Tightness test

 1 

 Shut off the downstream pipeline close to the 

valve.

 2 

 Open the valve and the medium supply.

 

Check all used ports for tightness.

Maintenance

In order to ensure smooth operation: check the tight-
ness and function of the DG every year.

 

After carrying out the maintenance work, check 

for tightness, see page 4 (Tightness test).
