Preparing to Pump Fluid
Follow the steps below to prepare the system for
pumping fluid. Refer to the Typical Installation Draw-
ing, (Fig. 1 on page 7) for more information.
1. Move the hand valve lever to the OFF position
(Fig. 5). Close the ram air regulator and main air
control valve.
2. Move the hand valve lever to the UP position
(Fig. 5). Open the main air control valve and ram
air regulator until the ram starts to move upward.
Let the ram rise to its full height.
3. Set a full pail of fluid on the ram base and center it
under the follower plate.
NOTE: Do not use pails that have side bungs or large
dents with this ram. Rough bung openings or large
dents will damage the wiper or stop the follower plate,
resulting in a runaway pump.
4. Move the hand valve lever to the DOWN position
(Fig. 5) and lower the ram until the follower plate is
just ready to enter the pail, then move the hand
valve lever to OFF. If necessary, reposition the pail
so the wiper will not hit the pail lip.
5. Unscrew the follower plate's bleed handle (see Fig.
1, item (8) on page 7).
6. Move the hand valve lever to the DOWN position
(Fig. 5), to lower the follower plate into the pail,
until all air is forced out and fluid comes out of the
vent opening.
7. Move the hand valve lever to OFF and screw in
the bleed handle (see Fig. 1, item (8) on page 7).
8. Set the air pressure to the ram at 4 bar (50 psi).
Move the hand valve lever to the DOWN position
(Fig. 5).
9. Slowly start the pump by opening both the bleed-
type master air valve and the fluid dispensing
valve. Do not allow the pump to cycle too quickly.
Let the pump run until the system is primed and all
air is forced out.
Operation
10. Stop the pump by closing either the bleed-type
master air valve or the fluid dispensing valve.
NOTE: Increase air pressure to the ram if the pump
does not prime properly with heavier fluids. If fluid is
forced out around the top wiper, ram pressure is too
high and the air pressure should be decreased.
Pumping Fluid
To pump fluid from the pail:
1. Move the hand valve lever to the DOWN position
(Fig. 5).
2. Open the bleed-type master air valve.
3. Start the pump by opening the pump air regulator.
Then adjust the pump for normal operation.
Always use the lowest possible air pressure to both the
pump and ram.
Do not overpressurize the system, as this could
result in serious injury or damage to the equipment.
NOTE: It is normal for the pump to stall if the dispense
gun or other fluid valve is closed.
Changing Pails
To change pails:
1. Stop the pump by closing either the bleed-type
master air valve or the fluid dispensing valve, and
then moving the hand valve lever to UP (Fig. 5).
2. Push the follower blowoff button [see Fig. 1, item
(G) on page 7] in and hold until the follower plate
clears the top of the pail.
3. When the ram reaches its maximum height, move
the hand valve to OFF (Fig. 5).
4. Remove the empty pail and put a full pail in its
place.
5. Perform the procedure, Preparing to Pump
Fluid, above.
