).
3. Install 3/8"
OD
air hose piping with 1/4" NPT fittings from the PPV protected air tank to the primer manually operated push-to-operate
control and then to the primer unit. (See
Figure #14
).
4. If the AirPrime is equipped with an optional lift gauge, connect a 1/4" tubing line from the push-to-connect fitting supplied on the back
of the panel lift gauge to the 1/8" NPT connection on side of the primer body using the 1/8" male NPT x 1/4"

OPERATION: Manual Priming Control
The manual AirPrime pump primer is operated simply by increasing the engine speed to a maximum of 1000 RPM and depressing the push
button on the panel. Hold the button down until the discharge pressure gauge begins to rise. The primer will stop running when the push
button is released. The push button will operate the primer regardless of whether the fire pump is engaged or not.
1. Depressing the Push-To-Prime button directs air to the primer inlet.
2. An internal valve to the water pump is opened with air pressure from chassis air system.
3. Vacuum for drafting is created by air-flow through multi-stage internal venturi nozzles.
4. The Panel Control Valve has no water, plumbing or electrical lines.
5. Never run a dry pump at engine speeds above 1200 RPM for more than 45 seconds in accordance with fire pump manufacturer's
operating instructions.
