Professional Maintenance
Failure to follow instructions will cause damage to the
unit.
This unit is equipped with an Omniguard
TM
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).
NOTICE
Homeowner Maintenance
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
•
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 air flow. 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.
