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 filter more frequently (that is, at a pressure increase of less than 10 PSI) in order to maintain the required flow.

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

A typical pool installation will require approximately one week to obtain and maintain the sparkle that your filter is capable of giving you.

Maximum pressure is 30 PSI (207 kPa). DO NOT connect the filter to a city water system or to an individual water well system.

The Sta-Rite cartridge filter is designed to filter water for above ground swimming pools only. On a new installation, we recommend:

1. Disassemble the filter after the initial cleanup. Follow "Filter Disassembly/Assembly Procedure" on Pages 4 and 5.

2. Remove and hose down the cartridge to remove contaminants.

Maintain pool water pH between 7.2 and 7.6. Make sure that the Posi-Ring securely locked in place before operating filter. Maintain the pressure gauge in good working order. Replace a damaged gauge immediately. Cleaning interval is based on pressure rise, not on the length of time the filter is operated. Different water conditions will have different normal cleaning intervals.

NOTICE: Some pool disinfectants may clog the filter cartridge. To maximize cartridge life and filter cycle time, closely follow the disinfectant manufacturer’s instructions when cleaning pool or filter. Failure to follow these instructions may affect warranty coverage of the cartridge.

INSTALLATION

Filter mount must:

Provide weather and freezing protection. Provide space and lighting for easy access for routine

maintenance. (See Figure 1 for space requirements.) Provide ventilation and drainage for pump. Be on a reasonably level surface and provide adequate

drainage.

Piping:

NOTICE: Make sure that the filter and all piping can be

drained for winterizing. See “Winterizing”, Page 5. NOTICE: Overtightening can crack filter ports. Use Teflon

on all threaded connections of plastic pipe and fittings.

DO NO connection to crack. Do not use sealant on unions – assemble them dry and hand tight.

Support pipe independently to prevent strains on filter. Keep piping tight and free of leaks: pump suction line

leaks may cause trapped air in filter tank or loss of prime at pump.

INITIAL START-UP

Be sure pump is OFF before starting procedure.

Do not operate filter at more than 30 PSI (207 kPa).

1. Securely lock the Posi-Ring®in place by rotating it CLOCKWISE until it “clicks” past the safety latch (see Figure 2). 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. Install the pressure gauge and the air release valve (See Figure 2) on the tank lid.

D. If the ring was already locked, remove it and the fil-

ter lid assembly. Inspect and clean the O-ring and all sealing surfaces. Relubricate the O-ring, if necessary.

OTICE:Lubricate the O-ring only with silicone grease,

s other lubricants may cause the ring to swell. DO NOT

a lubricate the Posi-Ring

or the threads on tank shell as

this may collect grit and make removal difficult. After the filter is operating, record the filter pressure

gauge reading in the owner's manual for future use.

FILTER DISASSEMBLY/ ASSEMBLY PROCEDURE

Before disassembling filter:

1. STOP PUMP.

2. OPEN air release valve and drain fitting.

3. WAIT until all pressure is released and water drained from filter tank and system before loosening

Posi-Ring

Disassembly:

1. Stop the pump.

2. Open air release valve on top of filter tank to release all pressure from inside of tank.

3. Remove the drain cap and drain all water from the tank.

4. Remove filter lid assembly as follows: a. Press the safety latch (below the ring) toward the

tank to release it (see Figure 3).

Figure 2 – Rotate Posi-Ring®until tab locks behind the safety latch.

3. Fill the trap on the pump with water.

4. Open the air release valve on top of the filter.

5. Open valves separating filter from the rest of the system.

6. Start the pump to purge air from the system.

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

SAFETY LATCH

The purpose of the safety latch is to hold the Posi-Ring

n the locked position. If the latch is damaged, replace it

s follows:

1. Press up on the small catch on the bottom of the safety latch and press or tap the latch out of the slot in the tank.

2. Slide the new latch into position until it latches in place.

NOTICE: DO NOT operate the filter if the safety latch is damaged or will not hold the Posi-Ring®in the locked position.

Assembly:

1. Inspect and clean the tank, ring threads and O-ring groove. Replace damaged parts as necessary.

2. Install the filter cartridge in the tank. Push down firmly to seal it.

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

3. Install the O-ring in the tank lid assembly O-ring groove. Be sure that the O-ring is clean and not twisted.

4. Place the Posi-Ring®squarely over the tank shell threads and rotate it CLOCKWISE until it is securely latched.

CARTRIDGE CLEANING PROCEDURE

When to Clean the Filter: The filter cartridge should normally be cleaned when the pressure gauge reading increases 10 PSI over the start-up pressure.

Follow all steps in the “Disassembly” section of this manual (Page 4).

The filter cartridge should be removed and cleaned when pressure rises more than 10 psi (69 kPa) above startup pressure.

TICE:

hexamethylene biquanide based) cleaners, use only PHMB cleaners to clean the cartridge. When using PHMB sanitizers, the filter cartridge 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 sanitizers will void the filter’s warranty.

1. Remove the drain cap and flush all foreign material from the inside of the tank before removing the filter cartridge.

2. Allow the tank to drain.

3. Lift out the cartridge and hose it down thoroughly.

When sanitizing your pool using PHMB (poly

Spray the entire cartridge surface. Allow cartridge to drain.

4. Inspect the cartridge. If necessary, repeat the washing operation. If the cartridge is damaged, replace it.

5. Follow all steps in the “Assembly” and “Initial Startup” sections of this manual (Page 4).

NOTICE: When this procedure no longer adequately cleans the cartridge, discard the cartridge and replace it with a new one.

SYSTEM INSPECTION

General:

NOTICE: DO NOT use solvents to clean the filter;

solvents may damage plastic components in the system. NOTICE: Open the air release 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 pump 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 “Cartridge Cleaning Procedure”, at left.

1. winterizing.

2. Stop the pump.

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

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

5. Gravity drain system and filter as far as possible.

6. Disassemble the filter (follow instructions under “Filter Disassembly”, Page 4). Remove the filter cartridge and store it in a warm, dry area.

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

Protect the filter from freezing. Allowing the
