Repairing or Replacing Cabinet Insulation
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.
WARNING
This product and/or the indoor unit it is matched with may
contain fiberglass wool.
Disturbing the insulation during installation,
maintenance, or repair will expose you to fiberglass wool
dust. Breathing this may cause lung cancer. (Fiberglass
wool is known to the State of California to cause cancer.)
Fiberglass wool may also cause respiratory, skin, and
eye irritation.
To reduce exposure to this substance or for further
information, consult material safety data sheets
available from address shown below, or contact your
supervisor.

Mat- 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.
