1 Precautions for safety

The manufacturer shall not assume any liability for the damage
caused by not observing the description of this manual.

WARNING

General

• Before starting to install the air conditioner, read through the
Installation Manual carefully, and follow its instructions to install
the air conditioner. Otherwise, falling down of the unit may occur,
or the unit may cause noise, vibration or water leakage.

• Only a qualified installer(*1) or qualified service person(*1) is
allowed to do installation work. If installation is carried out by
an unqualified individual, a fire, electric shocks, injury, water
leakage, noise and/or vibration may result.

• If using separately sold products, make sure to use Toshiba
specified products only. Using unspecified products may cause
fire, electric shock, water leak or other failure.

• Do not use any refrigerant different from the one specified for
complement or replacement.

Otherwise, abnormally high pressure may be generated in the

refrigeration cycle, which may result in a failure or explosion of
the product or an injury to your body.

• Before opening the service panel of the outdoor unit, set the
circuit breaker to the OFF position. Failure to set the circuit
breaker to the OFF position may result in electric shocks through
contact with the interior parts. Only a qualified installer(*1) or
qualified service person(*1) is allowed to remove the service
panel of the outdoor unit and do the work required.

• Before carrying out the installation, maintenance, repair or
removal work, be sure to set the circuit breakers for both the
indoor and outdoor units to the OFF position. Otherwise, electric
shock may result.

• Place a “Work in progress” sign near the circuit breaker while the
installation, maintenance, repair or removal work is being carried
out. There is a danger of electric shocks if the circuit breaker is
set to ON by mistake.

• Only a qualified installer(*1) or qualified service person(*1) is
allowed to undertake work at heights using a stand of 50 cm or
more or to remove the intake grille of the indoor unit to undertake
work.

• Wear protective gloves and safety work clothing during
installation, servicing and removal.

• Do not touch the aluminium fin of the outdoor unit. You may
injure yourself if you do so. If the fin must be touched for some
reason, first put on protective gloves and safety work clothing,
and then proceed.

• Do not climb onto or place objects on top of the outdoor unit. You
may fall or the objects may fall off of the outdoor unit and result
in injury.

• When working at height, put a sign in place so that no-one will
approach the work location before proceeding with the work.
Parts or other objects may fall from above, possibly injuring a
person below. Also, be sure that workers put on helmets.

• When cleaning the filter or other parts of the outdoor unit, set
the circuit breaker to OFF without fail, and place a “Work in
progress” sign near the circuit breaker before proceeding with
the work.

• The refrigerant used by this air conditioner is the R410A.

• You shall ensure that the air conditioner is transported in stable
condition. If you find any part of the product broken, contact your
dealer.

• Do not disassemble, modify or move the product yourself. Doing
so may cause fire, electric shock, injury or water leaks.

6-EN5-EN

• This appliance is intended to be used by expert or trained users

AMP Air Conditioning

www.ampair.co.uk | [e-mail]

in shops, in light industry, or for commercial use by lay persons.

• We do not take any responsibility on the local design.

Selection of installation location

• If you install the unit in a small room, take appropriate measures
to prevent the refrigerant from exceeding the limit concentration
even if it leaks. Consult the dealer from whom you purchased the
air conditioner when you implement the measures. Accumulation
of highly concentrated refrigerant may cause an oxygen
deficiency accident.

• Do not install in a location where flammable gas may leaks are
possible. If the gas should leak and accumulate around the unit,
it may ignite and cause a fire.

• When transporting the air conditioner, wear shoes with protective
toe caps, protective gloves and other protective clothing.

• When transporting the air conditioner, do not take hold of the
bands around the packing carton. You may injure yourself if the
bands should break.

• Other than floor standing and console types, install the indoor
unit at least 2.5 m above the floor level since otherwise the users
may injure themselves or receive electric shocks if they poke
their fingers or other objects into the indoor unit while the air
conditioner is running.

• Do not place any combustion appliance in a place where it is
directly exposed to the wind of air conditioner, otherwise it may
cause imperfect combustion.

• Do not install outdoor units where the operation sound may
cause a disturbance. (Especially at the boundary line with a
neighbour, install the air conditioner while considering the noise.)

Installation

• Follow the instructions in the Installation Manual to install the air
conditioner. Failure to follow these instructions may cause the
product to fall down or topple over or give rise to noise, vibration,
water leakage or other failure.

