8  Maintenance 

8.1  Low level protection 

 

 

Evaporation may cause a slowly water loss. If 
the level is lower than app. 20 mm, a mechan-
ical safety temperature limiter cuts off the 
complete voltage supply. 

 

If lack of water was the problem, the limiter 
can be deactivated once water has been add-
ed.  

 

To do this, press the button at the rear of the 
water bath until a noticeable latching occurs.  

8.2  Unlock the safety temperature limiter 

Two sensors monitor the temperature on the bottom of the bath. 

If the temperature on the bottom of the tank reaches above 110 °C, the LED display indicates: 

E1

Immediately switch off the device with the mains switch and rectify cause of fault. Frequently it is a low 
water level in the tank (

 7.4)

 

 

Above approx. 150 °C bottom temperature a 
mechanical safety temperature limiter cuts off 
the complete voltage supply. Thereupon the 
LED display goes out.  
This protective device is not self-cancelling 
according to DIN EN 61010-2-10.  

 

First, the cause of the overtemperature must 
be found. If lack of water was the problem, the 
limiter can be deactivated once water has 
been added.  

 

To do this, press the button at the rear of the 
water bath until a noticeable latching occurs.  

 

 

The safety temperature limiter must not be deactivated when a mechanical or electri-
cal fault is suspected.  
If necessary, contact the authorized LAUDA Service agents or the LAUDA Service 
Constant Temperature Equipment (

 8.6)

8.3  Cleaning 

 

 

Withdraw the equipment mains plug before cleaning! 

Cleaning can be carried out with water to which a few drops of surfactant (washing-up liquid), have 

been added and using a damp cloth.
