When Connecting Refrigerant Tubing
WARNING
• When performing piping
work do not mix air except
for specified refrigerant
(R410A) in refrigeration
cycle. It causes capacity
down, and risk of
explosion and injury due
to high tension inside the
refrigerant cycle.
• Refrigerant gas leakage
may cause fire.
• Do not add or replace
refrigerant other than
specified type. It may
cause product damage,
burst and injury, etc.
• Ventilate the room well, in the event
that is refrigerant gas leaks during
the installation. Be careful not to allow
contact of the refrigerant gas with a
flame as this will cause the generation
of poisonous gas.
• Keep all tubing runs as short as
possible.
• Use the flare method for connecting
tubing.
• Apply refrigerant lubricant to the
matching surfaces of the flare and union
tubes before connecting them, then
tighten the nut with a torque wrench for
a leak-free connection.
• Check carefully for leaks before starting
the test run.
• Do not leak refrigerant while piping work
for an installation or re-installation, and
while repairing refrigeration parts.
Handle liquid refrigerant carefully as it
may cause frostbite.
When Servicing
• Turn the power OFF at the main
power box (mains) before opening
the unit to check or repair electrical
parts and wiring.
• Keep your fingers and clothing away
from any moving parts.
• Clean up the site after you finish,
remembering to check that no metal
scraps or bits of wiring have been left
inside the unit being serviced.
WARNING
• This product must not be
modified or disassembled
under any circumstances.
Modified or disassembled
unit may cause fire, electric
shock or injury.
• Do not clean inside the
indoor and outdoor units by
users. Engage authorized
dealer or specialist for
cleaning.
• In case of malfunction
of this appliance, do not
repair by yourself. Contact
the sales dealer or service
dealer for repair.
CAUTION
• Do not touch the air
inlet or the sharp
aluminum fins of the

injured.
•
Ventilate any enclosed
areas when installing or
testing the refrigeration
system. Escaped refrigerant
gas, on contact with fire
or heat, can produce
dangerously toxic gas.
• Confirm after installation
that no refrigerant gas is
leaking. If the gas comes
in contact with a burning
stove, gas water heater,
electric room heater or
other heat source, it can
cause the generation of
poisonous gas.
Others
WARNING
• Do not sit or step on
the unit, you may fall

Fig. 3-13
3-4. Checking the Drainage
After wiring and drain piping are completed, use the following
procedure to check that the water will drain smoothly. For this,
prepare a bucket and wiping cloth to catch and wipe up spilled
water.
(1) Connect power to the power terminal board (R, S
terminals) inside the electrical component box.
(2) Remove the tube cover and slowly pour about 1,200 cc
of water through the opening into the drain pan to check
drainage.
(3) Short-circuit the check pin (CHK) on the indoor control
circuit board and operate the drain pump. Check the water
flow through the transparent drain port and see if there is
any leakage.
CAUTION
Be careful since the fan will start when you short the pin on
the indoor control board.
(4) When the drainage check is complete, open the check pin
(CHK) and remount the insulator and drain cap onto the
drain inspection port.

5. HOW TO PROCESS TUBING
The liquid tubing side is connected by a flare nut, and the gas
tubing side is connected by brazing.
5-1. Connecting the Refrigerant Tubing
Use of the Flaring Method
Many of conventional split system air conditioners employ the
flaring method to connect refrigerant tubes that run between
indoor and outdoor units. In this method, the copper tubes are
flared at each end and connected with flare nuts.
Flaring Procedure with a Flare Tool
(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) Remove burrs at each end of the copper tubing with a
tube reamer or file. This process is important and should
be done carefully to make a good flare. Be sure to keep
any contaminants (moisture, dirt, metal filings, etc.) from
entering the tubing. (Figs. 5-1 and 5-2)
AfterBefore
Deburring
Copper
tubing
Reamer
Fig. 5-1 Fig. 5-2
NOTE
When reaming, hold the tube end downward and be sure that
no copper scraps fall into the tube. (Fig. 5-2)
(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 the copper tube with a flare tool.
(Fig. 5-3)
Flare nut
Copper
tubing
Flare tool
Fig. 5-3
NOTE
A good flare should have the following characteristics:
●inside surface is glossy and smooth
●edge is smooth
●tapered sides are of uniform length
Caution Before Connecting Tubes Tightly
(1) Apply a sealing cap or water-proof tape to prevent dust or
water from entering the tubes before they are used.
(2) Be sure to apply refrigerant lubricant (ether oil) to the
inside of the flare nut before making piping connections.
This is effective for reducing gas leaks. (Fig. 5-4)
Apply refrigerant lubricant.
Fig. 5-4
(3) For proper connection, align the union tube and flare tube
straight with each other, then screw on the flare nut lightly
at first to obtain a smooth match. (Fig. 5-5)
Flare nut
Union
Fig. 5-5
●Adjust the shape of the liquid tube using a tube bender at the
installation site and connect it to the liquid tubing side valve
using a flare.
Cautions During Brazing
●Replace air inside the tube with nitrogen gas to prevent
copper oxide film from forming during the brazing
process. (Oxygen, carbon dioxide and Freon are not
acceptable.)
●Do not allow the tubing to get too hot during brazing.
The nitrogen gas inside the tubing may overheat,
causing refrigerant system valves to become damaged.
Therefore allow the tubing to cool when brazing.
●Use a reducing valve for the nitrogen cylinder.
●Do not use agents intended to prevent the formation
of oxide film. These agents adversely affect the
refrigerant and refrigerant oil, and may cause damage or
malfunctions.
5-2. Connecting Tubing Between Indoor and
Outdoor Units
(1) Tightly connect the indoor-side refrigerant tubing extended
from the wall with the outdoor-side tubing.

