Check point 2. Error release condition
Power on again.
• If the power is not turned on again, the error will not be cleared even if the gas concentration
drops.
• If the refrigerant leakage is detected again after the power is turned on again, an error will occur
again.
• Replace the refrigerant leakage sensor as it will not recover if exposed to a high concentration
of gas or if exposed multiple times even if the concentration is not high.
