IMPORTANT!
Please Read Before Starting

This air conditioning system meets strict safety and operat­ing standards. As the installer or service person, it is an
important part of your job to install or service the system so it
operates safely and efficiently.

For safe installation and trouble-free operation, you must:

●

Carefully read this instruction booklet before beginning.

●

Follow each installation or repair step exactly as shown.

●

Observe all local, state, and national electrical codes.

●

This product is intended for professional use.
Permission from the power supplier is required when
installing an outdoor unit that is connected to a 16 A
distribution network.

●

Pay close attention to all warning and caution notices
given in this manual.

This symbol refers to a hazard or
unsafe practice which can result
in severe personal injury or death.

This symbol refers to a hazard or
unsafe practice which can result
in personal injury or product or

If Necessary, Get Help

These instructions are all you need for most installation
sites and maintenance conditions. If you require help for a
special problem, contact our sales/service outlet or your
certified dealer for additional instructions.

In Case of Improper Installation

The manufacturer shall in no way be responsible for
improper installation or maintenance service, including fail­ure to follow the instructions in this document.

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 sys­tem. Carefully refer to the wiring diagram and these
instructions when wiring. Improper connections and inad­equate grounding can cause accidental injury or death.

• Ground the unit following local electrical codes.

• Connect all wiring tightly. Loose wiring may cause over­heating 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 con­nection.

• 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 speci­fied 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 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.

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 inter­locked with a gas leakage detector in the smallest
room where the density limit is exceeded, the vol­ume 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 condi­tioner, is safe, without the toxicity or combustibility of
ammonia, and is not restricted by laws imposed to pro­tect 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, how­ever, 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 com­pared 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 acci­dentally 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/m

)

The density limit of refrigerant which is used in multi air con­ditioners is 0.3 kg/m

3

(ISO 5149).

1. If there are 2 or more refrigerating systems in a sin­gle 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.

(1) When placing the unit inside the ceiling, deter-

mine the pitch of the suspension bolts using the
supplied full-scale installation diagram. (Fig. 2-4)
The size of the opening for the indoor unit can be
confirmed by attaching the full-scale installation
diagram beneath the unit. (Fig. 2-4)
Tubing and wiring must be laid inside the ceiling
when suspending the unit. If the ceiling is already
constructed, lay the tubing and wiring into posi­tion for connection to the unit before placing the
unit inside the ceiling.

(2) The length of suspension bolt must be appropri-

ate for a distance between the bottom of the bolt
and the bottom of the ceiling of 15 mm or more
as shown in Fig. 2-4.

(3) Thread the 2 hexagonal nuts (field supply) and

washers onto the 4 suspension bolts as shown in
Fig. 2-5.

Use 2 sets of nuts and washers (upper and
lower), so that the unit will not fall off the suspen­sion lugs.

(4) Remove the protective cardboard used to protect

the fan parts during transport.

(Fig. 2-8)

● If it is necessary to increase the height

of the drain pipe, the section directly
after the connection port can be raised
a maximum of 50 cm. Do not raise it
any higher than 50 cm, as this could
result in water leaks.
(Fig. 2-9)

● Do not install the pipe with an upward

gradient from the connection port. It
will cause the drain water to flow
backwards and leak when the unit is
stopped. (Fig. 2-10)

● Do not apply force to the piping on the

unit side when connecting the drain
pipe. The pipe should not be allowed
to hang unsupported from its connec­tion to the unit. Fasten the pipe to a
wall, frame, or other support as close
to the unit as possible. (Fig. 2-11)

smoothly. For this, prepare a bucket and wiping cloth
ready to catch and wipe up spilled water.

Do not supply power to the
unit until the tubing and
wiring to the outdoor unit
are completed.

(1) Take off the tube cover and through the opening,

slowly pour about 1,200 cc of water into the drain
pan to check drainage.

(2) Do Test Run to check the drainage after complet-

ing installation. When performing Test Run, be
sure to observe the Test Run procedure.

Be careful since the fan will

3. ELECTRICAL WIRING

3-1. 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 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 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 dam-

aged, it must be replaced by a repair shop
appointed by the manufacture, because special
purpose tools are required.

4. HOW TO PROCESS TUBING

The narrow tubing side is connected by a flare nut,
and the wide tubing side is connected by brazing.

4-1. 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 file. This process is important and
should be done carefully to make a good flare.
(Fig. 4-1)

When reaming, hold the tube end downward and be
sure that no copper scraps fall into the tube. (Fig. 4-2)

(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. 4-3)

(*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 connect­ing them together. This is effective for reducing
gas leaks. (Fig. 4-4)

(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. 4-5)

● 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.

4-2. Connecting Tubing Between Indoor and Out-

door Units

(1) Tightly connect the indoor-side refrigerant tubing

extended from the wall with the outdoor-side tub­ing.

(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. 4-6)
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 occu­pants.

● When removing or tightening the wide tube flare

nut, use 2 monkey wrenches together: one at the
wide tube flare nut and one at part A.(Fig. 4-7)

● 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 at right.

Fig. 4-4

Fig. 4-5

Fig. 4-6

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 narrow tube,

use a monkey wrench with a nominal handle length
of 200 mm.

4-3. Insulating the Refrigerant Tubing

Tubing Insulation

● Thermal insulation must be applied to all unit tub-

ing, 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.

Taping the flare nuts

Wind the white insulation tape around the flare nuts at
the wide tube connections. Then cover up the tubing
connections with the flare insulator, and fill the gap at
the union with the supplied black insulation tape.
Finally, fasten the insulator at both ends with the sup­plied vinyl clamps. (Fig. 4-10)

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.

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.

y

Fig. 4-9

Two tubes arranged together

If the exterior of the outdoor
unit valves has been finished
with a square duct covering,
make sure you allow suffi­cient space to use the valves
and to allow the panels to be
attached and removed.

● Do not use a spanner to tighten the valve stem

caps. Doing so may damage the valves.

● Depending on the installation conditions, applying

excessive torque may cause the nuts to crack.

Precautions for Packed Valve Operation

● If the packed valve is left for a long time with the

valve stem cap removed, refrigerant will leak from
the valve. Therefore, do not leave the valve stem
cap removed.

● Use a torque wrench to securely tighten the valve

stem cap.

● Valve stem cap tightening torque:.

4-4. 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 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. 4-12)

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.

4-5. 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. 4-13)

■ Tips for Energy Saving

NOTE

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 interrupted.

Avoid

Do

• 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.

• 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.

■ Suggerimenti per risparmiare energia

• Non ostruire la presa d’aria e l’uscita d’aria dell’unità. In caso di ostruzione,
l’unità non funziona correttamente e può subire dei danni.

• Non lasciar entrare la luce solare diretta nella stanza. A tale scopo utilizzare parasole,
tende o persiane. Se le pareti e il soffitto vengono riscaldati dal sole, il raffreddamento
della stanza richiede più tempo.

• Mantenete sempre pulito il filtro dell’aria (fare riferimento a “Cura e manutenzione”). Un
filtro ostruito compromette il rendimento dell’unità.

• Per evitare fughe d’aria condizionata, tenete chiuse finestre, porte ed altre aperture.

NOTA

Da evitare

Cose da fare

Mancanza di corrente durante il funzionamento dell’unità
