Important Safety Instructions

Safety Instructions
MAXIMUM OPERATING PRESSURE OF THE FILTER IS 50 PSI.

NEVER SUBJECT THE FILTER TO ANY OPERATING PRESSURE EXCEEDING 50 PSI.

• Do not connect the system to an unregulated city water system or other external source of pressurized water producing pressures greater than 35 PSI.
• This filter operates under high pressure. When any part of the circulating system, i.e., filter, pump, valve(s), etc. is serviced, air can enter the  system and become pressurized when the system is restarted.
• Pressurized air in a system can cause product failure or also cause the filter lid to be blown off which can result in death, serious personal injury or property damage. Ensure that all air is out of the system before operating the equipment.
• To minimize risk of severe injury or death, the filter and/or pump should not be subjected to the piping pressurization test. Local codes may require the pool piping system to be subjected to a pressure test. These requirements are generally not intended to apply to the pool equipment such as filters or pumps. Jandy pool equipment is pressure tested at the factory. If however, this WARNING cannot be followed and pressure testing of the piping system must include the filter and/or pump BE SURE TO COMPLY WITH THE FOLLOWING SAFETY INSTRUCTIONS.
• Check all clamps, bolts, lids, locking devices and system accessories to ensure they are properly installed and secured before testing.
• RELEASE ALL AIR in the system before testing.
• Water pressure for test must NOT EXCEED 35 PSI.
• Water temperature for test must NOT EXCEED 100º F (38º C).
• Limit test to 24 hours. After test, visually check system to be sure it is ready for operation

NOTICE: These parameters apply only to Jandy equipment. For non-Jandy equipment, consult the equipment manufacturer.

WARNING
To avoid electrical shock hazard, which can result in serious injury or death:

• Ensure that all electrical to the system is turned off before approaching, inspecting or troubleshooting any leaking valves or plumbing that may have caused other electrical devices in the surrounding area to get wet.
• Water discharged from an improperly positioned filter or valve can create an electrical hazard which can cause death, serious injury or property damage.
• Improper dial valve installation can cause product failure or also cause the filter dial to be blown off, which can result in death, serious personal injury or property damage.
• Never attempt to adjust or remove the dial valve when the pump is running or there is pressure in the system. this can cause product failure or also cause the filter dial to be blown off, which can result in death, serious personal injury or property damage

CAUTION

• Maintain your pressure gauge in good working order. The pressure gauge is the primary indicator of how the filter is operating.
• Creating high vacuum levels can cause the tank vessel to crack and leak with the potential for property damage.
• Be sure that all provisions for waste water disposal meet local, provincial or national codes. During any backwash or draining process, 100 gallons or more of water will be discharged. Do not discharge water where it will cause flooding or damage.
• To avoid damaging the laterals (spokes), slowly add the filter media until the laterals are fully covered. Consult Installation and Operation Manual for complete sand filling instructions. Cracked or broken laterals (spokes) will cause sand to bedischarged to the pool.

CAUTION

• Use equipment only in a pool or spa installation.
• Before repositioning valve(s) and before beginning the assembly, disassembly, removal or adjustment of the lid, or any other service of the circulating system: (A) turn the pump off and shut off any automatic controls to ensure the system is not inadvertently started during servicing (B) open the air release valve. (C) wait until all pressure is relieved (air will have stopped flowing from the air release valve).
• When installing the threaded lid follow Setup section, Install the Filter Lid in this manual.
• Once service on the circulation system is complete, follow the Startup And Operation section of this manual.
• Maintain circulation system properly. Replace worn or damaged parts immediately.
• Be sure that the filter is properly mounted and positioned according to these installation instructions.

Figure 1. Filter Dimensions

Function
Jandy high rate sand filters pass unfiltered (dirty)water through sand or sand over a shallow layer of pea gravel. Water enters the filter at the inlet.Unfiltered water then passes through the diffuser(s)and moves down through the filter medium. Larger particles are deposited at the sand bed surface and finer particles are captured in the spaces between the sand grains. Filtered (clean) water then returns to the pool through the laterals.

