GENERAL INFORMATION

•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.

NEVER test this filter with compressed air.

Do not operate filter at water temperatures above 95°F (35°C).

NEVER operate this filter system at more than the stated pressure

on the filter tank.

INSTALLATION

Installation of filter should only be done by qualified,licensed personnel.

For assembly and fillinginstructions,see page6.

Filter mount must:

•Provide weather and freezing protection.

•Provide space and lighting for easy access for routine maintenance. (See

Figures 1and 2, Table II, Page 4, for space requirements.)

•Be on a reasonably level surface and provide adequate drainage.

•

Be as close to pool as possible to reduce line loss from pipe friction.

Piping:

•

Piping must conform to local/stateplumbing and sanitary codes.

•Use pipe joint sealing compound or teflon tape on all male connections of

metal pipe and fittings (except unions).Use teflon tape or Plasto-Joint Stik

all male connections of plastic pipe and fittings. DONOT use pipe dope on

plastic pipe;it will cause the pipe to crack. Do not use sealant or tape on

unions –assemble them dry and hand tight.

•Do not damage union sealing surfaces and “O” Rings.

•

Support pipe independentlyto prevent strains on filter or valve.

•Use 1-1/2or 2”pipe to reduce pressure losses as much as possible.

NOTICE:Filter may be located away from pool,but for adequate flow larger

pipe may be needed. Checklocal codes when considering remote installation.

•

Fittings restrict flow;for best efficiency use fewest possible fittings

•Keep piping tight and free of leaks:pump suction line leaks may cause trapped

air in filter tankor loss of prime at pump;pump discharge line leaks may show

up as dampness or jets of water.

•When unions are provided,use as follows for leakfree connections:

1.O-Ring and sealing surfaces must be clean.

2.Assemble hand tight only (no wrenches).

3.No pipe compound or teflon tape on unions.

Valves:

•Acheckvalve installed between filter and heater will prevent hot water from

backing up into filter and deforming internal components.

•Use care before assembly not to damage union sealing surfaces or O Ring.

Wastewater:

•Be sure all provisions for waste water disposal meet applicable local,state or

national codes. 100 gallons (379 liters)or more of pool water will be dis-

charged during filter backwashing. Do not discharge where water will cause

flooding or damage.

Filter Setup

Assembly: See Figures 2 through 5 for filter assembly.

Loading Sand Media

1.To keep sand out of collector assembly, place plastic sand shield over top

of collector tube before pouring sand into filter (See Figure 5).

2.To support laterals and prevent lateral breakage during loading, fill tank

about half full of water before loading sand.

3.Pour sand into filter tank. See Page 4, for correct type and quantity of sand

to use.

NOTICE: Make sure gasket area on top of tank is free of sand before in-

stalling valve and clamp.

4.Before installing valve, double-check that correct quantity of sand has

been loaded (see Page 4).

5.Remove plastic sand loading shield and keep for future use.

Valve Installation:

1. Install O-Ring on valve flange; make sure O-Ring is clean, dry, and has

no nicks, tears, or scrapes.

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 labeled “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.

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.

5.If clamp will not pull up to 1/4” (6mm) gap, wait 15-30 minutes and

retighten. Tap clamp gently with mallet to help seat clamp.

6.Connect pipe from pump discharge to valve port labeled “PUMP”; use

union half provided. Assemble union as follows for leakfree operation:

A. O-Ring and sealing surfaces must be clean.

Startup/Operation (See Figure 9)

Hazardous pressure. To avoid explosion and possible

severe or fatal injury, filter system pressure must not exceed stated

filter system with compressed air; never operate system with water

temperature above 95°(35° C).

To prevent equipment damage and possible injury, turn

pump OFF before changing valve position.

NOTICE: Do not add chemicals directly into the pool skimmer. Adding

undiluted chemicals may damage equipment and void warranty.

1. Open system valves and make sure pump is filled with water. Make

sure pool water level is 2” (51mm) above bottom of skimmer open-

ing.

2. With pump OFF, set valve to ‘BACKWASH’ position.

3. Start pump, circulating water backwards through filter to waste. Do

not install pressure gauge until a steady stream of water runs out of

gauge port; then stop pump and install gauge.

NOTICE: To prevent pump from running dry, be sure water level

never drops below bottom of skimmer inlet. Add water to pool if

necessary to keep skimmer flooded while backwashing and rinsing.

4. Backwash until water runs clear (3-5 minutes).

5. Stop pump; set valve to ‘RINSE’ position.

6. Start pump; run pump for one minute.

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. When pool is first filled, backwash once a day until pool water is

sparkling clear. After that, backwash when pressure gauge shows 5 to

7PSI(34.5 to 48 kPa) higher than starting pressure.

1. Install O-Ring

on valve flange.

2. Install valve on tank.

Tank flange must

be clean; insert

MAINTENANCE

General:

• Wash outside of filter with a mild detergent and water. Rinse off with hose.

NOTICE: DO NOT use solvents to clean filter; solvents may damage plastic

components in system.

• Inspect sand bed at least once a year to remove foreign material which has not

been backwashed out of system.

