Final Process - Trane Voyager WS 150-24 Installation, Operation And Maintenance Manual

WARNING
Hazardous Pressures!
If a heat source is required to raise the tank pressure
during removal of refrigerant from cylinders, use only
warm water or heat blankets to raise the tank
temperature. Do not exceed a temperature of 150°F. Do
not, under any circumstances apply direct flame to any
portion of the cylinder. Failure to follow these safety
precautions could result in a sudden rise of pressure
possibly resulting in a violent explosion which could
result in death or serious injury.
Do not heat the detergent-and-water solution above 150°F .
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.
b. the minimum nozzle spray angle is 15 degrees.
c. maintain a minimum clearance of 6" 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 status and check
system operation.
