Disconnect air to motor if leakage
occurs anywhere within system
Failure to comply may result in death
or serious personal injury
Initial prime
1 Place pump in fluid to be dispensed
2 Direct hose into appropriate collection
container and connect product hose to
pump fluid outlet
3 Screw connector (2) with thread sealant
into inlet of air motor assembly Tighten
connector securely
4 Install air coupler (3) onto air supply line
5 Make sure air pressure at regulator
reads zero
6 Connect air coupler assembly to
connector
7 Slowly supply air pressure to pump
motor
8 Allow pump to cycle slowly until fluid is
free of air
If pump assembly does not prime, refer to
Troubleshooting, page 11 for details
Starting pressure
9 Set air pressure to 25 psi (1.7 bars)
10 Insert adjusting bar through slot in
air motor tube and into a hole of
packing screw
11 Adjust packing screw until pump
assembly stops
12 Loosen packing screw until pump
assembly begins to cycle
Leakage and stall
With air pressure at zero:
13 Attach control valve to outlet hose of
pump
13.1 Make sure nozzle on control valve
is open
14 Slowly supply air pressure to pump
motor
15 Allow pump to cycle slowly until fluid is
once again free of air
16 Set air pressure to normal operating
pressure
17 Operate control valve into container
18 Shut off control valve
18.1 Visually inspect pump for external
