions, then follow the symbol for the functions you desire. The unit can be controlled by the unit control panel alone or with the remote control.

Air Conditioner Features

NOTICE The controls featured in this manual are representative of many available models. Your model’s features and appearance may vary slightly

UNIT CONTROL

THERMOSTAT

The thermostat is used to set the desired room temperature when the unit is being operated in the COOL MODE.

To set the desired room temperature, rotate the thermostat switch to the desired setting. After the set temperature is achieved the thermostat will automatically start and stop the compressor in order to maintain the desired set temperature.

Rotate the thermostat selector clockwise for higher cool settings. Higher cool settings will provide lower room temperature. Rotate the thermostat selector counter clockwise for lower cool settings. Lower cool settings will provide higher room temperature.

COOL MODE

The desired cool setting is selected by rotating the knob clockwise to the desired position.

High Cool has maximum cooling effect and airflow.

Low Cool has minimum cooling effect and airflow.

FAN MODE

Rotate the knob counter clockwise to select your choice of fan speeds for air circulation.

NOTICE When selecting a fan speed, the compressor will not run.

Press ON/OFF button to turn unit on or off.

NOTICE The unit will automatically initiate the Energy Saver function under Cool, Dry, Auto (only Auto-Cooling and AutoFan) modes.

TO CHANGE TEMPERATURE SETTING:

Press Power button to turn unit on or off.

NOTICE Press or hold either UP/DOWN button until the desired temperature is seen on the display. This temperature will be automatically maintained anywhere between 62°F (17°C) and 86°F (30°C). If you want to display the actual room temperature, see To Operate on Fan Only section.

TO ADJUST FAN SPEEDS:

Press to select the Fan Speed in four steps-Auto, Low, Med or High. Each time the button is pressed, the fan speed mode is changed. On Dry mode, the fan operates on Low speed automatically.

SLEEP FEATURE:

Press Sleep button to initiate the sleep mode. In this mode the selected temperature will increase by 2°F/1 (or 2)°C 30 minutes after the mode is selected. The temperature will then increase by another 2°F/1 (or 2)°C after an additional 30 minutes. This new temperature will be maintained for 7 hours before it returns to the originally selected temperature. The Sleep mode program can be cancelled at any time during operation by pressing the Sleep button again.

CHECK FILTER FEATURE:

The Check Filter feature is a reminder to clean the air filter for a more efficient operation. The light will illuminate after 250 hours of operation. After cleaning the filter, press the Filter button to reset the Check Filter function turning the light off.

ENERGY SAVER FEATURE:

Press Energy Saver button to initiate this function. This function is available on COOL, DRY, AUTO (only AUTO-COOLING 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 resumes.

COMFORTSENSE FEATURE:

The ComfortSense function enables the remote control to measure the temperature at its current location. When using AUTO, COOL, or HEAT functions, measuring ambient temperature from the remote control (instead of from the indoor unit itself) will enable the air conditioner to optimize the temperature around you and ensure maximum comfort.

This feature can be activated from the remote control ONLY. The remote control will send this signal to the air conditioner every 3 minutes interval until press the ComfortSense button again.If the unit does not receive the ComfortSense signal during any 7 minutes interval, the unit will beep to indicate the ComfortSense mode has ended.

TO SELECT THE OPERATING MODE:

To choose the operating mode, press the Mode button the unit cycles through the modes, Auto, Cool, Dry, and Fan. The adjacent indicator light will remain on once the mode is selected.

The unit will automatically initiate the Energy Saver function under Cool, Dry, Auto (only Auto-Cooling and Auto-Fan) modes.

To operate on Auto mode:

• The fan speed is automatically controlled based on the temperature setting and room temperature and cannot be adjusted.

• The air conditioner will control room temperature automatically according to the temperature you’ve set.

• In this mode, the fan speed cannot be adjusted, as it’s automatically controlled according to the temperature setting and room temperature.

To operate on Fan Only:

• 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 is not adjusted.

To operate on Dry mode:

In this mode, the air conditioner will generally function as a dehumidifier. Since the conditioned space is a closed or sealed area, some degree of cooling will occur.

TIMER: AUTO START/STOP FEATURE:

• When the unit is on or off, first press the Timer button. The TIMER ON indicator light illuminates indicating the Auto Start program has initiated.

• When the time of TIMER ON is displayed, press the Timer button again. The TIMER OFF indicator light illuminates. It indicates the Auto Stop program has initiated.

