The first start-up must confirm that the hydraulic network is truly ready before the compressor is loaded.
1. Pressure
Check the filling pressure and the expansion vessel pre-charge.
2. Flow
Measure the actual flow rate and compare it with the manufacturer's requirement.
3. Filters and air purging
Confirm that the filter is clean and the network is fully purged of air.
4. ΔT
Record supply temperature, return temperature, and ΔT during steady-state operation.
5. Tightness
Check all connections for leaks.
6. Valves and circulators
Confirm the correct direction, position, and operation of all critical components.
