7 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-off valves of the water circuits are open.
• Check that the water circuit was filled under pressure and the air vented.
• Check that all the plumbing connections are installed correctly and that all the indications on the rating plates are complied
with.
• Make sure that measures have been taken to discharge condensate.
• Check the electrical connection and correct fastening of all the terminals.
• Check that the electrical connections have been made according to standards in force, including earthing.
• Voltage must match that on the unit’s rating plate.
• Make sure that the electric voltage is within the tolerance limits (±10%).
• 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 positioned correctly and well-fixed with screws.
