Gas Supply Requirements
The instrument must be connected to a regulated supply of clean dry air (
>
-20 C dew point) or
nitrogen at 35–120 psig (2.4–8.5 bar).
Note: To minimize the likelihood of water contamination, it is recommended that the inlet
gas be filtered with an external coalescing filter.
Gas Inlet Connection
To Gas Supply
•
Do not remove the gas inlet filter or damage to the instrument may result.
• Connect a regulated supply of clean dry air or nitrogen, 35–120 psig (2.4–8.5
bar), to the inlet tubing assembly of the instrument using the ¼” NPTF side of the
gas filter.
• Supply at least 15 psi (1.02 bar) more than the maximum pressure required to
perform the filter test.
To Instrument
•
Slide quick disconnect fitting of Integritest Exacta inlet tubing assembly onto the
connector stem labeled Air Inlet.
•
Grasp the rear of the connector and push it firmly against the connector stem. Do
not grasp the flared section when making a connection. This section must be able
to slide freely into place
•
Release it when you hear it click into place.
