11.16.1 Switching the chiller on
Power the chiller and switch it on using the ON-OFF switch (pos.1 Section 11.1).
During normal operation led
ON
is ON and the display shows the DewPoint temperature by means of two coloured
areas (green and red) above a 10 Led display :

Green area - operating conditions ensuring an optimal DewPoint;

Red area - DewPoint too high, the chiller is operating with high thermal load (high inlet air temperature, high ambient
temperature, etc.). Compressed air treatment may be improper.
Led
shows that condensate drain solenoid valve is ON (Not used).
Led shows that condenser fan is ON
The condensate drain test is always active using the button (Not used).
