If the multiport backwash valve has a "Rinse"

position do the following:

a. Set the selector handle in "Rinse" position.

b. Start the pump and run for one minute. This

helps settle the sand bed.

c. Stop the pump

Set backwash valve handle to normal operation

position or to the "Filter" position if a multiport

backwash valve is installed. If there is a slide

valve, turn handle to unlock and pull fully upwards

to normal filter position.

Make certain all inlet and return lines to the pool

are open to allow free movement of water from the

pool and returning to the pool.

10. Completely open the air release valve on the

gauge/air release assembly by turning the knob on

the back of the assembly fully counterclockwise.

Do not remove the knob.

11. Stand clear of the filter and start the pump. When a

steady stream of water starts to come out of the air

release valve, close the valve.

12. Ensure that water is returning to the pool. The

system is now in normal filtration mode.

13. After the pressure gauge has stabilized, compare

the pressure reading to the original startup "Clean"

pressure noted from the initial installation of the

product. If the pressure gauge after the backwash

procedure indicates more than 5 psi difference

above that reading, it will be necessary to

chemically clean the sand bed. See Section 5.3,

"Chemical Cleaning Procedure".

5.2 Optimal Filter Performance

Determine the need to backwash your filter by

waiting for a 10-12 psi increase above the "Clean" filter

pressure, or by determining that there is a 30% reduction

in flow compared to a 'Clean" filter condition. It is not

recommended to backwash the filter on a timed basis,

e.g. once a month. Pool, weather, dust conditions and

pool occupancy all affect the frequency of the need to

backwash.

NOTE Backwashing a ﬁ lter too often will actually

diminish the ﬁ lter performance by limiting its

ability to catch ﬁ ner particles.

continually for 24 hours, day after day. Allowing the

filter to stop periodically will allow slight disturbance

of the "mud-deck" at the surface of the sand bed, which

will lower the running pressure slightly after rest, and

lengthen the time between backwashing without any

decrease in filtration performance.

5.3 Chemical Cleaning Procedure

deposits and rust from the sand bed with a 12 hour over-

night soaking when used according to the following

instruction. Follow these instructions carefully. Do not

allow the cleaning solution to be pumped back into

the pool.

10. Turn the pump on and pour the cleaning

11. Replace the lid on the pump.

For the best filtration, do not run your system

Sand filter chemical cleaners remove oils,

Use an approved cleaner for sand filters. Approved

cleaners should be readily available through your

pool chemical retail store, or pool maintenance

service or supplier.

Mix the proper solution per the manufacturer's

label instructions.

Backwash the filter per Section 5.1, "Filter

Cleaning Instructions".

Shut the pump off.

If the filter is installed below the pool water level,

close the appropriate isolation valve(s) to prevent

the pool from draining.

With the pump off and automatic controls

disabled, remove filter water drain cap (center

threaded cap on drain fitting) and drain water from

filter.

After filter has drained, replace cap on drain

fitting.

Place the backwash valve in "Backwash" position.

Make certain backwash lines are open.

Remove the strainer pot lid from the filter pump.
