Installation

General Information

•FIG. 3 on page 8 is only a guide for installing system components and accessories. It is not an actual system design. Contact your Graco distributor for assistance in designing a system to suit your particular needs.

• Always use Genuine Graco Parts and Accessories, available from your Graco distributor. If you supply your own accessories, be sure they are adequately sized and pressure-rated for your system.

• Reference numbers and letters in parentheses refer to the reference numbers in the figures and the parts list on page 23.

Tighten Threaded Connections

Installation

1. Before each use, check all hoses for wear or damage and replace as necessary.

2. Check to be sure all threaded connections are tight and leak-free.

3. Check and re-torque all screws and fasteners at least every two months. Re-torque the fluid cover screws first, followed by the manifold screws. Note: Before using pump, loosen fluid cover screws (31) 1-2 turns and then re-torque to 20 N•m (15 ft-lb).

Installation

Mounting the Pump

For ease of operation and service, mount the pump so the air inlet, fluid inlet, and fluid outlet ports are easily accessible. The inlet port must point down and the outlet port must point up.

Use 5/8 in. lag screws or bolts for mounting.

To ensure proper operation, mount the pump in a horizontal position.

Wall Mount Installation

1. Wall Mount Kit 245875 is available. See FIG.1.

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

3. Using the wall bracket (B) as a template, drill 5/8 in. mounting holes in the wall. See page 27 for a wall mounting diagram. Mount the bracket 1.2-1.5 m (4-5 ft) above the floor.

Floor Stand Installation

Floor Stand Kit 245874 is available. See FIG.2to assemble.

4. Attach the bracket (B) to the pump (A) with the screws (C) and washers (D) provided in the kit.

5. Attach the bracket to the wall. Use screws (E) that are long enough to keep the pump from vibrating during operation. Be sure the pump is level.

Installation

Air Line

1. Install the air line accessories as shown in FIG.3. Mount these accessories on the wall or on a bracket. Be sure the air line supplying the accessories is grounded.

a. Install an air regulator (C) and gauge to control

the fluid pressure. The fluid outlet pressure will be three times the setting of the air regulator.

b. A bleed-type master air valve (B) is required in

your system to relieve air trapped between it and the pump when the valve is closed. Trapped air can cause the pump to cycle unexpectedly which could result in serious injury including splashing in the eyes or on the skin, or injury from moving parts. Be sure the bleed valve is easily accessible from the pump, and is located downstream from the air regulator.

c. The air line filter (D) removes harmful dirt and

moisture from the compressed air supply.

Fluid Outlet Line

1. Use conductive fluid hoses (J). See FIG.3.See Technical Data on page 25 to determine the fluid outlet size of your pump.

2. Install a fluid drain valve (G) near the fluid outlet. The fluid drain valve is required to relieve pressure in the hose and gun. The drain valve reduces the risk of serious injury, including splashing in the eyes or on the skin, or injury from toxic fluids.

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

d. A second bleed-type air valve (T) isolates the air

line accessories for servicing. Locate upstream from all other air line accessories.

2. Install a grounded, flexible air hose (A) between the accessories and the pump air inlet. See Technical Data on page 25 to determine the air inlet size of your pump. Use a minimum 13 mm (1/2 in.) ID air hose.

3. Screw an air line quick disconnect coupler (N) onto the end of the air hose (A), and screw the mating fitting into the pump air inlet snugly. Do not connect the coupler to the fitting until you are ready to operate the pump.

Fluid Suction Line

• Use conductive hoses (E). See FIG.3.

• See Technical Data on page 25 to determine the fluid inlet size of your pump.

• For maximum suction lift (wet and dry) information, see Technical Data on page 25.
