60245 IEC66 (1.5 mm
2
or more) (Shall be installed in accordance with national wiring regulations).
New refrigerant air conditioner installation
CAUTION
• THIS AIR CONDITIONER USES THE NEW HFC REFRIGERANT (R410A), WHICH DOES NOT DESTROY THE OZONE LAYER.
R410A refrigerant is apt to be affected by impurities such as water, oxidizing membranes, and oils because the pressure of R410A refrigerant is approx.
1.6 times of refrigerant R22. As well as the adoption of this new refrigerant, refrigerating machine oil has also been changed. Therefore, during installation
work, be sure that water, dust, former refrigerant, or refrigerating machine oil does not enter the refrigeration cycle of a new-refrigerant air conditioner.
To avoid mixing refrigerant and refrigerating machine oil, the sizes of charging port connecting sections on the main unit are different from those for the
conventional refrigerant, and different size tools are also required. For connecting pipes, use new and clean piping materials with highpressure withstand
capabilities, designed for R410A only, and ensure that water or dust does not enter. Moreover, do not use any existing piping as its pressure withstand
may be insuffi cient and may contain impurities.
DANGER
• FOR USE BY QUALIFIED PERSONS ONLY.
• MEANS FOR DISCONNECTION FROM THE SUPPLY HAVING A CONTACT SEPERATION OF AT LEAST 3 mm IN ALL POLES MUST BE
INCORPORATED IN THE FIXED WIRING.
• TURN OFF MAIN POWER SUPPLY BEFORE ATTEMPTING ANY ELECTRICAL WORK. MAKE SURE ALL POWER SWITCHES ARE OFF.
FAILURE TO DO SO MAY CAUSE ELECTRIC SHOCK.
• CONNECT THE CONNECTING CABLE CORRECTLY. IF THE CONNECTING CABLE IS CONNECTED WRONGLY, ELECTRIC PARTS MAY BE
DAMAGED.
• CHECK THE EARTH WIRE THAT IT IS NOT BROKEN OR DISCONNECTED BEFORE INSTALLATION.
• DO NOT INSTALL NEAR CONCENTRATIONS OF COMBUSTIBLE GAS OR GAS VAPORS. FAILURE TO FOLLOW THIS INSTRUCTION CAN
RESULT IN FIRE OR EXPLOSION.
• TO PREVENT OVERHEATING THE INDOOR UNIT AND CAUSING A FIRE HAZARD, PLACE THE UNIT WELL AWAY (MORE THAN 2 M) FROM
HEAT SOURCES SUCH AS RADIATORS, HEATERS, FURNACE, STOVES, ETC.
• WHEN MOVING THE AIR CONDITIONER FOR INSTALLING IT IN ANOTHER PLACE AGAIN, BE VERY CAREFUL NOT TO GET THE SPECIFIED
REFRIGERANT (R410A) WITH ANY OTHER GASEOUS BODY INTO THE REFRIGERATION CYCLE. IF AIR OR ANY OTHER GAS IS MIXED IN
THE REFRIGERANT, THE GAS PRESSURE IN THE REFRIGERATION CYCLE BECOMES ABNORMALLY HIGH AND IT RESULTINGLY CAUSES
BURST OF THE PIPE AND INJURIES ON PERSONS.
• IN THE EVENT THAT THE REFRIGERANT GAS LEAKS OUT OF THE PIPE DURING THE INSTALLATION WORK, IMMEDIATELY LET FRESH AIR
INTO THE ROOM. IF THE REFRIGERANT GAS IS HEATED BY FIRE OR SOMETHING ELSE, IT CAUSES GENERATION OF POISONOUS GAS.
• WHEN INTALLING OR RE-INSTALLING THE AIR CONDITIONER, DO NOT INJECT AIR OR OTHER SUBSTANCES BESIDES THE DESIGNATED
REFRIGERANT “R410A” INTO THE REFRIGERATING CYCLE. IF AIR OR OTHER SUBSTANCES ARE MIXED, AN ABNORMAL PRESSURE CAN
OCCUR IN THE REFRIGERATING CYCLE, AND THIS CAN CAUSE AN INJURY DUE TO A PIPE RUPTURE.

