Read through the instructions completely before starting the procedure. Before starting the procedure, use the parts list at the back of these instructions to identify the parts that are in your kit. In addition to the parts supplied in this kit, a small amount of silicone sealant is required. If any parts are missing from the kit please call your local Jandy distributor for assistance. For technical assistance, please contact the Zodiac Pool Systems, Inc. Technical Support Department at 1.800.822.7933. A. Remove the Lid WARNING SHOCK HAZARD! H0332500- Turn off all switches and the main breaker in the pool/spa heater electrical circuit before starting the replacement procedure. Failure to comply may cause a shock hazard resulting in severe personal injury or death. WARNING Never attempt to adjust or remove the lid when the pump is running or there is pressure in the system. This 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. 1. 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. 2. First, try to remove the lid by hand using the handles. 3. If removal by hand is not successful, use a mallet or soft-faced hammer to alternately strike the handles to loosen the lid. B. Drain Water From The Filter 1. Remove the water drain cap and drain the water from the filter. See Figure 1. C. Remove the Sand From the Filter 1. The sand may be removed by scooping it out through the filter lid opening, vacuuming it out with a suitable wet/dry shop vacuum supplied by a GFCI protected circuit, or may be flushed out of the filter through the large fitting at the drain. See Figure 2.

Sand Flushing Fitting 2. If desired, a universal tailpiece connection, part number R0449000 (not included in kit), can be used with a short piping section to direct the flushed sand away from the base of the filter. See Figure 3. 3. Rinse the internal piping to remove the sand. D. Disconnect the Internal Piping Assemblies Inside the Filter CAUTION This procedure must be followed exactly. Failure to follow the procedure exactly can result in system leaks or property damage. 1. Cut the cable tie that secures the piping. See Figure 4. 2. Remove the hex head screws that connects the hub pipe subassembly to the outlet pipe subassembly. 3. Disconnect the hub pipe subassembly from the outlet pipe subassembly. Inlet Pipe Subassembly Figure 4. Piping Components 4. Remove the hex head screw that connects the wye subassembly to the inlet pipe subassembly. Disconnect the wye subassembly. 5. Unscrew the inlet pipe subassembly from the tank inlet fitting. 6. Use a brush to clear all sand from the exposed fitting threads and rinse with water. Removal of the nuts will be difficult if there is sand in the fitting threads. Note: Make sure that the exposed threads are free of sand before continuing with the next step. 7. Remove the nuts from the bulkhead fittings. Page 3 Note: Do not rotate the bulkhead fittings. Use the flats on the bulkhead fitting to hold it from rotating while the nut on the inside of the tank is removed. 8. Thoroughly clean any parts that will be reused. 9. Reassemble fittings taking care that the curved surfaces of the spacers are towards the tank. Ensure that the wide spacer on the outside of the tank is on the top (outlet) port, and the narrow spacer is placed on the bottom (inlet) port. See Figure 5. 10. When tightening the nuts on the bulkhead fitting assemblies, DO NOT rotate the bulkhead fittings. Orient the bulkhead fittings such that the wrench flat with the part number on it faces up. This will put the keyway in the bulkhead fitting at the top and will keep the curvature of the spacers properly matched to the curvature of the tank. See Figure 5. Use the wrench flats on the bulkhead fitting to hold it in this position and do not rotate the bulkhead fitting while the nuts are being tightened inside the tank. E. Reassemble the Internal Piping Assemblies Inside the Filter Note: All parts must be rinsed and flushed clean of sand before assembly, inside and out. If old laterals are being reused, brush any filter media from the slots. 1. Make sure the keyways in the inlet and outlet fittings are dry. Place a dab of silicone sealant (about ¼ inch diameter) in each of the keyways against the nut of both the inlet fitting and outlet fitting (silicone sealant is not provided in the kit). 2. Thread the inlet pipe assembly (this is the assembly with the shorter piece of pipe with four (4) holes Inner Spacer (Curved Side Towards the Tank) Nut Wide Spacer on Outlet Fitting (Curved Side Towards Tank) Flat Gasket Bulkhead Fitting O-Ring Narrow Spacer on Inlet Fitting (Curved Side Towards Tank) Figure 5. Inlet and Outlet Fitting Parts Slip Ring drilled and a female adapter on the opposite end) onto the inlet bulkhead fitting hand tight only. Adjust the pipe so a screw hole is facing up. Refer to Figure 4. 3. While holding the pipe of the hub sub assembly, place the hub inside the top of the tank and thread the laterals into the hub. Ensure laterals are threaded fully into the hub and are hand tight. Lower the hub and laterals assembly to rest on the tank bottom, and turn the elbow away from the bulkhead fittings to provide working room for the next steps. 