The pigtail fuses (slow blow fuse 6.3 A) are built in wires (1,
black and blue) inside the terminal box. To replace the fuses
it is possible to replace the whole wires (fixed with flat pin
bushes (2)).
➨
Open the terminal box. Unscrew the four screws with a
Torx screw driver TX20 and remove the terminal box cov-
er. Remove the wire with the blown fuse (fixed with flat
pin bushes (2), see figure). Mount the new wire (flat pin
bushes) and close the terminal box. Fasten the cover with
the four screws.

Important: Check operability and safety after repair.
Check the electrical safety (protective conductor resistance, insulating
resistance, high voltage test) according to IEC 61010 and national regula-
tions.
The replacing of the device fuse has to be carried out by an
electrician. Switch off
the pump and disconnect it from mains before opening the terminal box. After dis-
connecting from mains wait two minutes to allow the capacitors to discharge. After
replacing the fuse, the pump must be checked for electric safety (see below)! Identify
and eliminate the cause of failure before switching on the pump again.
