Connection of Refrigerant
Tubing

The principal concerns in
refrigeration tubing are:
• Uniform oil return to the

compressor.

• Pressure drops and their

effect on system capacity.

• Tubing routing and isolation

to avoid line breakage,
vibration and sound
transmission. Regarding this,
the interconnecting
refrigerant lines should be
simple and shorter as much
as possible.

There are two types of connections
available to interconnect refrigerant
tubes between indoor and outdoor
units.

- Flare connections for TTK5

(4th digit in model No.) series.

- Quick connections for TTK7

(4th digit in model No.) series.

Caution

Do not open the liquid and gas line
service valves until tubing
installation and system evacuation
is completed.

Connection the Unit with
Flaring Procedure

Flaring (If tubing 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 cm-50 cm
(12" to 20") longer than the
tubing length you estimate.

2. Hold each tube downward

when cutting, 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 2
and Figure 3).

When reaming, hold the tube
end downward and be sure
that no copper scraps fall into
the tube.

3. Remove the flare nut from the

service valve and be sure to
insert the flare nut onto tube.

4. Make a flare at the end of

copper tube with a flare tool
(Figure 4).

A good flare should have the
following characteristics:

- Inside surface is glossy and

smooth.

- Edge is smooth.
- Tapered sides are of uniform

length.