4. Thread the outlet pipe assembly (this is the assembly with the longer piece of pipe with four (4) holes drilled and a female adapter on the opposite end) onto the inlet bulkhead fitting hand tight only. Adjust the pipe so a screw hole is facing up. 5. Prepare the wye subassembly. The diffuser pipe subassemblies may be connected to the wye subassembly before it is placed into the filter, or afterwards. Use a hex head screw to attach the diffuser pipe subassemblies to the wye. Insert the assembly into the filter. Connect the wye to the inlet pipe assembly, align the screw holes and fasten in place using a hex head screw. 6. Connect the elbow of the hub pipe assembly to the outlet pipe assembly, align the screw holes and fasten in place using a hex head screw. 7. Thread the cable tie through the hole in the wye plate, wrap it around the hub pipe and fasten it tight around the pipe. 8. Install the air relief tubing and vent screen as follows: a. The body of the compression fitting connector should be fastened firmly into the threaded hole in the outlet pipe assembly. Loosen the threaded cap on the connector about one (1) turn from the tight position, but do not remove this cap from the fitting. b. Slide the tubing into the end of the cap until it bottoms out. Tighten the end cap and check the tubing. It should not pull out. 9. Screw the diffusers hand-tight onto the diffuser pipes. 10. Complete the assembly of the air relief. Thread the free end of the air relief tubing through the diffuser (see Figure 6). Slide the vent screen with its grommet onto the end of the tubing so that the tubing is approximately 3/4 the distance into the screen. Page 4 F. Refilling the Filter with Sand Lid/Top of Filter Jandy high rate sand filters most commonly use sand as a filter medium, or sand over a shallow layer of pea gravel. If pea gravel is used, it will cover the laterals to approximately 1 above the laterals. The use of filter media other than sand is also described in Section G. 1. Sand density can vary depending on the sand and how much moisture it is carrying. For this reason, consider the sand weights given as approximation only. Determine the actual amount of sand to add based on freeboard dimension shown in Table 1. Vent Screen in Close Proximity to Filter Lid Diffuser Venting Tubing to Fitting in Piping Table 1. Required Sand Level Model Freeboard F inches (cm) JS100-SM 11 1/4 (31) Notes: 2. Sand Only lbs (kg) 600 (273) Layered Media* Pea Gravel lbs (kg) Sand lbs (kg) Figure 6. Automatic Vent Positioning Freeboard F 175 (80) 425 (193) 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. Sand or Sand and Gravel CAUTION To avoid damaging the laterals (spokes), slowly add the filter media until the laterals are fully covered. Cracked or broken laterals (spokes) will cause sand to be discharged to the pool. 3. Add water to approximately 4 inches above the level of the laterals. 4. Place a plastic bag over each of the diffusers to completely cover all of the holes. Keep the diffusers covered until the addition of the filter media is completed. 5. If used, pour pea gravel SLOWLY into the filter first. Level the surface of the gravel, and then pour in the appropriate amount of sand to the level indicated in Table 1. If using sand only, pour it into the filter SLOWLY to the level indicated in Table 1. Be careful not to dislodge the vent tubing from its fitting in the piping while adding filter media. Refer to Figures 6 and 7. 6. Remove the plastic bags from the diffusers. Wash away any sand or dirt particles in the threads in the top of the tank. 7. Ensure diffuser(s) are upright and centered properly. Figure 7. Automatic Vent Positioning 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. 8. 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 6. G. Use of Zeobrite® as an Alternative to Sand As an alternative filter media for use instead of sand, Zeobrite has been qualified for use in Jandy JS series filters. 1. For filter sizes of 30 inches in diameter and greater, it is recommended that a pea gravel bed be used before adding the filter media. See Table 2 for the type and amount of pea gravel to use. Page 5 Ensure the top surface of the pea gravel is flat before adding filter media. Air Release Valve Vent Hole Using the correct pea gravel will ensure that the filter media is evenly lifted during backwashing cycles and settles evenly after backwashing to optimize filter performance. The pea gravel will cover the laterals to approximately 1 above the laterals. 