azardous pressure. If filter is improperly disassembled or -

assembled, it will explode under pressure. To avoid danger of severe injury

r major property damage, always follow service instructions in this manual

o (Pages 8 to 10) when working on filter.

Risk of explosion. Never operate this filter system at more than

50 pounds per square inch (50 PSI/345kPa) pressure!

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.

With a cartridge filter system in place and operating correctly, clean water is returned to the pool faster than the pool water is being contaminated. A typical pool installation will require approximately one week to obtain and maintain the sparkle that your filter is capable of giving you.

Keep pool water pH at recommended level (7.2 to 7.6).

Be sure both clamps are in place and knobs are securely tightened before starting filter.

Maintain pressure gauge in good working order. Replace gauge if it fails or is damaged.

Make sure internal air bleed tube and air bleed filter (Key Nos. 13 and 14, Page 14) are in place before operating filter. Clean air bleed periodically.

Cleaning interval is based on pressure differential, not on length of time filter is operated. Different areas and water conditions will have different normal cleaning intervals.

NOTICE: Some pool disinfectants may clog filter media. To maximize media life and filter cycle time, closely follow disinfectant manufacturer’s instructions when cleaning pool or filter.

On a new pool installation, we recommend:

1. Turn to Page 8 for instructions and disassemble the filter after the initial cleanup.

2. Remove and hose down the element assembly to remove contaminants.

WARNING

Risk of drowning and falls. Place equipment  at least 4 feet from pool  so that children cannot climb over it into pool.

sss

Do not allow children to stand or play on filter or pump.

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

Filter mount must

Provide space and lighting for easy access for routine maintenance.

Provide adequate ventilation and drainage for pump.

Be protected from weather and reasonably level.

Be less than three feet above pool water level.

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

Piping

All piping must conform to local and state plumbing and sanitary codes.

Never use pipe joint sealing compound on pipe and fittings that are plastic or may come into contact with plastic. To seal threaded connections on PVC pipe and fittings, use only Teflon pipe joint compound may cause stress cracking of plastic components. Use pipe joint compounds only on metal-to-metal joints.

Support pipe independently to prevent strains on filter or pump.

Use 1-1/2” or 2” pipe to reduce pressure losses.

Before installing, open filter to make sure internal air bleed tube and air bleed filter (Key Nos. 13 and 14, Page 14) are in place. Clean air bleed periodically.

NOTICE: Filter locations remote from pool are possible but may require larger

pipe to produce adequate flow through filter.

Check local codes if considering a 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 tank or loss of prime at pump; pump discharge line leaks may show up as dampness or jets of water.

Valves

A check valve installed between pool and filter outlet will prevent contaminants from draining back into pool.

NOTICE: A check valve between filter and pool will also prevent possible backflow which could dislocate element from its seat.

A check valve installed between filter and heater will prevent hot water from heater from backing up into the filter and deforming filter elements.

NOTICE: Damaging filter elements through excessive heat voids the warranty.

Electrical

BE SURE filter grounding and bonding meets local and National Electrical

Code standards. All wiring, grounding and bonding of associated equipment must meet local and National Electrical Code standards.

A. Turn pump OFF before starting procedure.

B. Properly seat filter clamps and securely tighten clamp knobs before

proceeding.

C. Read decal on tank.

NOTICE: Tightly close plugs or valves in #3 Tank Drain Port and #4 Auxiliary

Drain Port.

1. Open air release valve (Key No. 2, Page 14) located on top of filter tank head.

NOTICE: Air trapped inside the filter greatly increases the explosion hazard. The air release valve allows you to get accumulated air out of the filter tank. At startup, open the air release valve and make sure that it is running a solid stream of water before putting the filter in service.

2. Start pump.

3. When a steady stream of water comes from air release valve, close valve.

4. After filter is operating, record filter pressure gauge reading in owner’s manual for future use.

NOTICE: When installed on a new pool, filter element may need cleaning after approximately 48 hours of operation.

NOTICE: A new or recently cleaned filter element may pass some foreign material until it builds up a sufficient coating to stop all “fines”. This is normal; a short operational period will correct the condition.

Check pressure gauge; if pressure has risen more than 10 PSI (70kPa) above startup pressure, remove and clean element.

FILTER CLEANING PROCEDURE

NOTICE: Keep track of filter operating pressure. When pressure reaches 10 pounds per square inch (PSI) (70kPa) above initial operating pressure, clean filter element.

OTICE:When sanitizing your pool using PHMB (polyhexamethylene

biquanide based) sanitizers, use only PHMB cleaners to clean the module. When using PHMB sanitizers, the filter module MUST be cleaned more thoroughly and frequently than for a pool using chlorine. Follow manufacturer’s instructions carefully. Use of any other type of cleaners with PHMB pool sanitizers will void the filter’s warranty.

