Blush the filters
Once you have your filter out, have the filters rinsed. You need to make use of a garden hose for the rinsing and strictly avoid using pressure washers. As you flush the filters, you need to be cautious in order to avoid damages to the filters. So, ensure you are maintaining an angle of 45 degrees.

Otherwise, you may use a TSP substitute. Lukewarm water and a cup of dishwasher detergent can be used. The dishwasher detergent for the machine is far different from the dishwashing for hand cleaning. You may, therefore, compare their capabilities and go for the one that suits you. Lastly, rinse the filters to have any stacked debris removed.
Clean the filter tank
While the filters are submerged in the TSP solution that can be your good chance to have the filter tank cleaned. Through the drain, now flush out the accumulated dirt.

Then, fill the filter housing with water. This is to enable the degreaser function, and you can use a wooden rod to stir and have it dissolved in water. Thereafter, now drain out the fluid and seal the tank to let the pump circulate.
Wash the filters using muriatic acid wash
For a perfect filter, make use of muriatic acid. Before you soak the filters in the acid, you need to make sure that no oils or cleaning solutions are stuck on the filters. This is to ensure that your filters are not damaged since permanent damages may occur.
If required, you’ll have to purchase another filter for replacement. Therefore always take precautions. The filters should remain submerged until the bubbling stops. Now you can take them off and rinse them with a lot of water. Make sure you use gloves and safety glasses.
Clean the seals
Just as you had the filters cleaned, their seals also need to be cleaned. They as well would be deteriorated even though usable. Once you have them cleaned, they need to be lubricated. Here you are advised to use silicone paste and strictly not grease.
This would help in sealing and also have them in a better condition. Additionally, silicone paste is of importance since leaks are avoided, and also you won't have to replace that.

If the need arises, you can as well lubricate the bolts for a perfect tightening. At this point, the filtration system is turned on. There's the need to open the valve responsible for releasing the excess air from the tank.
For you to know when the excess air is all released, the valve should remain open until when water flows out through the valve. If a need arises, you can have the filter pressure recalibrated. Finally, you have your filter cartridge in order!
Tips and Tricks
To maintain the pol filter cartridge, take precautions before dipping to any chemical. Always remember the chemicals are added to water and not having water added to the chemicals. This will keep the filter's condition in place and not alter it while being submerged in the chemical.
