• Remove panels or tops as required gaining access to the coil(s) to be cleaned.
• Using a pump up sprayer, fill to the appropriate level with potable water and add
the correct amount of approved cleaner as per manufacturer instructions leaving
room for the pump plunger to be reinserted.
NOTE:
Coils should always be cleaned / back flushed, opposite of airflow to
prevent impacting the direct into the coil
• If the coils have heavy dirt, fibers, grass, leaves, etc. on the interior or exterior face areas, a
vacuum and brush should be used to remove those surface contaminants prior to applying
cleaner. The interior floor, drain tray or pan areas should also be vacuumed.
Apply the mixed cleaner to 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.
• Apply the mixed cleaner to 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.
• Apply the cleaner to unit interior air exiting side of coil surfaces first. Work in
sections/panels moving side to side and from top to bottom.
• Generously soak coils by spraying cleaner directly on and into the fin pack section
to be cleaned and allow the cleaner solution to soak for 5 to 10 minutes.
• 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 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.
Complete steps below for the exterior air entering side of the coils
• Final rinse – Now complete a quick rinse of both sides of the coil including the
headers, piping, u-bends and hairpins.
• If the coil has a drain pan or unit flood 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.