• The designated bolts (M12) and nuts (M12) for securing the
outdoor unit must be used when installing the unit.

• Install the outdoor unit property in a location that is durable
enough to support the weight of the outdoor unit. Insufficient
durability may cause the outdoor unit to fall, which may result in
injury.

• Install the unit in the prescribed manner for protection against
strong wind and earthquake. Incorrect installation may result in
the unit falling down, or other accidents.

• Be sure to fix the screws back which have been removed for
installation or other purposes.

Refrigerant piping

• Install the refrigerant pipe securely during the installation
work before operating the air conditioner. If the compressor
is operated with the valve open and without refrigerant pipe,
the compressor sucks air and the refrigeration cycles is over
pressurized, which may cause a injury.

• Tighten the flare nut with a torque wrench in the specified
manner. Excessive tighten of the flare nut may cause a crack in
the flare nut after a long period, which may result in refrigerant
leakage.

• Ventilate the air if the refrigerant gas leaks during installation.
If the leaked refrigerant gas comes into contact with fire, toxic
gas may be produced.

• After the installation work, confirm that refrigerant gas does
not leak. If refrigerant gas leaks into the room and flows near
a fire source, such as a cooking range, noxious gas may be
generated.

• When the air conditioner has been installed or relocated,
follow the instructions in the Installation Manual and purge
the air completely so that no gases other than the refrigerant
will be mixed in the refrigerating cycle. Failure to purge the air
completely may cause the air conditioner to malfunction.

• Nitrogen gas must be used for the airtight test.

• The charge hose must be connected in such a way that it is not
slack.

• If refrigerant gas has leaked during the installation work, ventilate
the room immediately. If the leaked refrigerant gas comes in
contact with fire, noxious gas may be generated.

Electrical wiring

• Only a qualified installer(*1) or qualified service person(*1) is
allowed to carry out the electrical work of the air conditioner.

Under no circumstances must this work be done by an

unqualified individual since failure to carry out the work properly
may result in electric shocks and/or electrical leaks.

• When connecting the electrical wires, repairing the electrical
parts or undertaking other electrical jobs, wear gloves to provide
protection for electricians and from heat, insulating shoes and
clothing to provide protection from electric shocks. Failure to
wear this protective gear may result in electric shocks.

• When executing address setting, test run, or troubleshooting
through the checking window on the electrical control box, put on
insulated heat-proof gloves, insulated shoes and other clothing
to provide protection from electric shock. Otherwise you may
receive an electric shock.

• Use wiring that meets the specifications in the Installation
Manual and the stipulations in the local regulations and laws.
Use of wiring which does not meet the specifications may give
rise to electric shocks, electrical leakage, smoking and/or a fire.

• Check that the product is properly earthed. (grounding work)

Incomplete earthing may cause electric shock.

• Do not connect the earth line to a gas pipe, water pipe, lightning
conductor, or a telephone earth line.

• After completing the repair or relocation work, check that the
ground wires are connected properly.

• Install a circuit breaker that meets the specifications in the
installation manual and the stipulations in the local regulations
and laws.

• Install the circuit breaker where it can be easily accessed by the
agent.

• When installing the circuit breaker outdoors, install one which is
designed to be used outdoors.

• Under no circumstances must the power cable be extended.
Connection trouble in the places where the cable is extended
may give rise to smoking and/or a fire.

• Electrical wiring work shall be conducted according to law and
regulation in the community and installation manual.

Failure to do so may result in electrocution or short circuit.

• Do not supply power from the power terminal block equipped on
the outdoor unit to another outdoor unit. Capacity overflow may
occur on the terminal block and may result in fire.

• When carrying out electric connection, use the wire specified in
the Installation Manual and connect and fix the wires securely to
prevent them applying external force to the terminals. Improper
connection or fixing may result in fire.

• Before operating the air conditioner after having completed the
work, check that the electrical parts box cover of the indoor unit
and service panel of the outdoor unit are closed, and set the
circuit breaker to the ON position. You may receive an electric
shock if the power is turned on without first conducting these
checks.

• When you have noticed that some kind of trouble (such as
when an error display has appeared, there is a smell of burning,
abnormal sounds are heard, the air conditioner fails to cool or
heat or water is leaking) has occurred in the air conditioner, do
not touch the air conditioner yourself but set the circuit breaker
to the OFF position, and contact a qualified service person.
Take steps to ensure that the power will not be turned on (by
marking “out of service” near the circuit breaker, for instance)
until qualified service person arrives. Continuing to use the air
conditioner in the trouble status may cause mechanical problems
to escalate or result in electric shocks or other failure.

