1. Insert the tube into the tube fitting, and finger-tighten the nut until

the tubing cannot be rotated freely, by hand, in the fitting. (This
may require an additional

turn beyond finger-tight.)

2. Hold the fitting body steady with a backup wrench, and with

another wrench rotate the nut another 1

turns.

SAMPLE IN: In the standard model, gas connections are made at the

SAMPLE IN

and

EXHAUST OUT

connections. Calibration gases must be

Tee'd into the Sample inlet with appropriate valves.

The gas pressure in should be reasonably regulated. Pressures between

3 and 40 psig are acceptable as long as the pressure, once established, will
keep the front panel flowmeter reading in an acceptable range (0.1 to 2.4
SLPM). Exact figures will depend on your process.

If greater flow is required for improved response time, install a bypass

in the sampling system upstream of the analyzer input.

Note: If you have the –V option, The above numbers apply instead to

the vacuum at the EXHAUST OUT connector, described be-
low, with minus signs before the pressure readings.

ZERO IN and SPAN IN: These are additional ports, included on

models with the -C option, for inputting span gas and zero gas. There are
electrically operated valves inside for automatic switching between sample
