2. Use a soft brush or vacuum to remove base debris or
surface loaded fibers from both sides of the coil.
Note: When possible, clean the coil from the opposite
direction of normal air flow (inside of unit out) to
push debris out.
3. Using a sprayer and water ONLY, clean the coil
following the guidelines below.
a. Sprayer nozzle pressure should not exceed 580 psi.
b. The maximum source angle should not exceed 25°
to the face of the coil. See
spray the microchannel perpendicular to face of the
coil.
c. Spray nozzle should be approximately 1"-3" from
the coil surface.
d. Use at least a 15º fan type of spray nozzle.

Note: To avoid damage from the spray wand contacting
the coil, make sure the 90º attachment does not
come in contact with the tube and fin as abrasion to
