Installation
Installation of Remote Pilot Air Lines
1.Refer to Parts Drawings. Connect air line to pump as in preceding steps.
2.Connect 1/4 in. O.D. tubing to push type connec- tors (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.
Mountings
CAUTION
The pump exhaust air may contain contaminants. Ventilate to a remote area if the contaminants could affect your fluid supply. See Air Exhaust Ventilation on page 11.
DBe sure the mounting surface can support the weight of the pump, hoses, and accessories, as well as the stress caused during operation.
DFor all mountings, be sure the pump is bolted directly to the mounting surface.
DFor ease of operation and service, mount the pump so the air valve cover (2), air inlet, and fluid inlet and outlet ports are easily accessible.
DRubber Foot Mounting Kit 236452 is available to reduce noise and vibration during operation.
Fluid Suction Line
1.The pump fluid inlet (R) is a 2” raised face flange. Refer to Flange Connections on page 9.
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.
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 34 for maximum suction lift (wet and dry).
Fluid Outlet Line
WARNING
A fluid drain valve (J) is required to relieve pres- sure in the hose if it is plugged. The drain valve reduces the risk of serious injury, including splash- ing 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 Fig. 2.
1.The pump fluid outlet (S) is a 2” raised face flange. Refer to Flange Connections on page 9.
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.
