SECTION 3.2 – FLUSH PUMP BEFORE INSTALLATION
SECTION 3.3 – START AND ADJUST PUMP
Numbers in parentheses ( ) refer to drawing on page 7.
1. Place the suction hose (16) in the fluid to be pumped.
2. Close the fluid drain valve (14).
3. With the regulator (5) closed, open both bleed-type air
valves (3) & (8).
4. Open the fluid control device while continuing with
the following steps.
5. Slowly open the air regulator (5). Adjust it about 5 PSI
(0.3 Bar) at a time until the pump runs smoothly.
6. Cycle pump slowly until all air is purged out of the
lines (fluid flowing in a steady stream from the fluid
outlet) until the pump is primed.
7. If you are purging:
a. Slowly cycle pump enough to thoroughly clean both
the pump and hoses.
b. Close the gun or fluid control dispensing device and
air regulator (5).
c. Back off air regulator until the gauge reads zero.
d. Remove the suction hose (16) from the solvent and
place it in the fluid to be pumped.
8. Placing the pump in service
a. Start the pump. Be sure the suction hose is in the
supply container and the tube end is below the fluid
level.
b. Read all pressure warnings in this manual and follow
the pressure Relief Procedure on page 5. Trigger the
gun into a grounded metal waste container to prime
the hose. Be sure that the correct spray tip is
installed in the gun. Adjust the pump pressure just
enough to completely atomize the fluid. Higher pres-
sures are unnecessary and only cause premature noz-
zle and pump wear.
c. A pump in a dead end system will cycle upon
demand only.
d. A pump in a circulating system runs continuously
and speeds up or slows down as supply demands.
9. Removing the pump from service.
a. Flush the pump thoroughly before shutting down,
especially if pumping a material that will react with
time or heat.
b. Remove the siphon hose from the supply container
and cycle the pump to force fluid out of the system.
Prime the pump with a compatible solvent and shut
off the air supply.
c. Follow the Pressure Relief Procedure Warning on
page 5.
The pump was factory tested with lightweight oil. Some
residue is left in to protect the pump parts. If this could
contaminate the fluid you are pumping, flush it thoroughly
with a compatible solvent. To start the pump, follow the
procedure in the following section,
Start and Adjust
Pump
.
WARNING
To reduce the risk of fluid injection injury, static sparking,
and splashing, read and follow safety instructions on pages
3 through 5 of this part sheet.
!
WARNING
NEVER allow the pump to run dry of fluid. A dry pump can
accelerate to a high cycle speed, possibly damaging itself.
If the pump accelerates quickly, or is running too fast, stop
it immediately. If the pump is empty and air has been
pumped into the lines, refill the container and again prime
the pump and lines. A pump protector valve is available.
!
NOTE
Check all fittings. Be sure they are tight. Be sure to use
PTFE tape, which is compatible with all fluids, on all male
pipe threads.
