> Inform your heating specialist company if your
electronicVED plus is not working correctly.
Risk of death from electric shock from live lines and
connections!
The drinking water used must demonstrate resistance
greater than or equal to 900 ohm at 15 °C. Otherwise
the unit must not be used.
> Before installing the unit, ask the competent person
at your local water company to inform you about the
water resistance and conductivity.
> Consult your competent person if you have any doubt
as to the requirements for water quality.
Risk of being scalded by hot water!

> Consult a competent person if you have any doubt as
to the requirements for water quality.
Risk of frost.
If an electronicVED plus electric instantaneous water
heater is placed out of operation for a relatively long
period of time in an unheated room in cold weather, the
water in the unit and pipes may freeze.
> Consult a competent person if you have any doubt as
to requirements.
> Ensure that your electronicVED plus electric instanta-
neous water heater is installed in a permanently frostfree room.
Material damage to the appliance caused by changes
No changes must be made to your electronicVED plus.