2. Fill the filter with Zeobrite® to the level shown in Table 2. The weight of the material shown is approximate. See Figure 7 for the illustration of Freeboard . Table 2. Required Zeobrite Level Model JS100-SM Freeboard F inches (cm) 11 1/4 (31) Air Vent Screen Lid Flange Fully Seated Against Tank Figure 8. Filter Lid Installation light coating of liquid dish washing detergent or bar hand soap with some water to the lid sealing surface on the top of the tank before installing the lid. Do not use any type of oil or grease that can cause sand to get caught in the threads. Thread the lid into the tank, making certain that the lid threads in smoothly. If resistance is felt while turning, remove the lid and ensure that it is not being crossthreaded into the tank and the threads are free of sand. Use the handles to tighten the lid handtight only. Do not use impact or hammers when installing the lid. Layered Media Pea Gravel* lbs (kg) Zeobrite lbs (kg) 175 (80) 270 (122) * Pea Gravel is to be 1/8 to 1/4 in diameter. H. Lid Installation WARNING Follow these instructions carefully. Improper lid installation can cause product failure or also cause the filter lid to be blown off, which can result in death, serious injury, or property damage. WARNING Never attempt to adjust or remove the lid when the pump is running or there is pressure in the system. This 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. 1. Ensure that the lid seal is fully seated within the groove in the flange of the lid. 2. Before installing the lid, ensure that the air vent screen at the top of the air vent tubing is properly located above the diffuser such that it will be close to the underside of the lid when the lid is installed. See Figure 8. WARNING Inspect the lid and tank for any damage before installing the lid. A damaged lid or tank could cause the lid to be blown off which can result in death, serious personal injury, or property damage. 3. Inspect the threads to make certain that they are free of sand particles and wipe the threads on the tank and lid clean of any sand or debris. Apply a WARNING Fiberglass and threads have sharp edges. To avoid cuts, use a brush to clean threads free of sand or dirt. 4. When the lid is fully installed, the seal flange must contact the surface of the tank. 5. If not already in place, the filter gauge/air relief valve assembly should be installed. I. Start-Up and Operation WARNING NEVER start pump while standing within 5 feet of the filter. Starting the pump while there is 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 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. Page 6 push the handle down to the normal filter position and turn the handle to lock in place. CAUTION 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 void the warranty. Once service on the circulating system is completed, the system must be properly vented of all air. Do the following steps: 1. Turn off the pump. Switch off the circuit breaker to the pump motor. 2. Check that the drain plug is in place and tight. 3. Check that the tank lid is correctly seated and tight, see Figure 8, and ensure the pressure gauge/ relief valve assembly is fully installed in the lid. 4. Ensure the backwash piping is open. 5. Open the pump hair/lint pot lid and 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.) 6. Completely open the air release valve on the gauge/air release assembly by turning the knob on the back of the assembly fully counterclockwise (do not remove the knob). 7. Be sure to open any filter isolation valves that were installed in the system. 8. Ensure the backwash piping is open. Set the backwash valve handle to the “Backwash” position, if a multiport backwash valve is installed, and if a slide valve is used, turn the handle to unlock and pull fully upwards to the backwash position. 9. Stand clear of the filter and start the pump. When a steady stream of water starts to come out of the air release valve, close the valve. There will be a steady stream of water flowing out of the backwash valve piping. Continue to backwash until the backwash water is clear (three (3) to five (5) minutes). 10. Turn the pump off. 11. If the multiport backwash valve has a Rinse position do the following: a. b. c. Set the selector handle in Rinse position. Start the pump and run for 30 to 40 seconds. This helps settle the sand bed and removes fine particles in the bottom of the sand bed. Stop the pump. 12. Set the backwash valve handle to normal operation position, or to “Filter” position if a multiport backwash valve is installed. If using a slide valve, 13. Make certain all inlet and return lines to the pool are open to allow free movement of water from the pool and returning to the pool. 14. Completely open the air release valve on the gauge/air release assembly by turning the knob on the back of the assembly fully counterclockwise. Do not remove the knob. 15. Stand clear of the filter and start the pump. When a steady stream of water starts to come out of the air release valve, close the valve. 16. Ensure that the water is returning to the pool. The system is now in normal filtration mode. 17. After the pressure gauge has stabilized, turn the bezel ring so that the arrow next to the word clean aligns with the needle of the gauge. As the filter cleans the water and the sand begins to clog, the pressure will increase. When the needle of the pressure gauge aligns with the arrow next to the word dirty on the bezel, it is time to clean the filter (see Cleaning Instructions). This indicates an increased pressure of between 10 and 12 psi above original starting pressure. J. Replacement Kit Lists 1. The table on the next page is for your reference.
