INSTALLATION

How to Install the Unit

1. To prevent vibration and noise, make sure the unit is installed securely and firmly.

2. Install the unit where the sunlight dose not shine directly on the unit.

3. The outside of the cabinet must extend out- ward for at least 12" and there should be no obstacles, such as a fence or wall, within 20" from the back of the cabinet because it will prevent heat radiation of the condenser. Restriction of outside air will greatly reduce the cooling efficiency of the air conditioner.

CAUTION All side louvers of the cabinet must remain exposed to the outside of the structure.

4. Install the unit slightly tilted so the back is slightly lower than the front (about 1/2"). This will force condensed water to flow to the outside.

5. Install the unit with the bottom between 30"-60" above the floor level.

Window Requirements

• This unit is designed for installation in standard double hung windows with actual opening widths from 27" to 39". The top and bottom window sashes must open sufficiently to allow a clear vertical opening of 16" from the bottom of the upper sash to the inside sill.
• The height offset between the inside sill and outside sill must be less than 1 1⁄4".

NOTE

All supporting parts should be secured to firm wood, masonry, or metal.

Preparation of Cabinet

1. Remove 4 screws which fasten the cabinet at both sides and at the back. (Keep the screws for later use.)

2. Slide the unit from the cabinet by gripping the base pan handle and pulling forward while bracing the cabinet.

CAUTION

• The unit is heavy. To prevent injury, use proper lifting techniques when pulling unit forward from cabinet. Obtain assistance from another person if possible.

3. Cut the window sash seal (Foan-PE) to the proper length. Peel off backing and attach the adhesive-backed foam to the underside of the window sash and the bottom of the window frame.

4. Insert the lower curtain panel guides into the bottom of the cabinet. Insert the guides so that the flange faces to the rear of the cabinet.

5. Insert the top and bottom rails of the curtain panels into the upper and lower panel guides.

CAUTION The lower panel guides are easily broken. Be careful with them when installing the cabinet.

6. Fasten the curtain panels to the unit with 8 type A screws.

Cabinet Installation

1. Open the window. Mark a line on the center of the inside sill.

Carefully place the cabinet in the window and align the center hole on the cabinet bottom front with the bracket using a carriage bolt and a lock nut.

2. Pull the bottom window sash down behind the upper guide until they meet.

NOTE Do not pull the window sash down so tightly that the movement of the curtain panels is restricted.

3. Lossely assemble each sill support.

NOTE If the distance to the outer window sill is not that deep, you may not need the bolt and nut.

4. Use 2 type A screws to attach a sill support to the cabinet track hole o one side. Use the cabinet track holes that will place the sill support nearest to the outer edge of the sill. Repeat with the second sill support on the opposite side of the cabinet.

5. Install the cabinet with a slight tilt (about ½) downward on the outside. Use a bolt and nut to adjust the tilt of the cabinet.

CAUTION

• Do not drill a hole in the bottom pan. The product is designed to operate with approximately '1/2" of water in the bottom pan. There is no need to add water if the pan is dry.

6. Attach the cabinet to the inside sill bydriving 3 type B screws through the cabinet and into the sill.

NOTE Install the cabinet with a very slight downward tilt toward the outside.

CAUTION Do not drill a hole in the bottom pan. The product is designed to operate with approximately '1/2" of water in the bottom pan.

7. Pull each curtain panel out until it meets the window sash track. Pull the bottom window sash down behind the upper panel guide until they meet.

NOTE

Do not pull the window sash down so tightly that the movement of the curtain panels is restricted.

8. Use a screwdriver or power drill to attach the curtain panels to the window sashes by driving type C screws into the sashes through the cabinet holes shown in the figure below.

9. With the aid of an assistant, slide the unit into the cabinet. Reinstall the screws removed from the cabinet sides in step 1.

CAUTION

• The unit is heavy. Use an assistant to help lift the unit and set it in place. Lifting and maneuvering the unit by yourself could result in injury.
• Hold the unit firmly in place until the window frameis lowered to meet the top surface of the unit directly behind the upper guide. If the unit falls from the window, it could cause personal injury orproperty damage.

10. Cut the non-adhesive foam strip to the proper length and insert it between the upper window sash and the lower window sash.

11. Attach the window locking bracket with a type C screw.

12. Before installing the front grille, pull out the vent control lever located above the unit control knobs as shown.

13. Cut the adhesive-backed heatproof foam to match the size of the curtain panels. Remove the backing from the heatproof foam and attach it to the curtain panels.

