Installation

Grounding

The equipment must be grounded to reduce the risk of static sparking. Static sparking can cause fumes to ignite or explode. Grounding provides an escape wire for the electrical current.

Pump: Connect a ground wire (Graco PN 238909) to the ground screw on the air motor base. Connect the other end of the ground wire to a true earth ground.

Air and ﬂuid hoses: Use only electrically conductive hoses with a maximum of 500 ft. (150 m) combined hose length to ensure grounding continuity. Check electrical resistance of hoses. If total resistance to ground exceeds 25 megohms, replace hose immediately.

Air compressors: Follow manufacturer’s recommendations.

Dispense valve: Ground through connection to a properly grounded ﬂuid hose and pump.

Material supply container: Follow local code.

Container(s) that receive material: Follow local code.

during operation. Do not use air or ﬂuid lines to support the pump.

Setup

To avoid contaminating the ﬂuid, pipe the exhaust air to vent outside of the ﬂuid product area, away from people, animals, or food handling areas.

Note

Reference numbers and letters in parentheses in the text refer to the callouts in the ﬁgures and the parts drawings.

Accessories are available from Graco. Make certain all accessories are sized and pressure rated to meet your system requirements.

Figure 1 is only a guide for selecting and installing system components and accessories. Contact your Graco distributor for assistance in designing a system to suit your particular needs.

Install a ﬂuid drain valve (P) close to the ﬂuid outlet to relieve ﬂuid pressure in the hose.

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

Mounting

Mount the pump to fully support the weight of the pump and accessories, as well as the stress caused

Install a pump runaway valve (L) in the pump air line to shut off air to the air motor automatically if the pump starts to run too fast.

Install another bleed-type master air valve (G) upstream from all air line accessories and use it to isolate the accessories during cleaning and repair.

Operation

NOTICE

Do not expose the air motor to temperatures higher than 120°F (49°C) or the immersed ﬂuid pump to temperatures higher than 250°F (121°C). Excessive temperatures may damage the pump packings and seals.

To avoid injury from exhaust hose whip, never operate the pump without a mufﬂer installed. Secure the exhaust hose to a solid, stationary object.

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

1. Shut off the air supply to the pump.

2. Close the bleed-type master air valve (required in system).

3. Open the ﬂuid ball valve and/or dispensing valve to relieve ﬂuid pressure.

4. Open all ﬂuid drain valves in the system, having a waste container ready to catch drainage. Leave drain valve(s) open until you are ready to dispense again.

NOTIC

Never allow the pump to run dry of ﬂuid. A dry pump will accelerate to a high speed, possibly damaging itself.

If the pump accelerates quickly, or is running too fast, stop the pump immediately and check the ﬂuid supply. If the supply is empty and air has been pumped into the lines, replace the container and prime the pump and lines with ﬂuid. Be sure to eliminate all air from the system.