• After the work has finished, be sure to use an insulation tester
set (500V Megger) to check the resistance is 1 MΩ or more
between the charge section and the non-charge metal section
(Earth section). If the resistance value is low, a disaster such as
a leak or electric shock is caused at user’s side.

• Upon completion of the installation work, check for refrigerant
leaks and check the insulation resistance and water drainage.

Then conduct a test run to check that the air conditioner is

operating properly.

• If you have discovered that the fan grille is damaged, do not
approach the outdoor unit but set the circuit breaker to the OFF
position, and contact a qualified service person(*1) to have the
repairs done. Do not set the circuit breaker to the ON position
until the repairs are completed.

• After the installation work, follow the Owner’s Manual to explain
to the customer how to use and maintain the unit.

Relocation

• Only a qualified installer(*1) or qualified service person(*1) is
allowed to relocate the air conditioner. It is dangerous for the air
conditioner to be relocated by an unqualified individual since a
fire, electric shocks, injury, water leakage, noise and/or vibration
may result.

• When carrying out the pump-down work shut down the
compressor before disconnecting the refrigerant pipe.
Disconnecting the refrigerant pipe with the service valve left open
and the compressor still operating will cause air or other gas to
be sucked in, raising the pressure inside the refrigeration cycle to
an abnormally high level, and possibly resulting in rupture, injury
or other trouble.

• Never recover the refrigerant into the outdoor unit. Be sure to
use a refrigerant recovery machine to recover the refrigerant
when moving or repairing. It is impossible to recover the
refrigerant into the outdoor unit. Refrigerant recovery into the
outdoor unit may result in serious accidents such as explosion of
the unit, injury or other accidents.

Explanations given to user

• Upon completion of the installation work, tell the user where the
circuit breaker is located. If the user does not know where the
circuit breaker is, he or she will not be able to turn it off in the
event that trouble has occurred in the air conditioner.

3 Installation of new refrigerant air conditioner

This air conditioner adopts the new HFC refrigerant (R410A) which does not deplete the ozone layer.

• R410A refrigerant is vulnerable to impurities such as water, oxidizing membranes, or oils because the pressure

of R410A refrigerant is higher than that of the former refrigerant by approximately 1.6 times.

As well as the adoption of the new refrigerant, the refrigerating oil has been also changed. Therefore, pay

attention so that water, dust, former refrigerant, or refrigerating oil does not enter the refrigerating cycle of the
new refrigerant air conditioner during installation.

• To prevent mixing of refrigerant or refrigerating oil, the size of the charge port of the main unit or connecting

section of the installation tool differs to that of an air conditioner for the former refrigerant.

Accordingly, exclusive tools are required for the new refrigerant (R410A) as shown below.

• For connecting pipes, use new and clean piping materials so that water or dust does not enter.

 Required tools and cautions on handling

It is necessary to prepare the tools and parts for installation as described below. The tools and parts which will be

4 Selection of installation place

Upon customer’s approval, install the air conditioner in a place which satisfies the following conditions:

• Place where it can be installed horizontally.

• Place which can reserve a sufficient service space for safe maintenance or checks.

• Place where there is no problem even if the drained water overflows.

Avoid the following places:

• Salty places (seaside area) or places with much gas sulfide (hot spring area) (If selecting such a place, special
maintenance is required.)

• Places where oil (including machine oil), steam, oil smoke or corrosive gas is generated.

• Places where iron or other metal dust is present. If iron or other metal dust adheres to or collects on the interior
of the air conditioner, it may spontaneously combust and start a fire.

• Places where an organic solvent is used.

• Chemical plants with a cooling system using liquid carbon dioxide.

• Places where a device generating high frequency (inverter, non-utility generator, medical apparatus, or
communication equipment) is set. (Malfunction or abnormal control of the air conditioner, or interference to
devices listed above may occur.)

• Places where discharged air from the outdoor unit blows against the windows of a neighbour’s house.

• Places unable to bear the weight of the unit.

• Places with poor ventilation.

AMP Air Conditioning

www.ampair.co.uk | [e-mail]

WARNING

• Be sure to install the outdoor unit in a place able to bear its weight.
If strength is insufficient, the unit may fall down resulting in human injury.

