FKN74C, FN74C and FN09S
The Z74S automatic reverse rinsing actuator provides fully automatic cleaning for all Honeywell 
Braukmann reverse rinsing filters, filter combinations and water supply units with bayonet connection. 
A bayonet connection enables fitting the Z74S without tools. The reverse rinsing interval is set 
permanently to 45 days. The Z74S automatic reverse rinsing actuator has a safety function which 
prevents the ball valve from opening when the battery voltage is too low and notifies this through an 
acoustic signal for approx. 2 days.
Use reverse rinsing actuator Z74S for filters and filtercombinations HS10S, F76CS, FK76CS, 
FKN76CS, FN76CS, F74C, FK74C, FKN74C, FN74C and FN09S.
