8. Directions for use
This is a control unit for a multiport valve with 6 positions for fully automatic filter backwashing
according to need, i.e. pressure and/or time. A filter pump connection is activated about 20 sec
after the respective position is reached. The dry running design guarantees safe operation.
Additional electrical connections are available:
Backwash position; backwash and rinse position; for series connection of several valves
installed in series; for interruption of a heater or a heat exchanger before cycle start; for a ball
valve during the cycle.
9. Montage
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
works in any position, it should not be mounted actuator down, if possible. 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!
