Installation
Mounting the Elevator Base to the Floor
1. Position the elevator where there is at least 9 feet
(2.75 meters) of overhead clearance.
2. Mark and drill holes in the floor for 0.5-in. (13 mm)
mounting bolts. See the mounting layout in the
Dimensional Drawing on page 7.
3. Level the elevator base, using shims if necessary,
and bolt the base firmly to the floor.
Grounding
Proper grounding is an essential part of maintaining a
safe system.
To reduce the risk of static sparking, the mounting cover
and all electrically conductive objects or devices in the
dispensing area must be properly grounded. Check your
local electrical code for detailed grounding instructions for
your area and type of equipment.
To ground the dispenser, connect the end of the
ground wire to a true earth ground.
Operation
Startup
See the Parts Drawing on page 4.
1. Flush the dispenser before first use.
NOTE: The pump was tested in water. To eliminate
possible contamination of the fluid you are pumping,
before you use the dispenser, flush the pump
thoroughly with a solvent compatible to the solvent
you are dispensing.
2. Ensure that the needle valve on the agitator is closed
and that the dispenser ball valve (19) is closed.
3. Connect the air supply line to the male air line
fitting (22).
4. Using the needle valve on the agitator to adjust the
agitator speed, gradually increase the speed until
you can see (through the inspection port in the drum
cover) movement in the surface of the liquid, but do
not increase the agitator speed enough to create a
vortex in the surface of the liquid. If the surface
begins to vortex, decrease the agitator speed to
prevent air entrainment.
NOTE: Always maintain moderate agitator speed,
which is approximately 50 rpm of the agitator blades.
Excessive agitator speed may cause vibration, foam-
ing of fluid, and increased wear on parts. Always agi-
tate fluid thoroughly before supplying it to the
dispensing equipment, and continue agitating fluid
while the dispensing equipment is being supplied.
5. Use the regulator (10) and ball valve (19) to control
the pressure and operation of the pump (1).
6. Raise or lower the elevator by pulling out or pushing
in the air control valve (a push-pull handle) on the rim
of the drum cover. Normal operation requires only a
few seconds for air pressure to build up and raise the
elevator or to exhaust and lower the elevator.
NOTE: To increase the operating speed of the
elevator, loosen the hex nut on the restrictor valve,
and turn the valve needle out. To decrease the
operating speed, turn the valve needle in. The
restrictor valve is on the top of the elevator, as shown
in the Parts Drawing.
WARNING
You must mount the elevator base to the floor before
you operate this equipment.
WARNING
MOVING PARTS HAZARD
To reduce the risk of serious injury,
including cuts, amputation of fingers by the
agitator blades, and splashing in the eyes
or on the skin, always shut off the agitator (disconnect
the air line from the agitator) before you raise, check,
or repair the agitator.
Never operate the agitator when the elevator is
raised. See MOVING PARTS HAZARD on page 3.
