AFETY CONSIDERATIONS
The precautions listed here are divided into the following four 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.
■
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
■
Earth the unit.
Earthing resistance should be according to local and national
regulations.
Do not connect the earth wire to gas or water pipes,
lightning conductor or telephone earth wire.
Incomplete earthing may cause electric shocks.
■ Gas pipe.
Ignition or explosion may occur if the gas leaks.
■ Water pipe.
Hard vinyl tubes are not effective earths.
■ Lightning conductor or telephone earth wire.
Electric potential may rise abnormally if struck by a lightning
bolt.
■
Install the power wire at least 1 meter away from televisions or
radios to prevent image interference or noise.
(Depending on the radio waves, a distance of 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.
