Operation instruction

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 the appliance

The E-basic instant water heater DBX Next is a electronically controlled pressure-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 auto ma tically.
When the tap is closed, the appliance automatically switches off.
Its electronic control regulates the power consumption depending on the selected outlet temperature, the respective inlet temperature and the flow rate, thus reaching the set temperature exactly to the degree and keeping it constant in case of water pressure fluctuations.
The factory set outlet temperature is 50 °C. This factory setting can be adjusted in the appliance to be in a range of approx. 30 °C and 60 °C by a specialist only.
Note: The hot water temperature may not exceed 55 °C if the instant water heater is connected to a shower.
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.
It is possible to use the instantaneous water heater in combination with an external load shedding relay for electronically controlled instantaneous waterheaters (refer to installing instructions).

How to use

Venting after maintenance work
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.

Disconnect the instantaneous water heater from the mains (e.g. via deactivating the fuses).
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.
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.
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.
The appliance activates the heater after approx. 10 seconds of continuous water flow.

Cleaning and maintenance

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 operational safety at all times.

Trouble-shooting and service

Repairs must only be carried out by authorised professionals.
If a fault in your appliance cannot be rectified with the aid of this table, please contact the service organisation of your importer or the Central Customer Service Department. Please have the details of the typeplate at hand.
