DAIKIN AIR CONDITIONER
Safety Precautions (1)
Read the precautions in this manual
This appliance is filled with R32.
carefully before operating the unit.
• 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 follow 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.
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.
• 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 hold 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 the instructions in this installation manual.
Be sure to use a dedicated power supply circuit only. Insufficient power supply 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 overheating 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, do not let any other substances besides R32, such as air, enter the refrigerant circuit.
The presence of air or other foreign matter in the refrigerant circuit causes an abnormal pressure rise, which may result in equipment damage and even injury.
• During installation, attach the refrigerant piping securely before operating the compressor.
If the refrigerant pipes are not attached and the stop valve is
open when the compressor is operated, 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 operating 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 circuit breaker.
Failure to install an earth leakage circuit breaker may result in electric shocks or fire.
• Do not use means to accelerate the defrosting process or to clean, other than those recommended by the manufacturer.
• The appliance must be stored in a room without continuously operating ignition sources (for example: open flames,
an operating gas appliance or an operating electric heater).
• Do not pierce or burn.
• Be aware that refrigerants may not contain an odour.
• The appliance must be installed, operated and stored in a room with a floor area larger than 3.9m .

• Comply with national gas regulations.

CAUTION
• Do not hit or forcefully push the intelligent-eye sensor. This can lead to damage and malfunction.
• Do not place large objects near the sensor. Also keep heating units or humidifiers outside the sensor's detection area.
Safety Precautions (2)
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.

Improper drain piping may result in indoor water leakage and property damage.
• Tighten the flare nut as specified, such as with a torque wrench.
If the flare nut is too tight, it may crack after prolonged use, causing refrigerant leakage.

2.
Drilling a wall hole and installing wall embedded pipe
• For metal frame or metal board walls, be sure to use a wall embedded
pipe and wall hole cover in the feed-through hole to prevent possible heat,
electrical shock, or fire.
• Be sure to caulk the gaps around the pipes with caulking material to
prevent water leakage.
1) Drill a feed-through hole with a 80mm diameter through the wall at a
downward angle toward the outside.
2) Insert a wall embedded pipe into the hole.
3) Insert a wall hole cover into wall pipe.
4) After completing refrigerant piping, wiring, and drain piping, caulk the pipe hole gap with putty.
