to flush out automatically. Unplug it again after
approximately 30 seconds. (During the flushing

does not entirely disappear).

leave the water purifier to complete a full automatic flush
cycle. Leave the RO 400 to run pourified water into the
reject water outlet for about 10 minutes and then unplug
the appliance.
