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 affected by impurities such as water and oils because the pressure of R410A refrigerant is approx. 1.6 times of refrigerant R22.
ALSO NEW OILS ARE USED WITH R410A, THUS ALWAYS USE NEW REFRIGERANT PIPING AND DO NOT ALLOW MOISTURE OR DUST TO
ENTER THE SYSTEM.
To avoid mixing refrigerant and refrigerant machine oil, the sizes of charging port on the main unit is different than those used on R22 machines and
different tools will be required.
• EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in equipment damage or improper operation.
Do not bury more than 36 in. (914 mm) of refrigerant pipe in the ground. If any section of pipe is buried, there must be a 6 in. (152 mm) vertical rise to
the valve connections on the outdoor units. If more than the recommended length is buried, refrigerant may migrate to the cooler buried section during
extended periods of system shutdown. This causes refrigerant slugging and could possibly damage the compressor at start-up.
DANGER
• FOR USE BY QUALIFIED PERSONS ONLY.
• 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 THAT THE EARTH WIRE IS NOT BROKEN OR DISCONNECTED BEFORE INSTALLATION.
• DO NOT INSTALL THE UNIT 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 RELOCATING THE AIR CONDITIONER, BE VERY CAREFUL NOT TO MIX THE SPECIFIED REFRIGERANT (R410A) WITH ANY OTHER
GASEOUS BODY INTO THE REFRIGERATION CYCLE. IF AIR OR ANY OTHER GAS IS MIXED WITH 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 OF REFRIGERANT LEAKAGE DURING INSTALLATION, ALLOW FRESH AIR INTO THE ROOM IMMEDIATELY. IF THE
REFRIGERANT GAS IS HEATED BY FIRE OR OTHER MEAN, IT GENERATES POISONOUS GAS.
Installing, staring up, and servicing air-conditioning equipment can be hazardous due to system pressures, electrical components, and equipment location
(roofs, elevated structures, etc.).
Only trained, qualified installers and service mechanics should install, start-up, and service this equipment.

CAUTION
• 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. Report any damages to your distributor.
• 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.
• Please read this installation manual carefully before installing the unit. It contains further important instructions for proper installation.
• 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 flare 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 fins 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 fire.
• 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.
• The manufacturer shall not assume any liability for the damage caused by not observing the description of this manual.
WARNING
• ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury or death.
Main electrical disconnect switch must be in the OFF position before installing, modifying, or servicing the system. There may be more than 1 disconnect
switch. Lock out and tag switch with a suitable warning label.
• Never modify this unit by removing any of the safety guards or bypassing any of the safety interlock switches.
• Installation work must be performed by qualified personnel only.
• Specified 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 specified pipe parts, and ensure correct installation, otherwise
damage and/or injury may be caused. At the same time, water leakage, electrical shock, and fire may occur.
• Be sure to install the unit in a place that can sufficiently 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 trained, qualified installers and service mechanics 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. Insufficient power supply or improper installation
may cause electrical shock or fire.
• Use a cabtyre cable to connect wires in the indoor/outdoor units. Midway connection is not allowed. Improper connection or fixing may cause a fire.
• Wiring between the indoor unit and outdoor units must be well shaped so that the cover can be firmly placed. Improper cover installation may cause
increased heat, fire, or electrical shock at the terminal area.
• Be sure to use only approved accessories or specified parts. Failure to do so may cause the unit to fall, water leakage, fire 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
fire or something else from a fan heater, stove or gas range, it causes generation of poisonous gas.
• Make sure the equipment is properly grounded. Do not connect the ground 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 flammable gas may leak. If there is any gas leakage or accumulation around the unit, it can cause a fire.
• 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 fire.
• Installation work must be performed following the instructions in this installation manual. Improper installation may cause water leakage, electrical shock
or fire. 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 in damage to the unit or injury.
• In a pump-down operation, be sure to stop the compressor unit before removing the refrigerant pipe. If removing the refrigerant pipe while the
compressor is operating with the service valve opened, it may cause air suction and overpressure, resulting in damage to the unit 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 fire or electrical shock.
• If you detect any damage, do not install the unit. Contact your dealer immediately.
• 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.

Evacuating
After the piping has been connected to the indoor unit, you vacuum both
units at once.
Be sure to use a vacuum pump with counter-flow prevention function so
that inside oil of the pump does not flow backward into pipes of the air
conditioner when the pump stops.
(If oil inside of the vacuum pump enters the air conditioner, which uses
R410A, refrigeration cycle trouble may happen.)
1. Connect the charge hose from the manifold valve to the service port of
the packed valve at the gas side.
2. Connect the charge hose to the port of the vacuum pump.
3. Open fully the low pressure side handle of the manifold valve gauge.
4. Operate the vacuum pump to start evacuating. Perform evacuation for
about 15 minutes if the piping length is 66 feet (20 m). (assuming a
pump capacity of 27 liters per minute) Then confirm that the compound
pressure gauge reading is –101 kPa (–76 cmHg).
Using a vacuum pump
Evacuate the air in the connecting pipes and in the indoor unit using a
vacuum pump. Do not re-use the refrigerant in the outdoor unit. For details,
see the vacuum pump manual.
