IMPORTANT:
UNPACKING THE AIR CONDITIONER
Remove and store packing materials for reuse. Remove any shipping tape before using the air conditioner. If the tape leaves behind any adhesive. rub a small amount of liquid dish soap onto it and wipe with a damp cloth. Do
NOT use sharp instruments. alcohol. thinners. or abrasive cleaners to remove adhesive. They could damage the finish.
OPERATING TEMPERATURE
Inserting Batteries
If the display screen of the remote control begins to fade, replace the batteries. Insert AAA (1.5 V) batteries before using the remote control.


NOTE

NOTE The length of the flexible vent hose is specially designed according to the specification of this product. Do not replace or extend it with a hose that is not specifically designed for use with this product as this could cause malfunction.


• Round Type
Insert the mounting bracket and rotate it to lock it in place.

• Square Type
Insert the mounting bracket and slide it to lock it in place.

The window installation kit allows you to install the air conditioner in most vertical-sliding windows 18″ to 50″ wide, or horizontal-sliding windows from 18″ to 50″ high.

1. Select the panels required based on the window opening, as shown above.
2. For longer window openings, assemble and adjust the panels to fit the window opening. Use type A screws (included) to fix the panels together at the proper length.


For an 18″ window opening, use the window vent panel (Panel A) by itself.
Fig. a

For window openings from 27″ to 34″, use the window vent panel (Panel A) and extension Panel D
Fig. c


For window openings from 19″ to 25″, use the window vent panel (Panel A) and extension Panel B.
Fig. b

For window openings from 35″ to 50″, use the window vent panel (Panel A) and extension Panel C and Panel D
Fig. d

1. Attach the long adhesive foam weather seals to the top and bottom sides of the window vent panel assembly. Attach the short foam weather seals to the right and left sides of the panel assembly. (Attaching the foam weather seals to the panel assembly rather than the window sash and frame makes for easier cleanup when removing the panel assembly.)

2. Insert the panel assembly in the bottom sash channel. Use care when installing the assembly, which will now fit very tightly in the opening. Close the sash tightly against the top of the panel assembly

3. If needed, install the included security bracket with type B screws.

4. Measure and cut the included non-adhesive foam to fit the window opening. Stuff it between the window sashes to prevent air and insects from getting into the room.

5. Align the tabs on the diffuser with the slots in the vent panel. Insert the diffuser into the opening in the vent panel and slide the diffuser all the way over to lock the tabs in place. Position the diffuser with the round opening above the bottom of the vent panel to avoid interference from the window sill.

6. Insert the type C screw in the hole in the diffuser to prevent the diffuser from sliding out of the vent opening. If the diffuser is positioned correctly, the screw should just clear the edge of the opening in the vent panel. You should not have to drill through the vent panel.
NOTE


CAUTION
• If you use the Heat mode, you must install the drain hose. If only the Cool mode is used, the drain hose is not needed.
• If the outside temperature is at or near freezing 32 °F (0 °C) follow the indoor drainage instructions.
• When the weather is above freezing, the unit can be set up to drain to the outside. Make sure the outlet of the hose is aimed away from nearby surfaces that could be stained or damaged by the draining water.
Indoor Drainage
1. To attach the drain hose, insert the connector into the pump drain port at the back of the unit until it snaps into place.
2. Place the other end of the drain hose in a bucket that holds at least 28 ounces. Remember to check and empty the bucket frequently to avoid overflows.
3. To detach the drain hose from the product, push the outer ring of the pump drain port in and pull the connector out.
NOTE
• Inserting the drain hose into the unit will automatically activate the drain function.

Outdoor Drainage
1. To attach the drain hose, insert the connector into the pump drain port at the back of the unit until it snaps into place.
2. Unscrew the nut at the bottom of the locking nut. Insert the locking nut into the hole in the front of the window vent panel and reassemble the nut. Unscrew the top part of the locking nut until you can easily insert the drain hose through the opening.
3. Make sure to insert the drain hose at least 8 inches (20 cm).
4. Turn the top of the locking nut to tighten it and secure the drain hose in place.
5. To detach the drain hose from the product, push the outer ring of the pump drain port in and pull the connector out.
NOTE
• Inserting the drain hose in the unit will automatically activate the drain function.

1. Remove the drain plug when using the Dry (dehumidifying) mode.
2. Install a 1/2" (12.7 mm) inside diameter garden hose (not provided) into the continuous drain port and place the open end of the hose over a floor drain or bucket.

NOTE
• Install the garden hose when you need dehumidification in high humidity.
• This product has a self-evaporative system. The condensing water will be recycled to cool the condenser. This not only improves cooling efficiency, but also saves energy for you.
