Filter By-Pass
The pool is often overfilled by rain and to
return it to it’s normal level proceed as
follows:
1. Switch pump OFF.
2. Set multifunction valve to WASTE
position.
3. Switch pump ON. The excess water is
discharged to waste.
4. Switch pump OFF.
5. Set multifunction valve to FILTER
position.
6. Switch pump ON. Filter is now operating
normally.
Recirculate
With
multifunction
valve
set
in
RECIRCULATE position the pool or spa
water is recirculated via the pump only
without passing through the filter. This
condition can be useful to provide extra flow
for boosting spa jets or providing added
circulation for heating.
Valve Closed
The pump must be switched OFF when
multifunction valve is in CLOSED position.
This setting is used to prevent the filter
contents draining back through the pump
when pump lid is removed to enable
cleaning of the hair and lint pot basket.
Backwashing
1. Switch the pump OFF.
2. Select BACKWASH position on multi-
function valve.
3. Switch pump ON - the pool water will
now pass through the filter septums in
the reverse direction which will flush
the unwanted sludge and diatomaceous
earth to waste.
4. Observe water clarity in valve sight
glass and when clear switch pump
OFF.
5. Return valve to FILTER position and
switch pump ON for approximately
20 seconds.
6. Repeat steps 1, 2, 3, 4 and 5 at least
six times until sight glass remains
clear.
7. Return valve to FILTER position and
switch pump ON.
8. Open air release valve.
9. Repeat STARTING THE FILTER par
5 to 10.
Important: Before and after backwashing
check that pool water level is correct.
