Air Conditioner Features – MAW05M Model

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 to maintain the desired set temperature. Rotate the thermostat selector clockwise for higher cool settings. Higher cool settings will provide a lower room temperature. Rotate the thermostat selector counterclockwise for lower cool settings. Lower cool settings will provide a 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 a minimum cooling effect and airflow.

FAN MODE

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

ELECTRONIC CONTROL OPERATING INSTRUCTIONS

TO TURN THE UNIT ON OR OFF:
Press the ON/OFF button to turn the unit on or off.

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

TO CHANGE TEMPERATURE SETTING:
Press the Power button to turn the 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. In dry mode, the fan operates on Low speed automatically.

SLEEP FEATURE:

Press the 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 the Energy Saver button to initiate this function. This function is available on COOL, DRY, and 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 until the ComfortSense button is pressed again. If the unit does not receive the ComfortSense signal during any 7-minute 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 in 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 the 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 in 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 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 for 0.5 hour, operate for 0.5 hour, and then stop.

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 the error repeats, call for service.
NOTE: In Fan only mode, if the room temperature is 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 the error repeats, call for service.

NOTICE: If the unit shuts off unexpectedly due to a 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.

Tools You Will Need

Tools You May Use

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.
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.
- B: Remove top rail from the packaging material as shown in Fig. A.
- C: Align the hole in the top rail with those in the top of the unit as shown in Fig. B.
- D: Secure the top rail to the unit with the 3/8” (9.5mm) screws as shown in Fig. C.
INSTALL THE ACCORDION PANELS
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.
INSTALL AIR CONDITIONER
- 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.
- Extend the side panels out against the window frame (Fig. 6).
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.
- 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).
  - 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).
- 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).
- Cut the Window sash seal foam and insert it in the space between the upper and lower sashes (Fig. 10).

If AC is Blocked by a Storm Window

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

Removing AC From the Window

Turn the AC off, and disconnect the power cord.
Remove the sash seal from between the windows, and unscrew the sash lock.
Remove screws installed through top rail and side panel frames.
Close (slide) the side panels into the rails.
Keeping a firm grip on the air conditioner, raise the sash and carefully remove.
Be careful not to spill any condensate while lifting the unit from the window. Store parts WITH the air conditioner.

Care and Cleaning

Air Filter Cleaning

The air filter should be checked at least once a month to see if cleaning is necessary. Trapped particles in the filter can build up and cause an accumulation of frost on the cooling coils.

Push the vent handle to the closed position (where applicable). Open the front panel.
Take the filter by the center and pull up and out.
Wash the filter using liquid dishwashing detergent and warm water. Rinse filter thoroughly.
Gently shake excess water from the filter. Be sure the filter is thoroughly dry before replacing.
You may also vacuum the filter clean rather than washing.

Cabinet Cleaning

Be sure to unplug the air conditioner to prevent a shock or fire hazard. The cabinet and front may be dusted with an oil-free cloth or washed with a cloth dampened in a solution of warm water and mild liquid dishwashing detergent. Rinse thoroughly and wipe dry.
Never use harsh cleansers, wax, or polish on the cabinet front.
Be sure to wring excess water from the cloth before wiping around the controls. Excess water in or around the controls may cause damage to the air conditioner.
Plug in the air conditioner.

Winter Storage

If you plan to store the air conditioner during the winter, remove it carefully from the window according to the installation instructions. Cover it with plastic or return it to the original carton.
