MAINTENANCE
PROCEDURES To ensure safe, dependable operation of the equipment, follow the
maintenance schedule detailed below:
DAILY
Cleaning & Filling:
• Agitate colorants every morning for five (5) to ten (10) minites.
• Clean nozzles & outside cabinet surfaces with soap and water.
• Check canisters and fill as required.
WEEKLY
Cleaning & Nozzle Maintenance:
• Dispense a full measure of any colorant that has not been used
during the previous week. Dispense into a clean container and
return to the appropriate canister.
• Clean all accessible inside surfaces with soap and water.
GENERAL MAINTENANCE
If a nozzle becomes clogged, the obstruction can generally be cleared by
inserting a paper clip or similar object in the valve opening. Before inserting
such a device, open the valve by pulling the valve lever down and holding
while clearing the opening. BE SURE THAT THE VALVE IS OPENED,
AND STAYS OPEN WHILE CLEANING IN THIS WAY. IF THE
VALVE CLOSES AT ANY TIME DURING THIS OPERATION, THE
VALVE COULD BE DAMAGED. If colorant leaks develop at the top of
the pump, or if colorant can be observed on the pump piston rod, the pump
assembly must be repaired. The Pump Repair Kit (P/N 4223212) can be
purchased from the Fluid Management Customer Service Department. A
colorant leak at the bottom of the pump assembly generally indicates that the
pump assembly has been damaged. In this case, the valve assembly must be
replaced with either the Viton Valve Repair Kit (P/N 4231002) or the
Thiokol Repair Kit (P/N 4231011).
