Check the gas connections for tightness. Also
check the line to the fuel cell module. See page 23.
Note
Use only suitable and approved leak detection
agents (EN 14291) and devices for the tightness
test. Leak detection agents with unsuitable constit-
uents (e.g. nitrides, sulphides) can cause material
damage.
Remove leak detection agent residues after test-
ing.

Please note
Excessive test pressure can damage the
appliance.
Max. test pressure 150 mbar (15 kPa).
Where higher pressure is required for tight-
