Hayward Pool Pump Filter
Replacement Guide
How to change the cartridge style water
filter element in a Hayward brand pool pump with the part number.

 Pleatco Pure Brand |
 Cartridge Filter Element |
| This home
maintenance tutorial was specifically written to assist owners of the
Hayward Star-Clear II pool filter in changing the cartridge filter element. Owners of other Hayward pool filters such as the SwimClear, Star Clear, DEP 500, ProGrid, ProSeries and Perflex may also find these DIY instructions to be helpful. The OEM (original equipment manufacturer) part number for this Star-Clear II is Hayward C-800-RE. I chose to buy the compatible replacement Pleatco PA80 cartridge style water filter. No tools are required to access and replace the filter. |

 Filter Part Number |

 Pool Filtration Timer |
| The first step is
to open the timer box. Then flip the "ON / OFF" switch to the "OFF" position. |
||
 Turn "OFF" Pool Pump |
 Pool Filter Housing |
 Loosen Lid Clamp |
| After you hear the
pool pump turn off, you can slowly turn the "+" shaped handle on the top of
the filter lid clamp in the counterclockwise direction. An alternative method for releasing the pressure is to loosen the small pressure relief valve on the cap opposite of the PSI gauge. Allow any residual pressure in the filter housing to dissipate. |
||
 Release Pressure |
 PSI Gauge - 0 PSI |
 Pull Out Clamp Rod |
| Make sure the PSI
reading on the pressure gauge on the filter cap is at zero. Continue loosening the filter cap clamp in the counterclockwise direction until you can lift it out. |

 Threaded Rod End |
 Set Aside Clamp Rod |
 Pull Off Filter Cover |
| Remove the metal
rod from the hole in the center of the black plastic filter cap. Set the clamp rod aside in a safe place. Carefully pull the black plastic filter cap off the top of the housing. |
||
 Set Aside Filter Cap |
 Old Filter Exposed |
 Lift Out Old Filter |
| Gently set the
filter cap aside in a safe place. Carefully lift the old filter straight out of the housing. |
||
 Inspect Rubber O-Ring |
 Old Filter Removed |
 Lower In New Filter |
| Inspect the rubber
o-ring gasket on the top of the filter housing. If the rubber is torn, discolored or damaged, it should be replaced with a new gasket. The part number for the Star-Clear II head rubber o-ring gasket is Hayward CX800F. Gently lower the new filter straight down into the housing. |
||
 New Filter Installed |
 Replace Plastic Cap |
 Insert Threaded Rod |
| The new filter
should be just about flush with the rubber o-ring gasket on the housing. Lower the plastic cover back into place. Make sure the filter cap is fully seated and flush with the housing. Carefully insert the threaded rod into the hole in the filter cap. Try to avoid damaging the new filter element when you lower in the metal rod. |
||
 Tighten Filter Cap Clamp |
 Filter Cover Secured |
 Hayward Star Clear II |
| Tighten the handle
on the clamp rod in the clockwise direction until it is snug. The clamp rod should be tightened to about 1/4 to 1/2 turn past finger tight. Try to avoid over tightening the clamp to prevent from cracking the plastic cap. |
||
 OEM Filter C-800-RE |
 Filter Change Complete |
 Flip Switch To "ON" |
| Double check that
the filter clamp is tight. Move the switch to the "ON" position and listen closely. If you hear any strange sounds such as hissing or you see any water leaking, immediately turn off the pump. Check the filter head for any cracks or damage. If you need to replace the filter cap on your Star-Clear II, the part number is Hayward CX800C. |

 Pool Pump Turned On |
 24 Hour Dial Time Switch |
 Pool Pump Controls |
| Observe the pump
and filter housing for at least a minute to see if there are any leaks or
odd noises. Be sure to write down the filter change in your pool filtration system's service records. Please check out all of my
