flows in the range of 500 to 2000 ccm during normal operating
pressures.
For vacuum service (5-10 in Hg), the low-pressure restrictor can be
used but it is attached to the Exhaust Out port.
Warning:
Operating the unit without restrictors or any flow
control can cause damage to the micro-fuel cell.
The unit is manufactured with 1/8-inch tube fittings, For a safe
connection:
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 1/8 turn beyond
finger tight.)
2. Hold the fitting body steady with a backup wrench, and with
another wrench rotate the nut another 1-1/4 turns.
SAMPLE IN:
In the standard model, gas connections are made at the

EXHAUST OUT
standard model (without auto calibration) the calibration gases must be
tee'd into the Sample inlet with appropriate valves. The standard
analyzer uses 1/8" gas connectors.
The gas pressure in should be reasonably regulated. Pressures
between 2 and 50 psig are acceptable provided the pressure, once
established, will keep the front panel simulated flowmeter display
reading in an acceptable range (100 to 200 CCM). For non-pressurized
sample or very low pressure, (2 psig or less) vacuum service plumbing is
recommended. 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.
EXHAUST OUT:
Exhaust connections must be consistent with the hazard level of the
constituent gases. Check Local, State, and Federal laws, and ensure that
the exhaust stream vents to an appropriately controlled area if required.
