CONSIDERATIONS

 

The precautions listed here are divided into the following two types.
Both cover very important topics, so be sure to follow them carefully.

 

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.

 

 

When a unit is installed in a small room, it is necessary to take
measures so that the leaked refrigerant amount does not
exceed the limit even if it leaks. As for the measures to prevent
the leak from not exceeding the limit, please consult with your
distributor.
If the leaked amount exceeds the limit, it may cause an oxygen
deficiency accident.

 

 

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 air conditioner on a foundation that can withstand its
weight.
Insufficient strength may result in the fall of equipment and
causing injury.
