Avoid the use of:
•
coil brighteners
•
acid cleaning prior to painting
•
high pressure washers
•
poor quality water for cleaning
Totaline environmentally sound coil cleaner is nonflamma-
ble, hypoallergenic, non bacterial, and a USDA accepted
biodegradable agent that will not harm the coil or surround-
ing components such as electrical wiring, painted metal sur-
faces, or insulation. Use of non-recommended coil cleaners
is strongly discouraged since coil and unit durability could
be affected.
Totaline Environmentally Sound Coil Cleaner
Application Equipment:
•
2-1/2 gallon garden sprayer
•
Water rinse with low velocity spray nozzle
CAUTION
UNIT DAMAGE HAZARD
Failure to follow this caution may result in corrosion 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 con-
tact. If there is dirt below the surface of the coil, use the
Totaline environmentally sound coil cleaner as described
above.
CAUTION
UNIT RELIABILTY HAZARD
Failure to follow this caution may 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.

3. Remove all surface loaded fibers and dirt with a vac-
NOTE: Use of a water stream, such as a garden hose,
against surface loaded coil will drive the fibers and dirt into
the coil, making cleaning efforts more difficult. Surface load-
ed fibers must be completely removed prior to using low ve-
locity clean water rinse.
4. Using a low velocity garden hose thoroughly wet
5. Mix Totaline environmentally sound coil cleaner in a
NOTE: Do NOT USE water in excess of 130°F (54°C), as
the enzymatic activity will be destroyed.
6. Thoroughly apply Totaline environmentally sound coil
7. Hold garden sprayer nozzle close to finned areas
8. Ensure cleaner thoroughly penetrates deep into
9. Interior and exterior finned areas must be thoroughly
