Note: At the installation, check the humidifying pan is located far depth and the sensor is down.
Note:
• Lift the sensor before installing the humidifying pan if the sensor is in lower position after maintenance.
• At the time of installation of humidifying pan, check that the pan is set properly and sensor is down in
the pan. The water level alarm lamp (RH PAN) blinks if the sensor is not down completely. In this case,
set the pan again in adequate location.
• Use an alcohol for sterilization when cleaning the sensor, taking care not to stress the lead wire.
• The sensor detects the water level every 30 minutes. In addition, detection is executed after operation of
the outer door. It takes several seconds to detect the water level. Therefore, the water level alarm
lamp may flash a few times after the outer door is closed with the humidifying pan filled sufficiently.
