When Connecting Refrigerant Tubing
WARNING
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
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.
WARNING
CAUTION
• Do not touch the air
inlet or the sharp
aluminum fins of the
outdoor unit. You may get
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
CAUTION
• Do not sit or step on
the unit, you may fall
down accidentally.
• Do not touch the air
inlet or the sharp
aluminum fins of the outdoor
unit. You may get injured.
• Do not stick any
object into the FAN
CASE.
You may be injured
and the unit may be
damaged.

2. SELECTING THE INSTALLATION SITE
2-1. Indoor Unit
AVOID:
● areas where leakage of flammable gas may be expected.
● places where large amounts of oil mist exist.
● direct sunlight.
● locations near heat sources which may affect the
performance of the unit.
● locations where external air may enter the room directly.
This may cause “condensation” on the air discharge ports,
causing them to spray or drip water.
● locations where the remote controller will be splashed with
water or affected by dampness or humidity.
● installing the remote controller behind curtains or furniture.
● locations where high-frequency emissions are generated.
DO:
● select an appropriate position from which every corner of the
room can be uniformly cooled.
● select a location where the ceiling is strong enough to
support the weight of the unit.
● select a location where tubing and drain pipe have the
shortest run to the outdoor unit.
● allow room for operation and maintenance as well as
unrestricted air flow around the unit.
● install the unit within the maximum elevation difference
above or below the outdoor unit and within a total tubing
length (L) from the outdoor unit as detailed in the Installation
Instructions packed with the outdoor unit.
● allow room for mounting the remote controller about 1 m off
the floor, in an area that is not in direct sunlight or in the flow

3-4. Duct for Fresh Air (Field supply)
There is a outside air intake duct connection port (cut out hole)
at the left-rear of the indoor unit for drawing in fresh air. If it is
necessary to draw in fresh air, remove the cover by opening
the hole and connecting the duct to the indoor unit through the
connection port. (Refer to Fig. 3-3)
3-5. Shaping the Tubing
● The positions of the refrigerant tubing connections are
shown in the figure below. (The tubing can be routed in
3 directions.) (Fig. 3-18)
* When routing the tubing out through the top or right sides,
cut out the cover of the top panel and cut notches in the side
panel (Refer to fig. 3-3).
Fig. 3-18
If the tubing is to be routed out
together, use a box cutter or
similar tool to cut out the part
of the cover indicated by
the marked area (Fig. 3-19),
to match the positions of the tubes.
Then draw out the tubing. Fig. 3-19
3-6. Installing the Drain Pipe
● Prepare hard PVC pipe for the drain and connect it to the
indoor unit drain pipe with the supplied hose band to prevent
water leaks.
● Measure the thickness of the wall from the inside to the
outside and cut PVC pipe at a slight angle to fit. Insert the
PVC pipe in the wall. (Fig. 3-21)

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

Reamer
Fig. 5-1 Fig. 5-2
N OT E
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
N OT E
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.
Indoor Unit Tubing Connection
Indoor unit type 36 45 56 73 106 140
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.
Insulation of the flare nuts
Attach the flare insulator (supplied) just like wrapping around
the flare nut (supplied). Match the both slits of flare insulators
for gas and liquid tubes facing upward. Tightly attach the end of
the flare insulators to the tube cradle without any space. Then
clamp the flare insulator with the clampers about 20 mm away
from both ends.

Tighten the clampers to prevent any condensation that may
occur as the copper tubing is exposed.
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)

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.
N OT E
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.

mist exist at restaurants.)
● Cleaning is necessary because unit inside (heat exchanger) is dirty.
Consult your dealer as technical engineering is required.
● During defrost operation
Fan is rotating for a while even though operation
stops.
● Fan rotating makes operation smoothly.
● Fan may sometimes rotate because of drying heat exchanger due to
settings.
Wind-direction changes while operating.
Wind-direction setting cannot be made.
Wind-direction cannot be changed.
● When air discharge temperature is low or during defrost operation,
horizontal wind flow is made automatically.
● Flap position is occasionally set up individually.
When wind-direction is changed, flap operates
several times and stops at designated position.
When wind-direction is changed, flap operates after searching for
standard position.
Dust Dust accumulation inside indoor unit is discharged.
Poor cooling or heating
performance
The indoor unit is initially designed to control the indoor temperature
detected by the built-in room sensor inside the indoor unit.
Due to indoor unit installation position, however, the buit-in sensor may
occasionally sense temperature improperly; for example, temperature
difference between the ceiling and floor, lighting apparatus, electric fan,
windows or waist-high partition walls, etc.
In this case, the unit does not operate properly at the desired temperature.
You may change the use of the temperature sensor inside the indoor unit
to that of the remote controller.
Then the desired room temperature can be controlled properly.
For details, consult your dealer.

controller again.
Operation button is turned off.
● Switch on power if breaker is turned off.
● If breaker has been tripped, consult your dealer
without turning it on.
Fuse blow out. If blown out, consult your dealer.
Poor cooling or heating
performance
Air intake or air discharge port of indoor
and outdoor units is clogged with dust or
obstacles.
Remove dust or obstruction.
Wind speed switch is set to “Low”. Change to “High” or “Strong”.
Improper temperature settings
Refer to “ ■ Tips for Energy Saving”.
Room is exposed to direct sunlight in
cooling mode.
Doors and /or windows are open.
Air filter is clogged. Refer to “ ■ Care and Cleaning”.
Too much heat sources in room in
cooling mode. Use minimum heat sources and in a short time.
Too many people in room in cooling
mode.
Reduce temperature settings or change to “High” or
“Strong”.
If your air conditioner still does not work properly although you checked the points as described above, first stop the operation
and turn off the power switch. Then contact your dealer and report the serial number and symptom. Never repair your air
conditioner by yourself since it is very dangerous for you to do so. You also report if the inspection mark and the letters E, F, H,
L, P in combination with the numbers appear on the LCD of the remote controller.
■ Tips for Energy Saving
Avoid
● Do not block the air intake and outlet of the unit. If either is obstructed, the unit will not work well, and may be damaged.
● Do not let direct sunlight into the room. Use sunshades, blinds or curtains. If the walls and ceiling of the room are warmed by the
sun, it will take longer to cool the room.
Do
● Always try to keep the air filter clean. (Refer to “Care and Cleaning”.) A clogged filter will impair the performance of the unit.
● To prevent conditioned air from escaping, keep windows, doors and any other openings closed.
