Installation
Mounting the Elevator Base to the Floor
You must mount th e elevator base to the floor
before you operate this equipment.
WARNING
1. Positi on 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 elevato r base, using shim s if necessary,
and bolt the base firmly to the fl oor.
Grounding
Proper grounding is an essential part of maintaining a
safe system.
To reduce the risk of static sparking, th e mounting
cover and all electrically conductive objects or devices
in th e dispensing a rea must be properly grounded.
Check your local electrica l code fo r detailed grounding
instru ctions for your area and type of equipment.
To ground the dispenser, connect the end of th e
ground wire to a true earth ground.
Operation
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
agitato r (disconnec t 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.
Startup
See the Parts Drawing on page 4.
1. Flush the dispenser before first use.
NOTE: The pump was tested in water. To elimi-
nate possible contamination of the fluid you are
pumping, before you use the dispenser, flush the
pump thoroughly with a solvent compatible to th e
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
agitato r speed, gradually increase the speed until
you can see (through the inspection port in the
drum cover) movement in the surface of th e liquid,
but do not increase the agitator speed enough to
create a vorte x in the surfac e of the liquid. If the
surface begins to vortex, decrease the agita tor
speed to prevent air entrainment.
NOTE: Always maintain moderate agitator speed,
which is approximately 50 rpm of the agitator
blades. Ex cessive agitator speed may cause
vibration, foaming of fluid, and incr eased wear on
parts . Always agitate fluid thor oughly before
supplying it to the dispens ing equipment, and
continue agitating fluid while the dispens ing equip-
ment 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 push-
ing 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 press ure 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 res tricto r valve,
and tu rn the valve needle out. To decrease the
operating speed, tu rn the valve needle in. The
restrictor valve is on the top of the elevator, as
shown i n the Parts Drawing.
