1.4 Refrigerant Oil

To improve the reliability, the specified designed premium quality refrigerant oil is used in the compressor.
The refrigerant oil containing foam suppressor has the excellent thermal stability and high durability for
overload conditions.
1.4.1 Oil Type
Each type of refrigerant oil is specially designed for certain types of refrigerant and operating conditions, if
additional oil charge is added in the field, Only specified oil should be used.