• Perform specified installation work to protect against strong wind and earthquakes.
If the outdoor unit is imperfectly installed, an accident by falling or dropping may be caused.

CAUTION

• Drain water is discharged from the outdoor unit. (Especially while heating)
Install the outdoor unit in a place with good drainage.

• For installation, be careful of the strength and level of the foundation so that abnormal sounds (vibration or

noise) are not generated.

REQUIREMENT

Installation in a snowfall area

1. Install the outdoor unit on a higher foundation than the snowfall or set up a stand to install the unit so that

snowfall will not affect the unit.

• Set up a stand higher than the snowfall.

• Apply an angled structure to the stand so that drainage will not be prevented. (Avoid using a stand with a flat

surface.)

2. Mount a snowfall-hood onto the air intake and the air discharge.

5. Be careful of the connecting arrangement of the header unit and follower units. Set the outdoor units in order of
capacity from the one with the largest capacity. (A (Header unit) ≥ B ≥ C)

• Be sure to use a header unit for the leading outdoor unit to be connected to the main pipe. (Figure 1, 3 and 6)

• Be sure to use a T-shaped branch joint (RBM-BT14FE/RBM-BT24FE: separately purchased) to connect each

outdoor unit.

• Be careful of the direction of the Outdoor unit connection piping kit for the liquid side. (As shown in Figure 2, a

Outdoor unit connection piping kit cannot be attached so that the refrigerant of the main pipe flows directly into
the header unit.)

• When attaching a Y-shaped branch unit for the outdoor unit connection piping kit, attach it level with the

ground (Be sure not to exceed ±15 degrees.). Regarding a T-shape branch joints for the liquid side, there is no
restriction for its angle.

7 Refrigerant piping

AMP Air Conditioning

www.ampair.co.uk | [e-mail]

WARNING

• If the refrigerant gas leaks during installation, ventilate the room.
If the leaked refrigerant gas comes into contact with fire, noxious gas may be generated.

• After installation, check that the refrigerant gas does not leak.
If the refrigerant gas leaks into the room and comes into contact with fire such as a fan heater, stove, or

kitchen range, noxious gas may be generated.

 Connection of refrigerant pipe

• The refrigerant pipe connecting section is set in the

outdoor unit. Remove the front panel and the piping/
wiring panel.

• As shown in the illustration on the right, the hooks are

at the right and left sides of the front panel. Lift up and
remove the front panel.

• Pipes can be drawn out forward or downward from the

outdoor unit.

• When drawing out the pipe forward, draw it out to the

outside via the piping/wiring panel, and leave a space
of 500mm or more from the main pipe connecting the
outdoor unit with the indoor unit, considering service
work or other work on the unit. (For replacing the
compressor, 500mm or more space is required.)

• When drawing out the pipe downward, remove the

knockouts on the base plate of the outdoor unit, draw
the pipes out of the outdoor unit, and perform piping
on the right/left or rear side. Downward length of the
balance pipe should be 5m or less.

REQUIREMENT

• For Brazing work of the refrigerant pipes, be sure to use nitrogen gas in order to prevent oxidation of the inside
of the pipes; otherwise clogging of the refrigerating cycle due to oxidized scale may occur.

• Use clean and new pipes for the refrigerant pipes and perform piping work so that water or dust does not
contaminate the refrigerant.

• Be sure to use two spanners to loosen or tighten the flare nut. If a single spanner is used, the required level of
tightening cannot be obtained. Tighten the flare nut with the specified torque. (If it is hard to loosen or tighten the
flare nut of the balance pipe or packed valve of the liquid side with two spanners, loosen or tighten the flare nut
while holding the valve mounting plate with a spanner.)

• When using the conventional flare tool, to connect R410A pipes with flaring, make a margin approx. 0.5mm
longer than that of an R22 pipe so that the flare size matches the one specified. It is convenient to use a copper
pipe gauge for size adjustment of the extruding margin.

• The flared supplied attachment pipe (Ø19.1) must be used to connect with discharge-side gas pipe valve
(Ø19.1). (MAP120 to MAP200) Do not use half hard or hard materials instead of the supplied attachment pipe.
The half hard or hard materials may be cracked and may cause leakage of refrigerant when it is flared.

• Use the flare nut provided with the product.

• After flaring the connection, be sure the flared part is not damaged, deformed, uneven, or flattened, and that
there are no cutting chips on it.

CAUTION

Wrap the ball valve in a wet cloth to keep it cool and prevent the heat from
the torch from damaging it when connecting the pipe to the ball valve on the
suction side gas line.

