Make the connection to the draining system, avoiding connection in a closed circuit shared by
other pressurized discharge lines. Check the correct fl ow of condensate discharges. Dispose of all the
condensate in conformity with current local environmental regulations.
4 Commissioning
4.1 Preliminary checks
Before commissioning the dryer, make sure:
• installation was carried out according that given in the section 3;
• the air inlet valves are closed and that there is no air fl ow through the dryer;
• the power supply is correct;
• with Wc version, open the cooling water circuit a few minutes before starting the dryer.
4.2 Starting
1. switch the power on by turning the MAIN SWITCH “
