Flushing; Install The Metered Dispense Valve - Graco SDP8 Series Installation And Operation Manual

Flushing

The equipment was tested with lightweight
oil, which was left in the fluid passages to
protect parts. To avoid contaminating the
fluid, flush the equipment with a compatible
solvent before use.
1. Close the fluid shut-off valve (B, F
page 9) at each dispense position.
2. Make sure:
•
the main fluid outlet valve at the
pump is closed.
•
the air pressure to the pump motor
is adjusted to minimize the system
flow rate without the metered
dispense valve attached.
•
the air valve is open.
3. Slowly open the main fluid outlet valve.
a. Place the hose end (with no
metered dispense valve connected)
into a container for waste oil.
b. Secure the hose in the container to
avoid it becoming loose during
flushing.
c. For multiple dispense positions, first
flush the dispense position farthest
from the pump then work toward the
pump.
4. Slowly open the fluid shut-off valve (B) at
the dispense position. Flush a sufficient
amount of oil to ensure that the entire
system is clean; then close the valve.
5. Repeat Step 4 at all other positions.
