GENERATING PRESSURE
Follow these steps to use the pump.
1 Turn the spindle counterclockwise to the stop.
2 Loosen the adjustment screw and turn the banjo set to the desired position. Firmly tighten the screw.
3 Remove plugs using a 6mm Allen key, and fill with test fluid (if necessary).
4 Connect the optional extension tube, pressure hose, and other connection fittings, as needed.
!
CAUTION: USE BONDED SEALS only, for attachment of any part or object directly to the manifold. Tighten all connections firmly.
5 Turn the spindle until test fluid is evident at the top of the connection fittings.
6 Connect the reference indicator and the device under test. Tighten the threads firmly.
Note: If CPF fittings are used in your pressure system, remaining air can be purged through the weep hole, by applying 10 psi or less and loosening the CPF
fitting closest to the pressure device about two and a half turns. Repeat this process for each pressure device in the pressure system which is connected
to a CPF fitting.
7 Power on the reference indicator and the device under test.
8 Confirm there is no pressure in the system by removing the plug or by opening the isolation valve (if installed).
9 Zero the reference indicator and the device under test.
10 If the isolation valve is not installed, replace and tighten the removable plug. If the valve is installed, close it tightly.
11 Verify the system connections are tightened firmly and pressurize the system by turning the spindle clockwise until the approximate pressure is obtained.
12 Allow time for the adiabatic effect to stabilize.
13 Use the fine adjust knob, if installed, to obtain the exact calibration pressure.
14 After obtaining your readings, release pressure by turning the pump spindle counterclockwise until it stops.
15 Open the isolation valve, or remove the plug, to vent the system.

WARNING: The device under test and the reference instrument should only be removed when there is no pressure in the system.
