Guidelines for prevention of damage
PLEASE STUDY THIS MANUAL THOROUGHLY BEFORE IN-
STALLING OR OPERATING THE INSTRUMENT.
Carrier Gas
The RGD detectors can be destroyed if operated at temperature without
flow. The carrier gas should remain flowing until all heated zones are
below 50o C (2 to 3 hours).
Line Voltage
Do not connect the power cord to line voltage without checking the cor-
rect operating voltage on the label located on the rear of the instrument.
Actuator Gas pressure
Always maintain correct actuator gas pressure. Low pressure (below 70
psig) can result in failure of the internal valves and /or stoppage of the gas
flow to sensitive instrument components. High pressure (above 150 psig)
will damage the valve actuators.
Carrier Gas Purifiers
External gas purifiers must be completely conditioned with gas flowing
through them before connection to the Analyzer. Failure to properly con-
dition purifiers can result in serious contamination.
FID Flame Ignition
Do not ignite the FID flame unless the FID is at operation temperature.
Moisture will condense in an un-heated FID and will short-out the elec-
trometer input leads.
Shut Down
Be sure to turn off all heated zones and shut off the hydrogen supply
to the instrument prior to disconnecting gas supply lines. The carrier
gas should remain flowing until all heated zones are below 50
o
C (2 to 3
hours). After shutting off carrier gas, immediately cap all open rear panel
gas ports.
Electrical Signal cables
Turn power off before connecting or disconnecting electrical signal cables.
Damage to circuit boards could result.
