4. Remove the compressor access panel to access the lower coil
clip. The condenser coil corner post may also be removed.
5. Remove the screws from both sides of the 4 coil retaining
clips on the hairpin end of the coil tube sheets. See Fig. 21.
6. Remove the 4 retaining clips.

7. Draw the inner coil inward to separate the coils for cleaning.
8. Insert a spacer (field-supplied) between the tube sheets to
hold the coils apart. See Fig. 22.
9. Clean the outer coil surface to remove surface loaded
fibers or dirt. See "Remove Surface Loaded Fibers" on
page 13 for details.
10. Use a water hose or other suitable equipment to flush down
between the 2 coil sections to remove dirt and debris. If a
coil cleaner is used be sure to rinse the coils completely
before reassembly.
11. Move the inner coil back into position. Reinstall the 4 coil
clips. Reinstall the top panel and replace all screws.

CAUTION
UNIT DAMAGE HAZARD
Failure to follow this caution may result in reduced unit
performance or unit shutdown.
High velocity water from a pressure washer or 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.
CAUTION
UNIT DAMAGE HAZARD
Failure to follow this caution may result in accelerated
corrosion of unit parts.
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, use the Totaline
environmentally balanced coil cleaner.
Totaline Environmentally Balanced Coil Cleaner Application
Equipment
• 2-1/2 gallon garden sprayer
• Water rinse with low velocity spray nozzle
Totaline Environmentally Balanced Coil Cleaner Application
Instructions
1. Proper eye protection such as safety glasses is recommended
during mixing and application.
2. Remove all surface loaded fibers and dirt with a vacuum
cleaner as described above.
3. Thoroughly wet finned surfaces with clean water and a low
velocity garden hose, being careful not to bend fins.
4. Mix Totaline environmentally balanced coil cleaner in a 2-1/2
gallon garden sprayer according to the instructions included
with the cleaner. The optimum solution temperature is 100°F.
NOTE: Do NOT USE water in excess of 130°F, as the enzy-
matic activity will be destroyed.
