Quarterly cleaning is essential to extend the
life of an e-coated coil and is required to
maintain coating warranty coverage.
Coil cleaning shall be part of the unit’s
regularly scheduled maintenance procedures.
Failure to clean an
e-coated coil will void the
warranty and may result in reduced
efficiency and durability.
For routine quarterly cleaning, first clean the
coil with the below approved coil cleaner.
After cleaning the coils with the approved
cleaning agent, use the approved chloride
remover to remove soluble salts and
revitalize the unit.
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
High velocity water from a pressure
washer or compressed air must only
be used at a very low pressure to
prevent fin and/or coil damages. The
force of the water or air jet may bend
the fin edges and increase airside
pressure
drop. Reduced unit
performance or nuisance unit
shutdowns may occur.
CAUTION
Harsh chemicals, household bleach,
or acid cleaners must not be used to
clean outdoor or indoor e-coated coils.
These cleaners can be very difficult to
rinse out of the coil and can accelerate
corrosion and attack the e-coating. If
there is dirt below the surface of the
coil, use the recommended coil
cleaners.
CAUTION
