Installation

Grounding

The equipment must be grounded to reduce the risk of static sparking and electric shock. Electric or static sparking can cause fumes to ignite or explode. Improper grounding can cause electric shock. Grounding provides an escape wire for the electric current.

Pump: Use a ground wire and clamp as shown in FIG. 1.

FIG. 1

To ground the pump: Remove the ground screw (Z) and insert through the eye of the ring terminal at end of ground wire (Y). Fasten the ground screw back onto the pump and tighten securely. Connect the other end of the ground wire to a true earth ground. See F a ground and wire clamp, order Part No. 222011.

IG. 1. To order

Mounting the Pump

Mount the pump securely so that it cannot move around during operation. Failure to do so could result in personal injury or equipment damage.

• Select a convenient location for the equipment to ensure easy operator access to the pump air controls, sufficient room to change supply containers, and a secure mounting platform.

• If you are mounting the pump directly on the supply tank, position the pump so its intake valve is no more than 1 inch (25 mm) from the bottom of the container. Mount the pump to the cover or other suitable mounting device.

Air and fluid hoses: Use only electrically conductive hoses.

Air compressor: Follow manufacturer’s recommendations.

Dispense valve: Ground through connection to a prop-

erly grounded fluid hose and pump.

Object being dispensed: follow local code.

Solvent pails used when flushing: Follow local code.

Use only conductive metal pails, placed on a grounded surface. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts grounding continuity.

To maintain grounding continuity when flushing or relieving pressure: hold metal part of the spray

gun/dispense valve firmly to the side of a grounded metal pail, then trigger the gun/valve.

Typical Installation

Mount the pump to suit the type of installation planned. Very heavy lubricant may require an inductor plate. See page 17 for the mounting hole layout and dimensions.

Install the airline accessories in the approximate order shown in F within easy reach of the pump, upstream from the air regulator. Install an air filter (C) to remove harmful dirt and moisture from your compressed air supply. For automatic air motor lubrication, install an air line oiler (D) close to the pump air inlet. Install an air regulator (E) to control pump speed.

IG. 2. Install a bleed-type master air valve (B)

A bleed-type master air valve (B) is required to shut off an relieve air pressure that may be trapped in the air motor. Trapped air could cause the pump to cycle unexpectedly and cause serious bodily injury, including amputation.

Installation

Be sure the air hose is properly sized to deliver an adequate supply of air to the motor. Refer to the Technical Data on page 16.

Connect a dispensing hose to the 3/8 npt(f) pump outlet. Install an appropriate gun or dispense valve to the hose.

Ground the pump as explained on page 4.

Operation

Pressure Relief Procedure

Follow the Pressure Relief Procedure whenever you see this symbol.

This equipment stays pressurized until pressure is manually relieved. To help prevent serious injury from pressurized fluid, such as skin injection, splashing fluid and moving parts, follow the Pressure Relief Procedure when you stop spraying and before cleaning, checking, or servicing the equipment.

1. Close the air regulators (E).

2. Close the supply pump’s bleed-type air master valve (B, required in system).

3. Open the dispensing valve (G) until pressure is fully relieved.

NOTE: If you suspect that the dispensing valve, extension, or grease fitting coupler is clogged, or that pressure has not been fully relieved after following the steps above, VERY SLOWLY loosen the coupler or hose end coupling and relieve pressure gradually, then loosen completely and clear the clog.

Startup and Adjustment

Open the bleed-type air master valve (B). Open the dispensing valve (G), and slowly open the air regulator (E) until the pump is running smoothly. After all the air is purged, close the dispensing valve. The pump will start and stop as the valve is opened and closed.

NOTICE

Never allow the pump to run dry of the fluid being pumped. A dry pump quickly accelerates to a high sped and may damage itself. If your pump accelerates quickly or is running too fast, stop it immediately and check the fluid supply. If the supply container is empty and air has been pumped into the lines, prime the pump and the lines with fluid, or flush the pump and leave it filled with a compatible solvent. be sure to eliminate all air from the fluid system.

Use the air regulator (E) to control the pump speed and fluid pressure. See F sure necessary to obtain the desired results.

When you are finished using the pump for the day always follow the Pressure Relief Procedure.

IG. 2. Always use the lowest pres-

Maintenance

The accessory air line oiler (D) provides automatic air motor lubrication. Four daily manual lubrication, disconnect the air hose, place about 15 drops of light machine oil in the air inlet, reconnect the hose, and turn on the air supply to blow oil into the motor.
