Removal and cleaning of Hayward DE filter screens (2023)

This guide shows the steps required for removal and cleaning.Filtergiter Hayward DE. Periodically remove dirt and debrisHayward DE Filter. This process can be performed at three levels: 1- by backwashing the filter; 2- removing and cleaning the grid assembly; or 3- removing and cleaning each assembly mesh.

1.COLLECTED TOOLS - Gather the necessary tools: a socket wrench, a large wrench, two small open end wrenches, silicone or Teflon based lubricant, a rubber mallet, a face mask and a cleaning cloth.

2.TURN OFF - If the pump is on, turn it off at the circuit breaker or preferably at the breaker box.

3.OPEN AIR RELIEF VALVE - Relieve pressure in the filter tank by opening the air pressure valve on the back of the gauge.

4.REMOVE drain plug - Remove the drain plug from the drain filter. Insert a screwdriver into the hole in the plug, which will act as a handle if the plug cannot be removed by hand.

5.SEE CLAMP ASSEMBLY - The tank of this Hayward DE filter is divided into an upper and lower section held together in the center by a clamp assembly. To open the tank, remove the clamp assembly.

6.REMOVE BOTTOM NUT AND BOLT - The clamp assembly is secured with a nut and bolt. Place the socket wrench on the head of the bolt and the wrench on the nut and unscrew the bolt. - anticlockwise.

7.REMOVE HEX NUTS AND BOLTS - Remove the set screw after removing the nut.

8.FLOOSE CLAMP - Clamp assembly is tight. Tap one end of the clamp with a rubber mallet to loosen the clamp assembly.

9.REMOVE CLAMP - Remove clamp assembly from tank. Note that there are two pivots or hinges on the clamp to make it easy to remove or replace the clamp.

10.TANK HALF DISASSEMBLY - Both halves of the filter tank can still be assembled together. Take a rubber mallet and gently tap the top of the top tank.

11.LIFTING THE TOP HALF - Lift the tank top section directly off the truss frame.

12.SEE NETWORK ASSEMBLY - This is a photo of the top half of the grille assembly. Note the 8 DE powder coated grids.

13.ASSEMBLE THE HOSE - To reduce the weight of the grid, screw the grid to remove most of the DE dust.

14.REMOVE GRID ASSEMBLY - Lift grid assembly out of filter tank. When lifted, the header tube on the side of the grid assembly must separate from the bottom tube of the tank. Pay attention to their orientation so that you can connect them when replacing the grid assembly.

15.REPLACE THE NET - Place the mesh assembly on the ground and rinse again. Spray the inside and outside of the connector to remove as much of the old DE dust as possible.

16.REMOVE SAFETY NUT AND WASHER - The upper collector is secured with a single nut on a bolt that runs through the center of the grid assembly. To remove the top nut and washers, grasp the screw at the bottom of the grid assembly.

17.LOWER SAFETY SCREW - Turn the grid assembly on its side and secure the lower bolt by removing the upper bolt. Remove the top nut and washers.

18.FIND A PARTIAL MESH - This net set consists of 8 nets, one partial or short net and 7 full nets. The partial grid has been shortened to accommodate a manifold that fits into the side of the grid assembly. Locate where the partial grid is before removing the top collector. It will be located under the arm of the Top Manifold with the inscription "Short Element Here". When replacing the upper collector, it must match the same configuration.

19.REMOVE THE UPPER DISTRIBUTOR - Remove the upper divider from the 8 grids. The top collector has 8 ports that line up with the ports at the top of each grid. Note: In this photo, the partial grid is still attached to the upper manifold and must be carefully removed.

20.CHECK THE MANUFACTURER FOR DAMAGE - Inspect the upper manifold for cracks around the manifold ports and piping connections. Replace upper collector if damaged.

21.CHECK SEPARATOR TUBE FOR DAMAGE - Check the header tube that runs from the side of the tank and connects to the upper header. Replace if damaged. Also check the O-ring at the top of the tube for cracks and wear.

