Maintenance
• Inspect air filters at least once a month and replace or
clean as required. Dirty filters are the most common
cause of inadequate heating or cooling performance.
• Replace disposable filters. Cleanable filters can be
cleaned by soaking in mild detergent and rinsing with
cold water.
• Install new/clean filters with the arrows on the side
pointing in the direction of airflow. Do not replace a
cleanable (high velocity) filter with a disposable (low
velocity) filter unless return air system is properly sized
for it.
• If water should start coming from the secondary drain
line, a problem exists which should be investigated and
corrected. Contact a qualified service technician.
Cabinet Insulation
Matte- or foil-faced insulation is installed in indoor equipment
to provide a barrier between outside air conditions
(surrounding ambient temperature and humidity) and the
varying conditions inside the unit. If the insulation
barrier is damaged (wet, ripped, torn or separated from the
cabinet walls), the surrounding ambient air will affect the
inside surface temperature of the cabinet. The temperature/
humidity difference between the inside and outside of the
cabinet can cause condensation on the inside or outside
of the cabinet which leads to sheet metal corrosion and
subsequently, component failure.
REPAIRING DAMAGED INSULATION
Areas of condensation on the cabinet surface are an
indication that the insulation is in need of repair.
If the insulation in need of repair is otherwise in good
condition, the insulation should be cut in an X pattern, peeled
open, glued with an appropriate all-purpose glue and placed
back against the cabinet surface, being careful
to not overly compress the insulation so the insulation can
retain its original thickness. If such repair is not possible,
replace the insulation. If using foil-faced insulation, any cut,
tear, or separations in the insulation surface must be
taped with a similar foil-faced tape.

Repairing Insulation
Do not operate system without a filter. A filter is
required to protect the coil, blower, and internal parts
from excessive dirt and dust. The filter is placed in the
return duct by the installer.
IMPORTANT
DAMAGED INSULATION MUST BE REPAIRED OR
REPLACED before the unit is put back into operation.
Insulation loses its insulating value when wet, damaged,
separated or torn.
