WARNING

Hazardous Pressure!

Can cause tank explosion.

Do not connect filter to compressed air under any circumstances.

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.

• With a modular Diatomaceous Earth (DE) filter in place and operating correctly, clean water is returned to the pool faster than 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.

• Do not use more than the recommended amount of DE in your filter. Excess DE can cause a buildup of DE and “bridging” between the pleats which will plug the filter.

• Maximum pressure is 50 PSI (345 kPa). DO NOT connect the filter to a city water system or to an individual water well system.

Hazardous pressure. Open air release valve to vent all air from system before operating system. NEVER operate filter with air trapped inside.

• The Sta-Rite modular DE filter is designed to filter water for swimming pools. On a new pool installation, we recommend:

1.Disassemble the filter after the initial cleanup.

Hazardous pressure. To prevent severe injury or major property damage, exactly follow "Filter Disassembly/Assembly Procedure" on Pages 6 and 7.

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

• Maintain pool water pH between 7.2 and 7.6.

• Make sure that internal air bleed tube and filter are clean and installed properly at top of module before operating filter.

• Make sure that Posi-Lok™ Ring is securely locked in place before operating filter.

• Maintain pressure gauge in good working order. Replace a damaged gauge immediately.

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

• Check local codes for restrictions on waste water and DE disposal requirements.

NOTICE: Some pool disinfectants may clog filter module. To maximize module life and filter cycle time, closely follow disinfectant manufacturer’s instructions when cleaning pool or filter (see Page 8).

Pressure Gauge Reading at Startup _____________________________

When to Clean the Filter

The filter module should normally be cleaned when the pressure gauge reading increases 10 PSI over the start-up pressure (record the start-up pressure under “Owner’s Information”, below, right).

In some pools, accessories such as fountains or pool cleaners may be noticeably affected by the normal decrease in flow as the filter becomes dirty. If so, clean the filter more frequently (that is, at a pressure increase of less than 10 PSI) in order to maintain the required flow.

INSTALLATION

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

Assembly

• Unpack the pump or pump and base and check for transit damage.

• Open the accessory package.

• Install hoses with adapters and clamps provided in the accessory package. Run one line from the skimmer to the pump suction port and the other line from the filter outlet to the pool inlet fitting.

Filter mount must:

• Be solid, level, rigid, vibration free, and provide for adequate drainage.

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

• Be protected from excess moisture.

• Provide weather and freezing protection.

• Provide adequate ventilation to prevent motor from overheating.

• Provide space and lighting for easy access for servicing pump and piping (See Figure 1, Page 4, for space requirements).

• Be installed with the trap suction inlet below the pool water level at all times (to allow pump to prime).

Piping (See Figure 1B for correct connections):

• Piping must conform to local/state plumbing and sanitary codes.

• Use teflon tape, Plasto-Joint Stik®1, or Silastic 732®on all male connections of plastic pipe and fittings. DO NOT use pipe compounds on plastic pipe; it will cause the pipe to crack. Do not use sealant on unions – assemble them dry and hand tight.

• Support pipe independently to prevent strains on filter.

• Fittings restrict flow; for best efficiency use fewest possible fittings.

• For ease of maintenance, use Sta-Rite union couplings to connect the piping to the filter inlet and outlet ports.

• 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.

• NOTICE: Overtightening can crack filter ports.

Valves:

• Install valves on both sides of the filter to isolate filter for easy servicing. NOTICE: Install heater downstream of filter. If heater does not incorporate

a check valve, install one at the heater inlet to prevent hot water from backing up into the filter. Filter modules damaged by excessive heat will void the warranty.

• A check valve installed ahead of filter inlet will prevent contaminants from draining back into pool.

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.

NOTICE

Make sure that the filter and all piping can be drained for winterizing. See “Winterizing”, Page 9.

Hazardous pressure. Can cause severe injury or major property damage from tank blow up.

Release all pressure and read instructions before working on filter.

INITIAL START-UP

Be sure pump is OFF before starting procedure.

Do not operate these filters at more than 50 PSI (345 kPa) under

any circumstances! To prevent serious damage to the element fabric, NEVER run

your DE filter without a diatomaceous earth precoat!

1. Securely lock Posi-Lok™ ring in place by rotating ring CLOCKWISE until it

“clicks” past the safety latch (see Figure 3). Stop turning as soon as the ring clicks past the latch. The ring may feel slightly loose, but it will tighten up when pump is on and filter is under pressure.

2. Fill trap on pump with water.

3. Open air release valve on top of filter.

4. Open isolation valves.

5. Start pump to purge air from system.

6. When steady stream of water comes from air release valve, close the

valve. NOTICE: Leaking around the Posi-Lok™ ring may indicate that the ring is not fully locked. In this case, proceed as follows:

A. Stop the pump, close the isolation valves, and open the air release

valve to release any pressure within the filter.

