(2) Perform the flaring work as shown below.
(3) Use specific flare nut attached with the unit.
(4) Verify that there are no scratches, burrs stuck to internal surfaces, or surface deformations at the flared
opening.
(5) Before tightening the flare nut, apply the (Field-Supplied) refrigerant oil in a thin layer over the flared
part. (Do not apply the oil on other areas.) Tighten the flare nut for the liquid pipe to the specified torque
with two spanners. Then, tighten the flare nut for the gas piping in the same way. After the tightening
work has been completed, check that no refrigerant leakage occurs.
NOTE:
Refrigerant oil is field-supplied.
[ Polyvinyl Ether Oil FVC68D (Idemitsu Lubricants America) ]
Apply Refrigerant Oil.
Do not apply
the refrigerant
oil to the
outside of the
flared opening.
