An organized service must check the electrical, hydraulic, and refrigerant components as a whole.
1. Cleaning
External exchanger, water filters, and airflow areas.
2. Hydraulics
Flow rate, ΔT, pressure, expansion vessel, circulator, and leak tightness.
3. Electrical
Power supply, terminals, protection devices, and alarm history.
4. Sensors
Comparison of basic temperatures and operational logic check.
5. Final test
The unit operates under real load and basic measurements are recorded before the service is completed.
