Installation 5.15 Electrical wiring Notes on safety for the electrical wiring The electrical wiring must be carried out with the electrical supply disconnected. Electrical wiring must be made in accordance with the regulations currently in force in the country of destination and by qualified personnel.
Installation Before carrying out any maintenance, cleaning or checking oper- ations: Turn off the burner's electrical supply using the main system switch. DANGER Turn off the fuel interception tap. DANGER Avoid condensate, ice and water leaks from form- ing. DANGER If the cover is still present, remove it and proceed with the electri- cal wiring according to the wiring diagrams.
Installation 5.15.3 Shielding the connections For the burner to operate correctly, where re- quired, it is necessary to shield the connections. WARNING To shield the motor connection, proceed as follows: to access the motor casing, loosen the four screws 1)(Fig.