NOTICE: If filter is used with a spa, soak element (see Step 2, “Special Cleaning Instructions”) at each regular cleaning.

With hose, wash foreign material from inside of base. Try to avoid washing debris into outlet port (see Figure 12).

NOTICE: Be sure inside surface of base is clean.

Washing Filter Element (See Figures 13 and 14):

1. Use a garden hose with straight flow nozzle to wash down filter element (Figure 13).

2. Work from the top down; wash down all pleats. Wash between all pleats.

3. Turn element while spraying to wash down entire outside of element.

4. Repeat wash down process for inside of filter element. Hold nozzle as close to inside of pleats as possible (Figure 14).

NOTICE: BE SURE all dirt and foreign materials are washed away from INSIDE pleats of element.

FIGURE 13

FIGURE 14

SPECIAL CLEANING INSTRUCTIONS:

Risk of fire or explosion. Isolate filter from system before chemi-

cal cleaning; rinse filter and elements completely before returning to service.

If filter cannot be isolated, remove media and clean at another location. Follow chemical manufacturer’s instructions for use. Do not mix chemicals except as directed by manufacturer. Do not allow cleaning chemicals to mix with or to come in contact with chlorine, bromines, other chemicals, or chemical feed devices.

NOTICE: Some pool disinfectants may clog filter media. To maximize media life and filter cycle time, closely follow disinfectant manufacturer’s instructions when cleaning pool or filter.

For stubborn deposits, proceed as follows:

1. Follow Regular Cleaning Procedure (above).

2. If deposits remain, soak element at least one hour with one of the following solutions:

A. Commercial filter cleaner (see chart: follow manufacturer’s instructions

for use), or B. One cup automatic dishwasher detergent to five gallons of water, or C. One cup Tri Sodium Phosphate (TSP) to five gallons of water.

3. Wash off with water to remove oils, dirt and remaining cleaner solution.

TROUBLESHOOTING GUIDE

A. Short Cycle:

OTICE: Time between cleanings will vary with

each installation and between different areas of the country. The following causes and remedies are for cycle times shorter than normal for your area.

NOTICE: Some pool disinfectants may clog filter media. To maximize media life and filter cycle time, closely follow disinfectant manufacturer’s instructions when cleaning pool or filter.

1. Chlorine residual too low; maintain proper residual (consult pool professional for recommendation).

2. Flow rate too high; restrict flow to rated capacity of filter (see instruction decal on filter).

3. Filter too small; install larger filter or additional filter.

4. Unstable water; consult pool professional.

5. Filter element not cleaned properly or plugged with algae, iron, calcium, etc. - see “Special Cleaning Instructions”, Page 10.

6. Heavy or improper application of powdered chlorine or chlorine pills using a binder; see “Special Cleaning Instructions”, Page 10.

7. Algae in pool - Apply heavy dose of chlorine or algaecide as recommended by pool manufacturer. Continue until algae is controlled.

B. Low flow:

1. Element is plugged; see “Special Cleaning Instructions”, Page 10.

2. Pipe blocked downstream from filter; remove obstruction.

3. Piping too small; replace with larger pipe (consult dealer for recommendation).

4. Pump hair and lint trap is plugged - empty and clean.

5. Pump impeller and diffuser worn - replace with new parts. Consult pump owner’s manual for information.

6. Pump too small for system - replace with larger pump.

2. Element cloth torn or punctured; replace element.

3. Filter too small, flow too low, or daily operating time too short, giving inadequate turnover rate; consult dealer to verify that equipment is properly sized for your pool.

4. Pump too large - overpumping - reduce flow rate.

5. Filter installed backward - replumb.

D. Long Recovery Time After Heavy Usage:

1. Residual Chlorine level is too low - add chlorine.

2. Filter too small - replace with larger unit.

3. Pump too large - reduce flow rate.

E. Filter Bypasses Dirt:

To avoid severe injury or major property damage, exactly follow instructions under “Disassembly” and “Assembly” (Pages 8 and 9)!

1. Air bleed tube and/or tube filter not in position. Exactly follow instructions in “Filter Disassembly/Assembly Procedure”, Pages 8 and 9, and reinstall correctly.

2. Element cloth torn or punctured; replace element.

3. Filter element is not seated properly in filter base; follow instructions under “Filter Disassembly/Reassembly”, Pages 8 and 9, and reposition properly.

4. Filter is plumbed backwards and element cloth is ruptured - replumb properly and replace element.

5. Colloidal fines (very small suspended dirt particles) are present and passing through element covering. Floc with alum, or if fines have already settled, vacuum to waste.

C. Pool Water Not Clear:

1. Chlorine dosage too low; maintain adequate chlorine residual (consult pool professional for recommendation).
