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, (< 689.5 kpa [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.
