high-pressure sprayer is used:
a. The minimum nozzle spray angle is 15 degrees.
b. Do not allow sprayer pressure to exceed 600 psi.
c. Spray the solution perpendicular (at 90 degrees)
to the coil face.
d. For evaporator and reheat coils, maintain a
minimum clearance of 6" between the sprayer
nozzle and the coil. For microchannel condenser
coils, optimum clearance between the sprayer
nozzle and the microchannel coil is 1"-3".
6. Spray the leaving-airflow side of the coil first; then
spray the opposite side of the coil. For evaporator
and reheat coils, allow the cleaning solution to
stand on the coil for five minutes.
7. Rinse both sides of the coil with cool, clean water.
8. Inspect both sides of the coil; if it still appears to be
dirty, repeat Steps 6 and 7.
9. Reinstall all of the components and panels removed
in Step 1; then restore power to the unit.
10. For evaporator and reheat coils, use a fin comb to
straighten any coil fins which were inadvertently
bent during the cleaning process.

Steam or Hot Water Coils

To clean a steam or hot water coil, use a soft brush, a
steam-cleaning machine, and water.
1. Verify that switches 1S1 and 1S70 are turned
"OFF", and that the main unit disconnect is locked
open.

2. Remove enough panels and components from the
unit to gain sufficient access to the coil.
3. Straighten any bent coil fins with a fin comb. (Use
the data in to determine the appropriate fin comb
size.)
4. Remove loose dirt and debris from both sides of the
coil with a soft brush.
5. Use the steam-cleaning machine to clean the
leaving-air side of the coil first; start at the top of the
coil and work downward; then clean the entering-
air side of the coil, starting at the top of the coil and
working downward.

6. Check both sides of the coil; if it still appears dirty,
repeat Step 5.
7. Reinstall all of the components and panels removed
in Step 2; then restore power to the unit.
