GENERAL INFORMATION

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.

n some pools, accessories such as fountains or pool

I 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.

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 50 PSI (345 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 swimming pools and hot tubs only. On a new installation, we recommend:

1. Disassemble the filter after the initial cleanup. Follow "Filter Disassembly/Assembly Procedure" on Page 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.

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

drainage.

Electrical:

BE SURE pump grounding meets local and National

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

INITIAL START-UP

Be sure pump is OFF before starting procedure.

Do not operate filter at more than 50 PSI (345 kPa).

1. Securely lock the Posi-Ring®in place by rotating it

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. Install the pressure gauge and the air release valve

(See Figure 3) on the tank lid.

FIGURE 2 – Assemble Air Bleed Tube as shown.

Piping:

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

drained for winterizing. See “W NOTICE: Overtightening can crack filter ports. Use Teflon®tape, Plasto-Joint Stik®, or Silastic 732®RTV

on all threaded connections of plastic pipe and fittings.

DO NOT use pipe compounds on filter; it will cause the 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.

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 4).

SAFETY LATCH

The purpose of the safety latch is to hold the Posi-Ring in the locked position. If the latch is damaged, replace it as 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 sealing area inside the

upper tank lip with silicone base grease, as other lubricants may cause the ring to swell. DO NOT lubricate the Posi-Ring®or the 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. NOTICE: Do not remove the O-ring unless you need to replace it.

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

5. Follow instructions in the “Initial Startup” section of this manual.

Posi-Ring

5. Inspect the O-ring for cuts, cracking, deformation or signs of wear; replace if necessary

NOTICE: Do not remove the O-ring unless you need to replace it. To remove it, hook it out of its groove with a stiff curved piece of wire inserted through the small access slot in the bottom of the tank lid assembly

Hold the latch in the release position and rotate the ring COUNTERCLOCKWISE to remove it. If the ring is difficult to turn, tap it gently with a rubber mallet to overcome initial resistance.

CARTRIDGE CLEANING PROCEDURE

When to Clean the Filter: The filter cartridge should normally be removed and cleaned when the pressure

auge reading increases 10 PSI over the start-up

ressure.

p Follow all steps in the “Disassembly” section of this

manual (Page 5). NOTICE: When sanitizing your pool using PHMB (poly-

hexamethylene biquanide based) cleaners, use 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 pool 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. 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” (Page 5) and “Initial Startup” (Page 4) sections of this manual.

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.

WINTERIZING

NOTICE: Protect the filter from freezing. Allowing the filter to freeze will damage it and will void the warranty. If possible, take the system indoors for storage.

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

2. Stop the pump.

3. Open the air release valve; open any system valves. 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 5). and store it in a warm, dry area.

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

Remove the filter cartridge
