SPECIAL PRECAUTIONS
When Wiring
ELECTRICAL SHOCK CAN CAUSE
SEVERE PERSONAL INJURY OR DEATH.
ONLY A QUALIFIED, EXPERIENCED
ELECTRICIAN SHOULD ATTEMPT TO
WIRE THIS SYSTEM.
• Do not supply power to the unit until all wiring and tubing
are completed or reconnected and checked.
• Highly dangerous electrical voltages are used in this sys-
tem. Carefully refer to the wiring diagram and these
instructions when wiring. Improper connections and inad-
equate grounding can cause accidental injury or death.
• Ground the unit following local electrical codes.
• Connect all wiring tightly. Loose wiring may cause over-
heating at connection points and a possible fire hazard.
When Transporting
Be careful when picking up and moving the indoor and outdoor
units. Get a partner to help, and bend your knees when lifting
to reduce strain on your back. Sharp edges or thin aluminum
fins on the air conditioner can cut your fingers.
When Installing…
…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.
…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.
When Connecting Refrigerant Tubing
• 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 con-
nection.
• Check carefully for leaks before starting the test run.
Depending on the system type, liquid and gas lines may
be either narrow or wide. Therefore, to avoid confusion
the refrigerant tubing for your particular model is speci-
fied as either “narrow” or “wide” than as “liquid” or “gas.”
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.
• 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 leak-
ing. 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.

2. The standards for minimum room volume are as
follows.
(1) No partition (shaded portion)
(2) When there is an effective opening with the adja-
cent room for ventilation of leaking refrigerant gas
(opening without a door, or an opening 0.15% or
larger than the respective floor spaces at the top
or bottom of the door).
(3) If an indoor unit is installed in each partitioned
room and the refrigerant tubing is interconnected,
the smallest room of course becomes the object.
But when mechanical ventilation is installed inter-
locked with a gas leakage detector in the smallest
room where the density limit is exceeded, the vol-
ume of the next smallest room becomes the object.
3. The minimum indoor floor space compared with the
amount of refrigerant is roughly as follows: (When
the ceiling is 2.7 m high)
Check of Density Limit
The room in which the air conditioner is to be
installed requires a design that in the event of
refrigerant gas leaking out, its density will not
exceed a set limit.
The refrigerant (R410A), which is used in the air condi-
tioner, is safe, without the toxicity or combustibility of
ammonia, and is not restricted by laws imposed to pro-
tect the ozone layer. However, since it contains more
than air, it poses the risk of suffocation if its density
should rise excessively. Suffocation from leakage of
refrigerant is almost non-existent. With the recent
increase in the number of high density buildings, how-
ever, the installation of multi air conditioner systems is
on the increase because of the need for effective use
of floor space, individual control, energy conservation
by curtailing heat and carrying power, etc.
Most importantly, the multi air conditioner system is
able to replenish a large amount of refrigerant com-
pared to conventional individual air conditioners. If a
single unit of the multi air conditioner system is to be
installed in a small room, select a suitable model and
installation procedure so that if the refrigerant acci-
dentally leaks out, its density does not reach the limit
(and in the event of an emergency, measures can be
made before injury can occur).
In a room where the density may exceed the limit,
create an opening with adjacent rooms, or install
mechanical ventilation combined with a gas leak
detection device. The density is as given below.
Total amount of refrigerant (kg)
Min. volume of the indoor unit installed room (m3)
≤Density limit (kg/m3)
The density limit of refrigerant which is used in multi air con-
ditioners is 0.44 kg/m3(ISO 5149).
1. If there are 2 or more refrigerating systems in a sin-
gle refrigerating device, the amount of refrigerant
should be as charged in each independent device.
For the amount of charge in this example:
The possible amount of leaked refrigerant gas in rooms
A, B and C is 10 kg.
The possible amount of leaked refrigerant gas in rooms
D, E and F is 15 kg.

5. ELECTRICAL WIRING
5-1. 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 cir-
cuit breaker for overcurrent protection should be
provided in the exclusive line.
(3) To prevent possible hazards from insulation fail-
ure, the unit must be grounded.
(4) Each wiring connection must be done in accor-
dance 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 begin-
ning.
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 dam-
aged, it must be replaced by a repair shop
appointed by the manufacture, because special
purpose tools are required.

A fire hazard may also
exist. Therefore, ensure
that all wiring is tightly
connected.
When connecting each power wire to the terminal, fol-
low the instructions on “How to connect wiring to the
terminal”and fasten the wire securely with the fixing
screw of the terminal plate.
How to connect wiring to the terminal
■For stranded wiring
(1) Cut the wire end with cutting pliers, then strip the
insulation to expose the stranded wiring about 10
mm and tightly twist the wire ends. (Fig. 5-5)
(2) Using a Phillips head screwdriver, remove the ter-
minal screw(s) on the terminal plate.
(3) Using a ring connector fastener or pliers, securely
clamp each stripped wire end with a ring pressure
terminal.
(4) Place the ring pressure terminal, and replace and
tighten the removed terminal screw using a screw-
driver. (Fig. 5-6)

