Graco 3A0410D Fluid Supply Line, Fluid Outlet Line, Fluid Inlet and Outlet Ports, Air Line

Installation

Solvent containers used when flushing: Follow local code. Use only conductive metal containers, placed on a grounded surface. Do not place the container on a non- conductive surface, such as paper or cardboard, which interrupts grounding continuity.

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 main- tained.

Polypropylene (3300P)

The fluid inlet and outlet manifolds each have a 3 in. raised face ANSI/DIN center flange.

NOTICE

Use even and opposite torque to connect to the polypropylene manifold flange. Excessive uneven force can damage the flange.

Fluid Supply Line

1.Use grounded, flexible fluid hoses (E). See Ground the System, page 9.

2.If the inlet fluid pressure to the pump is more than 25% of the outlet working pressure, the ball check valves will not close fast enough, resulting in ineffi- cient pump operation. Excessive inlet fluid pressure also will shorten diaphragm life. Approximately 3-5 psi (0.02-0.03 MPa, 0.21-0.34 bar) should be ade- quate for most materials.

3.For maximum suction lift (wet and dry), see Techni- cal Data, page 20. For best results, always install the pump as close as possible to the material source. Minimize suction requirements to maximize pump performance.

Fluid Outlet Line

1.Use grounded, flexible fluid hoses (H). See Ground the System, page 9.

2.Install a fluid drain valve (F) near the fluid outlet.

3.Install a shutoff valve (G) in the fluid outlet line.

Fluid Inlet and Outlet Ports

NOTE: Remove and rotate the center manifold(s) to change the orientation of inlet or outlet port(s). Follow Torque Instructions on page 14.

Aluminum (3300A)

The fluid inlet and outlet manifolds each have a 3 in. ANSI/DIN center flange with either 3 in.-8 npt or

3 in.-11 bspt internal threads.

Stainless Steel (3300S)

The fluid inlet and outlet manifolds each have either 3 in.-8 npt or 3 in.-11 bspt ports.

Air Line

1.Install an air regulator and gauge (C) 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.

Trapped air can cause the pump to cycle unexpect- edly, which could result in serious injury from splash- ing.

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

4.An air line filter (C) removes harmful dirt and mois- ture from the compressed air supply.

5.Install a grounded, flexible air hose (A) between the accessories and the 3/4 npt(f) pump air inlet.
