Operating instructions
1. Description of the appliance
The instantaneous water heater CDX-U / CDX is a electronically controlled,
pressure-resistant water heater for a decentralised hot water supply to one or
more outlets.
Its electronic control regulates the heating 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 keep-
ing it constant in case of 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: If the water heater supplies a shower, the maximum temperature was
reduced during initial operation. This limitation may not be exceeded.
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.
