General Operating Notes
GENERAL OPERATING NOTES
• The unit must be installed in a clean and dry area, protected from strong vibrations and frost
.
• The unit must not be exposed to direct sunlight and sources of heat. Admissible ambient
temperatures (see technical details) must be adhered to.
• Gas inlets and
outlets must not be interchanged. All gases must be conditioned, before sup
-
plied to the unit. When using this unit with corrosive sample gases, ensure that these gases
do not contain components harmful to the gas lines.
• Admissable pressure for all applied gases is 1100 hPa (1.45 psig) maximum, for higher
pressure up to 1500 hPa (7.25 psig) consider special ordering code and special conditions
for safe use!.
• Exhaust lines must be laid inclined downwards, depressurized, protected from frost and
according to applicable regulations.
• If it is necessary to disconnect the gas lines, the unit’s gas connectors must be sealed with
PVC caps to avoid polluting the internal gas lines with condensate, dust, etc.
• To ensure electromagnetic compatibility (EMC), only shielded cables (supplied by us on re
-
quest, or of equivalent standard) may be used. The customer must ensure that the shielding
is correctly fitted. Shielding must be electrically connected.
•
The user has to add cable glands to connect power and signal wires to the flame proof en
-
closure.
•
For the measurement of flammable gas the costumer has to install suitable gas path and has
to perform leak tests regularly.
FLAMMABLE GASES – EXPLOSION HAZARD
Leaks may cause explosion when measuring flammable gases!
When measuring flammable gases it is recommended to perform a leak test
on all gas paths, connections and components before startup or applying
power. Leak tests should be carried out on a 2 month’s regular basis and
after repair/maintenance.
See the analyzer instruction manual for instructions on how to carry out
leak tests.
