In case of twin, also be sure to flash the branching pipe.
Note]
Was not largely discolored oil or
a large quantity of remains discharged? (When the oil deteriorates, the color of the oil changes to muddy and black color.)
YES
nConnect 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 R410A.
nIn case that the gas pipe Ø 19 mm is used for the outdoor unit of SM803 (3 HP) or higher:
(Gas pipe size of our R410A model 3 to 5 HP is Ø 15.9 mm)
→ Turn the existing pipe switch on the cycle control P.C board of the outdoor unit to ON side.
At shipment from factory OFF → ON for existing pipe (Refer to the table below.) (Be sure to set the contents in the table below in order to restrict the refrigerating cycle pressure of the equipment in the pipe standard.)

Is there no scratch or dent on the existing pipes?
Is it possible to operate the existing air conditioner?
YES
* After the existing air conditioner operated in cooling mode for approx. 30 minutes or longer*, recover the refrigerant.
* For cooling the pipes and recovering of oil
• Refrigerant recovery: Pump down method
* Remove the existing air conditioner from the piping and carry out flashing (nitrogen pressure 0.5 Mpa) to remove the remains inside of the pipe.

Existing pipe: NO * Use a new pipes.

NO

Nitrogen gas pressure 0.5 Mpa

(If there is discharge of remains,

it is judged that there is a large quantity of remains.)

NO

Clean the pipes or use the new pipes.
