Note on Pipe Length
When connecting refrigerant piping, do not
let substances or gases other than the specified
refrigerant enter the unit. The presence of other gases or substances will lower the unit’s capacity,
and can cause abnormally high pressure in the refrigeration cycle. This can cause explosion and
injury.
Refrigerant Piping Connection
Ensure that the length of the refrigerant pipe, the number of bends, and the drop height
between the indoor and outdoor units meets the requirements shown in the following table :
