3.Processing of refrigerant piping
(1) Pipe cutting
Cut the cooper pipe correctly with pipe cutter.
(2) Burrs removal
Completely remove all burrs from the cross section of the pipe.
Put the end of the copper pipe downward to prevent burrs from
dropping in the pipe.
(3) Putting nut on
Remove flare nuts attached to indoor and outdoor units, then put
them on burrs removed pipe.
(Not possible to put them on after flaring work).
Flare nut for pipe depends on the diameter of pipe.
(4) Flaring work
Perform flaring work with flaring tool as shown below.
(5) Check
Compare the flared work with the figure below.
If flare is noted to be defective, cut off the flared section and perform flaring work again.

4. Piping connection
(1) Confirm that the valve is closed.
(2) Connect the indoor unit and the outdoor unit with field-supplied
refrigerant piping. Suspend the refrigerant piping at certain points
and prevent the refrigerant piping from touching the weak part of
the building such as wall, ceiling, etc.
(If touched, abnormal sound may occur due to the vibration of the
piping. Pay special attention in case of short piping length.)
(3) Tighten the flare nut with two spanners as shown in the right
figure.
(4) Apply the refrigerant oil (field-supplied) thinly at the seat surface
of the flare nut and pipe before connecting and tightening.
And when tightening the flare nut, use two spanners.
(5) Outdoor refrigerant piping should connect with stop valve.
