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
accessories 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 downstream
from the air regulator, and use it to relieve
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 exhaust
restriction can cause erratic pump operation.

Installation
Fluid Lines
F . 3. On each end of the fluid manifold are a fluid IN
IG
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-in and 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 F
select and install a pump; they are not actual system
designs.
Typical installation includes (not supplied by Graco):
•
For solenoid operation: a four-way, 5-port, 3-position
solenoid valve with 1/4-in. ports, or two 3-position
3-way valves. Mac series 44 (4-way), or series 35
(3-way). Either way, air pressure should be released
if not cycling.
•
PLC or timer. Consult your local industrial controls
distributor.
For solenoid operation, the pump must exhaust
through the solenoid. Failure to exhaust through
solenoid could cause the diaphragms to fail.
