The pump cycle starts when the starting time point T1 or T2 is reached. The first pump interval
begins after a 5 minute rest phase. The potentially connected blower is deactivated during the
suction operation. In conjunction with back flushing, it is then activated to support back
flushing cleaning process with air.
There is a temporary aeration after every fourth pump interval, followed by a 5 minute rest
phase. Then it is continued forth with the next pump block. The pump cycle is terminated
when all pump intervals have been performed.

The pump cycle can be interrupted by the float switch "BR min –" (when the water level for the
membrane falls below the minimum allowed level) and "CL max +" (when the clear water tank is
full).
Menu 10: Blower times and intervals
The blower run time (Air ON) and blower pause time (Air OFF) can be set within the range of 1 to
15 min. The set blower operation is performed in total aeration mode and interrupted only by
the pump cycle. The aeration always starts with "Air ON" after any adjustments to the time have
been made.
Setting example for various aeration types:
Timed aeration: Air ON/Off = 5 / 10 (5 Minutes aeration, 10 Minutes Pause)
Continuous aeration:
Air ON/OFF = 15 / 0
Deactivated aeration
Air ON/OFF = 0 / 0
