6-6-5. Final Installation Checks

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.

Note] In case of twin, also be sure to flash the branching pipe.

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

￿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 R410A.

∗In case that a gas pipe Ø19 mm or bigger is used for the outdoor unit of SM80 (3 HP) : (Our R410A model 3 to 6 HP gas pipe size is Ø15.9 mm)

See page 9-3-2.

∗(Airtight test), Vacuum dry, Refrigerant charge, Gas leak check

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.
