Daikin FXFQ09PVJU Installation Manual page 3

• Safely dispose all packing and transportation materials in accordance with federal/state/local laws or ordi-
nances. Packing materials such as nails and other metal or wood parts, including plastic packing mate-
rials used for transportation may cause injuries or death by suffocation.
WARNING
• Only qualified personnel must carry out the installation work. Installation must be done in accordance with
this installation manual. Improper installation may result in water leakage, electric shock, or fire.
• When installing the unit in a small room, take measures to keep the refrigerant concentration from exceed-
ing allowable safety limits. Excessive refrigerant leaks, in the event of an accident in a closed ambient
space, can lead to oxygen deficiency.
• Use only specified accessories and parts for installation work. Failure to use specified parts may result in
water leakage, electric shocks, fire, or the unit falling.
• Install the air conditioner on a foundation strong enough that it can withstand the weight of the unit. A foun-
dation of insufficient strength may result in the unit falling and causing injuries.
• Take into account strong winds, typhoons, or earthquakes when installing. Improper installation may result
in the unit falling and causing accidents.
• Make sure that a separate power supply circuit is provided for this unit and that all electrical work is carried
out by qualified personnel according to local, state, and national regulations. An insufficient power supply
capacity or improper electrical construction may lead to electric shocks or fire.
• Make sure that all wiring is secured, that specified wires are used, and that no external forces act on the ter-
minal connections or wires. Improper connections or installation may result in fire.
• When wiring, 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 the terminals overheating.
• Before touching electrical parts, turn off the unit.
• Be sure to install a ground fault circuit interrupter if one is not already available. This helps prevent electrical
shocks or fire.
• Securely fasten the outside unit terminal cover (panel). If the terminal cover/panel is not installed properly,
dust or water may enter the outside unit causing fire or electric shock.
• When installing or relocating the system, keep the refrigerant circuit free from substances other than the
specified refrigerant (R410A) such as air. Any presence of air or other foreign substance in the refrigerant
circuit can cause an abnormal pressure rise or rupture, resulting in injury.
• Do not change the setting of the protection devices. If the pressure switch, thermal switch, or other pro-
tection device is shorted and operated forcibly, or parts other than those specified by Daikin are used, fire
or explosion may occur.
CAUTION
• Do not touch the switch with wet fingers. Touching a switch with wet fingers can cause electric shock.
• Do not allow children to play on or around the unit to prevent injury.
• Do not touch the refrigerant pipes during and immediately after operation as the refrigerant pipes may be
hot or cold, depending on the condition of the refrigerant flowing through the refrigerant piping, compressor,
and other refrigerant cycle parts. Your hands may suffer burns or frostbite if you touch the refrigerant pipes.
To avoid injury, give the pipes time to return to normal temperature or, if you must touch them, be sure to
wear proper gloves.
• Heat exchanger fins are sharp enough to cut.
To avoid injury wear glove or cover the fins when working around them.
• Install drain piping to proper drainage. Improper drain piping may result in water leakage and property dam-
age.
• Insulate piping to prevent condensation.
• Be careful when transporting the product.
• Do not turn off the power immediately after stopping operation. Always wait for at least 5 minutes before
turning off the power. Otherwise, water leakage may occur.
• Do not use a charging cylinder. Using a charging cylinder may cause the refrigerant to deteriorate.
