Please read these “SAFETY CONSIDERATIONS” carefully before
installing air conditioning equipment and be sure to install it correctly.
After completing the installation, make sure that the unit operates prop-
erly during the start-up operation.
Please instruct the customer on how to operate the unit and keep it
maintained.
Also, inform customers that they should store this installation manual
along with the operation manual for future reference.
This air conditioner comes under the term “appliances not accessible to
the general public”.
1. SAFETY CONSIDERATIONS
Meaning of danger, warning, caution and note symbols.
DANGER
.................. Indicates an imminently hazardous situa-
tion 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 sued to
alert against unsafe practices.
NOTE
........................ Indicates situation that may result in equip-
ment or property-damage-only accidents.
DANGER
•
Refrigerant gas in heavier air and replaces oxygen. A massive leak
could lead to oxygen depletion, especially in basements, and an
asphyxiation hazard could occur leading to serious injury or death.
•
Do not ground units to water pipes, telephone wires or lightning
rods because incomplete grounding could cause a severe
shock hazard resulting in severe injury or death, and to gas
pipes because a gas leak could result in an explosion which
could lead to severe injury or death.
•
Do not install unit in an area where flammable materials are present
due to risk of explosion resulting in serious injury or death.
•
If the refrigerant gas leaks during installation, ventilate the area
immediately.
Refrigerant gas may produce toxic gas if it comes in contact with fire
such as from a fan, heater, stove or cooking device. Exposure to this
gas could cause severe injury or death.
•
After completing the installation work, check that the refriger-
ant gas does not leak.
Refrigerant gas may produce toxic gas if it comes in contact with fire
such as from a fan, heater, stove or cooking device. Exposure to this
gas could cause severe injury or death.
•
Safely dispose of the packing materials.
Packing materials, such as nails and other metal or wooden parts,
may cause stabs or other injuries.
Tear apart and throw away plastic packaging bags so that children
will not play with them. Children playing with plastic bags face the
danger of death by suffocation.
WARNING
•
Ask your dealer or qualified personnel to carry out installation
work. Do not try to install the machine by yourself.
Improper installation may result in water leakage, electric shocks or fire.
•
Perform installation work in accordance with 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 water leakage, elec-
tric shocks, fire or the unit falling.
•
Install the air conditioner on a foundation strong enough to
withstand the weight of the unit.
A foundation of insufficient strength may result in the equipment fall-
ing and causing injuries.
•
Carry out the specified installation work after taking account of
strong winds, typhoons or earthquakes.
Improper installation work may result in the equipment 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 laws, regulations and this installa-
tion manual.
An insufficient power supply capacity or improper electrical construc-
tion may lead to electric shocks or fire.
•
Make sure that all wiring is secured, the specified wires are
used, and no external forces act on the terminal connections or
wires.
Improper connections or installation may result in fire.
•
When wiring the power supply and connecting the remote con-
troller wiring and transmission wiring, position the wires so
that the electric parts box lid can be securely fastened.
Improper positioning of the electric parts box lid may result in electric
shocks, fire or the terminals overheating.
•
Before touching electrical parts, turn off the power.
•
When installing or relocating the system, be sure to 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 cir-
cuit causes an abnormal pressure rise or rupture, resulting in injury.
•
Do not reconstruct or change the settings 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 may result.
•
Do not touch the switch with wet fingers.
Touching a switch with wet fingers can cause electric shock.
•
Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in electric
shocks, or fire.
•
Heat exchanger fins are sharp enough to cut.
To avoid injury wear glove or cover the fins when working around them.
•
Do not allow children to play on or around the unit as they could
be injured.
•
Refrigerant pipes may be very hot or very cold during or imme-
diately after operation.
Touching them could result in burns or frostbite. To avoid injury give
the pipes time to return to normal temperature or, if you must touch
them, be sure to wear proper gloves
