compressor plate and compressor access panel.
5. For Sizes 07- - 12: Remove fastener holding coil sec-
tions together at return end of condenser coil. Care-
fully separate the outdoor coil section 3 to 4 in.
(7.6- - 10 cm) from the inner coil section. See Fig. 14.
6. Clean the outer surfaces with a stiff brush in the nor-
mal manner. Use a water hose or other suitable equip-
ment to flush down between the 2 coil sections to re-
move dirt and debris.
7. Secure inner and outer coil rows together with a
field- - supplied fastener.
8. Reposition the outer coil section and remove the coil
corner post from between the top panel and center

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
C08206
the fin/tube interface where dissimilar materials are in
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.
Totaline Environmentally Sound Coil Cleaner
Application Instructions:

glasses and gloves, is recommended during mixing
and application of Totaline Environmentally Sound
