Supplied Components

Refer to Fig. 2.

WARNING

A red-handled bleed-type master air valve (50) 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 valve is closed. 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

(50)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 regulator (33).

DWith a wrench, loosen and remove the female air line coupler (69). Screw it onto the main air hose

(A). Leave the mating coupler (68) attached to the air manifold (46)

DThe air regulator (33) controls pump speed and outlet pressure by adjusting the air pressure to the pump. Locate the regulator close to the pump, but upstream from the bleed-type master air valve.

DThe air manifold (46) provides ports for connect- ing lines to air-powered accessories.

DThe air relief valve (70) opens automatically to prevent overpressurization of the pump.

DThe fluid filter (18) 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 required in your system to relieve fluid pressure in the hose and gun (see the WARNING above).

DThe suction hose (12) and tube (13) allow the pump to draw fluid from a fluid container.

DTwo fluid shutoff valves (67) are supplied at the fluid filter outlets. Attach the fluid hose (103) to one of the valves. Keep the other valve capped and closed at all times unless you are using a second hose and gun.

Connect the Suction Hose

Apply thread sealant to the suction hose (12) and screw it into the bushing (8) at the pump’s fluid intake. Screw the elbow (14) onto the other end of the hose, and screw the suction tube (24) into the elbow.

Connect the Fluid Hoses and Gun

NOTE: Model 238144 includes a Hose and Gun Kit (101), which supplies 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 proper- ly sized and pressure-rated for your system. Use only electrically conductive hoses.

1.Connect the main fluid hose (103) to one fluid shutoff valve (67) at the fluid filter (18) 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 (105).

4.Screw the whip hose (104) onto the gun swivel (106).

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

Assemble Model 238144

1.Assemble the fluid hoses and gun as explained in the preceding paragraph.

2.Mark the date of assembly on the designation plate (107) and install the plate as shown on its separate instruction sheet.
