4. Mix the detergent with water according to the
manufacturer’s instructions. If desired, heat the
solution BUT DO NOT EXCEED 150ºF maximum to
improve its cleansing capability.
5. Pour the cleaning solution into the sprayer. If a high-
pressure sprayer is used:
a. do not allow sprayer pressure to exceed 600 psi.
b. the minimum nozzle spray angle is 15°.
c. maintain a minimum clearance of 6 in. between the
sprayer nozzle and the coil.
d. spray the solution perpendicular (at 90°) to the coil
face.
6. Spray the leaving-airflow side of the coil first; then
spray the opposite side of the coil. 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 Step 6 and Step 7.
9. Reinstall all of the components and panels removed in
Step 1 and any protective covers installed in Step 2.
