UNIT DAMAGE HAZARD
Failure to follow this caution can result in corrosion
and damage to the unit.
Harsh chemicals, household bleach, 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
C08206
contact. If there is dirt below the surface of the coil,
use the Totaline Environmentally Sound Coil Cleaner
as described below.
UNIT DAMAGE HAZARD
Failure to follow this caution can result in reduced
unit performance.
High velocity water from a pressure washer, garden
hose, or compressed air should never be used to clean
a coil. The force of the water or air jet will bend the
fin edges and increase airside pressure drop.
