4. Mix the detergent with water according to the manufacturer’s instructions. If desired, heat the
solution to 150° F maximum to improve its cleansing capability.
5. Pour the cleaning solution into the sprayer. If a 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. Maintain a minimum clearance of 6" between the sprayer nozzle and the coil.
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 Steps 7 and 8.
9. Reinstall all of the components and panels removed in Step 1; then restore power to the unit.
10. With a fin comb, straighten any coil fins which were inadvertently bent during the cleaning
process.
Fall Restraint
WARNING
Falling Off Equipment!
This unit is built with fall restraint slots located on unit top that must be used during servicing.
This slot is to be used with fall restraint equipment that will not allow an individual to reach the
unit edge, but will NOT prevent falling to the ground, for they are NOT designed to withstand
the force of a falling individual. Failure to wear a fall restraint equipment and use the fall
restraint slots could result in death or serious injury.
The fall restraint is located approximately 3 feet from the unit edge. Figure 58, p. 124
