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 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.
Mountings
• Be sure the mounting surface can support the
weight of the pump, hoses, and accessories, as well
as the stress caused during operation.
• For all mountings, be sure the pump is bolted
directly to the mounting surface.
• For 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.
• Rubber Foot Mounting Kit 236452 is available to
reduce noise and vibration during operation.
• Prolonged exposure to UV radiation will degrade
natural polypropylene components of the pumps. To
prevent potential injury or equipment damage, do
not expose pump or the plastic components todirect
sunlight for prolonged periods.
Fluid Suction Line
1. The pump fluid inlet (R) is a 2” raised face flange.
Refer to Flange Connections on page 10.
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 36 for maximum
suction lift (wet and dry).
Fluid Outlet Line
1. The pump fluid outlet (S) is a 2” raised face flange.
Refer to Flange Connections on page 10.
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.
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 12
WARNING
A bleed-type master air valve (B) is required in your
system to relieve air trapped between this valve and
the pump. Trapped air can cause the pump to cycle
unexpectedly, which could result in serious injury,
including splashing in the eyes or on the skin, injury
from moving parts, or contamination from hazardous
fluids. See Fig. 2.
