Evolution Aqua K1 MICRO BEAD 20, Инструкция по установке и эксплуатации, Страница: 9 / 24

The K1 Micro Bead Filter is operated by a multi-port
valve. This multi-port valve functions by pushing down
on the handle, turning it and relocating it into one of
the operating positions shown on the multi-port valve
(see figure 7). The valve must always be operated with
the circulating pump switched OFF. The ball valve
positioned below the air blower must be closed when
the pump is running. Below we offer an explanation of
each of the multi-port valve’s functions:
1) FILTER: Incoming water from the pond enters
the MPV at point (A) (see figure 8). The water enters
the vessel at point (D) then flows upwards through
the K1 Micro filter media to the top exit bar (B).
The filtered water is returned through the multi-port
valve at point (C) and back into the pond.
2) BACKWASH: This is the position the multi-port
valve should be in for cleaning the K1 Micro filter
media. With the valve in this position, water flow is
reversed through the filter bed so that the water
flow is directed to the top of the unit (B) and exits
the unit at (D) and goes out to the waste line (E).
3) RINSE: This is the position the multi-port valve
should be in for agitating the K1 Micro filter media.
With the valve in this position, air (supplied by the
air blower) is used to agitate the filter media.
Later on in the cleaning process, water is used to
rinse the K1 Micro and exit to waste (E).
4) WASTE: This is the position the multi-port valve should be in to allow water to by-pass
the filter bed and drain to waste (E). With the multi-port valve in this position, the water
flow is directed straight to waste by-passing the unit. This function can be used to lower the
water level or for vacuuming your pond without soiling the filter.
5) RE-CIRCULATE: This is the position the multi-port valve should be in to allow water
to completely by-pass the filter. With the valve in this position, water is pumped from the
pond to the multi-port valve and directly back to the pond, without flowing through the K1
Micro Bead Filter. This is particularly handy if you are treating your pond.
6) CLOSED: This is the position the multi-port valve should be in for closing all flow to the
filter. This position is not to be used with the pump running.
