Follow these steps in order to operate the pump correctly. See the diagram on page 2 for reference..
Connecting to the Pump
1 Remove the fill plug and fill the reservoir approximately 2/3 full of test fluid.
!
CAUTION: Do not use solvents , alcohol, or synthetic fluids that will adversely affect the operation of the pump.
Please refer to the Recommended Test Fluids section on page 10 for more information.
2 Connect and tighten the fill plug.
3 Turn the pressure vent valve and fine adjust knob counter-clockwise until fully open.
4 Prime the system by pumping the movable handle until air bubbles in the reservoir stop.
5 Turn the pressure vent valve clockwise until fully closed. (Close by hand only.)
6 Connect the reference indicator to the reference pressure port per the connection diagrams on pages 8 and 9 .
7 Operate the handle until the test fluid is visible at the end of the pressure hose. Pre-filling the hose will help speed the operating of the pump.
8 Connect the device-under-test to the test pressure port.
Note: If CPF Fittings are used in your pressure system remaining air can be purged by applying 10 psi or less and loosening the CPF fitting closest to the pres-
sure device. When fluid and air escape from the CPF weep hole, that portion of the system is purged. Repeat this process for each pressure device in the
pressure system which is connected to a CPF fitting.
