Safety Considerations
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 properly during the start-up operation.
Instruct the customer how to operate and maintain the unit.
Inform customers that they should store this Installation Man-
ual 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
leakage, electrical shock, fire, or explosion.
Meanings of DANGER, WARNING, CAUTION, and NOTE
symbols:
DANGER
.............. Indicates an imminently hazardous
situation which,if not avoided,
results in death or serious injury.
WARNING
............ Indicates a potentially hazardous sit-
uation which, if not avoided, could
result in death or serious injury.
CAUTION
............. Indicates a potentially hazardous sit-
uation which, if not avoided, may
result in minor or moderate injury. It
may also be sued to alert against
unsafe practices.
NOTE
................... Indicates a situation that may result
in the unit or property-damage-only
accidents.
DANGER
•
Refrigerant gas is heavier air and replaces oxygen. A
massive leak could lead to oxygen depletion, espe-
cially 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 lightning strikes can cause
a severe shock hazard resulting in severe injury or
death.
•
Do not ground units to gas pipes because a gas leak
could result in an explosion which could lead to se-
vere injury or death.
•
If the refrigerant gas leaks during installation, venti-
late the area immediately.
Refrigerant gas may produce toxic gas if it comes in con-
tact with fire such as from a fan, heater, stove or cooking
device. Exposure to this gas can cause severe injury or
death. After completing the installation work, check that
the refrigerant gas does not leak.
•
Do not install the unit in an area where flammable ma-
terials are present due to the risk of explosion result-
ing in serious injury or death.
•
Safely dispose of the packing materials.
•
Children playing with plastic bags face the danger of
death by suffocation.
Tear apart and throw away plastic packaging bags so that
children cannot play with them.
•
Before touching electrical parts, turn off the unit.Se-
curely install the outdoor unit terminal cover (panel).
If the terminal cover (panel) is not installed properly, dust
or water may enter the outdoor unit and fire or electric
shock may result.
•
When installing or relocating the system, be sure to
keep the refrigerant circuit free from substances oth-
er than the specified refrigerant (R-410A), such as air.
Any presence of air or other foreign substance in the
refrigerant circuit causes an abnormal pressure rise or
rupture, resulting in injury.
•
Do not reconstruct or change the settings of the pro-
tection 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.
CAUTION
•
While following the instructions in this installation
manual, install drain piping to ensure proper drain-
age and insulate piping in order to prevent condensa-
tion.
Improper drain piping may result in water leakage and
property damage.
•
Be very careful about product transportation.
•
Do not touch the refrigerant pipes during and imme-
diately after operation.
During and immediately after operation, the refrigerant
pipes may be hot and may be cold, depending on the con-
dition of the refrigerant flowing through the refrigerant pip-
ing, compressor, and other refrigerant cycle parts. Your
hands may suffer burns or frostbite if you touch the refrig-
erant pipes.
•
Do not touch the switch with wet fingers.
Touching a switch with wet fingers can cause electric
shock.
•
Safely dispose of the packing materials.
Packing materials, such as nails and other metal or
wooden parts, may cause stabs or other injuries.
•
Be sure to install an ground leakage breaker.
Failure to install an ground leakage breaker may result in
electric shocks, or fire.
•
Heat exchanger fins are sharp enough to cut.
To avoid injury wear gloves 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 immediately 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.
•
Do not turn off the power immediately after stopping op-
eration.
Always wait at least five minutes before turning off the
power. Otherwise, water leakage and trouble may occur.