NOTICE: When the sand bed gets hard and crusty on top, remove all the old

sand and replace it with new sand.

Weekly Pool Equipment Inspection:

1. Check pressure during operation. When pressure is 5 to 7 PSI (34.5 to 48

kPa) higher than initial operating pressure, backwash filter (see instructions

under “Startup/Operation”, Page 7).

2. Except during hot weather with heavy swimmer loads, operating filter 6 to 12

hours per day should be sufficient. Carefully monitor water chemical balance

and follow recommendations of your local pool professional.

Water Maintenance

• Keep water level at least 2” (51mm) 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 at 7.2 to 7.6 in pool.

To prevent damage to system components, keep water temperature below

95° F. (35° C) at all times.

Vacuum Pool:

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 pool builder or pool manufac-

turer. Start pump, making sure it is primed and pumping.

3. After vacuuming, clean pump trap to remove accumulated debris, then

check filter pressure gage. If reading is 5 to 7 PSI (34.5 to 48 kPa) higher

than initial operating pressure, backwash filter.

Lower or Drain Pool

1. Turn pump ‘OFF’; set valve handle to ‘WASTE’.

2. Use vacuum 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.

STORAGE/WINTERIZING

Pool chemicals may give off corrosive fumes. Store chemicals

away from system in a well ventilated area.

NOTICE: Allowing water to freeze will damage filter and void warranty. If an-

tifreeze is needed, use propylene glycol; it’s plastic compatible and non-toxic.

Follow manufacturers instructions. Do not use ethylene glycol based anti-

freeze – it’s toxic and it may damage plastic components.

1. Open all system valves. Set multiport valve at ‘WINTERIZE’ to allow air pas-

sage to all ports.

Fig. 10: Valve settings to lower

pool water level. Stop pump

before changing valve position.

Fig. 11: Valve setting for winter

storage. Stop pump before

changing valve position.

2. Remove drain plug from filter.

3. Drain filter tank completely and replace drain cap (Figure 13, Page 10).

4. Cover with plastic or tarpaulin to protect from weather, but do not seal from

air circulation.

5. Protect from freezing.

Startup for Winterized Equipment:

1. Remove any temporary weather protection placed around system for shut-

down.

2. See “Startup”, Page 7, for reactivation of the filter.

3. Inspect all electrical wiring to pump for damage or deterioration over the

shutdown period. Have a qualified serviceman repair/replace wiring as

needed. Inspect and tighten all watertight connections.

4. Open all valves in suction and return piping.

5. Remove any winterizing plugs in system.

6. Drain all winterizing chemicals (if used) from system; flush system.

7. Close all drain valves and replace all drain plugs in system (see Page 10).

8. Fill pool with water to proper level (see pool manufacturer’s instructions).

MULTI-PORT VALVE SERVICE

Hazardous pressure. Stop pump and release all pressure from sys-

tem before working on filter, valve, or clamp. Filter and valve design allows air

to bleed off automatically in normal service. However, always be sure pressure is

off system before working on filter, valve or clamp.

NOTICE: if Multi-Port valve is below pool water level, close suction and dis-

charge valves before disassembly to prevent draining pool.

Handle Replacement:

1. Stop pump.

2. Place handle in ‘FILTER’ position.

3. Remove pin (Key 1, Figures 12A and 12B) to disconnect handle. If it cannot

be removed by hand, use a hammer and center punch and lightly tap it out.

4. Remove handle; replace with a new one. Be sure new handle is in ‘FILTER’

position.

5. Replace pin.

Lid and Plug replacement:

1. Remove Handle (see ‘Handle Replacement’ above).

2. Remove plug:

A. Remove all screws and nuts (Key Nos. 2 and 6, Figures 12A and 12B).

B. Remove lid (Key No. 3) by pulling straight up while holding plug shaft

(Key No. 5) down with thumb.

3. Inspect Internal Parts:

Inspect plug and gasket spring, O-Rings, and internal washers (Key No. 4).

Replace if necessary.

E. Tighten all lid screws to 55 inch-lbs. (63.4 kg-cm) torque.

Valve Removal

Hazardous pressure. Stop pump and release all pressure from sys-

tem before working on filter, valve, or clamp.

NOTICE: If multi-Port Valve is below pool water level, close suction and dis-

charge 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 reinstall valve, follow instructions, Figures 6 and 7, Page 7. BE SURE to

follow clamp tightening instructions.

Drain Fitting Installation/Removal

NOTICE: If pool is above height of filter, first close valves in pump suction and

return lines to prevent draining pool. If there are no shutoff valves installed, dis-

connect suction and return lines and raise ends above pool water level.

1. Installation: See Figure 13.

2. To Drain Filter:

A. Remove drain cap. Lateral tube should remain in place inside drain

opening to prevent sand from draining out.

B. Open union coupling on backwash port of Multi-Port valve. This will

allow air into filter and allow water to drain from filter tank.

C. Replace cap when tank is empty.

3. Removing Sand From Filter:

A. Remove both drain cap and slotted lateral tube (see Figure 13). Sand and

water will drain from tank.

B. To completely flush filter tank of sand, remove top clamp and multiport

valve and flush the inside of the tank with a hose.
