5.2 Packaging
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during transport (e.g. change
in installation site, sending for repair).
5.3 Storage
■ Only store the portable SF
6
gas transfer unit in an upright position.
■ The instrument should only be lifted using the transport handles.
Permissible conditions at the place of storage:
■ Storage temperature: -20 ... +60 °C
Avoid exposure to the following factors:
■ Direct sunlight or proximity to hot objects
■ Mechanical vibration, mechanical shock (putting it down hard)
■ Soot, vapour, dust and corrosive gases
■ Potentially explosive environments, flammable atmospheres
6. Commissioning, operation
CAUTION!
Prior to commissioning, the GTU-10 must be subjected to a visual inspec-
tion. The housing should not be corroded and not be opened, so that the
compressor can be started. Operating the instrument without the metal
cladding is prohibited. Only use the instrument if it is in perfect condition
with respect to safety. The GTU-10 has undergone a complete functional
test in the factory and been filled with dry nitrogen to a transport pressure
of approx. 1.2 bar abs. before delivery.
To check the leak-tightness of the connection components and hoses, an
SF
6
gas leak detector should be used (e.g. model GIR-10).
In the event of any leakage from the lines carrying SF
6
gas, the system
must be stopped immediately and the leaks must be eliminated by quali-
fied personnel.
CAUTION!
When using gas cylinders, the valve must be protected by a safety valve.
Furthermore, the safe standing of the gas cylinder must be ensured. Use
only approved adapters, hoses and fittings for the connected cylinder
types. There is a risk of accidents when using incorrect equipment.
It is important to be aware that up to 40 bar abs. can be present at
the unreduced outlet. This connection is not suitable for the filling of
equipment that has not been designed for at least 40 bar abs.