NOTE Heatproof foam improves the cooling capability of the air conditioner.

14. Connect the housing

15. Attach the front grille to the cabinet by inserting the tabs the grille into the slots on the front the cabinet.Push the grille in until it snaps into place.

NOTE Guide the lever carefully through the grille as you push it in.

16. Take out the air filter and secure it with 2 type A screws through the front grille. (These 2 Type A screws are packaged by bag on the Front Grille.)

OPERATION

Control Panel and Remote Control

1. Power

Press to turn the air conditioner ON or OFF.

2. Fan Speed

Press to set the fan speed to Low (F1), Medium (F2), or High (F3).

3. Delay ON/OFF Timer

• Delay ON - When the air conditioner is off, set it to automatically turn on from 1 to 24 hours later, at its previous mode and fan settings.
• Delay OFF - When the air conditioner is on, set it to automatically turn off from 1 to 24 hours later.

NOTE •Each press of the Timer button advances the timer by 1 hour. After the last press the display returns to the temperature setting.

4. Operation Mode

Press the Mode button to cycle between 4 types of air conditioner operation: Energy Saver / Cool / Fan / Dry.

• Energy Saver - In this mode the compressor and fan turn off when the set temperature is achieved. Approximately every 3 minutes the fan turns on to allow the unit sensor to accurately determine if more cooling is needed.
• Cool - This mode is ideal on hot days to cool and dehumidify the room quickly. Use the Temp buttons to set the desired room temperature and use the Fan Speed button to set the desired fan circulation speed.
• Fan - In this mode the fan circulates air but the compressor does not run. Use the Fan Speed button to set fan speed to High, Medium or Low. In this mode, you cannot adjust the set temperature.
• Dry - This mode is ideal for rainy and damp days to dehumidify the room rather than cooling it significantly. Humidity is removed from the room by the combination of compressor operation and the fan speed fixed at Low. The compressor and fan turn off once the set temperature is reached. Fan speed cannot be adjusted in Dry mode.

5. Temperature Control

The thermostat monitors room temperature to maintain the desired temperature. The thermostat can be set between 60 °F-86 °F (16 °C-30 °C). Press arrows to increase or decrease temperature setting.

6. Remote Control Sensor

7. Clean Filter

The Clean Filter LED lights up to notify you that the filter needs to be cleaned. After cleaning the filter, press Temp Ʌ and together on the control panel to turn off the Clean Filter light.

NOTE

• The filter reset must be done using the control panel, not the remote control.
• This feature is a reminder to clean the air filter for more efficient operation. The LED light turns on after 250 hours of operation.

NOTE

• Auto Restart: If the air conditioner turns off due to a power outage, it will restart automatically once the power is restored, with the same settings as were set before the unit turned off.
• Energy Saver: The unit defaults to the Energy Saver mode each time the unit is switched on except in Fan mode or when power is restored after an electrical power outage.
• The remote control will not function properly if the AC infrared sensor is exposed to direct light or if there are obstacles between the remote controller and the air conditioner.

• Do not use a rechargeable battery. Make sure that the battery is new.
• In order to prevent discharge, remove the battery from the remote control if the air conditioner is not going to be used for an extended period of time.
• Keep the remote control away from extremely hot or humid places.
• To maintain optimal operation of the remote control, the remote sensor should not be exposed to direct sunlight.

MAINTENANCE

Air Filter

Check the air filter at least twice a month to see if cleaning is necessary. Trapped particles in the filter can build up and block the airflow, reducing cooling capacity and causing an accumulation of frost on the evaporator.

Cleaning the Air Filter

1. Remove the air filter from the front grille by pulling the filter forward and then up slightly.

2. Wash the filter using lukewarm water below 40 °C (104 °F).

3. Gently shake the excess water from the filter and replace.

Clenaing the Air Conditioner

• Wipe the front grille and inlet grille with a cloth dampened in a mild detergent solution.
• Wash the cabinet with mild soap or detergent and lukewarm water, the polish using liquid appliance wax.

NOTE

• To ensure continued peak efficiency, the condenser coils (outside of unit) should be checked periodically and cleaned if clogged with soot or dirt from outside air.
• For repair and maintenance, contact an Authorized Service Center. See the warranty page for details or call 1-800-243-0000. Have your model number and serial number available. They should be written on page 23 of this manual.
