Electrical motor wiring
In all cases the instructions shown on the cooler's connection box must be adhered to.
The standard three phase motors are high-resistant.
The protection factors are given with purge holes closed (CEI 34-5).
Important
: the maximum imbalance between phases is 2% in voltage and 10% in current per motor.
Electrical defrosting
The defrosting heaters are 230V/1/50Hz elements wired in 400V/3/50Hz star.
For use in chambers at 0°C, the coil must be defrosted electrically.
For use below 0°C, heaters must be included in the defrost tray.
The defrost heaters are fitted inside copper sleeves and the ends closed by two clips.
The defrost thermostats or limiters must be set at the threshold of the ambient air temperature.
Any water drain pipes must be fitted with drain line heaters.