Over time dirt and particles collected in the filter will make it more difficult for water to pass through,causing a rise in the operating pressure of the filter. When this occurs it will be necessary to perform a backwash procedure.

Remember to fill the filter halfway with water before loading the filter media.
Figure 2. Filter and Backwash Function
Filter

Backwash

During a backwash, water is routed into the outlet port from the filter pump. The water then moves up through the filter media stirring and dislodging particles and debris. The back washed water is forced back through the diffusers and out the inlet port which will be routed to waste drainage.

WARNING
Use equipment only in a pool or spa installation. Do not connect system to an unregulated city water system or other external source of pressurized water producing pressures greater than 35 PSI.

Equipment Location
All pool water recirculation system components need to be installed in accordance with the standards and instructions in effect in your county or municipality.Utmost care must be taken to ensure that the equipment is located such that it is able to be safely operated and maintained.

Equipment Pad
The filter along with the other primary components of your pool water recirculation system should be installed on a level, prepared footing, which is capable of supporting the weight of the filter and which will accommodate the use of anchoring bolts to secure the equipment in place. Check local building codes for any additional requirements. If possible the equipment pad area should be:

• Dry.
• Well ventilated.
• Supplied with sufficient drainage.
• Out of direct sunlight.
• Located away from eaves or overhangs whererain gutters are not installed.
• Away from overhanging trees or other foliage that may produce waste or debris of any kind that could clog, block or otherwise disrupt the regular operation and maintenance of the equipment.
• As close to the primary body of water as possible. Additional pipe length reduces efficiency due to pipe friction.

Filter Location
The filter must be installed on a firm, solid, nonabsorbent level surface; and per the requirements of local codes and Authority Having Jurisdiction (AHJ). Filter systems can weigh up to 1,100 lbs. Use suitably rated mounting surface materials to avoid risk of settlement, and never use sand to level the filter as the sand will wash away. Check local building codes for additional requirements. On the equipment pad, the filter should be positioned so that it is:

• At least 6 inches away from walls and/orlandscaping to allow for servicing.
• Not located below any eves, overhangs,coverings or landscaping that might prevent or impede the removal of the filter lid and/or the proper servicing or replacement of the internal components.
• At least 5 feet away from any electrical controls or inputs.
• In line, as best as possible, with other equipmentin order to minimize turns in plumbing which can result in diminished efficiency.
• Able to safely direct water drainage.
• Accessible for drainage and proper sand removal.
• Able to purge air and water safely away from other equipment, electrical controls or connections.
• Stationary and not subject to movement.

If the filter needs to be located above the water level of the pool, it can be raised 2.5 ft. without affecting the pump efficiency. A check valve is recommended on the suction line to the pump.

If the filter is to be installed below the water level of the pool, isolation valves should be installed on both the suction and return lines to prevent back flow ofpool water during any routine servicing that may berequired.

WARNING
Water discharged from an improperly positioned filter or valve can create an electrical hazard which can cause death, serious injury or property damage.

Figure 3. Filter Location Requirements

Anchoring the Filter to the Equipment Pad
In some areas, building codes require that allappliances be securely fastened to the equipmentpad in order to withstand high wind pressurescreated by hurricanes. Please follow all local codes and standards. Anchor screws and washers are not
included with the filter.

1. After placing the filter, drill a hole at each of the three (3) holes in the base of the filter. (The correct size concrete drill bit should be obtainedwhen the concrete screws are purchased.)The concrete screws must meet any and all applicable building code requirements.
2. Install the screws and washers to secure the filter to the equipment pad. See Figure 4. Do not over torque the screws.

