Daikin FDMA125AV16 Installation Manual page 23

READ THESE INSTRUCTIONS CAREFULLY BEFORE INSTALLATION
• This manual classifies the precautions into WARNINGS and CAUTIONS.
Be sure to follow all the precautions below. They are all important for ensuring safety.
� WARNING Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury.
� CAUTION
It may also be used to alert against unsafe practices.
• After the installation is completed, test the air conditioner and check if the air conditioner operates properly.
Give the user adequate instructions concerning the use and cleaning of the indoor unit according to the operation manual.
In particular, make sure to explain with regard to "SAFETY PRECAUTIONS" and "Not malfunction of the air conditioner''.
Ask the user to keep this manual and the operation manual together in a handy place for future reference.
• This air conditioner comes under the term "appliances not accessible to the general public".
• Ask your local dealer or qualified personnel to carry out installation work.
Improper installation may result in water leakage, electric shocks or a fire.
• Perform installation work in accordance with this installation manual.
Improper installation may result in water leakage, electric shocks or a fire.
• Consult your local dealer regarding what to do in case of refrigerant leakage.
When the indoor unit is installed in a small room, it is necessary to take proper measures so that the amount of any leaked refrigerant
does not exceed the concentration limit in the event of a leakage. Otherwise, this may lead to an accident due to oxygen deficiency.
• Be sure to use only the specified parts and accessories for installation work.
Failure to use the specified parts may result in the air conditioner fall down, water leakage.electric shocks, a fire, etc.
• Install the air conditioner on a foundation that can withstand its mass.
Insufficient strength may result in the air conditioner fall down and causing injury.
• Carry out the specified installation work in consideration of strong winds, typhoons, or earthquakes.
Improper installation may result in an accident such as the air conditioner fall down.
• Make certain that all electric work is carried out by qualified personnel according to the applicable legislation
(note 1) and this installation manual, using a separate circuit. In addition, even if the wiring is short, make sure to use a wiring
that has sufficient length and never connect additional wiring to make the length sufficient. Insufficient capacity of the power
supply circuit or improper electric construction may lead to electric shocks or a fire.
(note 1) Applicable legislation means "All international, national and local directives, laws, regulations and/or codes which are
relevant and applicable for a certain product or domain."
• Earth the air conditioner.
Do not connect the earth wiring to gas or water piping, lightning conductor or telephone earth wiring.
Incomplete earthing may cause electric shocks or a fire.
• Be sure to install an earth leakage circuit breaker.
Failure to do so may cause electric shocks or a fire.
• The appliance must be stored in a room without continuosly operating ignition sources
(for example : open flames, an operating gas appliance or an operating electric heater).
• Do not pierce or burn.
• Be aware that refrigerant may not contain an odor.
• Comply with national gas regulations.
• Be sure to switch off the unit before touching any electrical parts.
Touching a live part may result in electric shocks.
• Make sure that all wiring is secure, using the specified wiring and ensuring that external forces do not act on the terminal
connections or wiring. Incomplete connection or fixing may cause overheating terminals or fire.
• When wiring between the outdoor and indoor units, and wiring the power supply, from the wiring orderly so that the structural
parts such as a cover can be securely fastened.
If the cover is not in place, electric shocks or a fire may be caused.
• Do not add wiring. It may result in heat generation. Electric shocks or fire.
• 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 (R32).
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 refrigerant gas leaks during installation work, ventilate the area immediately.
Toxic gas may be produced if refrigerant gas comes into contact with a fire.
• After completing the installation work, check to make sure that there is no leakage of refrigerant gas.
Toxic gas may be produced if refrigerant gas leaks into the room and comes into contact with a source of a fire, such as a fan
heater, stove or cooker.
• Never directly touch any accidental leaking refrigerant. This could result in severe wounds caused by frostbite.
• Do not stand on the outdoor unit or put things on it.
The unit may fall down or drop, and cause accidents.
• Do not charge any refrigerant into the refrigeration cycle other than the designated refrigerant.
It may cause over pressure in the refrigeration cycle and result in explosion, fire, and injury.
• Do not extend wiring on the way.
It may cause heat generation, electric shocks or fire.
• At the installation work, install the refrigerant piping firmly before operating the compressor.
If the compressor is operated without installing firmly and the service valve is in open condition, it sucks the air, etc.,
and the pressure inside the refrigerant circuit becomes abnormally high. It may cause injury and property damaged.
• At pump down work, stop the compressor before removing the refrigerant piping.
If removing the refrigerant piping when the compressor is operated with its service valve in open condition, it sucks the air,etc.,
and the pressure inside the refrigerant circle become abnormally high, which may cause injury and property damage.
• The appliance shall be installed operated and stored in a room with floor area larger than 3.68 m
• When flared joints are reused, the flare part shall be re-fabricated.
