Water pressure
A minimum of 1,4 bar of water pressure is required for the regeneration valve to operate
effectively.
Do not exceed 8,5 bar; if you face this case, you should install a pressure regulator upstream the
system.
Electrical connection
An uninterrupted current supply is required. Please make sure that your voltage supply is
compatible with your unit before installation. If the electrical cable is damaged, it must
imperatively be replaced by a qualified personal.
Existing plumbing
Existing plumbing should be in a good shape and free from limescale.
The installation of a pre filter is always advised.
By-pass
Always provide a by pass valve for the installation, if the unit is not equipped with one.
Water temperature
Water temperature is not to exceed 43°C, and the unit cannot be subjected to freezing
conditions.