• Exposure of unit to water or other moisture before installation could result in electric shock. Do not store it in a wet basement or expose to rain or water.
• After unpacking the unit, examine it carefully for possible damage.
• Do not install in a place that can increase the vibration of the unit. Do not install in a place that can amplify the noise level of the unit or where noise and
discharged air might disturb neighbors.
• This appliance must be connected to the main power supply by means of a circuit breaker depending on the place where the unit is installed. Failure to
do so may cause electrical shock.
• Follow the instructions in this installation manual to arrange the drain pipe for proper drainage from the unit. Ensure that drained water is discharged.
Improper drainage can result in water leakage, causing water damage to furniture.
• Tighten the fl are nut with a torque wrench using the prescribed method. Do not apply excess torque. Otherwise, the nut may crack after a long period of
usage and it may cause the leakage of refrigerant.
• Wear gloves (heavy gloves such as cotton gloves) for installation work. Failure to do so may cause personal injury when handling parts with sharp
edges.
• Do not touch the air intake section or the aluminum fi ns of the outdoor unit. It may cause injury.
• Do not install the outdoor unit in a place which can be a nest for small animals. Small animals could enter and contact internal electrical parts, causing a
failure or fi re.
• Request the user to keep the place around the unit tidy and clean.
• Make sure to conduct a trial operation after the installation work, and explain how to use and maintain the unit to the customer in accordance with the
manual. Ask the customer to keep the operation manual along with the installation manual.
REQUIREMENT OF REPORT TO THE LOCAL POWER SUPPLIER
Please make absolutely sure that the installation of this appliance is reported to the local power supplier before installation. If you experience any problems
or if the installation is not accepted by the supplier, the service agency will take adequate countermeasures.
WARNING
• Installation work must be requested from the supplying retail dealership or professional vendors. Self-installation may cause water leakage, electrical
shock, or fi re as a result of improper installation.
• Specifi ed tools and pipe parts for model R410A are required, and installation work must be done in accordance with the manual. HFC type refrigerant
R410A has 1.6 times more pressure than that of conventional refrigerant (R22). Use the specifi ed pipe parts, and ensure correct installation, otherwise
damage and/or injury may be caused. At the same time, water leakage, electrical shock, and fi re may occur.
• Be sure to install the unit in a place which can suffi ciently bear its weight. If the load bearing of the unit is not enough, or installation of the unit is
improper, the unit may fall and result in injury.
• Electrical work must be performed by a qualifi ed electrical engineer in accordance with the code governing such installation work, internal wiring
regulations, and the manual. A dedicated circuit and the rated voltage must be used. Insuffi cient power supply or improper installation may cause
electrical shock or fi re.
• Use a cabtyre cable to connect wires in the indoor/outdoor units. Midway connection, stranded wire, and single-wire connections are not allowed.
Improper connection or fi xing may cause a fi re.
• Wiring between the indoor unit and outdoor units must be well shaped so that the cover can be fi rmly placed. Improper cover installation may cause
increased heat, fi re, or electrical shock at the terminal area.
• Be sure to use only approved accessories or the specifi ed parts. Failure to do so may cause the unit to fall, water leakage, fi re or electrical shock.
• After the installation work, ensure that there is no leakage of refrigerant gas. If the refrigerant gas leaks out of the pipe into the room and is heated by
fi re or something else from a fanheater, stove or gas range, it causes generation of poisonous gas.
• Make sure the equipment is properly earthed. Do not connect the earth wire to a gas pipe, water pipe, lightning conductor, or telephone earth wire.
Improper earth work may be the cause of electrical shock.
• Do not install the unit where fl ammable gas may leak. If there is any gas leakage or accumulation around the unit, it can cause a fi re.
• Do not select a location for installation where there may be excessive water or humidity, such as a bathroom. Deterioration of insulation may cause
electrical shock or fi re.
• Installation work must be performed following the instructions in this installation manual. Improper installation may cause water leakage, electrical shock
or fi re. Check the following items before operating the unit.
- Be sure that the pipe connection is well placed and there are no leaks.
- Check that the service valve is open. If the service valve is closed, it may cause overpressure and result in compressor damage. At the same time, if
there is a leak in the connection part, it may cause air suction and overpressure, resulting burst or injury.
• In pump down operations, ensure to perform the following procedures.
- Do not inject air into the refrigeration cycle.
- Be sure to close both service valves and stop the compressor before removing the refrigerant pipe. If removing the refrigerant pipe while the
compressor is operating with the service valves opened, it may cause to air absorbed and abnormal high pressure inside the refrigeration cycle and
resulting burst or injury.
• Do not modify the power cable, connect the cable midway, or use a multiple outlet extension cable. Doing so may cause contact failure, insulation
failure, or excess current, resulting in fi re or electrical shock.
• If you detect any damage, do not install the unit. Contact your supplying dealer immediately.
• Never modify this unit by removing any of the safety guards or bypassing any of the safety interlock switches.

