Precautions before maintenance
Alcatel Vacuum Technology France - ATP User’s Manual
1/1
GB 00437 - Edition 01 - March 97
It is important to isolate the machine from the electrical power supply source
before any intervention inside the equipment (for maintenance reasons).
Before any maintenance operation, check the pumping conditions of the
installation: toxicity, possible corrosion of the pumped gases. Depending on the
case, we recommend:
- to purge the pumping installation with dry nitrogen before any intervention;
- to wear gloves, goggles and breathing masks, if necessary;
- to ventilate the room well and disassemble the equipment under a fume hood.
After a complete maintenance operation, it is recommended to perform a
helium leaktightness test.
Similarly, follow all the safety instructions concerning start-up.
