4. Before connecting the TESCOM EUROPE WegaMed Compact, slowly open the valve
on the compressed gas cylinder briefly in a well ventilated room or outdoors (this is
to blow out any contamination).
Pressure surges caused by opening the valve too quickly can cause
explosions! to avoid the risk of injury, the gas jet must be directed
away from any persons in the vicinity.
5. Remove the protective caps covering the connections on the pressure regulator and
keep them in a safe place.
6. Screw the TESCOM EUROPE WegaMed Compact to the compressed gas cylinder.
The connections must match -
do not use adapters!
all connections must be clean and free from oil and grease. Do
not use lubricants.
handwheel connection
The pressure regulator can be fitted with a handwheel connection to make it easier to
connect it to the cylinder valve. This connection is denoted by the knurled connection screw
or nut and the elastomer gasket inside one of the grooves on the coupling connection.
When making the connection, it is absolutely essential to check the gasket for evidence of
damage and soiling. If the gasket is damaged or soiled, the pressure regulator must not be
used and has to be replaced. (Chapter 5.2.3 "Replacing gaskets"; ordering information
appears in Chapter 7.5.)
Please note that this screw connection needs to be made without using tools.
As soon as the compressed gas cylinder is opened, the compressed gas pushes the gasket
into the annulus between the valve on the compressed gas cylinder and the pressure
regulator. This creates a reliable seal.
The connection must be depressurised when the coupling is unfastened. It is strictly forbidden
to unfasten the coupling when pressurised and using a tool except in an emergency. This
will damage the gasket beyond repair, necessitating a subsequent replacement.
Check that the pressure regulator and the compressed gas cylinder are securely connected
before
slowly
opening the cylinder valve. If the connection is not leaktight, close the
cylinder valve immediately.
Once the connection has been made correctly, run a performance test (see Chapter 5.2
“Performance test”) to ensure safe and reliable operation.
