Filter Maintenance
There are two filters on the sprayer. One is a canister
type that filters the water entering the tank and the other
is a Whirlfilter® that filters the chemical solution being
sprayed.
These need to be cleaned seasonally, or sooner if flow
restriction is observed.
Clean-out the solution Whirlfilter®
Fill the sprayer tank with water and turn the pump on.
2.
With the pump running, slowly open the clean-out
valve and allow the grit to flow out into a bucket.
Clean out the solution Whirlfilter® only when the
sprayer tank is filled with water and no chemical has
been added.
3.
Close the clean-out valve and turn off the pump.
4.
Dispose of the grit and water in the same manner
described on the manufacturer’s label of the latest
chemical used in the sprayer.
Clean Out Tank Fill Filter
Wear chemical gloves and protective clothing. Although used
for adding clean water, the chemical mix in the main tank can
back-wash into this assembly.
Start with an empty sprayer tank.
2.
Position a bucket under the plug
in the sump cap
of the filter. Remove the plug and allow the grit to
fall out.
3.
Screw the plug back in using pipe thread sealant to
seal the plug.
4.
Dispose of the grit and water in the same manner
described on the manufacturer’s label of the latest
chemical used in the sprayer.
If draining the filter does not improve flow:
5.
Unscrew the entire sump cap
. Remove it slowly
and save the gasket
.
6.
Remove the filter element
. Clean or replace it.
7.
Re-assemble the filter. No thread sealant is required
on the main cap threads.
