General Safety Considerations

The following safety items must be observed to avoid personal injury and to prevent
damage to the ta7000F Monitor. All personnel involved in installation, operation or
service of the ta7000F should be thoroughly familiar with these items. These consider-
ations are in addition to all site specific safety procedures.

Since Hydrogen is flammable and can be explosive if confined, do not operate
Flame Ionization Detection (FID) equipped instruments without an external
shut-off valve on the hydrogen line. Periodically check that the shut-off valve
operates correctly when the FID flame goes out.
Also, in FID-equipped instruments do not provide hydrogen flow unless carrier
gas is also flowing. In any application using hydrogen, be sure to turn Off the
supply at its source when removing any portion of the H
forming service procedures, etc. Should gas flow measurements through an
FID be required, do not measure air and H
separately to minimize explosion hazard.
Be sure that the top cover is securely in place before operating the ta7000F.
Since some service procedures require the cover to be removed while the
power is On, be aware that electric shock can occur. Therefore, only trained
or otherwise qualified personnel should service the ta7000F. The ta7000F is
supplied with a 3-conductor power cord providing a protective earth ground
connection when plugged into a properly wired receptacle. Proper receptacle
grounding must be verified.
