Be sure to close the frontside panel before operation, as not
doing so can cause electric shock.
- The refrigerant pressure may not rise, even if the shut-off
valve is opened after an air purge is performed using a
vacuum pump.
This is because the indoor unit refrigerant piping is closed off
with electric valves inside. This will not create any problems
during operation.
2 To protect the compressor, make sure to turn on the power
supply 6 hours before starting operation.
Test operation from remote controller
1 Be sure to set it to cooling and press the operation switch.

Items to check
Is the wiring as mentioned on the wiring
diagram?
Make sure no wiring has been forgotten
and that there are no missing phases or
reverse phases.
Is the unit properly grounded?
Are any of the wiring attachment screws
loose?
Is the insulation resistance at least 2 MΩ?
- Use a 500 V mega-tester when
measuring insulation.
- Do not use a mega-tester for circuits
which are not 230 V.
Is the size of the piping appropriate?
Is the insulation material for the piping
attached securely?
Are both the liquid and gas pipes
insulated?
Are the shut-off valves for both the liquid
side and the gas side open?
Did you write down the extra refrigerant
and the refrigerant piping length?
