Explanation of Events
Stage 1
On pressing the green ‘START’ button the ‘SYSTEM PURGING’ light will illuminate to
indicate that standing water in the UV/03, Carbon Filter and both Sediment Filters is being
replaced with fresh water. Purging of these filters prepares them for use. This process takes
four minutes to complete. At this stage the machine is in open flow and rejected water will be
observed flowing to drain.
Stage 2
After four minutes the ‘SYSTEM PURGING’ light will extinguish and the ‘SYSTEM
FLUSHINGING’ light illuminates. If fitted, the mains electric boost pump will start and system
pressure will increase on the gauge. During this stage both RO filters are being flushed, for a
period of two minutes pure water production is directed to drain. This two minute RO flushing
cycle is repeated once every hour until the tank is full.
