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).
