[1] Read Before Servicing

1.  Check the type of refrigerant used in the system to be serviced.
Refrigerant Type
Multi air conditioner for building application REPLACE MULTI YJM-B series R410A
2.  Check the symptoms exhibited by the unit to be serviced.
Refer to this service handbook for symptoms relating to the refrigerant cycle.
3.  Thoroughly read the safety precautions at the beginning of this manual.
4.  Preparing necessary tools: Prepare a set of tools to be used exclusively with each type of refrigerant.
Refer to the manuals that came the tools for the correct usage.

5.  Verification of the connecting pipes: Verify the type of refrigerant used for the unit to be moved or replaced.
Use refrigerant piping made of phosphorus deoxidized copper. Keep the inner and outer surfaces of the new pipes and the end of the existing pipes clean and free of such contaminants assulfur, oxides, dust, dirt, shaving particles, oil, and moisture.
These types of contaminants inside the refrigerant pipes may cause the refrigerant oil to deteriorate.
6.  If there is a leak of gaseous refrigerant and the remaining refrigerant is exposed to an open flame, a poisonous gas hydrofluoric acid may form. Keep workplace well ventilated.
