•
Comply with permissible ambient temperatures and the warning labels on the
pressure reducers.
•
Fit the test gas cylinders with pressure reducers and place them near the analyzer
cabinet. Short test gas lines result in short lag times.
•
Connect the test gas lines to the bulkhead connectors provided for this purpose on
the right wall of the cabinet.
•
Connect the exhaust gas line to the bulkhead connector provided for this purpose
on the right wall of the cabinet (using the shortest possible line with an I.D. ≥ 8 mm).
Allow the exhaust air to pass freely and do not install reduction sections or shutoff
valves. The diameter of the exhaust gas line should be widened at the shortest
possible distance outside the cabinet to prevent any backpressure due to long line
length.
