DANGER!
Safety valve outlet
The safety valve outlet must be directed to a canister
with sufficient dimensions in a pipe so nobody is
endangered by hot water or steam.
The safety valve outlet must be directed into the
canister via a clearly visible, open route (siphon
funnel) so that malfunctions, especially a failure of
the safety valve to close, can be detected. In the
same way, the frost protection is collected when
opening the safety valve and can be filled again.
