Do not heat the detergent-and-water
solution above 150
o F (65.6 o
C). Hot
liquids sprayed on the exterior of the coil
will raise the coil’s internal pressure and
may cause it to burst. Failure to follow
proper procedures can result in personal
illness or injury or severe equipment
damage.
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 (41.4 bar).
b. the minimum nozzle spray angle
is 15 degrees.
c. maintain a minimum clearance of 6"
(152.4 mm) between the sprayer
nozzle and the coil.
d. spray the solution perpendicular
(at 90 degrees) 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 Steps 6
and 7.
9. Reinstall all of the components and
panels removed in Step 1 and any
protective covers installed in step 2.
10. Restore the unit to it’s operational
