It is recommended that air filters be changed or cleaned at least four times a year. More
frequent attention to filters is required if the air being handled by the unit is unusually dirty.
Air flow reduction, caused by the dirty air filters, will increase the discharge air temperature
and may cause unit cycling on the primary limit.
Filters (by others) should be serviced regularly and changed or washed when necessary to
maintain the required air throughput. In a dusty environment, filters may clog up in less than
one month.
