· Service
When storing the compressor, make sure that all connection points are closed so that no moisture or dirt can enter. The connection points should not be opened until immediately before installation.
The only service operations that should be performed on the compressor are replacement of the thermal protection sensor, pressure relief valve and pulley/magnetic coupling assembly. When installing the assembly, the gap between the pulley and the magnetic coupling must be correct.
| The gap (1) between the pulley and the magnetic coupling must be 0.3 to 0.6 mm/0.012 to 0.024 in. when renewing the assembly. After running - in, the gap (1) should be 0.25 to 0.7 mm/0.010 to 0.027 in. | |||