• Press or hold the UP or DOWN button to change the Auto time by 0.5 hour increments, up to 10 hours, then at 1 hour increments up to 24 hours. The control will count down the time remaining until start.

• The selected time will register in 5 seconds, and the system will automatically revert back to display the previous temperature setting or room temperature when the unit is on. (when the unit is off, there is no display.)

• Turning the unit ON or OFF at any time or adjusting the timer setting to 0.0 will cancel the Auto Start/Stop timed program.

• If setting ON 0.5 and OFF 1 at the same time, the unit will be activated in 0.5 hour, operates for 0.5 hour and then stops.

Displays:

Shows the set temperature in “°C” or “°F” and the Auto-timer settings. While on Fan Only mode, it shows the room temperature.

Error codes:

AS - Room temperature sensor error - Unplug the unit and plug it back in. If error repeats, call for service.

NOTE : In Fan only mode , if the room temperature too low or too high, it will display “LO” or “HI”

ES - Evaporator temperature sensor error - Unplug the unit and plug it back in. If error repeats, call for service.

NOTICE If the unit shuts off unexpectedly due to the power outage, it will restart with the previous function setting automatically when the power resumes.

Additional Information

Now that you understand 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 can display temperature in Fahrenheit or Celsius. To convert from one to the other, press and hold the UP/DOWN Temp/Timer buttons at the same time, for 3 seconds.

AIR DIRECTIONAL LOUVERS

The louvers will allow you to direct the air flow Up or Down and Left or Right throughout the room as needed. Pivot horizontal louvers until the desired Up/Down direction is obtained. Move the Lever(s) from side to side until the desired Left/Right direction is obtained.

Installation Instructions

1. PREPARE THE WINDOW

Lower sash must open sufficiently to allow a clear vertical opening (see dimension H in 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.

CAUTION When handling unit, be careful to avoid cuts from sharp metal edges and aluminum fins on front and rear coils.

2. PREPARE THE AIR CONDITIONER

Before installing the unit, the top rail must be assembled on the unit

A: Remove the air conditioner from the carton and place on a flat surface.

D: Secure the top rail to the unit with the 3/8” (9.5mm) screws as shown in Fig. C.

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

3. INSTALL THE ACCORDION PANELS

NOTICE The Top rail and Sliding Panels on each side are offset to provide the proper pitch to the rear of 5/16” (8mm). This is necessary for proper condensate management and drainage. If you are not using the side panels for any reason, this pitch to the rear must be maintained.

1. Place unit on the floor, a bench or a table. There is a left and right side accordion 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. 2. 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.

NOTICE If storm window blocks AC, see Fig. 11.

4. INSTALL AIR CONDITIONER

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. 5). Carefully close the window behind the top rail of the unit.

NOTICE Check that air conditioner is tilted back per dimension H (Fig. 5) (tilted about 3° to 4° downward to the outside). After proper installation, condensate should not drain from the overflow drain hole during normal use. Adjust the slope if otherwise.

3. Extend the side panels out against the window frame (Fig. 6).

5. SECURE AIR CONDITIONER

A. Place the frame lock between the frame extensions and the window sill as shown (Fig. 7A for Wooden windows), (Fig. 7B for Vinyl-Clad windows). Drive 3/4” (19 mm) or 1/2” (12.7 mm) locking screws through the frame lock and into the sill.

NOTE: To prevent window sill from splitting, drill 1/8” (3 mm) pilot holes before driving screws.

B1: For wooden windows: Drive 1/2” (12.7 mm) locking screws through the frame lock and into the sill (Fig. 8A).

NOTE: To prevent window sill from splitting, drill 1/8” (3mm) pilot holes before driving screws. Drive 1/2” (12.7mm) locking screws through frame holes into window sash (Fig. 8B/8C).

B2: For Vinyl-Clad windows: Drive 1/2” (12.7 mm) locking screws through the top rail and into the window sash (Fig. 8B/8C).

NOTE: Before driving the screws, drill 5 holes into the window through the holes of the top rail and side panel frames as shown (Fig. 8B/8C).

C. Secure lower sash in place by attaching the sash lock with the 3/4” (19 mm) or 1/2” (12.7 mm) screw as shown (Fig. 9).

D. Cut Window sash seal foam and insert it in the space between the upper and lower sashes (Fig. 10).

If AC is Blocked by Storm Window

Add wood as shown in Fig. 11, or remove storm window before air conditioner is installed.