Figure 4. Install Anchor Screws

Setup

Install Pressure Gauge
The pressure gauge is located in the accessory bag. Mount the pressure gauge/air release valveassembly, to the lid of the filter tank:

1. Place the gasket inside the bottom connection of the tee.
2. Thread the tee onto the threaded stem of the of the lid assembly.
   • It is not necessary to use PTFE tape.
3. Thread the vent plug into the larger corner hole of the tee.
4. Wrap the threads of the pressure gauge with PTFE tape and thread into the tee until watertight. Make sure the gauge is oriented properly.Do not over tighten the pressure gauge. Over tightening may cause the tee to crack.
5. Place the snap ring on the gauge after the filter is installed and the pump is running. Align the “Clean” arrow with the pressure reading and press the ring over the pressure gauge. If adjustments need to be made, hold the pressure gauge with one hand while rotating the ring with the other in order to prevent the gauge from rotating. Over rotation in either direction may cause leaks or crack the tee fitting.

Figure 5. Lid and Pressure Gauge Installation

CAUTION
Maintain your pressure gauge in good working order. The pressure gauge is the primary indicator of how the filter is operating.

Plumbing
WARNING
To avoid an electrical shock hazard, which can result in serious injuryor death, ensure that all electrical power to the system is turned off before approaching, inspecting or troubleshooting any leaking valvesor plumbing that may have caused other electrical devices in the surrounding area to get wet.

This filter operates under pressure. Install only on thedischarge side of a pump system.

When the lid is installed properly and the filter isoperated without air in the water system, this filter will operate in a safe manner.

If the system can be subjected to a higher pressure than the maximum pressure rating of any component, install an ASME® compliant automatic pressure relief valve or pressure regulator in the circulation system. Set the relief valve or pressure regulator to lowest working pressure of any of the components in the system.

DO NOT INSTALL a positive shutoff valve on the outlet plumbing of the filter. If the pump is operatedwith a closed valve at the outlet, an explosive condition could result. Sometimes equipment isolation valves are required for installations where the filter and other equipment are below the pool water level. Check valves should be used to allow for equipment maintenance without draining down the pool. If the application calls for positive ormanual shutoff valves, any shutoff valves are tobe prominently labeled “WARNING: Explosive Hazard. Do Not Run System With Valve Closed.”

In addition, the use of isolation valves could cause a no flow condition at other equipment. Running any equipment with no flow could seriously damage the equipment.

Chemical feeders and/or chlorine generators should be installed downstream of both the filter and the heater and a check valve should be installed to prevent treated water from back flowing from the chlorine generators or chemical feeders.

CAUTION
Operating at high vacuum levels can cause the tank vessel to crack and leak with the potential for property damage.

Backwash (waste) piping that discharges water at anelevation of 10 ft. or lower than the water surface of the pool should be equipped with a vacuum- breakerin the waste piping within 10 ft. in vertical drop from the elevation of the pool surface.

Plumbing Connections

1. Place the filter on the concrete pad, lined up with the inlet/outlet pipes. See Figure 3.
   • To reduce the loss of pressure, it is recommended to use a pipe equal to or greater than the diameter of the outlets, for the installation of the system.
2. Install the backwash valve.
   • Connect the inlet and outlet plumbing to the valve as detailed in the valve manual.
   • For best efficiency use the fewest possible number of fittings. This will prevent a restriction in the water flow.
   • Make all plumbing connections in accordancewith local plumbing and building codes.
   • Filter connections are provided with an o-ring seal. To avoid damage to the O-Rings, use only a silicone base lubricant on the O-Rings.
   • DO NOT USE pipe joint compound, glue or solvent on union coupling nuts.
   • Do not use Teflon® tape or pipe dope on any unions.
   • Keep piping tight and free of leaks. Pump suction line leaks may cause air to be entrapped in filter tank or loss of prime at the pump.
   • Support the inlet/outlet pipes independently to prevent any undue strains on the backwash valve.

Fill the Filter
Jandy high rate sand filters most commonly usesand as a filter medium, or sand over a shallow layerof pea gravel. See Figure 2. The use of filter mediaother than sand is also described in Setup section, Alternative Filter Media.

