6. Remove the upper and lower 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. 18.
9. Clean the outer coil surface to remove surface loaded fibers
or dirt. See “Remove Surface Loaded Fibers” on page 10 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 lower
and upper coil clips. Reinstall the top panel and replace all
screws.

Instructions
1. Proper eye protection such as safety glasses is recom-
mended 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

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 cor-
rosion of unit parts.
Harsh chemicals, household bleach or acid or basic clean-
ers 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 inter-
face where dissimilar materials are in contact. If there is
dirt below the surface of the coil, use the Totaline environ-
mentally balanced coil cleaner.
