Annual Inspection
It is suggested that your unit be inspected by your dealer or
servicer once a year. It is advisable to have the outer case
removed and the unit thoroughly cleaned.
Note: The life of your unit may be greatly reduced if you live
in a salt air or other corrosive type environment. Under these
conditions, the unit should be removed from its case and
completely cleaned at least once a year. At that time any
scratches or blisters on the painted surfaces should be
sanded and repainted. Placing an algaecide tablet in the
outdoor side of the unit’s basepan is suggested in humid
areas where algae formation is common. We recommend the
following algaecide cleaners: PanGuard

on right side of filter into three slots on filter frame. Carefully
bow middle of filter until two tabs on filter can be inserted into
two slots on filter frame. Relax bow.
Reinstall air filter by reversing removal procedure.
Front Grille and Cabinet Cleaning
Grille and cabinet may be cleaned with warm water and mild
soap or detergent. Cleaning and polishing compounds are not
recommended, as they may damage plastic surfaces.
Air Filter Cleaning
A dirty air filter reduces operating efficiency of unit. Filter
should be inspected at least once every week during opera-
tion. Clean filter with vacuum cleaner or wash in warm water
and mild detergent. Filter should be thoroughly dried before
replacing in unit. Do not operate unit without filter in place.
Fan Motor Care
The fan motor is permanently lubricated for long life. There is
no need to oil the motor.

2. Remove air filter by sliding to left.

front.
4. If the unit has a screw holding the basepan clip to the
chassis, remove the screw.
CAUTION
To reduce the risk of personal injury, be sure to
have sufficient help when moving your unit. A
room air conditioner can weigh between 70 and
240 pounds.
5. Using basepan handle, pull chassis straight out, slowly
and evenly, until approximately 9-12 inches extends from
outer case. Use both hands to grasp basepan and pull
