water out connections. These shut-off valves are field supplied.

However, make sure there is no valve between the pressure relief valve (field
supply) and the DHW tank.

To avoid damage to the surroundings in case of water leakage, it is recommended to
close the domestic cold water inlet shut‑off valves during periods of absence.
