Maintenance
Service intervals
Practically no maintenance is required. However, for an optimal operating safety and service life of the compressor we recommend to
carry out the necessary maintenance work regularly according to the specications of the manufacturer of the refrigerating plant.
5 I Maintenance
Function checks to be carried out once a year
Leak test of the plant
Checking the running noise of compressor
Checking pressures and temperatures of the plant
Checking the tensioner for orderly seating
Checking the V belts for tension and condition
Checking the oil level in the crankcase
Checking the xing screws for tightening
Checking the function of the ancillary units
Checking the electrical connections for clean, rmly xed contacts and the leads for chang points
Oil level check
After starting the compressor, the oil level has to be checked. For this:
The driving engine should be in the „High idle“ operating condition (elevated idling speed)
Compressor running time at least 10 min.
The plant should have reached the operating point
The oil level must be visible in the sight glass
Changing oil
In case of orderly manufactured and operated plants an oil change is in principle not absolutely necessary.
Yet, based on decades-long experience we recommend to carry out the following oil change and servicing.
- First oil change at the rst maintenance of the vehicle.
- After that, changing the oil every 5000 operating hours, but at the latest after 3 years.
At the same time the oil lter and the suction lter should be cleaned and the clamping ring with oil felt
from the shaft seal replaced.
Lubricants
The oil type lled as standard in the factory is marked on the name plate, and this should always be used, even in the case of maintenance
units. Alternative oil types can vary signicantly in quality due to additives or inferior raw materials by the manufacturer. Validation within the
compressors entire operating limits can not be guaranteed, if such alternative oil types are used. It is for this reason, that we only recommend
the use of oil from Bock! Bock assumes no liability for any damage arising from alternative oil types.
