Technical description

11.19.5 How is controlled the condenser fan

A pressure probe BP2 is located on the discharge side of the compressor. The condenser fan is activated (ON) when
the BP2 pressure is higher than FANon setting (R134a approx. 11 barg/160 psig – R407C approx. 18 barg/260 psig) and
led is ON. Condenser fan stops when BP2 pressure is lower than FANoff setting (R134a approx. 8 barg/115 psig
– R407C approx. 14 barg/203 psig).

11.19.6 How is controlled the drain solenoid valve

Drain solenoid valve is activated (ON) for
