COMPRESSOR INSTALLATION & START-UP GUIDE
REVISION M
1.1. Reserve enough space for connection and installation of the electrical terminal box, service/stop valves and
solenoid valves on the compressor.
1.2. Consider the compressors’ future overhaul when determining space requirements. All compressors’ outside
parts and electrical controller lines and terminal connections etc should be spaced for easy dismantle and re-
assemble.
Recommended Maintenance Schedule
Found in back of this manual
Note:
This maintenance schedule is only to be used as a rough estimate, not a basis for any claim. The most appropriate
running period for each checkpoint is varied with operating condition (air-cooled or water-cooled), refrigerant, and
lubricant (synthetic or mineral).
Replacement of piston rings and bearings should be performed by Hanbell authorized technicians. When counts of
piston loading and unloading motion are higher than 10,000 times, piston rings should be replaced immediately.
Oil change
1. Break in period
- it is recommended to change oil and clean oil filter after running
2,00 hours
.
2.
Check the lubrication
oil condition every 10,000 hours
of continuous running. It’s a good idea to do an
oil analysis
each 10,000 hours
of continuous running.
3.
Check the system and change the oil every 20,000 hours or after 3 years of continuous running
4.
Avoid debris or clogging oil filter, this may cause bearings failure. An optional oil pressure differential switch is
recommended to be installed. The switch will trip when the oil pressure differential reaches the critical point between the
primary and secondary sides. The compressor will automatically shut down to prevent the bearings from getting damaged
due to the lack of lubricating oil.