B. Remove the drain plug and drain all water from the filter. C. Push down on the top of the filter to fully seat the upper tank shell.

D. Rotate the Posi-Lok™ clockwise until it locks behind the safety latch

(see Figure 3).

E. If the ring was already locked, remove it and the upper tank shell.

Inspect and clean the O-ring and all sealing surfaces. Relubricate the

O-ring. NOTICE: Lubricate O-ring only with the silicone grease provided or equivalent, as other lubricants may cause the ring to swell. DO NOT lubricate Posi-Lok™ ring or threads on lower tank shell as this may collect grit and make removal difficult.

7. To prepare precoat slurry, mix diatomaceous earth (DE) and water. Use

four pounds of DE for Model PLD70; use six pounds of DE for Model PLD50. DO NOT use more DE than recommended. NOTICE: Using more than the recommended amount of DE will clog the filter. Using less than the recommended amount will give an uneven precoat and shorten the life of the element.

8. Empty slurry slowly into skimmer to precoat filter element with an even fil-

tering precoat. After filter is operating, record filter pressure gauge reading in owner's manual for future use. NOTICE: When installed on a new pool, after approximately 48 hours of operation disassemble filter and clean out plaster dust , construction debris, etc. (see “Module Cleaning Procedure", Page 8).

FILTER DISASSEMBLY/ ASSEMBLY PROCEDURE

Hazardous pressure. Before disassembling filter:

1. STOP PUMP.

2. CLOSE isolation valves.

3. OPEN air release valve and drain fitting.

MODULE CLEANING PROCEDURE

Risk of chemical burns. Do not attempt to acid clean the filter or module. If the filter requires acid cleaning, have a trained pool professional do the job. Follow all steps in the “Disassembly” section of this manual.

The filter module should be removed and cleaned when pressure rises more than 10 psi (69 kPa) above startup pressure. See also “When to Clean the Filter,” at left.

NOTICE: Do not expose the filter module to sunlight for any extended period of time.

NOTICE: When sanitizing your pool using PHMB (polyhexamethylene biquanide based) cleaners, 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 cleansers with PHMB pool sanitizers will void the filter’s warranty.

NOTICE: Avoid washing filter debris into the outlet port. Remove drain plug and flush foreign material from inside of tank before removing filter module.

1. With a hose equipped with a soft flow nozzle, wash as much dirt as possi-

ble off of the filter module while it is still inside the tank. Allow tank to drain completely.

2. Make sure that the inside of the tank is clean. Lift out the module and

hose it down thoroughly. Spray the entire module surface. Allow module to drain.

3. Inspect the module. If necessary, repeat the washing operation. If the

module is damaged, replace it. NOTICE: If this cleaning method does not remove all deposits, see

“Special Cleaning Instructions” section in this manual.

4. Inspect and clean air bleed filter at top of module.

5. Follow all steps in the “Assembly” and “Initial Startup” sections of this man-

ual.

Special Cleaning Instructions:

Use this procedure to clean scale or oils which are not removed by hosing down module. Be sure to dispose of spent chemicals according to all applicable codes and waste disposal ordinances. Use a soft stream nozzle to minimize flying water and spray.

Risk of fire or explosion. Isolate filter from system before chemical 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.

1. Sponge or spray the module according to chemical manufacturer’s direc-

tions.

2. If soaking is required, remove the module from the filter tank and sub-

merge it in a separate tank. Follow cleaner manufacturer’s instructions carefully.

3. After completing chemical manufacturer’s instructions, drain and rinse the

module completely. Dispose of cleaners in accordance with local codes and disposal ordinances.

4. Rinse the inside of the filter tank. Drain it completely.

5. Follow instructions in the “Assembly” and “Initial Startup” sections of this

manual.

When to Clean the Filter

The filter module should normally be cleaned when the pressure gauge reading increases 10 PSI over the start-up pressure (record the start-up pressure under “Owner’s Information”, Page 3).

SYSTEM INSPECTION

General:

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

NOTICE: DO NOT use solvents to clean the filter; solvents may damage plastic components in the system.

NOTICE: Open the air bleed valve and bleed all air from the filter each time the pump is stopped and restarted.

Weekly Inspection:

1. Remove debris from the pool skimmer basket.

Stop the pump; open the air release valve to release all pressure.

3. Remove the trap cover and basket; remove debris.

4. Check the pump for leaks. If found, see the pump owner's manual.

5. Replace the trap basket and the cover. Tighten the cover securely hand tight. DO NOT use a lid wrench to tighten it.

6. Start the pump. When the filter air release valve runs a solid stream of water, close the valve.

7. When the system has returned to normal operation, check the filter pressure. If the filter pressure is 10 PSI (69kPa) or more higher than the initial startup pressure, the filter needs cleaning. See “Module Cleaning Procedure”, Page 8.

