● When the gas concentration returns to the normal level, the ALARM LED (Red) turns off , the OPERATION LED (Green) turns on,
and the buzzer stops sounding. Even when the gas concentration returns to the normal level, the sensor unit alarm operations
indicated above for the Ext output, remote controller, and outdoor unit will continue.
● When the gas concentration returns to the normal level, mixing operation ceases a certain amount of time later.
● If the buzzer was stopped with the switch, the buzzer sounds again after 1 hour if refrigerant is still detected.
● Also replace the sensor PCB with a new one after an alarm occurs notifying of a refrigerant leakage. The sensor is less responsive
to refrigerant after it has detected a high concentration of refrigerant once.
● The recommended period of use for the sensor PCB is 10 years. （ When the unit is used by observing the"Safety Precautions"
correctly and continuously)
● When the service life is exceeded, contact the manager of the facility and the person responsible for servicing to have the sensor
PCB replaced.

When you restart using the remote controller, the error on the remote controller disappears, then operation becomes possible
when the "
" is blinking on the screen.
● When a gas alarm occurs, immediately ventilate the area and
evacuate from the room. Also contact the manager of the
facility and the person responsible for servicing.
● If there is abnormal behaviour, contact the manager of the
facility and the person responsible for servicing.This sensor unit
may be in a state where it is unable to detect refrigerant.
