PRECAUTIONS FOR SAFETY
PRECAUTIONS FOR SAFETY
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 high pressure 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 INSTALLING 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.

WARNING
• Installation work must be requested from the supplying retail dealership. 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 supplying retail dealership 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 fan heater, 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.
• Do not use any refrigerant different from the one specifi ed 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.
• Be sure to comply with local regulations/codes when running the wire from the outdoor unit to the indoor unit. (Size of wire and wiring method etc.)
• 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 fi re.
• 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.
• Do not install in a place which cannot bear the weight of the unit. Personal injury and property damage can result if the unit falls.
CAUTION
• Please read this installation manual carefully before installing the unit. It contains further important instructions for proper installation.
• 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.

Evacuating
After the piping has been connected to the indoor unit, you can perform the air purge together at once.
AIR PURGE
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.
• Tightening torque of fl are pipe connections The operating pressure of R410A
is higher than that of R22 (approx.
1.6 times). It is therefore necessary to fi rmly tighten the fl are pipe connecting sections (which connect the indoor and outdoor units) up to the specifi ed tightening torque. Incorrect connections may cause not only a gas leakage, but also damage to the refrigeration cycle.
1. How to shape the pipes Shape the pipes along the incused line on
the outdoor unit.
2. How to fi t position of the pipes Put the edges of the pipes to the place with
a distance of 85 mm from the incused line.
Shaping pipes
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 result.)
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 25 meters.
(15 minutes for 25 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.
