Device installation – installation of the valve
Install the valve in the conduit according to the labeling 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 Easy is approved for 6-way valves by Praher. 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.
