Weekly Brush or blow off the finned surface of the condensor.
Note (Full Feature units):
Regularly check that the condensate is discharged via the condensate outlet of the refrigerant dryer. The
amount depends on the operation conditions.
5.3 Lubrication of compressors
It is strongly recommended to use the Piston Fluid compressor oil to keep the compressor in excellent operating
condition.
Traditional lubricants cannot cope with the extreme conditions of piston compressors, resulting in a fast oil
degradation, overheating and potentially irreversible damage and high repair costs. Therefore, high
performing lubricants increase the equipment lifetime.
Considering the low oil content in piston compressors, often less than 2 liters, the economy of lesser quality
oils simply is not worth the risk.
Piston Fluid oil can be ordered in different quantities: a 1-liter can and 5-liter can.
5.4 Service kits
Service kits are available, offering the benefits of genuine Atlas Copco parts while keeping the maintenance
budget low. The kits comprise all parts needed for servicing. Consult the Parts list for the contents of all kits.
