Instructions for user - DBX Next - August 2021 v1.00 Art.no: 9120-34376
The E-basic instant water heater DBX Next is a electronically controlled pres-
sure-resistant instantaneous water heater for an efficient water supply to one
or more tap outlets.
As soon as you open the hot water tap, the instantaneous water heater
switches on automatically. When the tap is closed, the appliance automati-
cally switches off. Its electronic control regulates the power consumption
automatically depending on the feed temperature and the flow rate, thus
reaching the set outlet temperature up to the appliance’s power limit.
The factory set outlet temperature is 50 °C. This factory setting can be adjust-
ed in the appliance to be in a range of approx. 20 and 50 °C by a specialist
only.
In case of a low feed temperature and a high flow rate at the same time, it
could happen that the preset outlet temperature is not reached which is due
to the fact that the appliance exceeded its capacity. The outlet temperature
can be raised by reducing the water flow at the tap.

2. How to Use
This instantaneous water heater features an automatic air bubble protection
to prevent it from inadvertently running dry. Nevertheless, the appliance
must be vented before using it for the first time. Each time the appliance is
emptied (e.g. after work on the plumbing system, if there is a risk of frost
or following repair work), the appliance must be re-vented before it is used
again.
1. Disconnect the instantaneous water heater from the mains (e.g. via deacti-
vating the fuses).
2. Unscrew the jet regulator on the outlet fitting and open the cold water tap
valve to rinse out the water pipe and avoid contaminating the appliance or
the jet regulator.
3. Open and close the hot water tap until no more air emerges from the pipe
and all air has been eliminated from the water heater.
4. Only then should you re-connect the power supply again (e.g. via activating
the fuses) to the instantaneous water heater and screw the jet regulator
back in.
5. The appliance activates the heater after approx. 10seconds of continuous
water flow.
Venting after maintenance work
• Plastic surfaces and fittings should only be wiped with a damp cloth. Do not
use abrasive or chlorine-based cleaning agents or solvents.
• For a good water supply, the outlet fittings (e.g. jet regulators and shower
heads) should be unscrewed and cleaned at regular intervals. Every three
years, the electrical and plumbing components should be inspected by an
authorised professional in order to ensure proper functioning and opera-
tional safety at all times.
