coil, drain pan, and inside the bottom of the chassis are recommended
at least once a year, and more often if the equipment is operated
in a dusty or hostile environment. The outdoor coil is an aluminum
microchannel condensing coil with an anti-corrosion coating that
requires specific precaution when cleaning. It is recommended to
rinse the coil using a low pressure hose (less than 70 psi) to prevent
buildup of dirt and debris. Rinse from the outside of the coil in,
making sure to protect the condenser motor from water damage
during the cleaning process. Leaves, twigs, and other large debris
should be removed with a soft, non-metallic bristle brush prior to
rinsing of the coil to prevent debris from being forced between the
fins. Care should be taken not to use the brush horizontally across
the fins as they are easily damaged.
DO NOT USE CHEMICALS, HOUSEHOLD BLEACH, OR ACID
CLEANERS AS THEY WILL ACCELERATE CORROSION ON THE
COIL. AVOID USING PRESSURE WASHERS, HIGH PRESSURE
HOSES, OR HIGHLY COMPRESSED AIR TO CLEAN THE COIL.
DOING SO CAN PERMANENTLY DAMAGE THE COIL, REDUCE
UNIT PERFORMANCE, AND VOID THE WARRANTY.

cover must be reinstalled .
