Safety Considerations - Daikin EDLQ036BA6VJU1 Installation Manual

S
CONSIDERATIONS
AFETY
The precautions listed here are divided into the following two types.
Both cover very important topics, so be sure to follow them carefully.
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.
Danger
■
Before touching electric terminal parts, turn off power switch.
■ When service panels are removed, live parts can be easily
touched by accident.
Never leave the unit unattended during installation or servicing
when the service panel is removed.
■ Do not touch water pipes during and immediately after operation
as the pipes may be hot. Your hand may suffer burns. To avoid
injury, give the piping time to return to normal temperature or be
sure to wear proper gloves.
Do not touch any switch with wet fingers. Touching a switch with
■
wet fingers can cause electrical shock.
■ Before touching electrical parts, turn off all applicable power
supply.
Warning
■ Tear apart and throw away plastic packaging bags so that
children will not play with them.
Children playing with plastic bags face danger of death by
suffocation.
■ Safely dispose of packing materials. Packing materials, such as
nails and other metal or wooden parts, may cause stabs or other
injuries.
Ask your dealer or qualified personnel to carry out installation work.
■
Do not 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 lead to 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,
electric shocks, fire, or the unit falling.
■ Install the unit on a foundation that can withstand its weight.
Insufficient strength may result in the fall of equipment and
■
causing injury.
Carry out the specified installation work in consideration of
■
strong winds, hurricanes, or earthquakes.
Improper installation work may result in accidents due to fall of
equipment.

■ Make certain that all electrical work is carried out by qualified
personnel according to the local laws and regulations and this
installation manual, using a separate circuit.
Insufficient capacity of the power supply circuit or improper
electrical construction may lead to electric shocks or fire.
■ Be sure to install a ground fault circuit interrupter according to
local laws and regulations.
Failure to install a ground fault circuit interrupter may cause
electric shocks and fire.
Make sure that all wiring is secure, using the specified wires and
■
ensuring that external forces do not act on the terminal
connections or wires.
Incomplete connection or fixing may cause a fire.
■
When wiring the power supply, form the wires so that the
frontside panel can be securely fastened.
If the frontside panel is not in place, overheat of the terminals,
electric shocks or a fire may be caused.
■
After completing the installation work, check to make sure that
there is no leakage of refrigerant gas.
Never directly touch any accidental leaking refrigerant. This
■
could result in severe wounds caused by frostbite.
■ 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.
■ Do not touch the internal parts (pump, backup heater, etc.)
during and immediately after operation.
Your hands may suffer burns if you touch the internal parts. To
avoid injury, give the internal parts time to return to normal
temperature or, if you must touch them, be sure to wear proper
gloves.
Caution
■ For use of units in applications with temperature alarm settings it
is advised to foresee a delay of 10 minutes for signalling the
alarm in case the alarm temperature is exceeded. The unit may
stop for several minutes during normal operation for "defrosting
of the unit" or when in "thermostat-stop" operation.
■ Ground the unit.
Grounding resistance should be according to local laws and
regulations
Do not connect the ground wire to gas or water pipes,
lightning conductor or telephone ground wire.
Incomplete grounding may cause electric shocks.
■ Gas pipe.
Ignition or explosion may occur if the gas leaks.
■ Water pipe.
Hard vinyl tubes are not effective grounds.
■ Lightning conductor or telephone ground wire.
Electric potential may rise abnormally if struck by a lightning
bolt.
■
Install the power wire at least 3 feet (1 meter) away from
televisions or radios to prevent image interference or noise.
(Depending on the radio waves, a distance of 3 feet (1 meter)
may not be sufficient to eliminate the noise.)
Do not rinse the unit. This may cause electric shocks or fire.
■
■ Do not install the unit in places such as the following:
■ Where there is mist of mineral oil, oil spray or vapour.
Plastic parts may deteriorate, and cause them to fall out or
water to leak.
■ Where corrosive gas, such as sulphurous acid gas, is
produced.
Corrosion of copper pipes or soldered parts may cause the
refrigerant to leak.
