CONDENSER COIL
Unfiltered air circulates through the unit's condenser coil and
can cause the coil's surface to become clogged with dust, dirt,
etc. To clean the coil, vertically (i.e., with the fins) stroke the
coil surface with a soft-bristled brush. Be sure to keep all vegetation
away from the condenser coil area.

MAINTENANCE PERFORMED BY SERVICEMAN-COOLING
SEASON
To keep your unit operating safely and efficiently, the manufacturer
recommends that a qualified serviceman check the entire system
at least once each year and any other time that you feel one is
needed. Your serviceman should examine these areas of your
unit:
● Filters
● Motors and drive system components
● Economizer gaskets (for possible replacement)
● Safety controls (for mechanical cleaning)
● Electrical components and wiring (for possible replace-ment
and connection tightness)
● Condensate drain (for cleaning)
● Unit duct connections (to see that they are physically sound
and sealed to the unit casing)
● Unit mounting support (for structural integrity)
● The unit (for obvious unit deterioration)
CAUTION CAUTION
Do not operate the unit without the evaporator fan access
panel in place. reinstall the access panel after performing
any maintenance procedures on the fan. operating the unit
without the access panel properly installed may result in
severe personal injury or death.
