Refer to section 5 "Package contents" for details about the supplied connecting pipes.
・
When connecting pipes, make sure the service valves are completely closed.
・
Commercially available pipes often contain dust or debris. Always blow them clean with a dry inert gas.
・
Take care to prevent dust, water or other contaminants from entering the pipes during installation.
・
Reduce the number of bending portions as much as possible, and make the bending radius as big as possible.
・
Do not use any commercially available anti-oxidizing agents since they may cause pipe corrosion and degrading of
the refrigerant oil. Please contact Mitsubishi Electric for more details.
・
Make sure that the pipes are not in contact with each other, unit panels, or base plates.