1. Sand density can vary depending on the sand and how much moisture it is carrying. For thisreason, consider the sand weights given inTable 1 as approximation only. The free board distance is the most important variable and should be maintained.

   • If pea gravel is used, it will cover the laterals to approximately 1″ above the laterals. See Figure 2.
   • All media to be marked as meeting NSF® requirements for sand filters.
   • Sand is to be #20 Silica Sand (.016″-.021″).
   • Pea gravel, if used, is to be 1/8″ to 1/4″ diameter range.
   • Before adding any filter media, ensure the laterals (spokes) are screwed firmly into the hub and that the hub is centered in the tank with the laterals (spokes) horizontal. Check for any broken laterals (spokes) which may have been accidentally damaged by rough handling during shipment. Replace any broken parts if necessary.

2. Fill the filter halfway with water before loading the filter media. See Figure 2.

3. Cover each of the diffusers with a plastic bag.

   • Care must be taken so that filter media does not get into the diffusers.
   • Take care not to dislodge the vent tubing and vent screen. See Figure 7.
     CAUTION
     To avoid damaging the laterals (spokes), slowly add the filter mediauntil the laterals are fully covered. Cracked or broken laterals (spokes) will cause sand to be discharged to the pool.
     WARNING
     The automatic vent screen and tubing must be positioned properly to avoid trapping air inside the filter. Trapped air can cause product failure or also cause the filter lid to be blown off, which can result in death, serious personal injury, or property damage.

4. Use a small scoop and pour pea gravel SLOWLY into the filter.

5. Level the surface of the gravel, 1″ above laterals.

6. Use a small scoop and pour in the appropriate amount of sand according to the level indicated in Table 1.

7. If using sand only, use a small scoop and pour it into the filter SLOWLY to the level indicated inTable 1.

8. Remove and coverings from the diffusers.

9. Check to ensure the vent tubing is appropriately positioned in the tank. See Figure 6.

10. Using water only, rinse away any sand or dirt particles in the threads in the top of the tank.

11. Ensure diffuser(s) are upright and centered properly.

12. Make sure that the automatic vent tubing is in place (threaded through the diffuser) and the vent screen is installed at the top of the vent tubing. See Figure 7.

Startup And Operation

Startup
This section applies to new pools and seasonal start ups.

WARNING
NEVER attempt to assemble, disassemble or adjust the filter when there is pressurized air in the system. Starting the pump while there is any pressurized air in the system can cause product failure or also cause the filter lid to be blown off, which can cause death, serious personal injury or property damage.

WARNING
NEVER start pump while standing within 5 feet of the filter. Startingthe pump while there is pressurized air in the system can causeproduct failure or also cause the filter lid to be blown off, which can cause death, serious personal injury or property damage.