Gas tubing (mm) ø12.7 ø15.88
Liquid tubing (mm) ø6.35 ø9.52
(2) To fasten the flare nuts, apply specified torque.
●When removing the flare nuts from the tubing connections,
or when tightening them after connecting the tubing, be sure
to use 2 adjustable wrenches or spanners. (Fig. 5-6)
If the flare nuts are over-tightened, the flare may be damaged,
which could result in refrigerant leakage and cause injury or
asphyxiation to room occupants.

●For the flare nuts at tubing connections, be sure to use the
flare nuts that were supplied with the unit, or else flare nuts
for R410A (type 2). The refrigerant tubing that is used must
be of the correct wall thickness as shown in the table below.
Tube diameter Tightening torque
(approximate) Tube thickness
ø6.35 (1/4") 14 – 18 N · m
{140 – 180 kgf · cm} 0.8 mm
ø9.52 (3/8") 34 – 42 N · m
{340 – 420 kgf · cm} 0.8 mm
ø12.7 (1/2") 49 – 61 N · m
{490 – 610 kgf · cm} 0.8 mm
ø15.88 (5/8") 68 – 82 N · m
{680 – 820 kgf · cm} 1.0 mm
Because the pressure is approximately 1.6 times higher than
conventional refrigerant pressure, the use of ordinary flare
nuts (type 1) or thin-walled tubes may result in tube rupture,
injury, or asphyxiation caused by refrigerant leakage.
●In order to prevent damage to the flare caused by over-
tightening of the flare nuts, use the table above as a guide
when tightening.
●When tightening the flare nut on the liquid tube, use an
adjustable wrench with a nominal handle length of 200 mm.
5-3. Insulating the Refrigerant Tubing
Tubing Insulation
●Thermal insulation must be applied to all units tubing,
including distribution joint (field supply).
* For gas tubing, the insulation material must be heat
resistant to 120°C or above. For other tubing, it must be
heat resistant to 80°C or above.
Insulation material thickness must be 10 mm or greater.
If the conditions inside the ceiling exceed DB 30°C and RH
70%, increase the thickness of the gas tubing insulation
material by 1 step.
Two tubes arranged together
Liquid tubing Gas tubing
Insulation
Fig. 5-7
CAUTION
If the exterior of the outdoor unit valves has been finished
with a square duct covering, make sure you allow sufficient
space to access the valves and to allow the panels to be
attached and removed.
Taping the flare nuts
Wind the white insulating tape around the flare nuts at the gas
tube connections. Then cover up the tubing connections with
the flare insulator, and fill the gap at the union with the supplied
black insulating tape. Finally, fasten the insulator at both ends
with the supplied vinyl clamps. (Fig. 5-8)

Insulation material
The material used for insulation must have good insulation
characteristics, be easy to use, be age resistant, and must not
easily absorb moisture.
CAUTION
After a tube has been insulated, never try to bend it into
a narrow curve because it can cause the tube to break or
crack.
Never grasp the drain or refrigerant connecting outlets
when moving the unit.
5-4. Taping the Tubes
(1) At this time, the refrigerant tubes (and electrical wiring
if local codes permit) should be taped together with
armoring tape in 1 bundle. To prevent condensation from
overflowing the drain pan, keep the drain hose separate
from the refrigerant tubing.
(2) Wrap the armoring tape from the bottom of the outdoor
unit to the top of the tubing where it enters the wall. As you
wrap the tubing, overlap half of each previous tape turn.
(3) Clamp the tubing bundle to the wall, using 1 clamp approx.
each meter. (Fig. 5-9)
Insulated tubes Drain hose
Clamp
Fig. 5-9
NOTE
Do not wind the armoring tape too tightly since this will
decrease the heat insulation effect. Also ensure that the
condensation drain hose splits away from the bundle and drips
clear of the unit and the tubing.

(3) Refer to Table 8-2 and Fig. 8-2 for details on the relationship between the value of item code “b0” and the external static pressure.
(4) When set in group control (connecting multiple indoor units with one wired remote controller), set each indoor unit to item code “b0”.
When amending the setting after selecting [ b. Manual setting] (due to airflow path changes, etc.), it is necessary to cancel [b.
Manual setting] (disconnect short-circuit connector). When [b. Manual setting] has not been cancelled, [c. Manual setting] and [d.
Auto airflow volume setting] will be activated if selected, but [b Manual setting] takes precedence when the power is switched back
on after power outages, etc.
(5) If this is not completed within 8 minutes, check the drive mode, air speed and air inlet temperature.
(6) When set in group control (connecting multiple indoor units with one wired remote controller), the test run operations display will
disappear once the external static pressure setting check or auto airflow volume control operation check have been completed for
the main unit. Decisions on sub-unit complete are not possible. The test run operation display will disappear after one hour even if
the external static pressure setting check or auto airflow volume control operation check have not been completed.
CAUTION
●Be sure to check that the external static pressure is within the range for use and then make the setting. Failure to observe
this may result in insufficient airflow or water leakages. Refer to Fig. 8-2 for the external static pressure setting range.
●There are cases in which automatic variable dampers and other mounted items may trigger the P12 alarm on systems that
modify the external static pressure when the auto airflow volume control operations or setting check operations are carried
out if high external static pressure is lowered. In this event, lower the dampers, etc., so that the external static pressure
reaches its lowest level, and then carry out the auto airflow volume control operations or setting check operations.
●Be sure to set the [External Static Pressure Setting] once again after amending the airflow path for the duct or air outlet
after setting the external static pressure.
●Set the air inlet temperature within the range for use. The auto airflow volume control will not function if the air inlet
temperature is over 45°C or not in the fan mode.
