Maintenance
Clean the Dispensing Valve Daily
CAUTION
Be sure the solvent you use is compatible with the
fluid being dispensed, to avoid clogging the valve’s
fluid passages.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 8.
An important part of the care and maintenance of your
automatic dispensing valve is proper flushing. Flush
the valve daily with a compatible solvent until all traces
of fluid are removed from the valve passages.
Relieve
the pressure before flushing.
Clean the outside surfaces of the valve by wiping with
a soft cloth dampened with a compatible solvent.
CAUTION
Never immerse the entire dispensing valve in sol-
vent. Immersing in solvent removes lubricants and
tends to damage packings.
To remove a hardened particle from the orifice, blow
air through the orifice from the front.
Flushing
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 8.
Before flushing, be sure the entire system and flushing
pails are properly grounded. Refer to
Grounding on
page 5. Relieve the pressure and remove the nozzle
from the dispensing valve. Always use the lowest
possible fluid pressure, and maintain firm metal-to-
metal contact between the dispensing valve and the
pail during flushing to reduce the risk of fluid injection
injury, static sparking, and splashing.
Start the pump and flush the system with a compatible
solvent as explained in the instructions for your pump.
Check the system under pressure for leaks; if any are
found,
relieve the pressure and repair the leaks.
Pressurize the system again and make sure the leak-
ing has stopped.
