WARNING

Bleed-Type Master Air Valve and Fluid Drain Valve

A bleed-type master air valve and a fluid drain valve are required on your system.

The bleed-type master air valve relieves air trapped between itself and the pump. Trapped air can cause the pump to cycle unexpectedly, which could result in serious bodily injury, including splashing in the eyes, injury from moving parts, or contamination from hazardous fluids.

The fluid drain valve reduces the risk of serious bodily injury, including splashing in the eyes or on the skin, or contamination from hazardous fluids. Install the fluid drain valve close to the pump’s fluid outlet to relieve pressure in the hose if the hose becomes plugged.

1.Mount the air line accessories on the wall or on a bracket. Be sure the air line supplying the acces- sories is grounded.

a.The pump speed can be controlled in one of two ways: To control it on the air side, install an air regulator. To control it on the fluid side, install a fluid valve near the outlet.

b.Install a bleed-type master air valve down- stream from the air regulator, and use it to re- lieve trapped air. See the Bleed-Type Master Air Valve and Fluid Drain Valve warning above. Locate another bleed-type master air valve upstream from all air line accessories, and use it to isolate the accessories during cleaning and repair.

c.The air line filter removes harmful dirt and moisture from the compressed air supply.

2.Install a flexible air hose between the accessories and the pump air inlet. Screw the air line fitting into the air inlet.

3.Do not restrict the exhaust port. Excessive ex- haust restriction can cause erratic pump operation.

Fluid Lines

Fig. 3. On each end of the fluid manifold are a fluid IN port and a fluid OUT port. NOTE: Make sure the fluid OUT port on the fluid manifold is mounted up. This will assure proper pump priming. Fluid-inand fluid- out lines can be connected on the same end, or opposite ends of the manifold. Plug ports that are not used (plugs provided).

Typical Installation

The installations shown in Fig. 4 are only a guide to help select and install a pump; they are not actual system designs.

Typical installation includes (not supplied by Graco):

DFor solenoid operation: a four-way, 5-port, 3-posi- tion solenoid valve with 1/4-in. ports, or two 3–posi- tion 3–way valves. Mac series 44 (4–way), or series 35 (3–way). Either way, air pressure should be released if not cycling.

DPLC or timer. Consult your local industrial controls distributor.

CAUTION

For solenoid operation, the pump must exhaust through the solenoid. Failure to exhaust through solenoid could cause the diaphragms to fail.
