Media Filter Owner’s Manual

FILTER APPLICATION  GENERAL INFORMATION

This ﬁlter is designed for use in domestic/residential swimming pool installations with correctly

sanitised fresh or salt chlorinated water. Suitable for use with sand, Zelbrite or glass ﬁlter

media.

1. Locate the ﬁlter system as close to the pool as practical.

2. Place the ﬁlter on a level stable foundation, preferably a concrete pad or paving. Filter

systems loaded with sand and water can exceed 500kg.

3. Position all equipment to provide ease of access for future servicing.

4. Protect the ﬁlter and pump from weather and direct sunlight by ensuring that they are

properly housed.

5. Ensure there is sucient space to provide adequate ventilation to electric pump motor.

6. Clean a new pool as well as possible before ﬁlling pool and operating ﬁlter. Excess dirt and

large particles of foreign matter in the system can cause serious damage to the ﬁlter and

pump.

7. Ensure pump is compatible with ﬁlter speciﬁcations.

8. For below water level installations ensure isolation valves are installed to reduce risk of

ﬂooding.

INSTALLATION / ASSEMBLY OF INTERNAL COMPONENTS

Installation of ﬁlter should be only carried out by qualiﬁed personnel.

Ensure that the under-drain assembly (hub, laterals & tube) are properly assembled & installed

prior to adding ﬁlter media (sand).

1. The ﬁlter internals comprise of a collector hub and eight (8) laterals, which are supplied

packaged seperately with the collector hub and are stored inside the ﬁlter tank prior to

shipment.

2. Carefully inspect the laterals and hub prior to assembly for any visible defects.

3. Please ensure all laterals are hand tight prior to adding media, as they may have loosened

during shipping.

Loading Sand Media

1. To keep sand out o collector assembly, place plastic sand shield

over top of collector tube before pouring sand into ﬁlter (See

diagram below).

2. To support laterals and prevent lateral breakage during loadings,

ﬁll tank about half full of water before loading sand.

3. Pour sand into ﬁlter, making sure that the sand is of the correct

type and quantity for the particular ﬁlter model (Refer ﬁlter 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 ﬂange; 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 ﬂanges 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 ﬁlter maintenance. Valve

port labelled “Pump” should point toward pump.

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.

Media Filter Owner’s Manual

5. Connect pipe from pump discharge to valve port labelled “PUMP”; use union 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 teﬂon tape on unions.

6. Complete all plumbing connections, using 50.8mm (EC-25-50, EC-28-50) 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

The operation and the positions of valve settings are as follows:

Valve Settings Function

Filter Normal ﬁltration and vacuuming; water goes

through ﬁlter to pool.

Waste Lowers pool level or drains pool; water

bypasses ﬁlter, goes to waste.

Closed Shuts o all ﬂow to ﬁlter and pool.

Backwash Reverses ﬂow for cleaning; water goes

through ﬁlter to waste.

Rinse For initial startup cleaning and sand bed

leveling after backwash; water goes through

ﬁlter to waste.

Recirculate Circulates pool water; bypasses ﬁlter.

WARNING: TURN PUMP OFF BEFORE ADJUSTING VALVE

Media Filter Owner’s Manual

START UP

1. Open system valve and make sure pump is ﬁlled 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 ﬁlter 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 ﬂooded 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 ﬁlter 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).

SERVICE & MAINTENANCE

Hazardous pressure. Stop pump and release all pressure from system before working on

ﬁlter, valve, or clamp.

General: Wash outside of ﬁlter with a mild detergent and water. Rinse o with hose.

DO NOT use solvents to clean ﬁlter; 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 ﬁlter

pressure after back-washing it is time to replace the ﬁlter 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 ﬁlter (see instructions under Startup/Operation, page 12).

2. Except during hot weather with heavy skimmer loads, operating ﬁlter 6 to 12 hours per day should be

su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 ﬁlter.

Maintain pH between 7.2 and 7.6 in pool.

9Media Filter Owner’s Manual

To prevent damage to system components, keep water temperature below 38oC 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 ﬁlter pressure

gauge. If reading is 5 to 7 psi (35 to 50 kPa) higher than initial operating pressure, backwash ﬁlter.

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 Maytronics water

service technician.

Valve Removal

Hazardous pressure. Stop pump and release all pressure from system before working on ﬁlter, valve, or

clamp.

NOTE: If Multi-Port Valve is below pool water level, close suction and discharge

valves before disassembly to prevent draining pool.

1. Disconnect piping from pump and pool.

2. Remove clamp.

3. Remove valve from ﬁlter top.

4. To re-install valve, follow instructions, BE SURE to follow clamp tightening instructions.
