8  Maintenance 

Leak detectors are safety equipment; if damaged, they may only be 

repaired by the manufacturer. 

8.1 

Maintenance times 

It is recommended to close a maintenance agreement with a com-

pany specialised/certified according to the applicable water protec-

tion regulations. 

Table 4: Maintenance times 

When 

Activity 

Annually 

 

Perform a function test by simulating an alarm 

condition 

At regular in-

tervals 

 

Verify that the leak detector and its environ-

ment are always clean, accessible and easy to 

oversee 

 

8.2 

Maintenance activities 

Replacing the mains fuse F1 

 

Mains voltage is interrupted and cannot be switched on. 

1.  Open the control unit, see chapter 6.6, page 24. 
2.  Remove the transparent cover from the mains fuse F1. 
3.  Replace the mains fuse F1, see table 2, page 15. 
4.  Snap the transparent cover onto the mains fuse F1. 
5.  Connect the flat cable to the connector. 
6.  Close the control unit, see chapter 6.6, page 24. 
7.  Switch on the mains voltage.
