3.3 Oil change
1. Change oil periodically: Check lubrication oil every 10,000 hours of continuous running. For the first operation of the
compressor, it is recommended to change the oil and clean the external oil filter after 2,000 hours running. Check
whether the system is clean or not and then change oil every 20,000 hours or after 3 years’ continuous running while
the system operates in good condition.
2. Avoid clogging in oil filter with debris or swarf which may cause bearing failure. An optional oil pressure differential
switch is recommended. The switch will trip when the oil pressure differential between the primary and secondary sides
reaches the critical point and then the compressor will automatically shut down to prevent the bearings from damage
due to oil loss.
