This manual must be left with the homeowner for future reference.
CAUTION
Save these instructions for future reference
These instructions are intended as a general guide and
do not supersede national, state or local codes in any
way.
NOTE TO INSTALLING DEALER
These instructions and warranty are to be given to the
owner or displayed near the indoor air handler unit.
Failure to follow instructions will cause damage to the
unit.
This unit is equipped with an aluminum coil. Aluminum
coils may be damaged by exposure to solutions with
a pH below 5 or above 9. The aluminum coil should
be cleaned using potable water at a moderate pressure
(less than 50psi). If the coil cannot be cleaned using
water alone, it is recommended to use a coil cleaner
with a pH in the range of 5 to 9. The coil must be rinsed
thoroughly after cleaning.
In coastal areas, the coil should be cleaned with potable
water several times per year to avoid corrosive buildup
(salt).
