Safe use of burner gases
The seepage of fuel gas or fuel gas mixture from the burner system, the drain system, the gas
control system, or the gas connections constitutes a serious fire hazard.
If you suspect that the gas box has been damamged (for example, using the
acetylene tank below 85 psi) do not use the instrument until it has been
inspected by a PerkinElmer Service Representative.
WARNING
•
Make sure that there are no breaks or leaks in any of these systems and that all the seals
are correctly installed and in good condition.
•
Regularly check for leaks at joints and seals using an approved leak test fluid.
•
When you perform any maintenance or installation procedures, follow the instructions
in the guide exactly.
•
Do not attempt to service the gas control system yourself. A PerkinElmer service
engineer, or similarly authorized and trained person, must perform the work.
When you shut down the instrument, for example at the end of the working day, shut all the gas
lines at the cylinder or regulator valves. Bleed the lines between the regulator and instrument to
atmosphere before switching off the exhaust venting system.
Warning: Flashback Hazard
PerkinElmer burner systems are designed for use with compressed air. The
use of oxygen can cause an explosion in the burner system. And oxygen-
WARNING
