A good flare should have the
following characteristics:
- Inside surface is glossy and
smooth.
- Edge is smooth.
- Tapered sides are of uniform
length.
Bending
5. When bending the tube, be careful
not to crush it. To prevent crushing
of the tube, bend it gently and do
not bend the tube at a radius
curvature of less than 100 mm.
3. Remove the flare nut from the
unit and be sure to mount it on
the copper tube.
4. Make a flare at the end of copper
tube with a flare tool (Figure 14,15).
Outdoor Unit Installation
1. Install the unit mounting pads
(4 places) into the bottom channels
by tapping gently with a plastic or
rubber tipped hammer.
2. Set the unit on a strong surface
such as one made of concrete to
minimize shock and vibration and
to locate the unit securely.
3. Do not set the unit directly on the
ground.
Connecting the Unit with
Flaring Procedure.
Flaring (If piping is procured or cut at
the site).
1. Cut the copper tube to the
required length with a tube cutter.
It is recommended to cut approx.
30-50 cm. longer than the tubing
length you estimate.
2. Hold each pipe downward when
cutting and remove burrs at the
end of the copper tube with a tube
reamer or file. This process is
important and should be done
carefully to make a good flare
(Figure 12 and Figure 13).

Before After
6. If the copper tube is bent or pulled
too often, it will become stiff. Do
not bend the pipe more than three
times at one place.
Cautions before Connecting
Tubes Tightly
7. Be sure to apply a sealing cap
or water-proof tape to prevent
dust or water from getting into
the tubes before they are used.
8. Be sure to apply refrigerant
lubricant to the matching
surfaces of the flare and union
before connecting them together.
This is effective for reducing gas
leaks (Figure 16).

Connection
9. For proper connection, align the
union tube and flare tube straight
with each other, then screw in the
flare nut lightly at first to obtain a
smooth match (Figure 17).
When reaming, hold the tube end
downward and be sure that no
copper scraps fall into the tube.
10. Tighten the flare nut to the
specified tightening torque with
torque wrench and adjustable
wrench (Figure 18).
11. Repeat the process above for the
remaining line.
