9. Allow the full system to operate until it stabilizes.
10. Adjust all expansion valves, EPR valves, control valves, and other controls to
their proper settings.
11. Re-check refrigerant charge and oil levels, adding refrigerant and oil as
needed.
Items to Watch and Check During Start-up
Excessive Vibrations
The whole system, especially the piping and capillary tubes must be designed to prevent
abnormal vibrations. If necessary, additional protective measures must be taken.
Attention!
Pipe fractures and leakages at compressor and other components are possible! Avoid
strong vibrations!
Compressor Cycling Frequency
A compressor should not be started more than 8 times per hour. Therefore a minimum
running time should be guaranteed:
Min.
