Installation
The Graco warranty will not apply if cleaning solutions other than those recommended by Graco are used in these units. Only use solutions that are not harmful to the wetted parts. See the Technical Data in the displace- ment pump manuals 311825, 311827, and 312745.
See FIG. 1. Connect the suction hose (P) between the pump fluid inlet and the suction tube (R), using thread sealant on the male threads. Screw on the suction tube strainer. Place the suction tube in the supply drum, and adjust it so it is 1 in. (25 mm) off the bottom of the drum. Tighten the thumbscrew of the pipe hanger onto the drum.
Connect the spray hose (S) to the pump outlet manifold. For two gun spraying, remove the plug in the manifold and connect another spray hose. Connect the spray gun
(T)to the hose (S). Use thread sealant on the male threads.
Flush Before Using Equipment
The equipment was tested with lightweight oil, which is left in the fluid passages to protect parts. To avoid con- taminating your fluid with oil, flush the equipment with a compatible solvent before using the equipment. See your respective pump manual. See Related Manuals on page 3.
Integrated Air Control Module
See FIG. 1. The integrated air control module (C) is included with all packages. It includes the following (see
311239 for detailed information):
•
Wall Mount Packages
1.Ensure the wall is strong enough to support the weight of the pump assembly and accessories, fluid, hoses, and stress caused during pump operation.
2.Ensure that the mounting location has sufficient clearance for easy operator access.
3.Position the wall bracket at a convenient height, ensuring that there is sufficient clearance for the fluid suction line and for servicing the displacement pump.
4.Drill four 7/16 in. (11 mm) holes using the bracket as a template. Use any of the three mounting hole groupings in the bracket. See Wall Mounting Bracket Diagram, page 20.
5.Bolt the bracket securely to the wall using bolts and washers designed to hold in the wall’s construction.
6.Attach the pump assembly to the mounting bracket.
7.Connect air and fluid hoses.
Trapped air can cause the pump to cycle unexpectedly, which could result in serious injury from splashing or moving parts.
•Pump air regulator (E): adjusts air pressure to the motor and fluid outlet pressure of pump. View the gauge (F) to read air pressure.
•Safety relief valve (G): automatically opens to relieve air pressure, to prevent pump overpressur- ization.
•Air filter (H): removes harmful contaminants from entering the air control module and air motor.
