Close the vent valve.
Note:
If using the T-1-CPF, fill with test fluid through the gauge connections. This may take approximately 15 minutes.
Note:
It may be necessary to prime the pump, particularly for first time use, or if the pump has been inactive for an extended period of time.
Refer to
for instructions on priming the pump.
4
Pull the pump handle to the top of its stroke.
5
Pull out the valve rod selector to select the low pressure/high volume setting.
6
Gently operate the pump handle until test fluid fills the top of the pressure ports on the pressure manifold.
Note:
Lightly tap the column and/or the manifold to make sure that any air bubbles sticking to the walls or in low flow areas are released to float to
the surface.
7
Attach the reference instrument and the device under test to the manifold.
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.
!
CAUTION: Always choose a reference instrument with a range equal to or greater than the range of the device under test.

Ensure all connections are tight and leak free.
