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).

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 (see section on Backwashing the Filter).

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. Contact your local pool shop.

CAUTION:  Most filter media contains dust and fine particles that 

must be backwashed from media before filter is set to ‘Filter’.

CAUTION:

Never vacuum while backwashing.
