7 Adjustment of the SF6 gas pressure
7.1 General instructions for handling and storing gas bottles under pressure
Ensure that the gas tap is in good
condition and is protected by a
protective cover.
Avoid shocks.
Do not expose the bottles to a
temperature higher than +50°C.
The SF6 gas bottles must be
stored away from corrosive
agents (water, water vapour, saline
atmosphere, pollution of all kinds).
7.2 SF6 filling and pressure checking kit (supplied as an option)
The SF6 filling kit comprises:
- an SF6 gas bottle,
- a pressure reducing valve,
- a pressure gauge,
- a connection hose,
- a protection net (or cover),
- this instruction manual.
7.3 Preparation of the pressure adjustment tools
Unscrew the protective cover
from the SF6 gas bottle.
Loosen and remove the
protective nut from the orifice of
the gas output (open-ended
spanner, size 30).
Fit in position the seal before
screwing the refilling pressure
reducing gauge (light tightening,
by hand).
