NO
Is it possible to operate the existing air conditioner?
YES
After the existing air conditioner is operated in
cooling mode for approx. 30 minutes or longer,*
recover the refrigerant.
Refer to "13 Refrigerant recovery"
For cleaning the pipes and recovering oil
Refrigerant recovery: Pump down method
Remove the existing air conditioner from the piping
and carry out flushing (nitrogen pressure 0.5 MPa)
to remove any remains inside of the pipe.
Was largely discolored oil or a large quantity
of remains discharged? (When the oil deteriorates,
the color of the oil changes to a muddy or
black color.)
NO
Connect the indoor / outdoor units to the existing pipe.
Use a flare nut attached to the main unit for the
indoor / outdoor units. (Do not use the flare nut of
the existing pipe.)
Re-machine the flare machining size to size for R32.
In case that the gas pipe Ø19 mm is used for the
outdoor unit of GV110 (4 HP) or higher : (Our R32
model 4 to 6 HP gas pipe size is Ø15.9 mm)