1. Make sure pool is cleaned before filling with water to avoid component damage from excessive debris and dirt particles.
   • If the pool is new concrete, gunite or has a lot of debris or plaster dust which may bedifficult to remove; it is recommended that the filter be run in filtration “FILTER” mode for 48 hours before performing the backwash procedure described below.
2. Turn off the pump at the circuit breaker.
3. Check that the drain plug is in place and tight.
4. Check that the lid is correctly seated and tight.\ See Figure 5.
   • Ensure the pressure gauge/release valve assembly is fully installed in the lid.
5. Ensure the backwash piping is open.
6. Set backwash valve to the “Backwash” position.
   • If a multiport valve is used, set handle to the “Backwash” position indicated on the dial.
   • If a slide valve is used, push the handle downto the backwash position and turn the handle to lock it in place.
   • For details please review the manufacturers instruction manual for your backwash valve.
7. Restore power to the pump at the breaker.
8. If the pump does not immediately prime, the following steps can be taken to achieve prime.
   • If necessary open the pump basket lid.
   • Fill the pump basket with water to prime the system.
   • Replace the lid. (You may have to do this several times on new and seasonal start-ups.)
   • If the pump is located below the water levelof the pool, you can open the filter pressure release valve to prime the pump with water.
   • If the pump is located above the water level, remove the lid and fill the basket with water before starting the pump.
   • Prior to replacing the pump lid, check for debris around the lid O-Ring seat. Debrisaround the lid O-Ring seat will cause air to leak into the system, and make it difficult to prime the pump.
   • Hand-tighten the lid to make an air tight seal.
   • Do not use any tools to tighten the lid.
   • Ensure that the lid is secure.
   • Ensure that all isolation valves are open.
   • Ensure that the unions are tight
9. Open the air release valve by turning the thumbscrew on the back of the pressure gauge housing counterclockwise.
   • Do not remove the thumbscrew. See Figure 5.
10. Stand clear of the filter and turn the filter pump on.
11. Once the filter pump is primed and begins filling the filter. The vent hole on the pressure gauge will expel air
    • If the vent hole does not expel air, turn off the filter pump.
    • Double check that all isolation valves are open.
    • Check to ensure that the filter pump has successfully primed and is filling the filter with water.
    • Double check that the release valve thumbscrew has been loosened
12. Air venting is complete when a steady stream ofwater is being produced at the vent hole.
13. You should also see a steady flow of water being discharged from the “waste” drain line.
14. Close the air release valve by turning the thumbscrew on the back of the pressure gauge housing clockwise until the flow of water from the vent hole stops.
15. Run the filter using the backwash setting onyour backwash valve for at least 3 to 5 minutes or until water runs clear.

Operation
This filter operates with a variety of backwash valves. The operational procedures described below attempt to cover use of the most common backwash valves. However, it is always recommended that you consult the manual for the backwash valve you are using on the filter.

CAUTION
To prevent the possibility of personal injury and equipment damage, always turn the pump off before changing the position of a backwash valve.

WARNING
NEVER operate the filter system at more than 50 psi of pressure. Operating filter system in excess of 50 psi can cause product failure or also cause the filter lid to be blown off, which can cause death, serious personal injury or property damage.

WARNING
DO NOT operate filter at water temperatures above 104° F (40° C). Water temperatures above the manufacturer’s recommendations will shorten the life span of the filter and may void the warranty

Always turn off the filter pump any time you are making adjustments to the backwash valve.

1. Continue the initial backwash until the backwash water is clear (3 to 5 minutes).
   • See Step 1 in Startup and Operation section, Startup if the pool is new or contains significant hard to remove particulates such as plaster dust.
2. Turn the pump off.
3. If you are using a multiport backwash valve that has a “Rinse” position do the following:
   • Set the selector handle to the “Rinse” position.
   • Start the pump.
   • Run for 30 to 40 seconds. This helps settle the sand bed and removes fine particles.
   • Turn the pump off.
4. Set backwash valve to normal operation position.
   • If a multiport valve is used, set handle to the “Filter” position Indicated on the dial.
   • If a slide valve is used, pull the handle up to the filter position and turn the handle to lock it in place.
   • Make certain all inlet and return lines to the pool are open to allow free movement of water
   • Open the air release valve by turning thethumbscrew on the back of the pressure gauge housing counterclockwise. Do not remove the thumbscrew. See Figure 5.
5. Follow steps 10-14 from Startup and Operation section, Startup.
6. After the pressure gauge has stabilized, turn the gauge ring so that the arrow next to the word “clean” aligns with the needle of the gauge.
   • Record this initial “CLEAN” pressure. This reference will be necessary in the future.
   • As the filter cleans the water and the sand begins to clog, the pressure will increase.
   • The ring indicates an increased pressure of between 10 and 12 psi above original starting pressure.
   • When the needle of the pressure gauge aligns with the arrow next to the word “dirty”, it is time to clean the filter.
   • Ensure pump speed remains the same when recording “CLEAN” and “DIRTY” pressure.

Filter Cleaning
After 48 hours of operation on a new pool, the filter should be backwashed to clear out plaster dust and debris from the pool construction. It is not recommended to backwash the filter on a timed basis, e.g. once a month. Pool, weather, dust conditions and pool occupancy all affect the frequency of the need to backwash.

