Be aware of the following: 

On the three-phase CAE, via the phase controller (KA4), any modification of the order of 
phases on the distribution network or on the existing electrical installation is detected. 
The appliance then goes into fault mode (“alarm triggered” led lit), see § 2.1. 

The appliance must have a filter fitted when operating. 

Appliance powered off and decommissioned! 

A general servicing of the appliance is strongly recommended to check the proper 
operation of the appliance, maintain its performance, to avoid certain faults and preserve 
the building in good condition.