WINTERIZING

Explosion hazard. Purging the system with compressed air can cause components to explode, with risk of severe injury or death to anyone nearby. Use only a low pressure (below 5 PSI), high volume blower when air purging the pump, filter, or piping.

NOTICE: Protect the filter from freezing. Allowing the filter to freeze will damage it and will void the warranty.

1. Clean the filter according to instructions (Page 8) before winterizing.

2. Stop the pump.

3. Open the air release valve; open all the system valves.

4. Remove the drain plugs from the trap, pump, and filter.

5. Drain the system piping.

A. Gravity drain system as far as possible. B. Protect areas which retain water with non-toxic propylene glycol

antifreeze (“RV antifreeze”).

6. Loosen the union nuts (if used) to drain all water from the filter interior.

Leave these nuts loose until the system is restarted.

7. Disassemble the filter (follow instructions under “Filter Disassembly”,

Pages 6 and 7). Remove the filter module and store it in a warm, dry area.

8. If the filter is equipped with an optional internal spring check valve (in the

tank outlet), manually open the check valve to allow any water trapped in the tank to drain.

9. Cover the filter with plastic or tarpaulin to prevent water entrance and

freezing.

NOTICE

The filter outlet piping will not empty through the filter drain. Make sure that the outlet piping has a separate drain for winterizing.

1. Short Cycle Time:

NOTICE: Cycle Time 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.

A. Chlorine residual too low; maintain proper resid-

ual (consult pool professional for recommendation).

B. Flow rate too high; restrict flow to rated capacity

of filter (see instruction plate on filter or specifica-

tions on Page 4). C. Filter is too small; install an additional filter. D. Improper/insufficient precoat; see precoat in-

structions (Page 6). E. Filter module is dirty or plugged; thoroughly

clean the filter (see No. 4, “Plugged Module

Cloth”, and “Module Cleaning Procedure", Page

8). F. Too much DE; check for clogged filter module. G. Water is chemically out of balance; consult pool

professional.

H. Algae in the pool. Apply heavy dose of chlorine

or algicide as recommended by the pool manufacturer.

2. Low Flow/High Pressure:

A. Elements plugged; clean filter thoroughly (see

Page 8).

B. Pipe blocked downstream from filter; remove ob-

struction.

C. Piping too small; use larger pipe (consult dealer

for sizing).

D. Filter area too small; install an auxiliary filter

(consult dealer for recommendation).

E. Outlet port check valve obstructed (if applicable);

remove obstruction to allow valve to open.

3. Low Flow/Low Pressure:

A. Pump too small; consult dealer for recommenda-

tions.

B. Plugged pump or plugged hair and lint trap;

clean thoroughly.

4. Plugged Module Cloth:

NOTICE: The pleated filter material may look matted after use. However, as long as the DE adheres to the pleated cloth, the filter is operating properly.

A. Insufficient precoat; see precoat instructions

(Page 6).

B. Insufficient cleaning; follow cleaning instructions

closely and clean thoroughly (see Page 8).

C. Water is chemically out of balance; consult pool

professional.

D. Excessive air in filter; non-precoated areas may

plug. Vent air from tank and check for pump suction pipe leaks. Clean air bleed filter in grid as-

sembly with a hose and soft flow nozzle. E. Filter is too small. Install an additional filter. F. Pool water contains iron. See “Special Cleaning

Instructions”, Page 8. G. Algae in pool. Apply heavy dose of chlorine or

algicide as recommended by the pool manufac-

turer. H. Use of incorrect chemicals with PHMB sanitizers.

Replace filter module. I. Not enough D.E. precoat. Filter requires 6 lbs.

(2.7 kg.) of D.E. for adequate precoat.

5. Pool Water Not Clean:

A. Chlorine residual too low; maintain adequate

chlorine residual (consult pool service technician

for recommendation). B. Broken filter module passing DE into pool; re-

place defective module. C. Insufficient or improper precoat; follow precoating

instructions and use recommended amount of

DE (see Page 6). D. Inadequate turnover rate; consult dealer to verify

that equipment is properly sized for your pool. E. Pump is too large and is overpumping. Reduce

the flow rate. F. The filter is installed backwards. Reinstall it cor-

rectly. G. Pool water contains iron. See “Special Cleaning

Instructions”, Page 8. H. Heavy or improper application of powdered chlo-

rine tablets using a binder. See “Special Cleaning

Instructions”, Page 8. I. Algae in the pool. Apply heavy dose of chlorine

or algicide as recommended by the pool manu-

facturer.

6. Pool Accessories Stop Working:

A. Clean filter and observe performance of acces-

sories. B. If accessories perform better after filter has been

cleaned, use a shorter cleaning cycle for the filter

(that is, clean the filter after a pressure rise of

less than 10 PSI).
