7. OPERATING INSTRUCTIONS
7.1 Multiport Valve Control
The flow of water through the filter is controlled by the
multiport valve on the top of the filter tank. The handle on
top of the valve can be moved to any one of six positions,
which have the following functions:
Valve Position Function
FILTER Normal filtration and
vacuuming through filter.
BACKWASH Clean the filter.
RINSE Used on initial filter start-up
and after backwash to prevent
dirt in the sand returning to
the pool.
WASTE By-passes the filter; used
for vacuuming to waste, or
draining the pool.
RECIRCULATE By-passes the filter to
circulating water to the pool or
to boost spa jets.
CLOSED Shuts off all flow to the filter.
Do not run pump.
CAUTION Never shift the valve handle
position while the pump is running.
This filter tank must not be operated
under vacuum. Should leaf baskets or
suction lines become clogged, blocked
or closed, filter damage not covered by
guarantee may occur (particularly if an
auxiliary pump is installed in line down
stream of the filter). Never vacuum
while backwashing.
8. NORMAL FILTER CYCLE
1. Set the valve to filter and start the pump.
2. With a clean filter, record the pressure gauge reading
or mark the needle position on the pressure gauge.
3. Operate the filter each day for a sufficient time to turn
over the water in the pool once every day. The filter
should also be operated at all times the pool is in use
and for about one hour afterwards. During the winter,
the running time may be reduced.
4. When the pressure gauge reading is 40 – 50kPa higher
than the clean filter gauge reading as in (2) above, it
will be necessary to clean or backwash the filter (refer
to section 9 - Backwashing the Filter).
9. BACKWASHING THE FILTER
When the filter gauge reading is 40 - 50kPa above the
clean filter gauge reading, cleaning or backwashing is
required. To perform the backwash operation:
1. Shut off the pump. Be sure to disconnect any automatic
vacuum cleaner.
2. Shift the valve handle to backwash.
3. Start the pump and run until the water appears clean
through the sight glass (this will take two or three
minutes).
4. Shut off the pump and turn the valve handle to rinse.
5. Start the pump and run for approximately one minute.
6. Shut off the pump and turn the valve handle to filter.
7. Start the pump; a new filter cycle has now begun.
8. If a backwash cycle does
not reduce the operating
pressure of the filter, the media will need to be
changed.
WARNING - FILTER OPERATES
UNDER HIGH PRESSURE
Ensure all lids / closures / clamps
are correctly secured before operating
the system.
Never adjust clamps or change
valve settings with the system
under pressure.
Relieve all pressure from system
before working on filter.
