- 1). Place the filter canister base, a square ring with a beveled edge and a cutout section at the center for the ball canister to sit in, on the slab or ground you have prepared for it. Set the ball canister on its base.
- 2). Wrap the threads of the pressure gauge with a double layer of Teflon tape to waterproof it. Assemble the filter by screwing the pressure gauge on to the side of the big ball canister. Use a wrench for the last few turns to make sure it is tightened as far as it will go.
- 3). Insert the drain cap and screw on tight. Fill the canister tank half full with water.
- 4). Check to be sure all lateral rods are in good condition. All lateral rods must be positioned upward so they fit into the neck of the canister. Install the piping and interior pump assembly into the tank canister. Drop the lateral rods down into their sideways position at the bottom of the tank.
- 5). Place masking tape over the top opening of the center pipe leading into the canister so sand can't enter and clog it. Place the sand shield that comes with the filter kit over the taped pipe opening to provide a peak for the sand to flow over.
- 6). Open bags of sand and pour slowly into the canister until all laterals are covered. Hold the center pipe in place firmly while pouring, or have someone help you keep it steady. Keep the surface of the sand inside the tank level without moving the lateral rods or the center pipe.
- 7). Use silicone lubricant to oil the O-ring for the valve and put it on the valve. Remove the tape from the center pipe and place the multiport valve on top. Secure it with the O-ring. Place the secure clamp on the tank and valve. Position it carefully and tighten it down.
- 8). Wrap all valve ports with Teflon tape. Connect the pump valve to the discharge with a hose from the pump kit. Screw the thread adapter to the port to seal it thoroughly. Tighten with wrench, but be careful not to over-tighten it because this can crack the plastic or hoses.
- 9). Coat the inside of the adapter with primer. When dry, apply plumber's glue over the primer and insert a short section of pipe into the adapter. Twist to spread the glue over the pipe surface. Let set. Attach to the intake valve port. Create another adapter and attach it to the discharge pump port. Above-ground pools often use soft plastic hoses in place of PVC piping. Attach and tighten down clamps over holes.
