WARNING

A red-handled bleed-type master air valve (F) and a fluid drain valve (D) are supplied. These accesso- ries help reduce the risk of serious injury, including fluid injection and splashing of fluid in the eyes or on the skin, and injury from moving parts if you are adjusting or repairing the pump.

The bleed-type master air valve relieves air trapped between this valve and the pump after the air is shut off. Trapped air can cause the pump to cycle unexpectedly. Locate the valve close to the pump.

The fluid drain valve assists in relieving fluid pres- sure in the displacement pump, hose, and gun. Triggering the gun to relieve pressure may not be sufficient.

DThe red-handled bleed-type master air valve (F) is required in your system to relieve air trapped between it and the air motor when the valve is closed (see the WARNING above). Be sure the bleed valve is easily accessible from the pump, and is located downstream from the air filter/regulator

(H).

DThe air filter/regulator (H) controls pump speed and outlet pressure by adjusting the air pressure to the pump. It also removes harmful dirt and moisture from the compressed air supply. Locate close to the pump, but upstream from the bleed-type master air valve (F).

DThe air manifold (J) provides ports for connecting lines to air-powered accessories.

DThe air relief valve (38) opens automatically to prevent overpressurization of the pump.

DThe fluid filter (4) or surge tank includes a 60 mesh (250 micron) stainless steel element to filter particles from the fluid as it leaves the pump. It includes the fluid drain valve (D), which is re- quired in your system to relieve fluid pressure in the hose and gun (see the WARNING at left).

DThe suction hose (8) and tube (7) allow the pump to draw fluid from a 5 gallon (19 liter) pail.

Connect the Fluid Hoses and Gun

NOTE: Models 237–296 and 238–906 include fluid hoses, a spray gun, and connecting parts (ref. nos. 102–106). If you supply your own fluid hoses and gun, be sure they are properly sized and pressure-rated for your system. Use only electrically conductive hoses.

1.Connect the main fluid hose (103) to the fluid filter

(4)outlet.

2.Screw the coupling (105) onto the other end of the main fluid hose (103).

3.Screw the short whip hose (104) onto the coupling

4.Screw the whip hose (104) onto the gun swivel

5.Screw the gun swivel (106) onto the fluid inlet of the spray gun (102).
