ATTENTION!: Risk of scalding.
The expansion tank is supplied with a pressure relief valve in
the cap with 500 mbar. It is possible when operating the gener-
ator hot cooling water can leak here if there is an overpressure.
When working always wear protective clothing and ensure an
adequate installation location.
