Fuel Requirements
The CAI factory configures the 700M HFID analyzer for either 100% Hydrogen or 40%/60%
Hydrogen/Helium fuel. Please make sure to use the correct fuel as specified on the fuel label
affixed to the back panel of the analyzer.
WARNING:
Use of incorrect fuel will damage the instrument and could cause an explosion.
Before initial startup, carefully check the fuel supply system to the analyzer for leaks. The
operating technician should be properly trained for working with hazardous materials.
Potential Sample Pump Damage
The analyzer can be calibrated using the optional zero and span gas ports located on the back
panel. It can also be calibrated using the internal sample pump. Care must be taken to ensure that
the sample pump is not exposed to excessive pressure using this calibration method. Any
pressure exceeding 2.0 psig can result in a NON-WARRANTY failure.
Removing Protective Caps
Do not apply AC power to this analyzer until you have removed the plastic ¼-inch caps from the
sample/zero/span/fuel fittings on the rear panel. Failure to remove these caps will result in
analyzer contamination.
Filter Housing Maintenance
1.
Whenever you replace the filter element, always apply a liberal coating of hydrocarbon-
free silicone lubricant to the threads of the filter housing before re-assembly to prevent
galling and seizing of the threads.
NOTE:
Use a silicone lubricant that is free of hydrocarbons to eliminate contamination
of the analyzer and measurement errors.
