ATTACH CEILING GRILL
1. Position the grill next to the interior frame and attach it with the 4 provided screws.
2. Install the filter on the air intake grill section.
3. Snap the intake grill section onto the main grille.
MAINTENANCE
1. AIR FILTER:
Remove the return air filter (after every 30 days of use) located above the removable air
intake grill. Wash the filter with soap and warm water, let dry and then reinstall.
Note: Never run the air conditioner without returning air filter in place. This may plug the
unit evaporator coil with dirt and may substantially affect the performance of the unit.
2. Air Return Grill:
Clean panel and control panel with a soft cloth dampened with a mild detergent. Never
use furniture polish or harsh chemicals.
3. FAN MOTOR:
Factory lubricated and requires no service under normal use.
4. FROST FORMATION ON COOLING COIL:
Under certain conditions, frost may form on the evaporator coil. If this should occur,
inspect the filter and clean if dirty. Make sure air louvers are not obstructed. Air
conditioners have a greater tendency to frost when the outside temperature is relatively
low. This may be prevented by adjusting the thermostat control knob to a warmer setting
(counter clockwise).
