Device installation
– installation of the valve
Install the valve in the conduit according to the labelling and the sketch below. Use adapter
unions. Threaded connections should be sealed only with Teflon strip. Although the device is
functional in any position, it must not be installed with the actuator facing down.
If the difference in level between system and tank exceeds 3 meters, stop valves or non-return
valves should be installed to prevent severe damage to the actuator and the valve due to
excessive pressure and flow.
As filter medium can be washed out during backwashing and rinsing, we recommend fitting the
drain with a throttle. Otherwise a stuck valve disk can adversely affect the flawless functioning
of the Aquastar. Polluted or grainy filtering media require the use of adequate pre filters.
Important! During a cycle the filter pump motor must be shut off!
The Praher Aquastar Comfort is approved for 6-way valves by Praher Plastics Austria.
Malfunctions can occur with any other valve type as we are unable to guarantee that
these valves match the dimensions of the Praher 6-way valves.
