  When installing the unit, use appropriate protective 

equipment and tools for safety.

 

Failure to do so could cause injury.

  Install the unit securely in a place which can bear the 

weight of the unit.

  If the installation location cannot bear the weight of the 

unit, the unit could fall causing injury.

If gas leaks and accumulates in the area around the unit, 
it could cause an explosion.

■ 

When plugging the power supply plug into the outlet, 
make sure that there is no dust, clogging, or loose 
parts in both the outlet and the plug. Make sure that 
the power supply plug is pushed completely into the 
outlet.

  If there is dust, clogging, or loose parts on the power 

supply plug or the outlet, it could cause electric shock or

Attach the electrical cover to the indoor unit and the 
service panel to the outdoor unit securely.

 

If the electrical cover of the indoor unit and/or the service 
panel of the outdoor unit are not attached securely, it could

refrigerant (R32) enters the refrigerant circuit.

 

Any presence of foreign substance such as air can cause 
abnormal pressure rise and may result in explosion or 
injury. The use of any refrigerant other than that speci-

malfunction, or unit breakdown. In the worst case, this 
could lead to a serious impediment to securing product 
safety.

■ 

Do not discharge the refrigerant into the atmosphere. 
If refrigerant leaks during installation, ventilate the 
room. Check that the refrigerant does not leak after 
installation has been completed.

ing part of such a fan heater, kerosene heater, or cooking 
stove, it will create harmful gas.

■ 

Use appropriate tools and piping materials for instal-
lation.

 

The pressure of R32 is 1.6 times more than R22. Not using 
appropriate tools or materials and incomplete installation 
could cause the pipes to burst or injury. 

■ 

When pumping down the refrigerant, stop the com-
pressor before disconnecting the refrigerant pipes.

  If the refrigerant pipes are disconnected while the com-

pressor is running and the stop valve is open, air could be 
drawn in and the pressure in the refrigeration cycle could 
become abnormally high. This could cause the pipes to 
burst or injury.

■ 

When installing the unit, securely connect the refriger-
ant pipes before starting the compressor.

 

If the compressor is started before the refrigerant pipes are 
connected and when the stop valve is open, air could be 
drawn in and the pressure in the refrigeration cycle could 
become abnormally high. This could cause the pipes to 
burst or injury.
