1. Description of the appliance

The instantaneous water heater CDX 7-U / CDX 11-U is a electronically controlled,
pressure-resistant water heater for a decentralised water supply to one or more tap
connections.
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 keeping 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 hap-
pen 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.
