M 3..7 E-mini Instant Water Heater

Note: Carefully read the enclosed safety instructions through in full before the appliance is installed, put into service and used and follow them in the further steps and during use!

Description of appliance

This instantaneous water heater is intended to provide the economical heating of water sufficient for a single outlet, i.e. handwash basin, and must be connected to a special open-outlet tap to avoid any overpressure. When the hot water tap is opened, the instantaneous water heater switches itself on automatically and heats the water as it passes
through the  appliance. It is only then that the appliance useselectricity. The temperature increase depends on the flow rate.
