and damage to the unit.
Harsh chemicals, household bleach or acid or basic
cleaners should not be used to clean outdoor or indoor
coils of any kind. These cleaners can be very difficult
to rinse out of the coil and can accelerate corrosion at
the fin/tube interface where dissimilar materials are in
contact. If there is dirt below the surface of the coil,

described above.

UNIT DAMAGE HAZARD
Failure to follow this caution may result in reduced
unit performance.
High velocity water from a pressure washer, garden
