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 regulary
according to the specifications of the manufacturer of the refrigerating plant.
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 cranckcase
Checking the fixing screws for tightening
Checking the function of the ancillary units
Checking the electrical connections for clean, firmly fixed contacts and the leads for chafing points
Oil level check
Changing oil:
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.
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 first 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 filter and the suction filter should be cleaned and the oil collecting ring from
the shaft seal replaced.
