Installation of Remote Pilot Air Lines
1. Refer to Parts Drawing. Connect air line to pump as
in preceding steps.
2. Connect 1/4 in. O.D. tubing to push type connectors
(14) on air motor of pump.
NOTE: by replacing the push type connectors, other
sizes or types of fittings may be used. The new fittings
will require 1/8 in. npt threads.
3. Connect remaining ends of tubes to external air
signal, such as Graco's Cycleflo (P/N 195264) or
Cycleflo II (P/N195265) controllers.
NOTE: the air pressure at the connectors must be at
least 30% of the air pressure to the air motor for the
pump to operate.
Fluid Suction Line
1. Use grounded fluid hoses (G). The pump fluid inlet
(R) is 1-1/2 in. npt(f). Screw the fluid fitting into the
pump inlet securely.
2. If the fluid inlet pressure to the pump is more than
25% of the outlet working pressure, the ball check
valves will not close fast enough, resulting in
inefficient pump operation.
Installation
3. At inlet fluid pressures greater than 15 psi (0.1 MPa,
1 bar), diaphragm life will be shortened.
4. See the Technical Data on page 33 for maximum
suction lift (wet and dry).
Fluid Outlet Line
A fluid drain valve (J) is required to relieve pressure in
the hose if it is plugged. The drain valve reduces the
risk of serious injury, including splashing in the eyes
or on the skin, or contamination from hazardous fluids
when relieving pressure. Install the valve close to the
pump fluid outlet. See F
1. Use grounded fluid hoses (L). The pump fluid
outlet (S) is 1-1/2 in. npt(f). Screw the fluid fitting into
the pump outlet securely.
2. Install a fluid drain valve (J) near the fluid outlet.
See the WARNING above.
3. Install a shutoff valve (K) in the fluid outlet line.
