If you have a pool heater, the pool filter will release water to the heater before going to the chlorinator. Step 3 The pool filter should be installed on a level concrete slab not more than 6 feet above the pool water level. Position the pool sand filter so that the piping connections, multiport valve and drain are convenient and accessible for operation and maintenance.
Place the filter next to pump. Step 4 Before you connect the pool sand filter into the piping system, you have to assemble the filter. If the threads aren't prepared, wrap them with two layers of Teflon tape.
Start in a clockwise direction at the first thread with a half-width overlap for the full length of the thread. Be careful when screwing the gauge on. Use a wrench on the square nut on the final turns. Please click here to view teflon tape.
Step 5 Make sure drain cap is securely in place. This will help protect the laterals. Step 7 Next you will be installing pipe and lateral assembly inside the tank.
Separate the valve from the pipe and lateral assembly. Also make sure the 10 laterals at the end of the pipe are rotated up.
They have to be in their up position to fit through the hole in the top of the tank. These laterals are somewhat fragile. Ensure that none are cracked or broken. Place the pipe and lateral assembly inside the tank. Step 8 After the lateral assembly is inside, carefully rotate the 10 laterals 90 degrees in their down position. Step 9 Make use the pipe is centered in the opening.
Tape the top of the pipe to prevent sand from entering and clogging the laterals. Step 10 The sand filter package comes with a cardboard sand shield. Place this over the pipe and within the opening. Step 11 Pour sand carefully into the pool sand filter until laterals are fully covered.
For this unit 3 bags should leave at least 6" space between the top of the sand and the top of the filter. Level sand as you pour and make sure the center pipe remains centered in the opening. Be careful when leveling the sand that you do not lift the pipe and lateral assemble up off the bottom of the tank. You will not be able to push the pipe back down without causing the laterals to rotate up. Please click here to view the magic lube o ring lubricant. Step 13 Remove tape from top of pipe.
Slip the Multiport control valve onto the central pipe - check the O-ring to ensure it is positioned correctly. Step 14 Install clamp around the tank and valve flange. Loosely tighten clamp so that the valve can be rotated on the tank for final positioning. Step 15 The next step is to connect the "PUMP" port of the multiport valve to the discharge side of the pump. You will need to screw a straight thread adapter purchased at a hardware store into the "PUMP" port.
To help seal this connection wrap two layers of Teflon tape the adapters. Do not over tighten or you cause the joint to fail. Step 17 Cut a short piece of pipe and glue it to the adapter. Make sure the pipe and inside of the adapter are clean. Gluing is a two-step process. First apply a thin but even coat of purple primer on each surface to be joined: the outside of the pipe and the inside of the adapter.
After the primer dries, apply a thin even coat of glue to both surfaces. Wait 30 seconds for the glue to set. Step 18 Glue on a union to facilitate future maintenance on the pool sand filter or pump. In years you will have to disconnect the multiport valve from the tank to change the filter sand. A union will save you from having to cut it out of the piping.
Step 19 Screw another adapter into the discharge side of the pump then add piping and elbows required to connect the filter and pump ports. In a basic system this connection will probably be to the Chlorinator. Also add a union to this line for future maintenance. Note: This picture does not show the water hose.

Tap around the clamp with the screwdriver handle as you are tightening the clamp to help seat the clamp properly. Place vinyl protector caps over the ends of the screws. Step 23 Your new pool sand filter should now be ready to operate. Make sure that your waste line is rolled out to where you want to dump the pool waste water.
Step 25 Prime and turn ON the pool pump. Be sure that you have at least one suction and all discharge lines open. Step 26 Run the pool pump for 2 minutes after you have a steady flow of water out the waste line after the pump is fully primed. This will flush all the impurities or fine sand particles out of the sand media. Step 28 Turn the pump back ON and run until the water in the sight glass is clear.
This should take no more than 1 minute. Step 30 Turn the pool pump ON. This is the normal operating mode for your filter. Note the pressure gauge reading. This is your clean sand filter pressure. As contaminates build up and clog your sand the pressure will climb. When it is psi above your clean filter reading, it's time again to backwash your filter. Add a Comment.
