When Installing…
Select an installation location which is
rigid and strong enough to support or
hold the unit, and select a location for
easy maintenance.
…In a Room
Properly insulate any tubing run inside a
room to prevent “sweating” that can cause
dripping and water damage to walls and
floors.
CAUTION Keep the fire alarm and
the air outlet at least
1.5 m away from the unit.
…In Moist or Uneven Locations
Use a raised concrete pad or concrete
blocks to provide a solid, level foundation
for the outdoor unit. This prevents water
damage and abnormal vibration.
…In an Area with High Winds
Securely anchor the outdoor unit down
with bolts and a metal frame. Provide a
suitable air baffle.
…In a Snowy Area (for Heat Pump-
type Systems)
Install the outdoor unit on a raised
platform that is higher than drifting snow.
Provide snow vents.

leakages.
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.
• If the refrigerant comes in contact
with a flame, it produces a toxic gas.
• Do not add or replace refrigerant
other than specified type. It may
cause product damage, burst and
injury, etc.
• Ventilate the room immediately, 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 toxic gas.
• Keep all tubing runs as short as
possible.
• 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.

4-1. General Precautions on Wiring
(1) Before wiring, confirm the rated voltage of the unit as
shown on its nameplate, then carry out the wiring closely
following the wiring diagram.
(2) Provide a power outlet to be used exclusively for each
unit, and a power supply disconnect and circuit breaker for
overcurrent protection should be provided in the exclusive
line.
(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-to-Water 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.
●
Use shielded wires for remote control wiring between
units and ground the shield on indoor unit’s side.
(9) If the power supply cable of this appliance is damaged,
it must be replaced by a repair shop appointed by the

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 which 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 the end of the copper tube with a tube
reamer or a similar tool. 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.
N OT E
When reaming, hold the tube end downward and be sure that
no copper scraps fall into the tube.
(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 copper tube with a flare tool.
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
Deburring
Before After

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
surface of a flare before making piping connections.
Pay attention not to attach the oil to the surface of screw.
This is effective for reducing gas leaks.
(3) 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.
●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.
(2) To fasten the flare nuts, apply specified torque.
Indoor Unit Tubing Connection ( 1, 2... n-1)
Indoor unit type 80 125
Gas tubing (mm) ø15.88
Liquid tubing (mm) ø9.52
●When removing the flare nuts from the tubing connections,
or when tightening them after connecting the tubing, be sure
to use a torque wrench and a spanner.
If the flare nuts are over-tightened, the flare may be
damaged, which could result refrigerant leakage and cause
in injury or asphyxiation to room occupants.

16
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.
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.
(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.
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.
●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.
Tube diameter Tightening torque,
approximate Tube thickness
ø9.52 mm
(3/8")
34 – 42 N · m
{340 – 420 NJI · cm} 0.8 mm
ø15.88mm
(5/8")
68 – 82 N · m
{680 – 820 NJI · 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 unit tubing,
including distribution joint (purchased separately).
* 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.
CAUTION
If the exterior of the outdoor unit valves has been finished
with square duct covering, make sure you allow sufficient
space to use the valves and to allow the panels to be
attached and removed.
N OT E
Gas Leakage Detector
Note that the gas leakage detector should be capable of
detecting the refrigerant R410A.
Air Purging
Refer to “AIR PURGING” in the separate Installation
Instructions for the outdoor unit in regard to air purging with a
vacuum pump (for test run) preparation.
Taping the flare nuts
Cover up the tubing connections with the supplied flare
insulator. Then fasten the insulator at both ends with the vinyl
clamps (field supply).
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.
Never grasp the drain or refrigerant connecting outlets
when moving the unit.
