• Clothing and respirator as recommended by the fluid and solvent manufacturer

• Protective eyewear, gloves, and hearing protection

Installation

The Typical Installations shown in FIG. 3 and F

IG. 4 are only guides for selecting and install-

ing system components. Contact your Graco distributor for assistance in planning a system to suit your needs.

Tighten Fasteners Before Setup

Before using the pump for the first time, check and retorque all external fasteners. Follow Torque Instructions, page 16.

Installation

Mounting

• The pump exhaust air may contain contam-

inants. Ventilate to a remote area. See Air Exhaust Ventilation on page 8.

• Never move or lift a pump under pressure.

If dropped, the fluid section may rupture. Always follow the Pressure Relief Proce- dure on page 14 before moving or lifting the pump.

1. Be sure the mounting surface can support the weight of the pump, hoses, and accessories, as well as the stress caused during operation.

2. For all mountings, be sure the pump is bolted directly to the mounting surface.

wire to a true earth ground. A ground wire and clamp, Part 238909, is available from Graco.

Polypropylene: Only conductive polypropylene pumps have a ground screw. Standard polypropylene pumps are not conductive. Never use a non-conductive polypropylene pump with non-conductive flammable fluids. Follow your local fire codes. When pumping conductive flammable fluids, always ground the entire fluid system as described.

3. For ease of operation and service, mount the pump so air valve, air inlet, fluid inlet and fluid outlet ports are easily accessible.

4. Rubber Foot Mounting Kit 236452 is available to reduce noise and vibration during operation.

Grounding

The equipment must be grounded. Grounding reduces the risk of static and electric shock by providing an escape wire for the electrical current due to static build up or in the event of a short circuit.

Pump: See FIG. 1. Loosen the grounding screw (GS). Insert one end of a 12 ga. minimum ground wire (R) behind the grounding screw and tighten the screw securely. Connect the clamp end of the ground

ti12214a

FIG. 1. Grounding screw and wire

Air and fluid hoses: Use only grounded

hoses with a maximum of 500 ft (150 m) combined hose length to ensure grounding continuity.

Air compressor: Follow manufacturer’s recommendations.

Fluid supply container: 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.

312877C 7

Installation

Check your system electrical continuity after the initial installation, and then set up a regular schedule for checking continuity to be sure proper grounding is maintained.

Air Line

See FIG. 3 and FIG. 4, pages 10 and 11.

1. Install an air regulator (C) and gauge to control the fluid pressure. The fluid stall pressure will be the same as the setting of the air regulator.

2. Locate a bleed-type master air valve (B) close to the pump and use it to relieve trapped air. Be sure the valve is easily accessible from the pump and located downstream from the regulator.

Remote option: Insert 5/32 OD tubing into the push-to-connect fitting at each pilot and route to your control.

NOTICE

Pilot supply pressure should not exceed main air supply pressure. If pilot supply pressure is too high, the pump could leak air or exhaust excessive air at stall.

Reed Switch

Pulse Count models are intended for use with customer-supplied fluid management or inventory tracking systems. Attach an M12, 5-pin female cable to connect the reed switch to your data monitoring system. See Manual 406824.

Air Exhaust Ventilation

Trapped air can cause the pump to cycle unexpectedly, which could result in serious injury from splashing.

3. Locate another master air valve (E) upstream from all air line accessories and use it to isolate them during cleaning and repair.

4. An air line filter (F) removes harmful dirt and moisture from the compressed air supply.

5. Install a grounded, flexible air hose (A) between the accessories and the 1/2 npt(f) pump air inlet (D). Use a minimum 3/8 in. (10 mm) ID air hose.

The air exhaust port is 3/4 npt(f). Do not restrict the air exhaust port. Excessive exhaust restriction can cause erratic pump operation.

To provide a remote exhaust:

1. Remove the muffler (T) from the pump air exhaust port.

2. Install a grounded air exhaust hose (U) and connect the muffler (T) to the other end of the hose. The minimum size for the air exhaust hose is 3/4 in. (19 mm) ID. If a hose longer than 15 ft (4.57 m) is required, use a larger diameter hose. Avoid sharp bends or kinks in the hose.

3. Place a container at the end of the air exhaust line to catch fluid in case a diaphragm ruptures. If the diaphragm ruptures, the fluid being pumped will exhaust with the air.
