Safety Considerations - Daikin RXYQ72TAYCU Manual De Instalación

Safety considerations

Read these Safety considerations for Installation carefully be-
fore installing an air conditioner or heat pump. After complet-
ing the installation, make sure that the unit operates properly
during the startup operation.
Instruct the customer on how to operate and maintain the
unit.
Inform customers that they should store this Installation
Manual with the Operation Manual for future reference.
Always use a licensed installer or contractor to install this
product.
Improper installation can result in water or refrigerant leak-
age, electrical shock, fire, or explosion.
Meanings of DANGER, WARNING, CAUTION, and NOTE
Symbols:
DANGER . . . . . . . . Indicates an imminently hazardous
situation which, if not avoided, will
result in death or serious injury.
WARNING . . . . . . . Indicates a potentially hazardous
situation which, if not avoided,
could result in death or serious
injury.
CAUTION . . . . . . . . Indicates a potentially hazardous
situation which, if not avoided,
may result in minor or moderate
injury. It may also be used to alert
against unsafe practices.
NOTE . . . . . . . . . . . Indicates situations that may result
in equipment or property-damage
accidents only.
INFORMATION . . . This symbol identifies useful tips
or additional information.
DANGER
• Refrigerant gas is heavier than air and replaces oxygen. A
massive leak will result in oxygen depletion, especially in
basements, and an asphyxiation hazard will result in seri-
ous injury or death.
• Do not ground units to water pipes, gas pipes, telephone
wires, or lightning rods as incomplete grounding will result
a severe shock hazard resulting in severe injury or death.
Additionally, grounding to gas pipes will result a gas leak
and potential explosion resulting in severe injury or death.
• If refrigerant gas leaks during installation, ventilate the
area immediately. Refrigerant gas will result in producing
toxic gas if it comes into contact with fire. Exposure to this
gas will result in severe injury or death.
• After completing the installation work, check that the re-
frigerant gas does not leak throughout the system.
• Do not install unit in an area where flammable materials
are present due to risk of explosions that will result in seri-
ous injury or death.
• Safely dispose all packing and transportation materials
in accordance with federal/state/local laws or ordinances.
Packing materials such as nails and other metal or wood
parts, including plastic packing materials used for trans-
portation will result in 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 could result in
water leakage, electric shock, or fire.
• When installing the unit in a small room, take measures to
keep the refrigerant concentration from exceeding allow-
able safety limits. Excessive refrigerant leaks, in the event
of an accident in a closed ambient space, could result in
oxygen deficiency.
• Use only specified accessories and parts for installation
work. Failure to use specified parts could result in water
leakage, electric shocks, fire, or the unit falling.
• Install the air conditioner or heat pump on a foundation
strong enough that it can withstand the weight of the unit.
A foundation of insufficient strength could result in the unit
falling and causing injuries.
• Take into account strong winds, typhoons, or earthquakes
when installing. Improper installation could result in the
unit falling and causing accidents.
• Make sure that a separate power supply circuit is pro-
vided 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 could result in electric
shocks or fire.
• Make sure that all wiring is secured, that specified wires
are used, and that no external forces act on the terminal
connections or wires. Improper connections or installation
could result in fire.
• When wiring, position the wires so that the control box
cover can be securely fastened. Improper positioning of
the control box cover could result in electric shocks, fire, or
the terminals overheating.
• Before touching electrical parts, turn off the unit.
• The circuit must be protected with the required safety de-
vice according to local and national regulations,i.e.a fuse,
a circuit breaker or GFCI.
• This equipment can be installed with a Ground-Fault Cir-
cuit Interrupter (GFCI). Although this is a recognized mea-
sure for additional protection, with the grounding system in
North America, a dedicated GFCI is not necessary.
• Securely fasten the unit terminal cover (panel). If the
terminal cover/panel is not installed properly, dust or
water may enter the outdoor unit and could result in fire or
electric shock.
• When installing or relocating the system, keep the refriger-
ant circuit free from substances other than the specified
refrigerant (R410A) such as air. Any presence of air or oth-
er foreign substance in the refrigerant circuit could result
in 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 protection device
is shorted and operated forcibly, or parts other than those
specified by Daikin are used, fire or explosion could result.
