connected and the compressor works with the service valve open, the pipe inhales the air and it
makes the pressure inside of the refrigerant cycle abnormally high which may lead to explosion
and injury.
WARNING
Refrigerant pipe work
 The length of refrigerant pipe should be as short as possible and the height difference between an indoor
and outdoor unit should be minimized.
 Piping work must be done within allowable piping length, height difference, and the allowable length after
branching.

 After installing the pipes, calculate the total length of the pipe to check if additional refrigerant is needed.
When you need to charge the additional refrigerant, make sure to use R-410A refrigerant.
 Use clean refrigerant pipe and there shouldn’t be any harmful ion, oxide, dust, iron content or moisture
inside pipe.
