middle). Work in sections/panels
ensuring that all areas are covered and
kept wetted.
7. Apply the cleaner to unit interior air
exiting side coil surfaces first. Work
in sections/panels moving side to side
and from top to bottom.
8. Generously soak coils by spraying
cleaner directly on and into the fin
pack section to be cleaned and allow
the cleaning solution to soak for 5 to
10 minutes.
9. Using pressurized potable water,
(<100 psi), rinse the coils and
continue
to always work in
sections/panels. Start at the top of the
coil and slowly move vertically
downward to the bottom. Then,
staying in the same vertical area,
slowly move back up to the top where
you started. Now move over slightly
overlapping the area just completed
and repeat above. Continue until all
coil areas on the inside of the unit
have been rinsed.
10. Complete steps 5-9 for the exterior air
entering side of the coils.
11. Final rinse – Now complete a quick
rinse of both sides of the coil
including the headers, piping, u-
bends and hairpins.
12. If the coil has a drain pan or unit floor
that is holding rinse water or cleaner,
extra time and attention will need to
be taken in those areas to ensure a
proper rinse has been completed.
Warranty Protection – Step 2
Complete the coil chloride (salt) removal
following these steps:
1. CHLOR*RID® is a concentrate to be
used
for both normal inland
applications at a 100:1 mix ratio OR
for severe coastal applications 50:1
mix ratio with potable water, (2.56
ounces of Chlor*rid to 1 gal of water).
Using a pump up sprayer, fill to the
appropriate level with potable water
and add the correct amount of
CHLOR*RID® salt remover leaving
room for the pump plunger to be
reinserted.
2. Apply CHLOR*RID® to all external
coil surfaces using a pressurized
pump up sprayer maintaining a good
rate of pressure and at a medium size
nozzle spray, (not a solid stream and
not a wide fan but somewhere in the
middle). Work in sections/panels
ensuring that all areas are covered and
kept wetted.
3. Generously soak coils by spraying
CHLOR*RID® directly on and into
the fin pack section. Let stand for 5 to
10 minutes keeping the area wetted.
Do not allow to dry before rinsing.
4. Using pressurized potable water,
(<100 psi), rinse the CHLOR*RID®
and dissolved chlorides/salts off of
the coils continuing to always work in
sections/panels.
5. Starting at the top of the coil, begin
rinsing the coil from side to side until
you reach the bottom. Repeat as many
times as is necessary to ensure all coil
sections/panels have been completed
and are thoroughly rinsed.
6. Reinstall all panels and tops that were
removed.
Microchannel Coil Cleaning
Cleaning microchannel coils is necessary in
all locations. In some locations it may be
necessary to clean the coils more or less often
than recommended. In general, a condenser
coil should be cleaned at a minimum of once
a year. In locations where there is commonly
debris or a condition that causes dirt/grease
build up it may be necessary to clean the coils
more often. Proper procedure should be
followed at every cleaning interval. Using
improper cleaning technique or incorrect
