• For out-of-room operation, position the unit on a flat solid surface in an area
protected from rain and sun exposure such as a sunroom, veranda or hallway.
Do not operate the unit in extremely moist areas such as a sauna.
• The color of the unit can fade slightly due to sunlight.
• This unit is equipped with a thermal overload protector. This protects the
unit from overheating in extreme ambient conditions.
• Place the unit so that the air inlet is not blocked by furniture or curtains,
since this can negatively affect unit performance.
Place the unit in the shade if possible and in a cool place in order to increase
efficiency and to avoid overheating. If the unit is operated in extremely
high ambient temperatures, the unit may shut down automatically. If the
unit repeatedly shuts down, move the unit to a cooler location out of direct
REMOTE RECEIVER INSTALLATION
To enable the operation of the remote control while the unit is in out-of-room
operation, you must install the remote receiver into the window kit.
1. Punch out the circular plug from the window kit to create the remote
receiver hole. Keep the plug for possible later use.
2. Insert the receiver through the hole from the back of the window kit piece.
The receiver must face into the room being cooled and be positioned
higher than the main unit.
3. Remove the rubber cover from the remote receiver jack found near the top
front of the unit. Keep the cover for later use.
4. Attach the end of the receiver cable to the jack on the main unit. Arrange
the wire so it will not get damaged, stepped on or pinched.
When using the remote to control the unit, point the remote at the receiver in
the window kit. Reception is confirmed by a green LED flash in the receiver.

THE ROOM TEMPERATURE SENSOR. Use the MODE button to set the unit
function to COOLING. Adjust the set temperature using the TEMP up or
