3. USER MANUAL
The device must be filled with water before connection to
the electrical supply!
When powering up for the first time, you must verify that the
temperature indicator (light) extinguishes when the required
temperature is reached (the device has reached the set tem-
perature). The device only switches on again if the tempera-
ture falls below this setting. (See troubleshooting)
The indicator light is “ON” steadily when the device is in operation.
Important! Purging Air Out
Before switching “ON” the power at the main circuit breaker
panel, make sure that the hot water circuit is free of air pockets
or else premature failure of the element will occur.
Through several simple steps, you can install the appliance and enjoy the endless
hot water supply.
This unit is equipped with a 2-steps power heating element. Therefore the outlet
hot water temperature may vary in connection with inlet water temperature and
flow rate. To get the desired temperature, adjust the hot water flow rate or add
cold water at your mixer. See the below figures and follow the instructions.
Make sure the pressure of your water supply system supersedes the 0,5bar
(0,05MPa).
