Troubleshooting
Correct the INSTALLATION posi-
tion to avoid obstruction of air
intake and outlet.
Check the INSTALLA-
TION site (air intake
and outlet obstruction).
If too much gas has been

then recharge the prescribed
mass.
Check the supply
Make sure the supply voltage is
voltage (230V) during
correct (230V).

Check the supply
Make sure the supply voltage is
voltage (400V) during
correct (400V).
