•
If this is a new installation or if the fluid
lines are contaminated, flush the lines
before installing the metered dispense
valve. Contaminated lines could cause
the metered dispense valve to leak.
•
Never dispense compressed air with a
metered dispense valve. Dispensing
compressed air damages the metered
dispense valve.