¿ Capacity code of indoor and outdoor units

Selection of pipe material

• For the indoor unit, the capacity code is decided at each capacity rank. (Table 1)

• The capacity codes of the outdoor units are decided at each capacity rank. The maximum number of
connectable indoor units and the total value of capacity codes of the indoor units are also decided. (Table 2)

NOTE

Compared with the capacity code of the outdoor unit, the total value of capacity codes of the connectable indoor
units differs based on the height difference between the indoor units.

• When the height difference between the indoor units is 15m or less: Up to 135% of the capacity code (Equivalent
to HP) of the outdoor unit.

• When the height difference between the indoor units is over 15m: Up to 105% of the capacity code.

 Airtightness test

After the refrigerant piping has been finished, execute an airtight test.
For an airtight test, connect a nitrogen gas canister as shown in the figure on this page and apply pressure.

• Be sure to apply pressure from the service ports of the packed valves (or ball valves) at the suction gas side,
discharge gas side, liquid side and balance pipe side.

• An airtight test can only be performed at the service ports at the suction gas side, discharge gas side, liquid side
and balance pipe side.

• Close the valves fully at the suction gas side, discharge gas side, liquid side and balance pipe side. As there is
a possibility that the nitrogen gas will enter into the cycle of outdoor units, re-tighten the valve rods at the liquid
side and balance pipe side before applying pressure.

• For each refrigerant line, apply pressure gradually in steps at the suction gas side, discharge gas side, liquid
side and balance pipe side.

Be sure to apply pressure at the suction gas side, discharge gas side, liquid side and balance pipe side.

WARNING

Never use oxygen, flammable gases, or noxious gases in an airtight test.

Able to detect a serious leakage

1. Apply pressure 0.3MPa (3.0kg/cm

2

G) for 5 minutes or more.

2. Apply pressure 1.5MPa (15kg/cm2G) for 5 minutes or more.

Available to detect slow leakage

3. Apply pressure 3.73MPa (38kg/cm2G) for approx. 24 hours.

• If there is no pressure decrease after 24 hours, the test is passed.

NOTE

However, if the environmental temperature changes from the moment of applying pressure to 24 hours after that,
the pressure will change by about 0.01MPa (0.1kg/cm

2

G) per 1°C. Consider the pressure change when checking

the test result.

REQUIREMENT

When pressure decrease is detected in steps 1-3, check the leakage at the connecting points.
Check the leakage using a foaming agent or other measures and seal the leak with re-brazing, flare retightening
or other methods. After sealing, execute an airtight test again.

 Vacuum drying

• Be sure to use a vacuum pump equipped with the counter-flow prevention function so that oil in the pump will
not flow back into piping for air conditioners. (If oil in the vacuum pump enters in the air conditioner with R410A
refrigerant, a problem may be caused in the refrigerating cycle.)

After finishing the airtight test and discharging nitrogen gas, connect the gauge manifold to the service ports of the
suction gas side, discharge gas side, liquid side and balance pipe side and connect a vacuum pump as shown
in the figure below. Be sure to perform vacuuming for the suction gas side, discharge gas side, liquid side and
balance pipe side.

• Use a vacuum pump with a high vacuuming degree [-100.7kPa (5Torr, -755mmHg)] and large exhaust gas
amount (40L/minute or larger).

• Perform vacuuming for 2 or 3 hours, though the time differs depending on the pipe length. Check that all the
valves at the suction gas side, discharge gas side, liquid side and balance pipe side are fully closed.

• If the pressure does not reach -100.7kPa or less even after vacuuming for over 2 hours, continue vacuuming for
1 hour or more. If the pressure does not reach -100.7kPa after 3 hours of vacuuming, stop vacuuming and check
for air leakage.

• If the pressure reaches -100.7kPa or less after vacuuming for 2 hours or more, close the valves VL and VH on
the gauge manifold fully and stop the vacuum pump. Leave it as it is for 1 hour to confirm that the vacuuming
degree does not change.

If the degree of vacuum loss is large, moisture may remain in the pipes. In that case, inject dry nitrogen gas and

apply pressure to 0.05MPa and perform vacuuming again.

• After finishing the above procedure of vacuuming, exchange the vacuum pump with a refrigerant canister and
advance to the additional charging of refrigerant.

