and dirt into the coil. This will make cleaning
efforts more difficult. Surface loaded fibers must
be completely removed prior to using low
velocity clean water rinse.
A monthly clean water rinse is recommended for
coils that are applied in coastal or industrial
environments to help to remove chlorides, dirt,
and debris. It is very important when rinsing, that
water temperature is less than 130°F and pressure
is less than 100 psig to avoid damaging the fin
edges. An elevated water temperature (not to
exceed 130°F) will reduce surface tension,
increasing the ability to remove chlorides and
dirt.
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:
GulfClean ™ Coil Cleaner ; AAON PN:

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
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
