Shutdown
1. If a fluid heater is used, turn it off 10 to 15 minutes before shutting down
the pump. This prevents coating material from curing inside the heater.
2. Shut off the air supply to the pump.
3. Relieve the system hydraulic pressure by triggering the spray device(s)
or carefully opening a drain valve.
NOTE:
Normally, you can leave the system filled with coating material
overnight. If the material contains solids that easily settle out, circulate
material through the system for several minutes before spraying. Do not
leave the system open to air. The coating material could cure and clog the
system. If the system will be shut down for more than a few days, flush it
and leave it filled with clean solvent or waterborne cleaning solution.
Maintenance
WARNING:
Allow only qualified personnel to perform the following tasks.
Follow the safety instructions in this document and all other related
documentation.
WARNING:
Stop the pump and relieve air and hydraulic pressures before
disconnecting air or fluid hoses, or before disassembling any equipment.
Daily
Do the following daily:
1. Make sure that all conductive equipment in the spray area, including the
pump and waste container, are securely connected to a true earth
ground.
2. Drain the air filter. Check the filter element and replace it if necessary.
Open the drop leg drain valve and drain collected moisture.
3. Fill the air lubricator.
4. Clean the fluid filter screen. Replace the screen as necessary.
5. Check the level of solvent fluid in the solvent chamber. Add more
solvent fluid as needed.
NOTE:
Coating material leaking past the upper packing gland will
discolor the solvent fluid and cause its level to rise. A small amount of
leakage is normal. Drain and refill as needed.
The upper and lower packings are self-adjusting. If the solvent chamber
quickly fills then the upper packings are worn or damaged and need to
be replaced. Both upper and lower packings should be replaced at the
same time.
6. Flush the pump and system at each material change.
