• poor quality water for cleaning
Totaline environmentally sound coil cleaner is nonflammable,
hypo-allergenic, non-bacterial, and a USDA accepted biode-
gradable agent that will not harm the coil or surrounding com-
ponents such as electrical wiring, painted metal surfaces, or in-
sulation. Use of non-recommended coil cleaners is strongly
discouraged since coil and unit durability could be affected.
One-Row Coil
Wash coil with commercial coil cleaner. It is not necessary to
remove top panel.
Two-Row Coils
Clean coil as follows:
1. Turn off unit power, tag disconnect and lock.
2. Remove top panel screws on condenser end of unit.
3. Remove condenser coil corner post. See Fig. 8. To hold
top panel open, place coil corner post between top panel
and center post. See Fig. 9.

Fig. 9 — Propping Up Top Panel
4. Remove screws securing coil to compressor plate and
compressor access panel.
5. Remove fastener holding coil sections together at return
end of condenser coil. Carefully separate the outer coil
section 3-in. to 4-in. from the inner coil section. See
Fig. 10.
Fig. 10 — Separating Coil Sections
6. Use a water hose or other suitable equipment to flush
down between the 2 coil sections to remove dirt and
debris. Clean the outer surfaces with a stiff brush in the
normal manner.
7. Secure inner and outer coil rows together with a field-sup-
plied fastener.
8. Reposition the outer coil section and remove the coil cor-
ner post from between the top panel and center post. Rein-
stall the coil corner post and replace all screws.
Totaline Environmentally Sound Coil Cleaner Application
Equipment
• 2 1 / gallon garden sprayer
2
• Water rinse with low velocity spray nozzle
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 sound
coil cleaner.
UNIT DAMAGE HAZARD
Failure to follow this caution may result in reduced unit
performance or unit shutdown.
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.
