Operation with prewarmed water (solar heated)
The continuous-flow heater can only heat prewarmed water to a max. of 60 °C . If the cold water supply exceeds a temperature of 55 °C , the water will not be warmed any further.
Important: The cold water supply temperature must not be higher than 55 °C!
If the cold water supply exceeds a temperature of 60 °C , a circuit breaker will trigger and shut the appliance off. Therefore, the residential plumbing must be equipped with a thermostatic premixer (e.g. special accessory BZ 45T20) that will limit the cold water supply temperature to a max. of 55 °C by appropriately mixing in cold water.
Special accessories
▶Pipe kit BZ 45U20: for use of the continuous-flow heater as an under sink appliance
▶Priority switch (load shedding relay) BZ 45L20: for operation with a priority circuit
Mounting kit BZ 45K23: for surface mount installation
▶Thermostatic premixer BZ 45T20: for installation in the domestic plumbing when using preheated water

A fault, what to do?
If your appliance does not operate as required, it is often due to a very minor problem. Please check whether you can remedy the fault yourself by using the following guidelines. You will save yourself the costs of an unnecessary visit by customer service personnel.
Fault Cause Solution Who
| Water flow-rate is too low. The filter in either the water tap or the showerhead is clogged | Remove the filter and either clean it or descale it. | Customer |
| The filter in the corner regulating valve is clogged. | Get a servicing expert to clean the filter. | Servicing expert |
| The desired water temperature is not reached. | The continuous-flow heater is connected to a thermostatically-controlled water tap. | Set the temperature on the continuous-flow heater to “60°”. |
| The power limit has been reached. Water flow-rate is too high and/or the cold water supply temperature is too low. | Reduce the flow-rate at the water tap supply. | |
| By a qualified professional: use the angle valve to regulate the flow-rate.Check the flow-rate limiter or replace it with a smaller one. | ||
| The water is not sufficiently warm. | The fuse in the house electrical installation has tripped/blown. | Check the fuse in the house electrical installation. |
| The appliance's automatic circuit breaker has been tripped. | Get the appliance's automatic circuit breaker checked by an electrician. Check the permissible supply temperature. | |
| The power limit has been reached. Water flow-rate is too high and/or the cold water supply temperature is too low. | By a qualified professional: use the angle valve to regulate the flow-rate.Check the flow-rate limiter or replace it with a smaller one. | |
| The power selector switch is set incorrectly. | Set the power selector switch to suit the appliance. | |
| From time to time, cold water flows out. | The air sensor in the appliance detects air in the water and momentarily switches the heating element off. | After a few seconds, the continuous-flow heater automatically goes back into operation. |
| Winter operation: The desired water temperature leaving the tap is no longer reached. | The supply temperature has reduced. | Reduce the water flow on the taps until the desired water temperature is reached. |
| The appliance does not start (heat), no water flows | Power failure or initial start-up. | Starts rinsing:Open the warm water tap and allow water to flow for at least 1 minute (flow-rate at least 6 litres per minute). Only then (for safety reasons) will the appliance begin to heat.Should the appliance not start because of a reduced flow-rate, remove the perlator, shower head or similar before start and repeat the process. |
