Things You'll Need
2 large buckets
Wide mouth pliers
Replacement filter sand
While filtering your pool water, the sand in the Jacuzzi Laser Sand Filter can get clogged and filled with debris. Fortunately, you can disassemble the pool filter to access the used sand. You must use a special filter sand blend specifically for the Jacuzzi Laser Sand Filter, not sandbox sand. Keep the filter sand dry so it is able to filter properly. If well-maintained with new replacement sand, the Jacuzzi Laser Sand Filter will keep your swimming pool clean.
Unplug the Laser Sand Filter unit power cord from the outlet before removing and replacing the filter sand.
Loosen and unscrew the union nuts on the side of the hose with the wrench and disconnect the hose from the side of the filter tank. The hose may still be full of water, so drape it in a bucket to catch the water.
Unscrew the six dial valve bolts with the screwdriver that hold the dial valve on top of the filter tank. Carefully lift up the dial valve and set it aside.
Take the O-ring off of the top of the filter tank. Reach into the filter tank and take out the entire filter basket and standpipe cover assembly. Now you can access the sand, which is mixed with water.
Pour out the used sand and water mixture into a second bucket and discard. Carefully place the filter basket and standpipe cover assembly back into the filter tank.
Fill the filter tank 1/2 full of water. Add the replacement sand. The L160 takes 140 lbs., the L190 200 lbs., and the L225 takes 250 lbs.
Replace the O-Ring on the top of the standpipe cover. Position the dial valve on top and rotate until the "Pump" valve inlet is in line with the pump outlet opening. Screw in the dial valve hex bolts. Screw on the hose and tighten the union nut.
Always unplug the filter before disassembling.
