When the air conditioner has been performing its cooling operation and is turned off or set to the fan
position, wait at least 3 minutes before resetting to the cooling operation again.
• WARNING
To reduce the risk of fire, electric shock, or injury to persons, read the IMPORTANT SAFETY
INSTRUCTIONS before operating this appliance.
FUNCTION

HOW TO SECURE THE DRAIN PIPE
AIR FILTER CLEANING
In humid weather, excess water may cause the
BASE PAN to overflow. To drain the water, remove
the DRAIN CAP and secure the DRAIN PIPE to the
rear hole of the BASE PAN.
The air filter should be checked at least twice a month to see if cleaning is necessary. Trapped particles in
the filter will build up and block the airflow. This reduces the cooling capacity and also causes an
accumulation of frost on the cooling coils.
1. Open the inlet grille upward by pulling out the bottom of the inlet grille.
2. Remove the air filter from the front grille assembly by pulling the air filter up slightly.
3. Wash the filter using lukewarm water below 40°C (104°F).
4. Gently shake the excess water from the filter completely. Replace the filter.

INSTALLATION INSTRUCTIONS
SELECT THE BEST LOCATION
1. To prevent vibration and noise, make sure the
unit is installed securely and firmly
2. Install the unit where the sunlight does not
shine directly on the unit.
3. The outside of the cabinet must extend
outward 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.
WINDOW REQUIREMENTS
1. This unit is designed for installation in
standard double hung windows with actual
opening widths from 27" to 39".
The top and bottom window sash must open
sufficiently to allow a clear vertical opening of
16" from the bottom of the upper sash to the
window stool.
2. Install the unit a little slanted so the back is
slightly lower than the front(about 1/2").
This will help force condensed water to flow to
the outside.
3. Install the unit from the bottom about 30"~60"
above the floor level.
