Important note!
The volume of water in the storage heater will expand as it is heated. The expansion water must drip out of the
mixer spout. This process is necessary and normal. The spout must not be fitted with any downstream resistances
in the form of air bubblers (e.g. mousseurs) and components reducing flow (e.g. restrictors) as these will result in
damage to the storage heater.
