Dust Plugs:
Remove dust plugs from rear panel exhaust and supply line fittings
before powering on/operating instrument. These plugs should be kept
for reuse in the event of future storage or shipping to prevent debris
from entering the pneumatics.

EPA Requirements:
US EPA requirements state that zero air and span gases must be
supplied at twice the instrument’s specified gas flow rate. Therefore,
the 6200T zero and span gases should be supplied to their respective
inlets in excess of 1300 cc
3 /min (650 cc 3 /min. x 2).

Leak Check:
Run a leak check once the appropriate pneumatic connections have
been made; check all pneumatic fittings for leaks using the
procedures defined in Section 11.3.6.
CAUTION – GENERAL SAFETY HAZARD
Gas flow though the analyzer must be maintained at all time for units with
a permeation tube installed. Insufficient gas flow allows gas to build up
to levels that will contaminate the instrument or present a safety hazard
to personnel.
