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.

• Only a qualified installer or service person is allowed to do installation work. Inappropriate installation may result in water leakage, electric shock or fire.

• 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 electrical control box cover of the indoor unit or 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 electrical control box cover of the indoor unit or service panel of the outdoor unit and do the work required.

• Before carrying out the installation, maintenance, repair or removal work, set the circuit breaker to the OFF position. Otherwise, electric shocks 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 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.

• Before opening the inspection opening, set the circuit breaker to the OFF position. Failure to set the circuit breaker to the OFF position may result in injury through contact with the rotation parts. Only a qualified installer (*1) or qualified service person (*1) is allowed to remove the inspection opening and do the work required.

• When work is performed at heights, use a ladder which complies with the ISO 14122 standard, and follow the procedure in the ladder’s instructions. Also wear a helmet for use in industry as protective gear to undertake the work.

• Before 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.

• Before 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. While carrying out the work, wear a helmet for protection from falling objects.

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

• The air conditioner must be transported in stable condition. If any part of the product is broken, contact the dealer.

• When the air conditioner must be transported by hand, carry it by two or more people.

• Do not move or repair any unit by yourself. There is high voltage inside the unit. You may get electric shock when removing the cover and main unit.

Selection of installation location

• When the air conditioner is installed in a small room, provide appropriate measures to ensure that the concentration of refrigerant leakage occur in the room does not exceed the critical level.

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

• To transport the air conditioner, wear shoes with additional protective toe caps.

• To transport 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.

Installation

• Suction duct length must be longer than 850 mm.

• When the indoor unit is to be suspended, the designated hanging bolts (M10 or W3/8) and nuts (M10 or W3/8) must be used.

• Install the air conditioner securely in a location where the base can sustain the weight adequately. If the strength is not enough, the unit may fall down resulting in injury.

• 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 trouble.

• Carry out the specified installation work to guard against the possibility of high winds and earthquake. If the air conditioner is not installed appropriately, a unit may topple over or fall down, causing an accident.

• 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 generate.

• Use forklift to carry in the air conditioner units and use winch or hoist at installation of them.

• Helmet must be worn to protect your head from falling objects. Especially, when you work under an inspection opening, helmet must be worn to protect your head from falling objects from the opening.

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.

• 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.

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.

• To connect the electrical wires, repair the electrical parts or undertake 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.

• 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.

• Connect earth wire. (Grounding work) Incomplete grounding causes an electric shock.

• Do not connect earth wires to gas pipes, water pipes, and lightning conductor or telephone earth wires.

• After completing the repair or relocation work, check that the earth 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 the power wire must not be extended. Connection trouble in the places where the wire 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.

Test run

CAUTION

• 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.

• If there is any kind of trouble (such as an error display has appeared, smell of burning, abnormal sounds, 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 trouble.

• After the work has finished, use an insulation tester set (500 V 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.

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.

• 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.

3 Selection of installation place

Avoid installing in the following places

Select a location for the indoor unit where the cool or warm air will circulate evenly. Avoid installation in the following kinds of locations.

• Saline area (coastal area)

• Locations with acidic or alkaline atmospheres (such as areas with hot springs, factories where chemicals or pharmaceuticals are made and places where the exhaust air from combustion appliances will be sucked into the unit). Doing so may cause the heat exchanger (its aluminum fins and copper pipes) and other parts to become corroded.

• Locations with atmospheres with mist of cutting oil or other types of machine oil. Doing so may cause the heat exchanger to become corroded, mists caused by the blockage of the heat exchanger to be generated, the plastic parts to be damaged, the heat insulators to peel off, and other such problems to result.

• 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.

• Locations where vapors from food oils are formed (such as kitchens where food oils are used). Blocked filters may cause the air conditioner’s performance to deteriorate, condensation to form, the plastic parts to be damaged, and other such problems to result.

• Locations near obstructions such as ventilation openings or lighting fixtures where the flow of the blown air will be disrupted (a disruption of the air flow may cause the air conditioner’s performance to deteriorate or the unit to shut down).

• Locations where an in-house power generator is used for the power supply. The power line frequency and voltage may fluctuate, and the air conditioner may not work properly as a result.

• On truck cranes, ships or other moving conveyances.

• The air conditioner must not be used for special applications (such as for storing food, plants, precision instruments or art works). (The quality of the items stored may be degraded.)

• Locations where high frequencies are generated (by inverter equipment, in-house power generators, medical equipment or communication equipment). (Malfunctioning or control trouble in the air conditioner or noise may adversely affect the equipment’s operation.)

• Locations where there is anything under the unit installed that would be compromised by wetness. (If the drain has become blocked or when the humidity is over 80 %, condensation from the indoor unit will drip, possibly causing damage to anything underneath.)

• In the case of the wireless type of system, rooms with the inverter type of fluorescent lighting or locations exposed to direct sunlight. (The signals from the wireless remote controller may not be sensed.)

• Locations where organic solvents are being used.

• The air conditioner cannot be used for liquefied carbonic acid cooling or in chemical plants.

• Location near doors or windows where the air conditioner may come into contact with high-temperature, highhumidity outdoor air. (Condensation may occur as a result.)