Charging of refrigerant

• Keeping the valve of the outdoor unit closed, be sure to charge the liquid refrigerant into the service port at the
liquid side.

• If the specified amount of refrigerant cannot be charged, fully open the valves of the outdoor unit at liquid and
gas sides, operate the air conditioner in COOL mode, and then charge refrigerant into service port at the gas
side. In this time, choke the refrigerant slightly by operating the valve of the canister to charge liquid refrigerant.

• The liquid refrigerant may be charged suddenly, therefore be sure to charge refrigerant gradually.

This equipment complies with IEC 61000-3-12 provided that the short-circuit power Ssc is greater than or equal to Ssc
(*1) at the interface point between the user’s supply and the public system. It is the responsibility of the installer or user
of the equipment to ensure, by consultation with the distribution network operator if necessary, that the equipment is
connected only to a supply with a short-circuit power Ssc greater than or equal to Ssc (*1)

Furthermore, when similar equipment or other equipment which may cause harmonic current emissions are to be
connected to the same interface point with this equipment, to reduce the risk of possible problems which may be
caused from addition of those harmonic current emissions, it is recommended to make sure that the short-circuit power
Ssc at the interface point is greater than the sum of the minimum Ssc required by all the equipment which will be
connected to the interface point.

On this unit, it is required to set the addresses of the indoor units before starting air conditioning.
Set the addresses following the steps below.

CAUTION

• Be sure to complete the electric wiring before setting the addresses.

• If you turn on the outdoor unit before turning on the indoor units, the CODE No. [E19] is indicated on the 7­segment display on the interface P.C. board of the outdoor unit until the indoor units are turned on. This is not a
malfunction.

• It may take up to ten minutes (normally about five minutes) to address one refrigerant line automatically.

• Settings on the outdoor unit are required for automatic addressing. (Address setting is not started simply by
turning on the power.)

• Running the unit is not required for address setting.

• The addresses can be set manually.

Automatic addressing: setting addresses using SW15 on the interface P.C. board on the header outdoor unit
Manual addressing: setting addresses on the wired remote controller.
* When setting an address manually, the wired remote controller must temporarily be paired with an

indoor unit one-to-one. (when the system is organized for group operation and no Remote controller)

REQUIREMENT

• High voltage parts exist in the electrical control box.
If you set addresses on an outdoor unit, operate the
unit through the access door shown on the illustration

Access
door cover

Cover of the electrical
control box

Fixing screw for the
access door cover

on the right to avoid electric shock. Do not remove the
cover of electrical control box.

* After finishing operations, close the access door cover

and fix it with the screw.

REQUIREMENT

• When 2 or more refrigerant lines are controlled as a group, be sure to turn on all the indoor units in the group
before setting addresses.

(Note: The group control of more than two refrigerant systems is possible only when all the FS units are single

port type.)

• If you set the unit addresses of each line separately, each line’s header indoor unit is set separately. In that case,
the CODE No. “L03” (Indoor header unit overlap) is indicated as running starts. Change the group address to
make one unit the header unit using wired remote controller.

WARNINGS ON REFRIGERANT LEAKAGE

Check of Concentration 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 concentration 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 to be imposed which protect
the ozone layer. However, since it contains more than air, it
poses the risk of suffocation if its concentration should rise
excessively.
Suffocation from leakage of R410A is almost non-existent.
With the recent increase in the number of high concentration
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 with
conventional individual air conditioners. If a single unit of the
multi 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 concentration 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 concentration may exceed the limit,
create an opening with adjacent rooms, or install
mechanical ventilation combined with a gas leak detection
device.
The concentration is as given below.

Total amount of refrigerant (kg)

Min. volume of the indoor unit installed room (m

≤ Concentration limit (kg/m

The concentration limit of R410A which is used in multi air
conditioners is 0.3kg/m

NOTE 1 :

If there are 2 or more refrigerating systems in a single
refrigerating device, the amounts of refrigerant should be
as charged in each independent device.

e.g., charged
amount (10kg)

Room A Room B Room C Room D Room E Room F

For the amount of charge in this example:

The possible amount of leaked refrigerant gas in rooms
A, B and C is 10kg.
The possible amount of leaked refrigerant gas in rooms
D, E and F is 15kg.

Important

NOTE 2 :

The standards for minimum room volume are as follows.
(1) No partition (shaded portion)

(2) When there is an effective opening with the adjacent

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 piping is interconnected,
the smallest room of course becomes the object.
But when a 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.
