Installation

Mounting the Elevator Base to the Floor

WARNING

You must mount the elevator base to the floor before you operate this equipment.

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

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.

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 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, foaming of fluid, and increased wear on parts. Always agitate fluid thoroughly before supplying it to the dispensing equipment, and continue agitating fluid while the dispensing 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 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.
