EXTERNAL FILTER MAINTENANCE
Aluminum mesh 2 inch filters are located in
the supply weatherhood on outdoor units.
Filters should be checked and cleaned on a
regular basis for best efficiency. The
frequency of cleaning depends upon the
cleanliness of the incoming air.
To remove these filters, pull the side access
panel off and simply slide the filters out of the
weatherhood.
Clean filters by rinsing with a mild detergent in
warm water. After the filters are dry, an
adhesive spray available at most filter
distributors may be applied to increase filter
efficiency.
