CAUTION! Operation of the API 4000 instrument requires that, if house gases are
being supplied, each supply be separately regulated at the instrument.
The preferred gas line connections are compression fittings. Liquid pipe sealant is not
acceptable for gas line connections. If threaded fittings must be used, only Teflon tape is
acceptable for sealing the threads. Soldered fittings are not acceptable unless the tubing is
thoroughly cleaned afterward.