Backwashing a filter too often will actually diminish the filter performance by limiting its ability to catch finer particles. Do not run your system 24 hours a day, day after day. Allowing the filter to stop periodically will allow slight disturbance of the “muddeck” at the surface of the sand bed. This will lower the running pressure slightly after rest.

Backwashing your filter is required when thepressure gauge reading shows an increase of 10 to12 psi above the “CLEAN” filter pressure. Anotherindicator of the need to backwash is when the flowback to the pool is reduced by 30% compared to the clean filter flow amount.

1. Turn the pump off.
2. Ensure suction piping and backwash piping isopen to ensure unobstructed flow through the filter and backwash line
3. Set the backwash valve to the “Backwash” position.
   • If a multiport valve is used, set handle to the\ “Backwash” position indicated on the dial.
   • If a slide valve is used, push the handle down to the backwash position and turn the handle to lock it in place.
4. Stand clear of the filter and start the pump.
5. Backwash the filter for 3 to 5 minutes or until water runs clear.
6. Turn the pump off.
7. If the multiport valve has a “Rinse” position do the following:
   • Set the selector handle in “Rinse” position.
   • Run for one minute. This helps settle the sand bed.
   • Stop the pump.
8. Set backwash valve to normal operation position.
   • If a multiport valve is used, set handle to the “Filter” position Indicated on the dial.
   • If a slide valve is used, pull the handle up to the filter position and turn the handle to lock it in place.
   • Make certain all inlet and return lines to the pool are open to allow free movement of water.
   • Open the air release valve by turning the thumbscrew on the back of the pressure gauge housing counterclockwise. Do not remove the thumbscrew. See Figure 5.
9. Follow steps 10-14 from Startup and Operation section, Startup.
10. Align the gauge ring according to Step 6 from Startup and Operation section, Operation.
11. If the pressure gauge after the backwash procedure indicates more than 5 psi difference above that reading, it will be necessary to chemically clean the sand bed. See next section

Chemical Cleaning Procedure
Sand filter chemical cleaners remove oils, deposits and rust from the sand bed with a 12 hour overnight soaking when used according to the following instruction. Follow these instructions carefully. Do not allow the cleaning solution to be pumped back into the pool.

1. Use an approved cleaner for sand filters.
   • Approved cleaners should be available through your pool chemical retail store, or pool maintenance service or supplier.
2. If necessary, mix the proper solution per the manufacturer’s label instructions.
3. Perform the backwash procedure as described in Filter Cleaning section.
4. Shut the pump off.
5. If the filter is installed below the pool water level, close the appropriate isolation valve(s) to prevent the pool from draining.
6. Drain the water from the filter. (See next section.)
7. After filter has drained, replace cap on drain fitting.
8. Place the backwash valve in “Backwash” position.
   • Make certain backwash lines are open.
9. Introduce cleaner to the water system.
   • Follow all appropriate use and safety instructions from the filter cleaner manufacturer.
10. Follow steps 9-13 from Startup and Operation section, Startup. to fill the filter tank.
11. Turn off the pump.
12. Leave the filter valve in the “Backwash” position.
    • Use caution not to introduce cleaning solution in the main body of pool water.
13. Disconnect the power at the breaker.
14. Allow the filter to stand for 12 hours.
15. After 12 hour soak, turn on the power breaker and follow instructions in Filter Cleaning section

After chemical cleaning, your filter should return very close to the original “Clean” pressure reading on the filter pressure gauge that was noted at the time of the original installation with fresh sand. If not, note this new “Clean” pressure reading for future reference. Turn the ring on the filter gauge assembly so that the arrow next to the word “Clean” is aligned with the needle.

Draining the Filter and Removing the Filter Sand
For maintenance or repair it may be necessary todrain water from the filter or completely remove all the sand from the filter. The filter drain will allow for both water removal and the flushing of sand.

