Inspect and Clean Indoor Air Coil
Eventually, minor amounts of lint and dirt may pass
through the lter and collect on the indoor-air coil. These
minor accumulations can be carefully vacuumed away
with a brush attachment on a vacuum cleaner. Care must
be taken to avoid bending the aluminum ns on the coil.
Bent ns should be straightened using a special n tool
available from most HVAC supply depots.
Inspect Outdoor Air (OA) Intake and Exhaust
The unit’s outdoor-air intake and outdoor-air exhaust paths
must remain clear. Keep it free of all debris, snow, or ice.
The OA intake should also be kept free of obstructions.
Blocking the OA exhaust or OA intake opening will reduce
the efciency of your unit and could damage it.
Inspect and Clean Condensate Drain
The condensate drain must be routed to a suitable drainage
area. Check the unit condensate drain periodically. Keep
it free of anything that may block or impede the ow of
condensate water. If there is any accumulation of foreign
matter in the drain pipe, it should be removed and cleaned.
The entire drain line must be protected from freezing.
Warranty
All warranty service work must be done by an authorized
servicer. See Product Warranty, and consult your dealer or
contractor for details.
