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.

5-EN 6-EN

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.
