Assembly
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 EasyII is approved for 6-way valves by Praher Plastica Austria GmbH.
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.
