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.
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.
Warning
■
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.
■
Consult your local dealer regarding what to do in case of
refrigerant leakage. When the unit is to be installed in a small
room, it is necessary to take proper measures so that the
amount of any leaked refrigerant does not exceed the
concentration limit in the event of a leakage. Otherwise, this may
lead to an accident due to oxygen depletion.
■
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, typhoons, or earthquakes.
Improper installation work may result in accidents due to fall of
equipment.
