6. STARTUP
Before start-up:
• Check that the diagrams and manuals of the installed machine are available.
• Check that the wiring and plumbing diagrams of the plant the machine is connected to are available.
• Check that the shut-o valves of the water circuits are open.
• Check that the water circuit was lled under pressure and the air vented.
• Check that all hydraulic connecons are correctly installed and that all indicaons on the rang plates are respected.
• Make sure that measures have been taken to discharge condensate.
• Check the electrical connecon and correct fastening of all the terminals.
• Check that the electrical connecons have been made according to standards in force, including earthing.
• Voltage must match that on the unit’s rang plate.
• Make sure that the electric voltage is within the tolerance limits (±5%).
• Check that the electric heaters of the compressors are properly powered.
• Check that there are no gas leaks.
• Before switching the unit on, check that all panels are posioned correctly and well-xed with screws.

To supply power to the machine, turn the external handle of the disconnector to the ON posion (marked "I"). The display on the machine will
only light up if the phase sequence is correct (check during inial start-up).
Wait at least 1 minute between switching o and switching on.

We recommend keeping track of the intervenons carried out on the unit so as to make any troubleshoong easier.
In case of failure or malfunconing:
• check the type of alarm triggered to report it to the assistance centre;
• contact an authorised assistance centre;
• if requested by the assistance centre, immediately deacvate the unit without reseng the alarm;
• request that original spare parts be used.
SHUTDOWNS FOR LONG PERIODS
The shutdown mode of the plant depends on the site of applicaon and the me the plant is expected to be shut down. If the unit is equipped
