Adjusting the Regulator
The fluid pressure regulator controls pressure down
stream from its outlet.
NOTE:
The inbound fluid pressure needs to be higher
than the set point fluid pressure.
To adjust the fluid regulator, first, back the knob out until
there is no spring pressure. Then, turn the knob clock-
wise to increase the pressure.
NOTE:
If you are using an accessory fluid pressure
gauge, relieve the spray gun line when reducing pres-
sure to ensure a correct gauge reading.
Adjust the pump air pressure and the fluid regulator for
the best spraying combination. In a circulating system,
also adjust the back pressure valve.
Record all the settings for future reference. The valve
cylinder (7) has exterior markings (set points 1 to 8) for
repeat settings.
Flush the Equipment
•
Flush before changing colors, before fluid can dry in
the equipment, at the end of the day, before storing,
and before repairing equipment.
•
Flush at the lowest pressure possible. Check con-
nectors for leaks and tighten as necessary.
•
Flush with a fluid that is compatible with the fluid
being dispensed and the equipment wetted parts.
1.
Record the pressure adjustment setting of the regu-
lator before flushing.
2.
Shut off the pump and follow
.
3.
Never exceed the maximum working pressure of the
lowest rated system component.
4.
Open the fluid regulator by turning the adjusting
knob (6) fully
clockwise
.
5.
Supply solvent to the system. Set pump to the low-
est possible pressure, and start pump.
6.
Flush until thoroughly clean.
7.
Adjust the fluid regulator to return to the desired
fluid pressure setting.
To avoid fire and explosion, always ground equipment
and waste container. To avoid static sparking and
injury from splashing, always flush at the lowest pos-
sible pressure.
