Recommended Coil Cleaner
The following cleaning agent, when used in
accordance with
the
manufacturer’s
directions on the container for proper mixing
and cleaning, has been approved for use on
e-coated coils to remove mold, mildew, dust,
soot, greasy residue, lint,
and other
particulate:
Enviro-Coil Cleaner: AAON PN: V82540
GulfClean ™ Coil Cleaner; AAON PN:
G074480
Recommended Chloride Remover
GulfClean Salt Reducer™; AAON PN:
G074490
GulfClean Salt Reducer™ is used to remove
soluble salts from the e-coated coil, follow
the manufacturer’s instructions.
This
product is not intended for use as a
degreaser. Any grease or oil film must first
be removed with GulfClean ™ Coil Cleaner.
Remove Barrier - First ensure the power to
the unit is off and locked out. Clean the area
around the unit if needed to ensure leaves,
grass or loose debris will not be blown into
the coil. Soluble salts adhere themselves to
the substrate. For the effective use of this
product, the product must be able to come in
contact with the salts. These salts may be
beneath any soils, grease or dirt; therefore,
these barriers must be removed prior to
application of this product. As in all surface
preparation, the best work yields the best
results.
Application - Apply GulfClean ™ Coil
Cleaner
directly
onto
the
substrate.
Sufficient
product
must
be
applied
uniformly across the substrate to thoroughly
wet out surface, with no areas missed. This
may be accomplished by use of a pump-up
sprayer or conventional spray gun. 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.
Allow the cleaning solution to soak for 5 to
10 minutes. Then move on to the exterior
using the same method.
Rinse - Using pressurized potable water such
as a garden hose, (< 100 psi), rinse the coils
and
continue
to
always
work
in
sections/panels.
Continue until all coil areas on the inside of
the unit have been rinsed.
Note: Coils must
always be cleaned / back flushed, opposite
of airflow to prevent impacting the dirt into
the coil.
Repeat these steps with GulfClean ™ Salt
Reducer. When finished replace 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. Condenser coil must 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 must be followed at
every cleaning interval. Using improper
cleaning technique or incorrect chemicals
will
result
in
coil
damage,
system
performance fall off, and potentially leaks
requiring coil replacement.
Documented
routine
cleaning
of
microchannel coils with factory provided e-
coating is required to maintain coating
warranty coverage. Use the E-Coated Coil
Cleaning section for details on cleaning e-
coated coils.
Field
applied
coil
coatings
are not
recommended with microchannel coils.
