(2) Raise the handle as far as it will go.
(3) Turn handle clockwise to lock under pin in underside of cap.
(4) Proceed through steps G.2 to G.3, which follow.
b. Multiport rotary valve.
(1) Position valve to "Filter" setting. This is your normal flow from the pump through the filter back to the pool.
(2) Proceed through steps G.2 to G.3, which follow.
2. Follow steps in Section D, System Restart. Your filter is now in full operation. Note the original starting pressure on the gauge.
3. Backwash your filter when pressure reads between 5 to 11 psi over the original starting pressure, see Step G.5. When your
filter builds up pressure from its starting point, then your filter is performing its function. However, this buildup of pressure
will vary because of different bathing loads, temperature, weather conditions, etc.
a. MY ORIGINAL STARTING PRESSURE IS _____ psi (pounds per square inch). I SHOULD BACKWASH AT
_____ psi
Small grains of sand may leave the filter during backwashing or may even appear at the return line when filter is first started
up. This is characteristic of permanent media filters.
Always turn pump off before changing valve positions. CHANGING VALVE POSITIONS WHILE THE PUMP IS RUNNING CAN DAMAGE
THE CONTROL VALVE, AND MAY RESULT IN PERSONAL INJURY OR PROPERTY DAMAGE.
4. Check the system for water leaks. If a leak is found, shut pump off and relieve system pressure, before correcting the leak.
5. As the filter removes dirt and impurities from the pool water, the accumulation will cause the filter pressure to rise and the flow
to diminish. It is time to backwash the filter if you are using 1hp or smaller pump and the pressure gauge reading is 5 to 7 psi
higher than the clean filter reading noted in Step G.3, above. For systems with larger than 1 hp pumps, this pressure rise will be
in the 9 to 11 psi range before it is time to backwash.
To prevent damage to the pump and filter and for proper operation of the system, clean pump strainer and skimmer baskets regularly.
H. FILTER CLEANING - CLEANING FREQUENCY.
1. Cleaning frequency will vary from pool to pool and with other factors such as weather conditions, heavy rains, dust pollen,
bather load, and water chemistry. Check the pressure gauge reading on a regular basis. If you have a 1 HP or smaller pump,
backwash when the pressure gauge reading increases 5 to 7 psi over the initial clean filter reading. With larger pumps,
backwash when the increase is 9 to 11 psi.
2. It is important NOT to backwash the filter solely on a timed basis such as every two days. Backwashing too frequently
actually causes poor filtration.
I. FILTER CLEANING - FILTER BACKWASH PROCEDURE.
1. Since the sand media bed is the key to efficient filtration in this type filter system, that media bed should be visually inspected
at least once each year.
Always turn pump off before changing valve positions. CHANGING VALVE POSITIONS WHILE THE PUMP IS RUNNING CAN DAMAGE
THE CONTROL VALVE, AND MAY RESULT IN PERSONAL INJURY OR PROPERTY DAMAGE.
2. Turn the pump off, shut off any automatic controls to ensure that the system is not inadvertently started during servicing.
3. Open the High Flow™ manual air relief valve and waste drain valve, or plug, if your system has one. Ensure that suction and
backwash lines are open so that water is free to come from the pool and flow out the backwash line.
4. Remove hair and lint pot lid from pump and clean basket. Replace basket, refill hair and lint pot with water, install lid and
clamp securely.
