5 Refrigerant piping connection
5.1 Connection Instructions –
Refrigerant Piping
Step 1: Cut pipes
When preparing refrigerant pipes, take extra care
to cut and flare them properly. This will ensure
efficient operation and minimize the need for
future maintenance.
1. Measure the distance between the indoor and
outdoor units.
2. Using a pipe cutter, cut the pipe a little longer
than the measured distance.
3. Make sure that the pipe is cut at a perfect 90°
angle.

WARNING! Be extra careful not to
damage, dent, or deform the pipe
while cutting. This will drastically
reduce the heating efficiency of the
unit.
Step 2: Remove burrs
Burrs can affect the air-tight seal of refrigerant
piping connection. They must be completely
removed.
1. Hold the pipe at a downward angle to prevent
burrs from falling into the pipe.
2. Using a reamer or deburring tool, remove all
burrs from the cut section of the pipe.

Step 3: Flare pipe ends
Proper flaring is essential to achieve an airtight
seal.
1. After removing burrs from cut pipe, seal the
ends with PVC tape to prevent foreign materials
from entering the pipe.
2. Sheath the pipe with insulating material.
3. Place flare nuts on both ends of pipe. Make
sure they are facing in the right direction,
because you can’t put them on or change their
direction after flaring.

4. Remove PVC tape from ends of pipe when
ready to perform flaring work.
5. Clamp flare form on the end of the pipe.
The end of the pipe must extend beyond the
edge of the flare form in accordance with the
dimensions shown in the table below.

6. Place flaring tool onto the form.
7. Turn the handle of the flaring tool clockwise
until the pipe is fully flared.
8. Remove the flaring tool and flare form, then
inspect the end of the pipe for cracks and even
flaring.
Step 4: Connect pipes
When connecting refrigerant pipes, be careful not
to use excessive torque or to deform the piping
in any way. You should first connect the low-
pressure pipe, then the high-pressure pipe.

5.2 Instructions for connecting
piping to indoor unit
1. Align the center of the two pipes that you will
connect.

2. Tighten the flare nut as tightly as possible by
hand.
3. Using a spanner, grip the nut on the unit
tubing.
4. While firmly gripping the nut on the unit tubing,
use a torque wrench to tighten the flare nut
according to the torque values in the Torque
Requirements table below. Loosen the flaring
nut slightly, then tighten again.
