Filter Replacement
Monthly air filter inspection is required to
maintain optimum unit efficiency.
It is strongly recommended that filter media
be replaced monthly. Filters are located
upstream of the evaporator coil in the filter
and economizer section. Open access door
and pull filters straight out to inspect all of the
filters. Replace filters with the size indicated
on each filter or as shown in the tables below.
Arrow on the replacement filters must point
towards the blower. (RAB = Return Air
Bypass, PE = Power Exhaust and PR = Power
Return)
