WARNING: Allow only qualified personnel to perform the following tasks.
Follow the safety instructions in this document and all other related
documentation.
Initial Canopy Conditioning
Perform this procedure on new canopies before initial startup. This
procedure removes any oils or other contaminants from the canopy, making
the canopy easy to clean and reducing the potential for contamination of
reclaimed powder.>>> 6 <<<
Required: Acetone or 97%+ isopropyl alcohol, mild dish washing detergent,
clean water, 5 gallon buckets, pre-washed 100% cotton rags, clean hand
sponges and sponge mop.
NOTE: Rags used for cleaning must be washed before use to remove
sizing and starches which would be transferred to the canopy surfaces,
degrading the ability of the canopy to shed powder.
IMPORTANT! If conditioning the canopy after powder has been sprayed in
it, remove all powder residue with damp/wet cotton cloths BEFORE
performing step1 (solvent wipe down) of this procedure.
1. Wipe down entire canopy with acetone or isopropyl alcohol and
pre-washed, 100% cotton rags.
2. Fill two clean buckets with water.
3. Put 2−3 drops of mild dish washing detergent into one of the buckets.
This is the soap bucket.
4. Soak and wring out a hand sponge or a sponge mop in the soap bucket.
Wipe down the entire inside of the canopy, frequently wringing out the
sponge in the rinse bucket and then re-soaping the sponge in the soap
bucket. A continuous wet surface is not necessary, so do not be
concerned if some surfaces air-dry prior to next step. You must make
sure that the soap solution contacts all surfaces.
5. Empty the buckets, rinse them, and repeat steps 1−3, for a total of two
wash cycles.
6. Empty the buckets and rinse them. Fill the buckets with clean water and
rinse the entire inside of the canopy, frequently wringing out the sponge
in the rinse buckets.
7. Repeat step 5 two more times, for a total of three rinse cycles, then
allow the canopy to completely dry before resuming spray operations.