6. HOW TO PROCESS TUBING
The narrow tubing side is connected by a flare nut,
and the wide tubing side is connected by brazing.
6-1. 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 esti-
mate.
(2) Remove burrs at the end of the copper tube with a
tube reamer or file. This process is important and
should be done carefully to make a good flare.
(Fig. 6-1)
When reaming, hold the tube end downward and be
sure that no copper scraps fall into the tube. (Fig. 6-2)
(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 copper tube with a
flare tool.* (Fig. 6-3)
(*Use “RIGID®”or equivalent.)
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 to the match-
ing surfaces of the flare and union before connect-
ing them together. This is effective for reducing
gas leaks. (Fig. 6-4)
(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. (Fig. 6-5)
●Adjust the shape of the narrow tube (liquid tube)
using a tube bender at the installation site and
connect it to the narrow tubing side (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 for-
mation of oxide film. These agents adversely
affect the refrigerant and refrigerant oil, and
may cause damage or malfunctions.
6-2. Connecting Tubing Between Indoor and Out-
door Units
(1) Tightly connect the indoor-side refrigerant tubing
extended from the wall with the outdoor-side tub-
ing.
(2) To fasten the flare nuts, apply specified torque as
at right:
●When removing the flare nuts from the tubing con-
nections, or when tightening them after connecting
the tubing, be sure to use 2 monkey wrenches or
spanners as shown. (Fig. 6-6)
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 occu-
pants.
●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 refriger-
ant tubing that is used must be of the correct wall
thickness as shown in the table at right.

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 asphyxi-
ation 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 narrow tube,
use a monkey wrench with a nominal handle length
of 200 mm.

6-3. Insulating the Refrigerant Tubing
Tubing Insulation
●Thermal insulation must be applied to all unit tub-
ing, including distribution joint (purchased sepa-
rately).
* 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.
Taping the flare nuts
Wind the insulation tape around the flare nuts at the
wide tube connections. Then cover up the tubing con-
nections with the flare insulator, and fill the gap at the
union with the insulation tape. Finally, fasten the insu-
lator at both ends with the vinyl clamps. (Fig. 6-8)
Insulation material
The material used for insulation must have good insu-
lation characteristics, be easy to use, be age resis-
tant, and must not easily absorb moisture.
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.
CAUTION
CAUTION
Never grasp the drain or refrigerant connecting
outlets when moving the unit.

6-4. 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 pre-
vent the 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. 6-10)
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 pre-
vent rain and draft from entering. (Fig. 6-11)

Care and Cleaning
1. For safety, be sure to turn the air conditioner off and also to
disconnect the power before cleaning.
2. Do not pour water on the indoor unit to clean it. This will damage the
internal components and cause an electric shock hazard.
Air intake and outlet side
(Indoor unit)
Clean the air intake and outlet side of the indoor unit with a vacuum cleaner
brush, or wipe them with a clean, soft cloth.
If these parts are stained, use a clean cloth moistened with a mild liquid
detergent. When cleaning the air outlet side, be careful not to force the vanes
out of place.
1. Never use solvents or harsh chemicals when cleaning the indoor
unit. Do not wipe plastic parts using very hot water.
2. Some metal edges and the fins are sharp and may cause injury if
handled improperly; be especially careful when you clean these
parts.
3. The internal coil and other components of the outdoor unit must be
cleaned every year. Consult your dealer or service center.
Air filter The air filter collects dust and other particles from the air and should be
cleaned once every six months or when
the filter indication ()on thedisplay of theremotecontrol unit (wired type)shows
that the filter needs cleaning.Ifthe filter getsblocked, the efficiency of the air
conditioner drops greatly.

Troubleshooting
If your air conditioner does not work properly, first check the following points before requesting service. If it still does
not work properly, contact your dealer or a service center.
Tips for Energy Saving
Trouble Possible Cause Remedy
Air conditioner does not run at all. 1. Power failure. 1. After a power outage, press ON/
OFF operation button on the
wired remote control unit.
2. Leakage circuit breaker has
tripped.
2. Contact service center.
3. Line voltage is too low. 3. Consult your electrician or dealer.
4. Operation button is turned off. 4. Press the button again.
5. The wired remote control unit or
heat pump is malfunctioning.
(The inspection mark and the
letters E, F, H, L, P in
combination with numbers
appear on the LCD of the wired
remote control unit.)
5. Consult your dealer.
Compressor runs but soon stops. 1. Obstruction in front of condenser
coil.
1. Remove obstruction.
Poor cooling (or heating)
performance.
1. Dirty or clogged air filter. 1. Clean air filter to improve the
airflow.
2. Heat source or many people in
room.
2. Eliminate heat source if possible.
3. Doors and/or windows are open. 3. Shut them to keep the heat (or
cold) out.
4. Obstacle near air intake or air
discharge port.
4. Remove it to ensure good airflow.
5. Thermostat is set too high for
cooling (or too low for heating).
5. Set the temperature lower (or
higher).
6. (Defrosting system does not work.) 6. (Consult your dealer.)
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.
Should the power fail while the unit is running
If the power supply for this unit is temporarily cut off, the unit will automatically
resume operation once power is restored using the same settings before the
power was cut off.
