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 installationwork. 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.

• When working at heights, put a sign in place so that no-one will approach the work location, before proceeding with the

work. Parts and other objects may fall from above, possibly injuring a person below.

• 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, repair or move the product yourself. Doing so may cause fire, electric shock, injury or water

leaks. Ask a qualified installer or qualified service person to do any repairs or to move the product.

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.

• 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.

• Places where the operation sound of the outdoor unit 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 wire to a gas pipe, water pipe, lightning conductor, or a telephone earth wire.

• 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.

Test run

• Before operating the air conditioner after having completed the work, check that the electrical control 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 (500 V Megger) to check the resistance is 2 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.

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.

• 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.

5-EN 6-EN

–4–

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 compr essor 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.

(*1) Refer to the “Definition of Qualified Installer or Qualified Service Person.”

CAUTION

New refrigerant air conditioner installation

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

• The characteristics of R410A refrigerant are; easy to absorb water, oxidizing membrane or oil, and its pressure is approx.

1.6 times higher than that of refrigerant R22. Accompanied with the new refrigerant, refrigerating oil has also been changed.

Therefore, during installation work, be sure that water, dust, former refrigerant, or refrigerating oil does not enter the

refrigerating cycle.

• To prevent charging an incorrect refrigerant and refrigerating oil, the sizes of connecting sections of charging port of the

main unit and installation tools are changed from those for the conventional refrigerant.

• Accordingly the exclusive tools are required for the new refrigerant (R410A).

• For connecting pipes, use new and clean piping designed for R410A, and please care so that water or dust does not enter.

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

newly prepared in the following items should be restricted to exclusive use.

6 Installation of the outdoor unit

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.

• Leave enough space for the snowfall-hood so that it will not be an obstacle for the air intake and the air

discharge.

1. To install multiple outdoor units, arrange them with 20 mm or more spaces in between.

Fix each outdoor unit with M12 anchor bolts at 4 positions. 20 mm projection is appropriate for an anchor bolt.

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)

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

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

each outdoor unit.

3) 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.

4) 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.)

7 Refrigerant piping

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

1. The refrigerant pipe connecting section is set in the

outdoor unit. Remove the front panel and the piping /

wiring panel. (M5: 9 pcs.)

• 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.

2. Pipes can be drawn out forward or downward from the

outdoor unit.

3. When drawing out the pipe forward, draw it out to the

outside via the piping / wiring panel, and leave a space

of 500 mm 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, 500 mm or more space is required.)

4. 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 5 m or less.

5. Wrap a wet cloth around the valve of the pipe

connector valve to keep it cool during brazing.

(If it is not cooled enough, the heat may affect the

packing in the valve and cause gas leaks)

REQUIREMENT

• For a 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.

* Remove all flux after brazing.

• Be sure to use a double spanner 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 a double spanner, loosen or tighten the

flare nut while holding the valve mounting plate with a spanner.)

Extruding margin of copper pipe with flare tools: A (Unit: mm)

• When using the conventional flare tool, to connect R410A pipes with flaring, make a margin approx. 0.5 mm

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 (Ø19.1) of

MAP120 and MAP140. 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.
