Procedure
1. Connect the condensate pump as per the circuit diagram.
- Connect the live wire of the condensate pump to the control fuse (F10) at terminal (2) in junction box 1.
- Connect the neutral wire of the condensate pump to terminal (X1/N5) in junction box 1.
- For size 1: Connect the PE conductor of the condensate pump to terminal (X1/PE5) in junction box 1.
2. Remove the bridge from terminals (X4/3) and (X4/4) in junction box 2.
3. Connect fault signaling contact 1 of condensate pump to terminal (X4/3) in junction box 2.
4. Connect fault signaling contact 2 of the condensate pump to terminal (X4/4) in junction box 2.
