24 LIST OF THE RECOMMENDED PERIODIC INTERVENTIONS
GENERAL INTERVENTIONS
DESCRIPTION FREQUENCY
Note 3 Mths 6 Mths 12 Mths
GENERAL INTERVENTIONS
Refrigerant leak control (this operation must be performed with the frequency suggested by current European regulations) •
Unit supply voltage control
•
Compressor supply voltage control
•
Fan supply voltage control
•
Solenoid valve control
•
Pressure switch operation and calibration control, if applicable
