Operation
WARNING
To reduce the risk of serious injury, always discon-
nect air and relieve pressure in lines before at-
tempting any service.
1.
Open the vent inductor plate (8) by turning the
knob (37) counterclockwise. See Fig. 2.
Note: For steps 2–8, see the parts drawing on
page 6.
2.
With the air supply turned on, connect the airline
coupler (4) to the fitting on top of the elevator
tube. Elevator speed may be regulated by turning
the adjusting screw clockwise to decrease, and
counterclockwise to increase elevator speed.
3.
Center an opened drum of material under the
inductor plate (8) so that the drum bottom touches
the elevator base casting. The top surface of the
material should be made concave by scooping
material from the center to the sides of the con-
tainer.
4.
Disconnect the air line coupler (4) and guide the
inductor plate (8) into the drum. Press down on the
pump and rock or jiggle it back and forth to seat
the inductor plate and get rid of any trapped air,
and continue action until material appears at the
vent opening. Slide the plastic cover (9) down onto
the drum.
5.
Close the inductor plate vent, and open the bleed-
er valve by turning the thumbscrew (25*) counter-
clockwise.
6.
Start the pump by connecting the air line
coupler (4) to the pump inlet fitting.
7.
Let the pump run until material appears at the
bleeder valve.
8.
Disconnect the air line coupler (4) and close the
bleeder valve. The unit is now ready for operation.
Note: When supplied with sufficient air pressure, the
pump is remotely controlled at the dispensing valve.
The pump starts and stops as the dispensing valve is
opened or closed.
Note: For overnight or holiday shutdown, disconnect
the air line coupler (4) and relieve the pressure in the
lines.
Changing the Drums
1.
Disconnect the air line coupler (4) from the
pump.
2.
Open the inductor plate vent, and connect the
coupler to the elevator to raise the unit.
Note: If the empty drum rises with the unit, pull the
front of the drum down and forward to break it loose
from the inductor plate.
3.
Remove the empty drum from the base, and install
a full drum as explained at left.
Removing the Pump for Service
Unscrew the locking nut (40) (taking note of the
number of turns). Disconnect hoses and pump from
the mounting and remove.
When attaching the pump, turn the locking
nut (40) the same number of turns as when disassem-
bling, or a slight distance further. Check for 1/8”
(3 mm) clearance. See Fig. 3.
Note: For pump and elevator operation,
troubleshooting, and service instructions, see the
separate manuals.
