Mount the Pump

Mount the pump only to Graco wall bracket 15T795, or to a Graco cart, available from your distributor. Pump dimensions are shown on page 28. For wall mounted pumps, follow these guidelines:

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

2.Position the wall bracket about 1.2-1.5 m (4-5 ft) above the floor. For ease of operation and service, make sure the pump air inlet, fluid inlet, and fluid outlet ports are easily accessible.

3.Using the wall bracket as a template, drill 10 mm (0.4 in.) mounting holes in the wall. Wall mounting dimensions are shown on page 29.

4.Attach the bracket to the wall. Use 9 mm (3/8 in.) screws that are long enough to keep the pump from vibrating during operation.

NOTE: Be sure the bracket is level.

Air and Fluid Hoses

Be sure all air hoses (N) and fluid hoses (M) are prop- erly sized and pressure rated for your system. See FIG. 3. Use only electrically conductive fluid hoses.

Accessories

Install the following accessories in the order shown in FIG. 3, using adapters as necessary.

Air Line

Bleed-type master air valve (E): required in your system to relieve air trapped between it and the air motor and gun when the valve is closed.

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

Be sure the valve is easily accessible from the pump and located downstream from the air regulator.

Installation

Pump air regulator (H): controls pump speed and outlet pressure. Locate it close to the pump.

Air line filter (B): removes harmful dirt and mois- ture from compressed air supply.

Air shutoff valve (A): isolates air line accessories for servicing. Locate upstream from all other air line accessories.

Gun air regulator (D): controls air pressure to the air-assisted spray gun.

Fluid Line

Fluid filter (P): with a 60 mesh (250 micron) stain- less steel element to filter particles from the fluid as it leaves the pump.

Fluid drain valve (W): required in your system, to relieve fluid pressure in the hose and gun.

Gun or valve (L): dispenses the fluid. The gun shown in FIG. 3 is an air-assisted spray gun for light to medium viscosity fluids.

Fluid line swivel (K): for easier gun movement.

Suction kit (V): enables the pump to draw fluid from a container.