• Locations where special sprays are used frequently.

 Installation under high-humidity atmosphere

In some cases including the rainy season, especially inside of the ceiling may become high-humidity atmosphere (dew-point temperature: 23 °C or higher).

1. Installation to inside of the ceiling with tiles on the roof

2. Installation to inside of the ceiling with slated roof

3. Installation to a place where inside of the ceiling is used for pathway to intake the fresh air

4. Installation to a kitchen

• In the above cases, additionally attach the heat insulator to all positions of the air conditioner, which come to contact with the high-humidity atmosphere. In this case, arrange the side plate (Check port) so that it is easily removed.

• Apply also a sufficient heat insulation to the duct and connecting part of the duct.

Following the Installation Manual, perform the drain piping work so that water is properly drained. Apply a heat insulation so as not to cause a dew condensation. Inappropriate piping work may result in water leakage in the room and wet furniture.

• Provide the indoor drain piping with proper heat insulation.

• Provide the area where the pipe connects to the indoor unit with proper heat insulation. Improper heat insulation will cause condensation to form.

• The drain pipe must be sloping downward (at an angle of 1/100 or more), and do not run the pipe up and down (arched shape) or allow it to form traps. Doing so may cause abnormal sounds.

• Restrict the length of the traversing drain pipe to 20 meters or less. For a long pipe, provide support brackets at intervals of 1.5 to 2 meters to prevent flapping.

• Install the collective piping as shown in the following figure.

• Do not provide any air vents. Otherwise, the drain water will spout, causing water to leak.

• Do not allow any force to be applied to the connection area with the drain pipe.

 Pipe material, size and insulator

The following materials for piping work and insulating process are locally procured.

Pipe material Hard vinyl chloride pipe VP25 (Nominal outer diameter Ø32 mm)

Insulator Foamed polyethylene foam, thickness: 10 mm or more

 Gravitational drainage

1 Reattach the drain cap.

* For gravitational drainage, remove the white connector

(CN504) on the upper left of the circuit board in the electrical control box.

2 Insert flexible drain hose into lower drain pipe and

fix it with hose band.

3 Remove drain pump connector CN504.

 Drain up

When a down-gradient cannot be secured for the drain pipe, drain-up piping is possible.

• The height of the drain pipe must be 850 mm or less from the underside of the indoor unit.

• Take the drain pipe out of the drain pipe joint with the indoor unit in 300 mm or less, and bend up the pipe vertically.

• Immediately after the pipe is bent up vertically, lay the pipe making a down-gradient.

 Connecting drain pipe

Insert flexible drain hose into upper drain pipe of main unit as far as it will go. Fix it with hose band.

Mount the flexible drain hose using the hose band without using adhesive.

 Check the draining

In the test run, check that water drain is properly performed and water does not leak from the connecting part of the pipes. When doing this, also check that no abnormal sounds are heard from the drain pump motor. Check draining also when installed in heating period.

When the electrical and wiring work has been completed

Pour some water by following the method shown in the following figure. Then, while performing a cooling operation, check that the water drains from the drain pipe connecting port (transparent) and that no water is leaking from the drain pipe.

When the electrical and wiring work has not been completed

• Disconnect the float switch connector (3P: red) from the connector (CN34: red) on the printed circuit board inside the electrical control box. (Before doing this, the power must be turned off.)

• Connect a 220 V to 240 V supply voltage to (L) and (N) on the power supply terminal block. (Do not apply a 220 V to 240 V voltage to (A), (B), (U damaged.)

• Pour the water by following the method shown in the following figure. (Amount of water poured: 1500 cc to 2000 cc)

• When the power is turned on, the drain pump automatically starts running. Check whether the water is draining from the drain pipe connecting port, and check that no water is leaking from the drain pipe.

• After checking that the water drains and there are no water leaks, turn off the power, connect the float switch connector to its original location (CN34) on the printed circuit board, and return the electrical control box to its original position.

7 Refrigerant piping

CAUTION

REQUIREMENT

Work using double spanner

When the refrigerant pipe is long, provide support brackets at intervals of 2.5 m to 3 m to clamp the refrigerant pipe. Otherwise, abnormal sound may be generated. Use the flare nut attached with the indoor unit or R410A flare nut.

 Permissible piping length and

height difference

They vary depending on the outdoor unit. For details, refer to the Installation Manual attached to the outdoor unit.

 Pipe size

 Connecting refrigerant piping

Flaring

1. Cut the pipe with a pipe cutter. Remove burrs completely. (Remaining burrs may cause gas leakage.)

2. Insert a flare nut into the pipe, and flare the pipe. Use the flare nut provided with the unit or the one used for the R410A refrigerant. The flaring dimensions for R410A are different from the ones used for the conventional R22 refrigerant. A new flare tool manufactured for use with the R410A refrigerant is recommended, but the conventional tool can still be used if the projection margin of the copper pipe is adjusted to be as shown in the following table.

