WARNING

1 Precautions for safety

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

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

Relocation

CAUTION

• 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.”

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.

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.

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.)

• 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)

• 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.)

• 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.

 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 below and apply pressure.

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

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

• Close the valves fully at the 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 liquid side, discharge gas side, suction gas side and balance pipe side.

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

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

Able to detect a serious leakage

1. Apply pressure 0.3 MPa (3.0 kg/cm²G) for 5 minutes or more.

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

Available to detect slow leakage

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

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

However, if the environmental temperature changes from the moment of applying pressure to 24 hours after that, the pressure will change by about 0.01 MPa (0.1 kg/cm²G) per 1 °C. Consider the pressure change when checking the test result.

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.

NOTE

• 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 liquid side , discharge gas side, suction gas side, and balance pipe side and connect a vacuum pump as shown in the figure below. Be sure to perform vacuuming for the liquid, discharge gas side, suction gas side, and balance pipe sides.

 Adding refrigerant

After finishing vacuuming, exchange the vacuum pump with a refrigerant canister and start additional charging of refrigerant.

Calculation of additional refrigerant charge amount

Refrigerant charge amount factory default does not include the refrigerant for pipes at the local site. For refrigerant to be charged in pipes at the local site, calculate the amount and charge it additionally.

If the additional refrigerant amount indicates minus as the result of calculation, use the air conditioner without additional refrigerant.

• Use a vacuum pump with a high vacuuming degree [-100.7 kPa (5 Torr, -755 mmHg)] and large exhaust gas amount (40 L/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 liquid side, discharge gas side, suction gas side, and balance pipe side are fully closed.

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

• If the pressure reaches -100.7 kPa 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 0.05 MPa 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.

• To protect the world's environment, do not release chlorofluorocarbons into the atmosphere.

• Do not do an air purge including used refrigerant.

 Before test run

Confirm that the valve of the refrigerate pipe of the outdoor unit is OPEN.

• Before turning on the power, confirm that the resistance between the terminal block of power supply and the earth is more than 1 MΩ using a 500 V megohmmeter. Do not run the unit if it is less than 1 MΩ.

• Turn on the power and turn on the case heater of the compressor. To save the compressor when it is activated, leave the power on for more than 12 hours.

 Methods of test run

◆ When executing a test run using a remote controller

Operate the system normally to check the running condition using the wired remote controller. Follow the instructions in the supplied owner’s manual when operating the unit. If you use a wireless remote controller for operations, follow the instructions in the installation manual supplied with the indoor unit. To execute a test run forcibly under the condition that the thermostat automatically turns the unit off due to the indoor temperature, follow the procedure below. The forcible test run will automatically stop after 60 minutes to prevent continuous forcible running and return to normal running.

1 Push and hold the button for more than 4

seconds. TEST appears on the LCD display and the unit enters the trial mode. (TEST is indicated on the LCD display during the test run.)

2 Push the button. 3 Push the button to switch the running

mode to COOL or HEAT.

• Do not run the unit in any mode other than COOL or HEAT.

• You cannot change the temperature setting during the test run.

• Errors are detected as usual.

◆ When executing a test run using the interface P.C. board on the outdoor unit

▼ Starting operation

1 Set the running mode to “COOL” or “HEAT”

on the remote controller of the indoor unit to be tested. (The unit will run in the current mode unless you set the mode otherwise.)

2 Set the rotary switches on the interface P.C.

board of the header outdoor unit: SW01 to [16], SW02 and SW03 to the address of the indoor unit to be tested.

SW02 SW03 Indoor unit address

1 to 16 1 1 to 16 Set number of SW02

1 to 16 2 17 to 32 Set number of SW02 + 16

1 to 16 3 33 to 48 Set number of SW02 + 32

• The running mode follows the mode setting on the remote controller of the target indoor unit.

• You cannot change the temperature setting during the test run.

• Errors are detected as usual.

• The unit does not perform test run for 3 minutes after turning the power on or stopping running.

▼ Finishing operation

1 Set the rotary switches on the interface P.C.

board of the header unit back: SW01 to [1], SW02 to [1] and SW03 to [1].

Total amount of refrigerant

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)

≤ Concentration limit (kg/m

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

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.

▼ NOTE 3

The minimum indoor floor area compared with the amount of refrigerant is roughly as follows: (When the ceiling is 2.7 m high)

For the amount of charge in this example:

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

69-EN 70-EN

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

▼ NOTE 2

The standards for minimum room volume are as follows.
