4. CLEANING THE CANISTER PUMP ASSEMBLY
When it becomes necessary to clean a canister pump assembly, remove the
canister from the base and pour out as much of the colorant as possible.
If the colorants are water soluble, wash the canister thoroughly with warm water
and a liquid detergent and rinse with clean warm water. Next fill the canister with a
small amount of water and with the valve lever closed, raise and lower the knob on
the pump and gauge assembly several times. Then make several dispenses of the
water through the dispense nozzle, the same as you would for colorant. Pour out
any remaining water and wipe dry before replacing the canister on the
dispenser. Dispense any water left in the pump assembly before refilling the
colorant.
If the colorants are not water soluble, the procedure is the same as above, except
in place of water mineral spirits or a similar solvent is recommended.
IMPORTANT:
DO NOT use solvents in canisters intended for water or glycol based colorants as
this will damage the 0-Rings on the Valve Assembly. When cleaning the canister,
DO NOT submerge the pump gauge assembly portion of the canister or let water
or mineral spirits get into the top of the pump assembly.
