Safety Considerations - Daikin EKHWS050B3VJU Manuel D'installation

S
AFETY CONSIDERATIONS
The precautions listed here are divided into the following four types.
They all 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.
Be aware that the domestic hot water temperature can/will be
higher than the user set point for domestic hot water depending
on the selected values of certain field settings (example 2).
Refer to the field settings in the installation manual of the indoor
unit EKHBH/X or outdoor unit EBLQ, EBHQ, EDLQ, EDHQ.
If this high domestic hot water temperature can be a potential
risk for human injuries, a mixing valve (field supply) shall be
installed at the hot water outlet connection of the domestic hot
water tank. This mixing valve shall secure that the hot water
temperature at the hot water tap never rise above a set
maximum value. This maximum allowable hot water temperature
shall be selected according to local laws and regulations.

Caution
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 3.28 ft (1 meter) away from
televisions or radios to prevent image interference or noise.
(Depending on the radio waves, a distance of 3.28 ft (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.
Where there is machinery which emits electromagnetic
waves.
Electromagnetic waves may disturb the control system, and
cause malfunction of the equipment.
Where flammable gases may leak, where carbon fibre or
ignitable dust is suspended in the air or where volatile
flammables, such as thinner or gasoline, are handled.
Such gases may cause a fire.
Where the air contains high levels of salt.
Where voltage fluctuates a lot, such as that in factories.
In vehicles or vessels.
Where acidic or alkaline vapour is present.
