䦟䎃 8-2-1.䎃 Manual washing (Washing press Enter)
Ɣ The Manual Washing function performs a simple washing operation using water from the fresh water inlet before cleaning the sensor.
Ɣ The Manual Washing function flows water from the fresh water inlet into the detection tube in the sensor unit for a preset time period.
(But does not judge whether the detection tube is clean.)
Ɣ Usually, you manually wash the inside of the detection tube and clean the sensor with brush while this function flows water (for a preset time
period), drain the spent water from the detection tube, and use this function again to feed water (for a preset time period) to wash the sensor
and the detection tube.
Ŷ Manual washing procedure
Ɣ Check and make sure the fresh water line is firmly connected to the fresh water inlet.
Ɣ When started, the Manual Washing function opens the fresh water valve, flows water for a preset time period (set by "Manual washing time"),
and then stops.
