Loading Sand Media
1. To keep sand out off collector assembly, place plastic sand shield
over top of collector tube before pouring sand into lter (See
diagram below).
2. To support laterals and prevent
lateral breakage during loadings, ll
tank about half full of water before
loading sand.
3. Pour sand into lter, making sure
that the sand is of the correct type
and quantity for the particular lter
model (Refer lter label).
Make sure gasket area on top of tank is free of sand before installing valve.
4. Before installing valve, double-check that the correct quantity of
sand has been loaded.
5. Remove plastic sand loading shield and keep for future use.
Installation of Multi-Port Valve
1. Install o-ring on valve ange; make sure o-ring is clean, and
has no nicks, tears, or scrapes and lubricate with silicon based
lubricant.
2. Make sure tank and valve anges are clean and free of sand; put
valve on top of tank. Vertical pipe of collector assembly inserts into
base of valve.
3. Install clamp; make sure knob is positioned for easy access for
lter maintenance. Valve port labelled “Pump” should point toward
pump.

Hazardous pressure. Clamp will not hold unless it is
seated properly! DO NOT START PUMP until clamp
ends are 1/4” (6mm) apart or less.
4. Tighten clamp knob until clamp ends (under bolt) are 1/4” (6mm)
apart. Tap around outside of clamp with a mallet to help seat
clamp.
5. Connect pipe from pump discharge to valve port labelled “PUMP”;
use union half provided. Assemble union as follows for leak free
operation:
- o-ring and sealing surfaces must be clean.
- Assemble hand tight only (No wrenches).
- NO pipe compound or teon tape on unions.
6. Complete all plumbing connections, using 1 1/2” (P221100 &
P225100) or 2” (P229200 & P233200) pipe to reduce pressure
losses as much as possible.
- Pipe from valve RETURN port to pool return.
- Pipe from valve WASTE port to waste.
- Suction piping from pool to trap inlet on pump.
7. System is ready to start up.

8. If you notice a leak around the clamp area after 15-30 minutes of
running, repeat steps 3-4.
If there are leaks from beneath valve/clamp
area, STOP PUMP, release all pressure by
turning valve handle to ‘waste’, remove clamp
and valve and clean sealing surfaces.

Operation
The lter operator or owner must be provided with this owner’s
manual. This must be read before operation, and followed during
operation.
Incorrectly installed or tested equipment may fail, causing severe
injury or property damage. Read and follow instructions in owner’s
manual when installing and operating equipment. Have a trained
pool professional perform all pressure tests.
Hazardous Pressure. To avoid explosion and possible severe or
fatal injury, lter system pressure must not exceed 40psi (280kPa)
under any circumstances. NEVER test this lter system with
compressed air; never operate system with water temperature
above 350C.
To prevent equipment damage and possible injury, turn pump
OFF before changing valve position.
Do not add chemicals directly into the pool skimmer. Adding
undiluted chemicals may damage equipment and void
warranty.
Multi-Port Valve Settings
12

Startup/Operation
1. Open system valve and make sure pump is lled with water. Make
sure pool water level is 2” (50mm) above bottom of skimmer
opening.
2. With pump OFF, set valve to
‘BACKWASH’ position.
3. Start pump, circulating water through lter to waste.
NOTE: To prevent pump running dry, be sure water level
never drops below bottom of skimmer inlet. Add water to pool
if necessary to keep skimmer ooded while back-washing and
rinsing.
4. Backwash until water runs clear (1-5 minutes)
5. Stop Pump; set valve to
‘RINSE’ position.
6. Start pump; run pump for 1 minute.
Note: for Zelbrite repeat steps 1 through to 6 three times.
7. Stop pump; set valve to ‘FILTER’
Position.
8. Filter is now ready for service.
9. Record clean starting lter pressure gauge reading as a reference.
10. For new pools, backwash once a day until pool water is sparkling
clear. Backwash when pressure gauge shows 5 to 7 psi (35 to
50kPa) higher than clean starting pressure (refer to step 9).
13

Service & Maintenance
Hazardous pressure. Stop pump and release all pressure from
system before working on lter, valve, or clamp.
General: Wash outside of lter with a mild detergent and water. Rinse off
with hose.
DO NOT use solvents to clean lter; solvents may
damage components in system.
Inspect sand/media bed at least once a year to remove foreign material which
has not been back-washed out of the system.
NOTE: When the sand/media bed gets hard and crusty on top, remove all
the old sand/media and replace it with new sand/media. Alternatively, if the
pressure gauge does not return to within 40kPa of clean lter pressure after
back-washing it is time to replace the lter media.
Weekly Pool Equipment Inspection
1. Check pressure during operation. When pressure is 5 to 7 psi (35
to 50 kPa) higher than clean operating pressure, backwash lter
(see instructions under Startup/Operation, page 12).
2. Except during hot weather with heavy skimmer loads, operating
lter 6 to 12 hours per day should be sufcient. Carefully monitor
water chemical balance and follow recommendations of your local
pool professional.
Water Maintenance
Keep water level at least 2” (50mm) above bottom of skimmer opening. Failure
to do so can allow air to enter system, causing pump to lose prime and air
to enter lter.
Maintain pH between 7.2 and 7.6 in pool.
14

To prevent damage to system components, keep water
temperature below 380C at all times.
Vacuum Pool
(Refer cleaner operating manual or consult your local pool professional)
1. Fill vacuum hose by submerging in water from one end to the other.
2. To vacuum, insert hose into skimmer suction manifold or into
vacuum line in pool wall. See instructions provided by the pool
builder or pool manufacturer. Start pump, making sure it is primed
and pumping.
3. After vacuuming, clean pump trap basket to remove accumulated
debris, then check lter pressure gauge. If reading is 5 to 7 psi (35
to 50 kPa) higher than initial operating pressure, backwash lter.
Lower or Drain Pool
1. Turn pump ‘OFF’ ; set valve handle to ‘WASTE’.
2. Use Vaccuum cleaner hose and head.
3. Start pump; run until pool is lowered to desired level.
4. Turn pump ‘OFF’ set valve handle to ‘FILTER’
5. Start pump.
Multi-Port Valve Service
If valve is leaking during normal operation it will need
to be repaired by an authorised Pentair Water service
technician.
Valve Removal
Hazardous pressure. Stop pump and release all pressure
from system before working on lter, valve, or clamp.
