WARNING

FIRE AND EXPLOSION HAZARD

Improper grounding, poor ventilation, open flames, or sparks can cause a hazardous condition and result in a fire or explosion and serious injury.

D Ground all equipment. Refer to Grounding on page 5.

D If there is any static sparking or you feel an electric shock while using this equipment, shut off the

agitator immediately. Do not use the equipment until you identify and correct the problem.

D Do not use 1,1,1–trichloroethane, methylene chloride, other halogenated hydrocarbon solvents, or

fluids containing such solvents in aluminum pumps. Such use could result in a serious chemical reaction, with the possibility of explosion.

D Do not use kerosene or other flammable solvents or combustible gases to flush the unit.

D Provide fresh air ventilation to avoid the buildup of flammable fumes from solvents or the fluid

being dispensed.

D Keep the dispensing area free of debris, including solvent, rags, and gasoline.

D Do not smoke in the dispensing area.

D Keep a fire extinguisher in the work area.

MOVING PARTS HAZARD

Moving parts, such as the rotating blades of the agitator, can pinch or amputate your fingers or other body parts and can cause splashing in the eyes or on the skin.

D Keep clear of all moving parts when starting or operating the agitator.

D Always shut off the agitator and disconnect the air line before you remove the agitator from the

drum or check or repair any part of the agitator.

HAZARDOUS VAPORS

Hazardous fluids or toxic fumes can cause serious injury or death if splashed in the eyes or on the skin, swallowed, or inhaled. When flushing the air motor, keep your face away from the exhaust port.

Installation

WARNING

FIRE AND EXPLOSION HAZARD

Always maintain a minimum of 1 in. clearance between rotating agitator parts

and container to prevent sparks from contact.

Installing the Agitator

1. Install the agitator on the container cover by screwing the helix through the drum bung hole and screwing the agitator housing into the bung hole. Refer to the Dimension Drawing on page 11.

Air Requirements

For continuous use, the 1/2 HP agitator air motor typically requires 2 scfm (0.06 m#/min.) of air at 400 rpm and with 100 psi (7 bar) inlet pressure.

Air Line Accessories

Install an air line filter to remove harmful dirt and moisture from the air supply. Order Part No. 106148 for 3/8 npt or 106146 for 1/2 npt.

Keep the agitator tightly mounted to the drum bung to prevent damage to the threads from vibration.

When using a modified drum check that there is no interference between the base of the drum and the shaft of the agitator.

2. Position the air motor so the air line can easily be attached to the needle valve’s 1/8 npt inlet, without obstructing any other system components. See Fig. 1.

3. Attach an air line quick disconnect valve or ball valve for main air shutoff. Order Part No. 208536, Coupler and 169969 Fitting, Quick Disconnect Air Line Fitting.

4. Attach the air line between the needle valve’s 1/8 npt inlet and the 1/8 npt air supply manifold outlet.

CAUTION

Not lubricating the air motor will cause air motor failure.

Downstream from the filter, install an air line lubricator for automatic air motor lubrication. Set the lubricator feed rate at 1 drop of oil per minute for high speed or continuous duty usage. Do not overfeed oil or exhaust air may become contaminated. To manually lubricate the air motor, see Lubricating the Air Motor on page

7. To order a 3/8” npt air line lubricator, order Part No.

Installation

Grounding

Proper grounding is an essential part of maintaining a safe system.

To reduce the risk of static sparking, all electrically conductive objects or devices in the spray area must be properly grounded. Check your local electrical code for detailed grounding instructions for your area and type of equipment.

To ground the agitator:

Remove the grounding screw (A) and lockwasher (B). See Fig. 2. Secure the ground wire terminal (C) to the agitator with the screw and lockwasher. Connect the other end of the ground wire to a true earth ground. Order Part No. 222011, Ground Wire and Clamp.
