Disposal requirements
Your product and the batteries supplied with the controller are marked with this symbol.
This symbol means that electrical and electronic products and batteries shall not be mixed
with unsorted household waste. For batteries, a chemical symbol can be printed beneath
the symbol. This chemical symbol means that the battery contains a heavy metal above
a certain concentration. Possible chemical symbols are:
■ Pb: lead (>0.004%)
Do not try to dismantle the system yourself: the dismantling of the product, treatment of the refrigerant,
of oil and of other parts must be done by a qualified installer in accordance with relevant local and national
legislation. Units and waste batteries must be treated at a specialized treatment facility for re-use,
recycling and recovery. By ensuring correct disposal, you will help to prevent potential negative
consequences for the environment and human health. Please contact the installer or local authority
for more information.

Safety Precautions
• The precautions described herein are classified as WARNING and CAUTION. They both contain important information
regarding safety. Be sure to observe all precautions without fail.
• Meaning of WARNING and CAUTION notices
WARNING ..........Failure to follow these instructions properly may result in personal injury or loss of life.
CAUTION ...........Failure to observe these instructions properly may result in property damage or personal injury,
which may be serious depending on the circumstances.
• The safety marks shown in this manual have the following meanings:
Be sure to follow the instructions.
Be sure to establish an earth connection.
Never attempt.
• After completing installation, conduct a trial operation to check for faults and explain to the customer how to operate
the air conditioner and take care of it with the aid of the operation manual.
• The English text is the original instruction. Other languages are translations of the original instructions.
WARNING
• Ask your dealer or qualified personnel to carry out installation work.
Do not attempt to install the air conditioner yourself. Improper installation may result in water leakage, electric shocks or fire.
• Install the air conditioner in accordance with the instructions in this installation manual.
Improper installation may result in water leakage, electric shocks or fire.
Failure to use the specified parts may result in the unit falling, water leakage, electric shocks or fire.
• Install the air conditioner on a foundation strong enough to withstand the weight of the unit.
A foundation of insufficient strength may result in the equipment falling and causing injury.
• Electrical work must be performed in accordance with relevant local and national regulations and with instructions
in this installation manual. Be sure to use a dedicated power supply circuit only.
Insufficiency of power circuit capacity and improper workmanship may result in electric shocks or fire.
• Use a cable of suitable length.
Do not use tapped wires or an extension lead, as this may cause overheating, electric shocks or fire.
• Make sure that all wiring is secured, the specified wires are used, and that there is no strain on the terminal
connections or wires.
Improper connections or securing of wires may result in abnormal heat build-up or fire.
• When wiring the power supply and connecting the wiring between the indoor and outdoor units, position the wires
so that the control box lid can be securely fastened.
Improper positioning of the control box lid may result in electric shocks, fire or over heating terminals.
• If refrigerant gas leaks during installation, ventilate the area immediately.
Toxic gas may be produced if the refrigerant comes into contact with fire.
• After completing installation, check for refrigerant gas leakage.
Toxic gas may be produced if the refrigerant gas leaks into the room and comes into contact with a source of fire, such as a fan heater,
stove or cooker.
• When installing or relocating the air conditioner, be sure to bleed the refrigerant circuit to ensure it is free of air,
and use only the specified refrigerant (R410A).
The presence of air or other foreign matter in the refrigerant circuit causes abnormal pressure rise, which may result in equipment damage and even
injury.
• During installation, attach the refrigerant piping securely before running the compressor.
If the compressor is not attached and the stop valve is open when the compressor is run, air will be sucked in, causing abnormal pressure in the
refrigeration cycle, which may result in equipment damage and even injury.
• During pump-down, stop the compressor before removing the refrigerant piping.
If the compressor is still running and the stop valve is open during pump-down, air will be sucked in when the refrigerant piping is removed,
causing abnormal pressure in the refrigeration cycle, which may result in equipment damage and even injury.
• Be sure to earth the air conditioner.
Do not earth the unit to a utility pipe, lightning conductor or telephone earth lead. Imperfect earthing may result in electric shocks.
• Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in electric shocks or fire.
• Do not touch any electronic component or terminal when the machine is running, stopping or has been powered off
for less than 30 minutes to prevent the risk of electric shock!
1
English
• Be sure to use only the specified accessories and parts for installation work.
CAUTION
• Do not install the air conditioner at any place where there is a danger of flammable gas leakage.
In the event of a gas leakage, build-up of gas near the air conditioner may cause a fire to break out.
• While following the instructions in this installation manual, install drain piping to ensure proper drainage and insulate
piping to prevent condensation.
Improper drain piping may result in indoor water leakage and property damage.
• Tighten the flare nut according to the specified method such as with a torque wrench.
If the flare nut is too tight, it may crack after prolonged use, causing refrigerant leakage.
• Make sure to provide for adequate measures in order to prevent that the outdoor unit be used as a shelter by small animals.
Small animals making contact with electrical parts can cause malfunctions, smoke or fire. Please instruct the customer to keep the area around the
unit clean.
• This appliance is intended to be used by expert or trained users in shops, in light industry and on farms,
or for commercial and household use by lay persons.
• Sound pressure level is less than 70 dB(A).
• NOTE: Motor ground only applies to the iron shell motor.
English
• This appliance is not intended for use by persons, including children, with reduced physical, sensory or mental
capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning
use of the appliance by a person responsible for their safety.
Children shall be supervised to ensure that they do not play with the appliance.

● When the length of connection pipe is above 10m, add refrigerant according to
the extra length of liquid pipe. The additional refrigerant charging amount per
meter is different according to the diameter of liquid pipe. See the following
sheet.
