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.

2. SELECTING THE INSTALLATION SITE
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
manual packed with the outdoor unit.
● allow room for mounting the remote controller about 1 m (3.3
ft.) off the floor, in an area that is not in direct sunlight nor in
the flow of cool air from the indoor unit.
● The elevation (Slim Low Static Ducted) between the bottom
unit and the floor surface should be at least 2.4 m (8 feet).
● If the elevation (Slim Low Static Ducted) between them is
less than 2.4 m (8 feet), install a filter or a protective device
(field supply) not to touch the electrical parts or fan with
hands.

• Connect the flange to the main unit with 10 - ø3.1 (Hole)
screws.
• Wrap the intake-side flange and duct connection area with
aluminum tape or something similar to prevent air escaping.
CAUTION
When attaching a duct to the intake-side, be sure to attach
an air filter inside the air passage on the intake-side. (Use
an air filter whose dust collecting efficiency is at least 50%
in a gravimetric technique.)
The included filter is not used when the intake duct is
attached.
Air outlet side
• Connect the duct according to the air outside of the outlet-
side flange.
• Wrap the outlet-side flange and the duct connection area
with aluminum tape or something similar to prevent air
escaping.
CAUTION
● Be sure to insulate the duct to prevent condensation from
forming. (Material: glass wool or polyethylene foam, 25 mm
thick)
● Use electric insulation between the duct and the wall when
using metal ducts to pass metal laths of the net or fence
shape or metal plating into wooden buildings.
● Be sure to explain about the way of maintaining and cleaning
local procurements (air filter, grille [both air outlet and suction
grille], etc.) to your customer.
3-5. Suspending the Indoor Unit
Depending on the ceiling type:
• Insert suspension bolts as shown in the diagram. (Fig. 3-8)

WARNING
It is important that you use extreme care in supporting
the indoor unit inside the ceiling. Ensure that the ceiling
is strong enough to support the weight of the unit. Before
hanging the unit, test the strength of each attached
suspension bolt.
(1) When placing the unit inside the ceiling, determine the pitch
of the suspension bolts referring to the dimensional data as
shown in Fig. 3-1.
Tubing must be laid and connected inside the ceiling when
suspending the unit. If the ceiling is already constructed,
lay the tubing into position for connection to the unit before
placing the unit inside the ceiling.
(2) Screw in the suspension bolts allowing them to protrude from
the ceiling as shown in Fig. 3-8. (Cut the ceiling material, if
necessary.)
(3) Thread the 3 hexagonal nuts and 2 washers (field supply)
onto each of the 4 suspension bolts as shown in Fig. 3-10
and 3-11. Use 1 nut and 1 washer for the upper part, and 2
nuts and 1 washer for the lower part, so that the unit will not
fall off the suspension lugs.

(4) Adjust the height of the unit.
(5) Check the unit is horizontally level.
CAUTION
● Make sure the unit is installed level using a level or a vinyl
hose filled with water. In using a vinyl hose instead of a level,
adjust the top surface of the unit to the surface of the water
at both ends of the vinyl hose and adjust the unit horizontally.
(One thing to watch out for in particular is if the unit is
installed so that the slope is not in the direction of the drain
piping, this might cause leaking.) (Fig. 3-12)

Earth Leakage Circuit Breaker (ELCB) must be an approved 10-16 A, having a contact separation in all poles.
(3) To prevent possible hazards from insulation failure, the unit must be grounded.
(4) Each wiring connection must be done in accordance with the wiring system diagram. Wrong wiring may cause the unit to
misoperate or become damaged.
(5) Do not allow wiring to touch the refrigerant tubing, compressor, or any moving parts of the fan.
(6) Unauthorized changes in the internal wiring can be very dangerous. The manufacturer will accept no responsibility for any damage
or misoperation that occurs as a result of such unauthorized changes.
(7) Regulations on wire diameters differ from locality to locality. For field wiring rules, please refer to your LOCAL ELECTRICAL
CODES before beginning.
You must ensure that installation complies with all relevant rules and regulations.
(8) To prevent malfunction of the air conditioner caused by electrical noise, care must be taken when wiring as follows:
● The remote control wiring and the inter-unit control wiring should be wired apart from the inter-unit power wiring.
● Use shielded wires for inter-unit control wiring between units and ground the shield on both sides.
(9) If the power supply cord of this appliance is damaged, it must be replaced by a repair shop designated by the manufacturer,
because special-purpose tools are required.

5. HOW TO PROCESS TUBING
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
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.
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 15 22 28 36 45 56
Gas tubing (mm) ø12.7
Liquid tubing (mm) ø6.35
(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.

ENGLISH
● 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
ø12.7 (1/2") 49 – 61 N · m
{490 – 610 kgf · cm} 0.8 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.

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)
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.
5-5. Finishing 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. (Fig. 5-10)
