10.2 Refrigerant Tubing
Deburring
10.2.1 Use of The Flaring Method
Before
After
Many of the conventional split system air
conditioners employ the flaring method to
connect refrigerant tubes which run between
indoor and outdoor units. In this method, the
copper tubes are flared at each end and
connected with flares nuts.
10.2.2 Flaring Procedure With A Flare
Tool
•
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.
Fig.25
Copper
tubing
•
Remove burrs at the end of the copper
tube with a reamer or file. This procedure
is important and should be done carefully
to make a good flare. (Fig.25)
Reamer
When reaming, hold the tube end
downward and be sure that no
copper scraps fall into the tube.
(Fig.26)
NOTE
Fig.26
•
•
Remove the flare nut from the unit and be
sure to mount it on the copper tube.
Make a flare at the end of copper tube with
a flare tool.* (Fig.27)

(*Use "GRID" or equivalent.)
NOTE
A good flare should have the
following charactcteristics:
- inside surface is glossy and
smooth.
Flare tool

- edge is smooth.
- tapered sides are of uniform
length.
10.2.3 Caution Before Connecting Tubes
Tightly
Apply refrigerant
Iubricant here and here
•
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.
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. (Fig.28)
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. (Fig.29)

10.2.5 Insulation of Refrigerant Tubing
IMPORTANT
Insulation
To prevent heat loss and wet floors due to dripping
of condensation, both tubes must be well
insulated with a proper insulation material. The
thickness of the insulation should be a min. 8 mm.
(Fig. 31, 32)

CAUTION
After a tube has been insulated, never try to bend
it into a narrow curve, as this may cause to break
or crack.
Fig.32
10.2.6 Taping the Tubes
•
At this time, the 2 refrigerant tubes (and
electrical wire if codes permit) should be taped
together with armoring tape. The drain hose
may also be taped together as 1 bundle with
the tubing.
Clamp
•
Wrap the armoring tape from the bottom of the
outdoor to the top of tubing where it enters the
wall. As you wrap the tubing, overlap half of
each previous tape turn. (Fig. 33)
Insulated tubes
Clamp tubing bundle to wall, using 1 clamp
approx. every 120cm.
•
Do not wind the armoring tape too
NOTE

tightly, since this will decrease the
heat insulation effect. Also, be sure
the condensation drain hose splits
away from the bundle and drips
clear of the unit and the tubing.
Apply putty here
10.2.7 Finish the Installation
After finishing insulating and taping over the
tubing, use sealing putty to seal off the hole in
the wall to prevent rain and draft from entering.

10.3 Air Purging
Air and moisture remaining in the refrigerant
system have undersirable effects as indicated
below. Therefore, they must be purged
completely.
Indoor unit
• Pressure in the system rises
• Operating current rises
• Cooling (or heating) efficiency drops
• Moisture in the air may freeze and block
capillary tubing.
Outdoor unit
• Water may lead to corrosion of parts in the
refrigerant system.
AIR PURGING WITH A VACUUM PUMP
(FOR TEST RUN)
1. Check that each tube (both narrow and wide
tubes) between the indoor and outdoor units
have been properly connected and all wiring
for the test run has been completed. Noted
that both narrow and wide tube service valves
on the outdoor unit are kept closed at this
stage.

9. Turn the narrow tube service valve stem
counter- clockwise to fully open the valve.
10. Loosen the vacuum hose connected to the
wide tube service port slightly to release the
pressure. Then, remove the hose.
CAUTION
This may cause the refrigerant gas
to leak. In order to avoid this, take
off the hose quickly.
11. Fasten the valve cap on the wide tube
service port securely with an adjustable
wrench or box wrench. Next, mount the
valve cap on the service valve and
tightened it to 200 kg-cm with a torque
wrench. This process is very important to
prevent gas leaking from the system.
15. Wipe off the soap on the tubing.
12. Test run the air conditioner. (See page 34)
This completes air purging with a
vacuum pump and the air conditioner is
ready for actual operation.
13. While the air conditioner is running, apply
liquid soap to check for any gas leaks
around the service valves or caps.
14. If there is no leakage, stop the air
conditioner.
