Work prior to the electrical connection
1 Turn off the power supply switches before starting work and fit the appropriate locks and safety warnings.
2 Wait 5 minutes after turning off the power supply switches.
3 Check that the fans on the indoor and outdoor units are at a standstill before starting work.
N O T E
The electrical power for the unit must involve a specific power line, with an exclusive power control switch and
•
residual current breaker, installed in line with local or national safety regulations.
•
Check that the electrical power line has enough capacity to supply the unit. Its length, the cable diameter and
their protection (sleeve or jacket) must be appropriate for the unit.

Loose connection terminals may lead to cable and terminal overheating. The unit may operate incorrectly,
leading to a risk of fire. Check that the cables are firmly secured to the connection terminals.