• Tightening torque of flare pipe connections. Pressure of R410A is higher than that of R22. (Approx. 1.6 times) Therefore, using a torque wrench, tighten the flare pipe connecting sections which connect the indoor and outdoor units of the specified tightening torque. Incorrect connections may cause not only a gas leak, but also a trouble of the refrigeration cycle.

Tightening with an excessive torque may crack the nut depending on installation conditions.

Tightening torque (N•m)

 Evacuation

Perform vacuuming from the charge port of valve of the outdoor unit by using a vacuum pump. For details, follow to the Installation Manual attached to the outdoor unit.

• Do not use the refrigerant sealed in the outdoor unit for evacuation.

For the tools such as charge hose, use those manufactured exclusively for R410A.

Refrigerant amount to be added

For addition of the refrigerant, add refrigerant “R410A” referring to the attached Installation Manual of outdoor unit. Use a scale to charge the refrigerant of specified amount.

• Charging an excessive or too little amount of refrigerant causes a trouble of the compressor. Charge the refrigerant of specified amount.

• A personnel who charged the refrigerant should write down the pipe length and the added refrigerant amount in the F-GAS label of the outdoor unit. It is necessary to fix the compressor and refrigeration cycle malfunction.

Open the valve fully

Open the valve of the outdoor unit fully. A 4 mmhexagonal wrench is required for opening the valve. For details, refer to the Installation Manual attached to the outdoor unit.

Gas leak check

Check with a leak detector or soap water whether gas leaks or not, from the pipe connecting section or cap of the valve.

Use a leak detector manufactured exclusively for HFC refrigerant (R410A, R134a).

* In case of flaring for R410A with the conventional

flare tool, pull it out approx. 0.5 mm more than that for R22 to adjust to the specified flare size. The copper pipe gauge is useful for adjusting projection margin size.

 Group control

In a group control, a remote controller can control up to maximum 8 units.

• The wired remote controller only can control a group control. The wireless remote controller is unavailable for this control.

• For wiring procedure and wires of the individual line (Identical refrigerant line) system, refer to “Electrical Connection” in this Manual.

• Wiring between indoor units in a group is performed in the following procedure.

• Connect the indoor units by connecting the remote controller wires from the remote controller terminal blocks (A, B) of the indoor unit connected with a remote controller to the remote controller terminal blocks (A, B) of the other indoor unit. (Non-polarity)

• For address setup, refer to the Installation Manual attached to the outdoor unit.

10Test run

 Before test run

• Before turning on the power supply, carry out the following procedure.

1) By using 500 V-megger, check that resistance of 1 MΩ or more exists between the terminal block L to N and the earth (grounding). If resistance of less than 1 MΩ is detected, do not run the unit.

2) Check the valve of the outdoor unit being opened fully.

• To protect the compressor at activation time, leave power-ON for 12 hours or more before operating.

• Do not press the electromagnetic contactor to forcibly perform a test run. (This is very dangerous because the protective device does not work.)

• Before starting a test run, set addresses by following the Installation Manual supplied with the outdoor unit.

 Execute a test run

• When a fan operation is to be performed for an individual indoor unit, turn off the power, short CN72 on the circuit board, and then turn the power back on. (First set the operating mode to “fan,” and then operate.) When the test run has been performed using this method, do NOT forget to release the shorting of CN72 after the test run is completed.

Operate the unit with the wired remote controller as usual. For the procedure of the operation, refer to the attached Owner’s Manual to the outdoor unit. A forced test run can be executed in the following procedure even if the operation stops by thermostatOFF. In order to prevent a serial operation, the forced test run is released after 60 minutes have passed and returns to the usual operation.

Do not use the forced test run for cases other than the test run because it applies an excessive load to the devices.

Check wiring / piping of the indoor and outdoor units in test run.

 When a test run is not

performed properly

• When a test run is not performed properly, refer to the error code and the part to be checked on “Troubleshooting”.

• When a test run is executed before installing the external duct, a protection control may be activated and lets the unit stop and the code P12 may be displayed. (This is not due to a malfunction but to the current control function of the DC motor in this unit.) When a test run executed before installing the external duct, select “Low” for the fan speed level or cover the air discharge.

• In addition, stop the operation before replacing the High-efficiency filter or opening the service panel. After the test run, reset the circuit breaker of the indoor unit.

which an error occurred

▼ Periodic Maintenance

For environmental conservation, it is strongly recommended that the indoor and outdoor units of the air conditioner in use be cleaned and maintained regularly to ensure efficient operation of the air conditioner. When the air conditioner is operated for a long time, periodic maintenance (once a year) is recommended. Furthermore, regularly check the outdoor unit for rust and scratches, and remove them or apply rustproof treatment, if necessary. As a general rule, when an indoor unit is operated for 8 hours or more daily, clean the indoor unit and outdoor unit at least once every 3 months. Ask a professional for this cleaning / maintenance work. Such maintenance can extend the life of the product though it involves the owner’s expense. Failure to clean the indoor and outdoor units regularly will result in poor performance, freezing, water leakage, and even compressor failure.

▼ Inspection before maintenance (Once a year)

Following inspection must be carried out by a qualified installer or qualified service person.

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.

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.

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.

▼ 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.

49-EN 50-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.

1) No partition (shaded portion)
