6 - START-UP

6.1 - PRELIMINARY CHECKS

The indicated operations should be done by qualified technician with specific training on the product.
Upon request, the service centres performing the start-up.
The electrical, water connections and the other system works are by the installer.
Agree upon in advance the star-up data with the service centre.
Before checking, please verify the following:
• the unit should be installed properly and in conformity with this manual
• the electrical power supply line should be isolated at the beginning
• the unit isolator is open, locked and equipped with the suitable warning
• make sure no tension is present
After turning off the power, wait at least 5 minutes before accessing to the electrical panel or any other electrical component.
Before accessing check with a multimeter that there are no residual stresses.
6.2 - PRELIMINARY CHECKS
The following check list is a brief reminder of the points to check and of the operations to perform to start-up the unit.
For details on the points mentioned in the check list refer to various chapters of the manual.
