•Equipment complying with IEC/EN 61000-3-12.
WARNING (Could lead to death, serious injury, etc.)
nDo not install the unit by yourself (user).
Incomplete installation could cause fire or electric shock, injury due to the unit falling, or leakage of water. Consult the dealer from whom you purchased the unit or a qualified installer.
nPerform the installation securely referring to the installation manual.
Incomplete installation could cause fire, electric shock, injury due to the unit falling, or leakage of water.
nWhen installing the unit, use appropriate protective equipment and tools for safety.
Failure to do so could cause injury.
nInstall the unit securely in a place which can bear the weight of the unit.
If the installation location cannot bear the weight of the unit, the unit could fall causing injury.
nElectrical work should be performed by a qualified, experienced electrician, according to the installation manual. Be sure to use an exclusive circuit. Do not connect other electrical appliances to the circuit.
If the capacity of the power circuit is insufficient or there is incomplete electrical work, it could result in a fire or an electric shock.
nDo not damage the wires by applying excessive pressure with parts or screws.
Damaged wires could cause fire or electric shock.
nBe sure to cut off the main power in case of setting up the indoor P.C. board or wiring works.
Failure to do so could cause electric shock.
nUse the specified wires to connect the indoor and outdoor units securely and attach the wires firmly to the terminal block connecting sections so the stress of the wires is not applied to the sections. Do not extend the wires, or use intermediate connection.
Incomplete connecting and securing could cause fire.
nDo not install the unit in a place where inflammable gas may leak.
If gas leaks and accumulates in the area around the unit, it could cause an explosion.
nDo not use intermediate connection of the power cord or the extension cord and do not connect many devices to one AC outlet.
It could cause a fire or an electric shock due to defective contact, defective insulation, exceeding the permissible current, etc.
nBe sure to use the parts provided or specified parts for the installation work.
The use of defective parts could cause an injury or leakage of water due to a fire, an electric shock, the unit falling, etc.
nWhen plugging the power supply plug into the outlet, make sure that there is no dust, clogging, or loose parts in both the outlet and the plug. Make sure that the power supply plug is pushed completely into the outlet.
If there is dust, clogging, or loose parts on the power supply plug or the outlet, it could cause electric shock or fire. If loose parts are found on the power supply plug, replace it.
nAttach the electrical cover to the indoor unit and the service panel to the outdoor unit securely.
If the electrical cover of the indoor unit and/or the service panel of the outdoor unit are not attached securely, it could result in a fire or an electric shock due to dust, water, etc.
nWhen installing, relocating, or servicing the unit, make sure that no substance other than the specified refrigerant (R410A) enters the refrigerant circuit.
Any presence of foreign substance such as air can cause abnormal pressure rise and may result in explosion or injury. The use of any refrigerant other than that specified for the system will cause mechanical failure, system malfunction, or unit breakdown. In the worst case, this could lead to a serious impediment to securing product safety.
nDo not discharge the refrigerant into the atmosphere. If refrigerant leaks during installation, ventilate the room.
If refrigerant comes in contact with a fire, harmful gas could be generated.
Refrigerant leakage may cause suffocation. Provide ventilation in accordance with EN378-1.
nCheck that the refrigerant gas does not leak after installation has been completed.
If refrigerant gas leaks indoors, and comes into contact with the flame of a fan heater, space heater, stove, etc., harmful substances will be generated.
nUse appropriate tools and piping materials for installation.
The pressure of R410A is 1.6 times more than R22. Not using appropriate tools or materials and incomplete installation could cause the pipes to burst or injury.
nWhen pumping down the refrigerant, stop the compressor before disconnecting the refrigerant pipes.
If the refrigerant pipes are disconnected while the compressor is running and the stop valve is open, air could be drawn in and the pressure in the refrigeration cycle could become abnormally high. This could cause the pipes to burst or injury.
nWhen installing the unit, securely connect the refrigerant pipes before starting the compressor.
If the compressor is started before the refrigerant pipes are connected and when the stop valve is open, air could be drawn in and the pressure in the refrigeration cycle could become abnormally high. This could cause the pipes to burst or injury.
nFasten a flare nut with a torque wrench as specified in this manual.
If fastened too tight, a flare nut may break after a long period and cause refrigerant leakage.
nThe unit shall be installed in accordance with national wiring regulations.
nEarth the unit correctly.
Do not connect the earth to a gas pipe, water pipe, lightning rod or telephone earth. Defective earthing could cause electric shock.
CAUTION |
(Could lead to serious injury in particular environments when operated incorrectly.) |
nInstall an earth leakage breaker depending on the installation place.
If an earth leakage breaker is not installed, it could cause electric shock.
nPerform the drainage/piping work securely according to the installation manual.
If there is defect in the drainage/piping work, water could drop from the unit, soaking and damaging household goods.
nDo not touch the air inlet or the aluminum fins of the outdoor unit.
This could cause injury.

5)Leave as it is for one or two minutes. Make sure the pointer of gauge manifold valve remains in the same position. Confirm that pressure gauge shows -0.101 MPa [Gauge] (-760 mmHg).
6)Remove gauge manifold valve quickly from service port of stop valve.
7)Fully open all stop valves on the gas pipe and the liquid pipe. Operating without fully opening lowers the performance and this causes trouble.
8)Refer to 1-2., and charge the prescribed amount of refrigerant if needed. Be sure to charge slowly with liquid refrigerant. Otherwise, composition of the refrigerant in the system may be changed and affect performance of the air conditioner.
9)Tighten cap of service port to obtain the initial status.

When attaching the control valve to the service port, valve core may deform or loosen if excess pressure is applied. This may cause gas leak.
When attaching the control valve to the service port, make sure that the valve core is in closed position, and then tighten part A. Do not tighten part A or turn the body when valve core is in open position.