• Tightening torque for connection of fl are pipe
The pressure of R410A is higher than R22
(Approx. 1.6 times). Therefore securely
tighten the fl are pipes which connect the
outdoor unit and the indoor unit with the
specifi ed tightening torque using a torque
wrench. If any fl are pipe is incorrectly
connected, it may cause not only
a gas leakage but also trouble in the
refrigeration cycle.

Wiring Connection
1. Remove the valve cover, the electric parts cover and the cord clamp from
the outdoor unit.
2. Connect the connecting cable to the terminal as identifi ed by the matching
numbers on the terminal block of indoor and outdoor unit.
3. Insert the power cord and the connecting cable fully into the terminal
block and secure it tightly with screws.
4. Use vinyl tape, etc. to insulate the cords which are not going to be used.
Locate them so that they do not touch any electrical or metal parts.
5. Secure the power cord and the connecting cable with the cord clamp.
6. Attach the electric parts cover and the valve cover on the outdoor unit.
Electrical Work
1. The supply voltage must be the same as the rated voltage of the air
conditioner.
2. Prepare the power source for exclusive use with the air conditioner.
Packed valve handling precautions
• Open the valve stem until it touches the stopper. Once it is in contact with
the stopper, refrain from applying any more force than is necessary.
• Securely tighten the valve stem cap with torque in the following table:
Evacuating
After the piping has been connected to the indoor unit, you can perform
vacuuming together at once.
Using a vacuum pump
Be sure to use a vacuum pump with counter-fl ow prevention function so
that inside oil of the pump does not fl ow backward into pipes of the air
conditioner when the pump stops.
(If oil inside of the vacuum pump enters the air conditioner, which use
R410A, refrigeration cycle trouble may happen.)
1. Connect the charge hose from the manifold valve to the service port of the
packed valve at gas side.
2. Connect the charge hose to the port of the vacuum pump.
3. Open fully the low pressure side handle of the gauge manifold valve.
4. Operate the vacuum pump to start evacuating. Perform evacuating for
about 15 minutes if the piping length is 20 meters
(15 minutes for 20
meters) (assuming a pump capacity of 27 liters per minute). Then confi rm
that the compound pressure gauge reading is –101 kPa (–76 cmHg).
5. Close the low pressure side valve handle of the gauge manifold valve.
6. Open fully the valve stem of the packed valves (both gas and liquid
sides).
7. Remove the charging hose from the service port.
8. Securely tighten the caps on the packed valves.
VACUUMING
Evacuate the air in the connecting pipes and in the indoor unit using a
vacuum pump. Do not use the refrigerant in the outdoor unit. For details,
see the manual of the vacuum pump.

Remote control selector switch
• When two indoor units are installed in the same room or adjacent two
rooms, if operating a unit, two units may receive the remote control
signal simultaneously and operate. In this case, the operation can
be preserved by setting either one indoor unit or remote control to B
setting (Both are set to A setting in factory shipment).
• The remote control signal is not received when the settings of indoor
unit and remote control are different.
• There is no relation between A setting/B setting and A room/B room
when connecting the piping and cables.
When two indoor units are installed in the separated rooms, it is not
necessary to change the selector switches.

Installation av luftkonditionering med nytt kylmedel
VAR FÖRSIKTIG
• LUFTKONDITIONERINGSAGGREGATET ANVÄNDER HFC-KÖLDMEDIET (R410A) SOM INTE FÖRSTÖR OZONLAGRET.
Köldmediet R410A har benägenheten att lätt bli förorenat av vatten, oxiderande membran och oljor eftersom R410A har ett tryck som är ungefär 1,6
gånger så högt som för R22. Förutom att ett nytt köldmedium används, så har även kyloljan i aggregatet bytts. Därför är det viktigt att se till att inget
vatten, damm, äldre sorters köldmedium eller maskinkylolja kommer in i kylkretsen på luftkonditioneringsaggregat som använder denna nya typ av
köldmedium. För att undvika att köldmedium och maskinkylolja blandas, så är huvudenhetens påfyllningsportar och anslutningsdelar av en annan
storlek än de för konventionellt köldmedium, och det krävs också verktyg av andra storlekar. Till förbindelserör ska endast nya och rena rörledningar
som enbart är avsedda för R410A och tål högt tryck användas. Se till att vatten eller damm inte kommer in i ledningarna. Befintliga rörledningar kan
vara förorenade, och kanske inte klarar av det höga trycket. De ska därför inte användas.