Any additional piping installed at the water drain must be removable in order to facilitate the further removal of drain components. Allow sufficient spacefor the flushing of sand from the filter. See Figure 11

CAUTION
Be sure that all provisions for wastewater disposal meet local, state or national codes. During any backwashing or draining process, 100 gallons or more of pool water will be discharged. Do not discharge water where it will cause flooding or damage.

Figure 11. Drain Valve

Drain The Filter

1. Shut the pump off.
2. If the filter is installed below the pool water level, close the appropriate isolation valve(s) to prevent the pool from draining.
3. Loosen and remove the drain cap.
   • Use caution not to misplace the drain plug.
4. Allow the filter to drain out as much water as needed.
5. Replace the plug and cap.

Remove the Filter Sand

1. Follow the draining procedure described in the Drain the Filter section.
2. Remove the filter lid.
   • Before attempting to loosen or remove the lid, turn OFF the pump and OPEN the air release valve on top of the filter.
   • DO NOT attempt to loosen or remove the lid while the pump is running or if the filter pressure gauge indicates there is pressure in the filter.
   • First, try to remove the lid by hand using the handles.
   • If removal by hand is not successful, use a mallet or soft-faced hammer to alternately strike the handles to loosen the lid.
   • Use caution not to damage the lid O-Ring or the pressure gauge assembly.
3. Using a scoop reach into the filter and remove as much sand as possible.
   • Use caution not to get sand into the diffusers.
   • The diffusers can be covered with a plastic bag to help avoid sand intrusion.
4. If available use a wet/dry vacuum to remove as much of the remaining sand as possible.
5. Loosen and remove the universal coupling nut.
6. Carefully draw out the drain screen.
7. Use caution not to misplace the O-Ring.
8. Use water to flush remaining filter media fromthe filter tank.
   • The larger tank drain is a universal union fitting. Sand removal is easiest without further restriction at this fitting. However, if a short piece of piping is desired to direct the sand being flushed away from the filter base, auniversal tailpiece and union nut can be used. See Figure 11.

Maintenance

General Maintenance

• The outside of the filter can be cleaned with a mild detergent and water. Rinse with water.
• Do not use strong cleansers or solvents toclean the filter, solvents will damage the plastic components of the filter.
• Check pressure during operation at least once a week.
• Check for and remove any debris from the skimmer basket and strainer basket on pump regularly.
• Check pump and filter for any leaks. If any leaks develop, turn off the pump and call a qualified pool service technician.
• Product safety signs or labels should beperiodically inspected and cleaned by the product user as necessary to maintain good legibility from a safe viewing distance.
• Product safety signs or labels should be replaced by the product user when a person with normal vision, including corrected vision, is no longer able to read the safety signs or label message panel text at a safe viewing distance from the hazard.
• In cases where the product has an extensiveexpected life or is exposed to extremeconditions, the product user should contact either the product manufacturer or some other source to determine means for obtaining replacement signs or labels.
• Installation of new replacement safety signs or labels should be in accordance with the sign or label manufacturer’s recommended procedure

Pressure Gauge

• During operation of the filtration system, check the pressure gauge/air release assembly for air or water leaks at least oncea week.
• Keep the pressure gauge in good working order. If you suspect a problem with the gauge, Jandy® recommends you call aqualified service technician to do any work onthe filter/pump system

Winterizing

1. Backwash the filter. See Filter Cleaning section.
2. Turn OFF the pump at the circuit breakers.
3. Open the air release valve on top of the filter.
4. Remove the drain cap at the base of the filterto ensure that the tank is empty. Store the draincap and seal in a safe place. Do not reinstall until next season at start-up.
5. Drain system piping of all water.
   • If using a multiport backwash valve that hasa “Winterize” position, move selector lever tothat position. The “Winterize” position which leaves all ports partially open, and on somebackwash valves also moves the seal to a relaxed position.
6. Cover the system with a tarpaulin or plastic sheet to protect it from the weather. Do not wrap electrical motors in plastic
