• When installing the unit in a small room, take measures so that the refrigerant may not exceed the limiting
concentration in the event of refrigerant leakage.
Contact your dealer for further information. If the refrigerant leaks and exceeds the limiting concentration,
it may lead to oxygen deficiency.
• 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.
• Be sure to use only the specified accessories and parts for installation work.
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.
If a foundation does not have sufficient strength, the equipment may fall and cause injury.
• Carry out the required installation work in consideration of strong winds, typhoons or earthquakes.
If the installation work is not properly carried out, the unit may fall down and cause accidents.
• The electrical work must be carried out by the qualified electrician in accordance with the local laws and
regulations and this installation manual. Make sure to provide a dedicated power supply circuit and never
connect additional wiring to the existing circuit.
An insufficient power supply capacity or improper electrical work may lead to electric shocks or fire.
• 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 or fire.
A high surge current from lightning or other sources may cause damage to the air conditioner.
• Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in electric shocks or fire.
• Be sure to switch off the unit before touching any electrical parts.
Touching a live part may result in electric shock.
• For wiring, use the specified wires and connect and fasten them firmly so that no external force from the
wires may be applied to the terminal connections.
If the wires are not firmly connected and fastened, it may cause heating, fire or the like.
• Wiring for power supply and between the indoor and outdoor units must be properly laid and formed, and
the control box lid must be firmly fastened so that the wiring may not push up the structural parts such as
the lid.
If the lid is improperly fastened, it may cause electric shock or fire.
• 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.
• Do not directly touch refrigerant that has leaked from refrigerant pipes or other areas, as there is a danger
of frostbite.
• Do not use flammable gasses (hairsprays, insecticides etc.) near the unit.
Do not use benzine or thinner to wipe the unit.
It could cause cracking, electric shocks or fire (only for R32 refrigerant).
• Make sure installation, servicing, maintenance and repair comply with instruction from Daikin and with
applicable legislation (for example national gas regulation) and are executed only by authorised persons.
• 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 or R32- based on unit specification. The refrigerant
must not be interchanged).
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.
• If the supply cord is damaged, it must be replaced by the manufacturer, a service agent or similarly qualified
persons in order to avoid a hazard.
