Filling
Double-walled containers (tanks) are delivered with leak detection
fluid already filled into the interstitial space. The volume of leak de-
tection fluid filled must be known and indicated on the nameplate of
the tank. Only refill the specified leak detection fluid, mixed with wa-
ter in the specified mixing ratio unless you have a certificate of the
BAM (German Federal Institute for Materials Research and Testing)
to the effect that the leak detection fluid you want to fill can be mixed
with the leak detection fluid contained in the interstitial space.

ceptacle below it and remove the probe from the black LAG
container.
2. Remove the filling screw at the black LAG container and fill.
3. Do not close the test valve until leak detection fluid escapes.
4. Fill leak detection fluid up to the overflow opening of the liquid
level mark.