22.REMOVE PARTIAL GRILL - To avoid confusion over the location of individual grates, many people remove them one at a time for cleaning. After removing the top catcher, a second person may be needed to hold the grates while pulling them out one at a time. We start with a partial mesh, but you can choose any other starting point. Pull the partial handle up from the bottom guide. Notice how the grid snaps to the bottom so you can replace it the same way.

23.CLEAN PARTIAL GRILL - Clean the partial grate with a garden hose. Rinse the partial grill with a garden hose.

24.CHECK PARTIAL MESH - Examine the mesh for signs of tears or damage to the plastic core that pierced the fiber. Replace the mesh with a new one if necessary.

25.REPLACING THE PARTIAL GRID - Place the cleaned or new grille in its place. Make sure the partial grill is properly seated at the bottom.

26.REMOVE FULL GRILL - Remove the complete grille from one side of the partial grille by pulling it away from the grille assembly. Notice how the grid snaps to the bottom so you can replace it the same way.

27.CLEANING the complete grill - Rinse the entire grill with a garden hose.

28.CHECK ALL MESH - Inspect the mesh for signs of tears or degradation in the plastic core that has punctured the fiber. Replace the mesh with a new one if necessary.

29.REPLACE THE COMPLETE GRID - Place the cleaned or new grille back on its seat. Make sure the partial grill is properly seated at the bottom.

30. REPEAT FOR THE REMAINING 6 STICKS - Remove the stitch one at a time, repeat the last four steps for each of the remaining 6 full stitches.

31.RESET THE TOP DISTRIBUTOR - Place the top divider on top of the rails. Make sure each grid is securely connected to one of the 8 collector ports. Make sure the collector connection labeled "Short Piece Here" is aligned with the partial mesh.

32.ADJUST THE COLLECTOR FASTENING NUT - Place the grid assembly on its side and while holding the lower bolt, tighten the upper nut and washers to secure the upper collector.

33.DRIVE THE TANK BOTTOM HOSE - Loosen the tank bottom hose. Water and dirt should flow out of the drain.

34. REMOVE AND CHECK TANK O-RING - Remove the tank O-ring located on the bottom edge of the tank. Check for cracks and wear. Replace tank sealing ring if necessary.

35.CLEAN O-RING SEAT - Clean the groove where the tank O-ring is located.

36.REPLACE TANK O-RING - Replace the tank O-ring.

37. LUBRICATE TANK O-RING - Lubricate the top of the tank O-ring with silicone orTeflon-based Graxa.

38.REPLACING THE GRILL ASSEMBLY - Drop the grille assembly back into the bottom of the tank. Make sure the header tube sections line up.

39.HOSE OUTLET THROUGH THE TOP OF THE TANK - Clean the top part of the tank.

40.REPLACING THE TANK TOP - Place the tank top back on the bottom. Make sure the pressure gauge is positioned in a visible position.

41.SEAT TOP - Press the tank top in a rocking motion to help put it in place.

42.REPLACE Camp Assembly - Replace Camp Assembly, starting with the rear third and bending both sides to meet the front. Make sure the clamp is placed on both the top and bottom edge of the tank.

43.REPLACING THE CLAMP BOLT AND NUT - Insert the bolt and begin tightening the nut on the end of the bolt. Stop to adjust the clamp assembly when the nut becomes difficult to turn.

44.ADJUST THE CLAMP ASSEMBLY - Gently wrap the clamp assembly around its perimeter to tighten it more tightly. Retighten the screw assembly. Make this adjustment several times. Make sure the last few turns are tight, but don't overtighten the bolt assembly.

45.REPLACE drain plug - Replace the drain plug at the bottom of the filter tank.

46.CHECK MPV IN FILTER POSITION - Make sure the multiport valve (MPV) on the filter is set to FILTER mode.

47.PUMP ON - Turn on the pool pump and wait until it reaches the flood level.

48.CLOSE RELIEF VALVE - The air relief valve must be open to initially release air from the top of the filter. Close this valve when a steady stream of water comes out of the end of the valve.
