Caution:
1
）
Please refer to the table above to select the suitable lubricant and refrigerant and
its operation range need to be taken into consideration as well.
2
）
Hanbell strongly recommends do not use the lubricant which isn’t certified by
Hanbell since it may damage the compressor seriously.
3
）
This specification table is for LT series compressors only.
4
）
The oil temperature at the point when the compressor starts is suggested to be 5K
higher than the corresponding saturation temperature of the oil separator in order
to avoid too much oil containing in the refrigerant which may affect the lubricant.
5
）
After compressor stops, please turn on the oil heater of the external oil separator.
If the compressor shuts down for a long time, please turn off the oil heater. Please
heat the lubricant for more than 2 hours before next start up.

Be sure to make the system clean and no welding spatter and other impurities
before lubricant filling
2
）
In order to ensure that the system is dry enough, it should be dehumidified before
filling. It is advisable to fill the system with dry nitrogen first and then vacuum the
system. The vacuum time should be as long as possible. It is strongly
recommended to repeat the above steps several times to minimize the water
contained in the system.
