Hayward DE4820 ProGrid D.E. Pool Filter Instruction Manual

1. Prodott Aktarview

The Hayward DE4820 ProGrid D.E. Pool Filter is engineered to deliver superior water clarity and efficient filtration for various pool and spa applications. This vertical grid D.E. filter features a 'service-ease' design, simplifying maintenance and ensuring reliable operation. Constructed from durable, glass-reinforced copolymer, the filter tank is built for longevity in demanding pool environments.

Key features include an inlet diffuser elbow that ensures even distribution of Diatomaceous Earth (D.E.) to the filter grids, and a heavy-duty, one-piece flange clamp for secure assembly and convenient access to internal components without disturbing plumbing connections. The filter also incorporates 2-inch full-flow internal piping for reduced resistance and maximum performance.

2. Setup u Installazzjoni

Proper installation is crucial for the optimal performance and longevity of your Hayward DE4820 ProGrid D.E. Pool Filter. Follow these steps for setup:

1. Spakkjar u Spezzjoni: Carefully remove all components from the packaging. Inspect the filter tank, grids, and all accessories for any signs of damage during shipping.
2. Poġġiment tal-filtru: Select a firm, level surface for the filter installation. Ensure there is adequate clearance around the filter for future maintenance and servicing.
3. Konnessjonijiet tal-plaming: Connect the filter to your pool's existing plumbing system. The filter is designed with 2-inch full-flow internal piping. Use appropriate fittings and sealants to ensure all connections are secure and watertight. Note: A control valve (e.g., multi-port valve) is not included with the filter and must be purchased and installed separately.
4. Initial D.E. Charge: After all plumbing is complete and the system is ready, the filter requires an initial charge of Diatomaceous Earth (D.E.). For the DE4820 model, 6 pounds of D.E. are required. Mix the D.E. powder with water to create a thin slurry. With the pool pump running and the filter valve set to 'Filter', slowly pour the D.E. slurry into the pool skimmer.
5. Air Relief: During initial startup and whenever the system is opened, air may become trapped inside the filter. Utilize the high-capacity, rapid-release manual air relief valve located on the top of the filter. A quick quarter-turn of the lever will release trapped air. Close the valve once water begins to spray out.

3. Istruzzjonijiet Operattivi

Once installed and initially charged with D.E., operating your filter is straightforward:

1. Starting the Filter: Ensure all plumbing valves are in the correct position for filtration (e.g., filter valve set to 'Filter'). Turn on the pool pump.
2. Monitoraġġ tal-Pressjoni: Observe the pressure gauge on the filter. Note the initial pressure reading when the filter is clean and freshly charged with D.E. This is your baseline 'clean filter pressure'.
3. Operazzjoni normali: Allow the filter to run for the recommended duration to circulate and clean the pool water. The duration will depend on your pool size, usage, and environmental conditions.
4. Backwashing Indication: The filter requires backwashing when the pressure gauge reads 8-10 PSI above your initial clean filter pressure. This indicates that the D.E. and trapped debris are reducing water flow.

4. Manutenzjoni

Regular maintenance ensures your filter continues to provide clear water and operates efficiently.

4.1. Backwashing Procedure

Backwashing removes accumulated D.E. and debris from the filter grids:

1. Itfi l-Pompa: Always turn off the pool pump before changing the filter valve position.
2. Set Valve to Backwash: Set your multi-port control valve to the "Backwash" position.
3. Filtru tal-ħasil b'lura: Turn on the pump and backwash until the discharge water runs clear (typically 1-2 minutes).
4. Itfi l-Pompa: Turn off the pump again.
5. Laħlaħ (jekk applikabbli): If your valve has a "Rinse" setting, set the valve to "Rinse" and run the pump for 30-60 seconds to flush any remaining D.E. from the lines.
6. Itfi l-Pompa: Itfi l-pompa.
7. Return to Filter: Set the control valve back to the "Filter" position.
8. Recharge D.E.: Recharge the filter with the appropriate amount of D.E. (6 lbs for DE4820) by mixing it into a slurry and adding it through the skimmer while the pump is running.

4.2. Periodic Grid Cleaning

Over time, D.E. and fine debris can become embedded in the filter grids, even with regular backwashing. A deep cleaning is recommended periodically (e.g., seasonally or if consistently high pressure is observed after backwashing).

1. Turn Off Pump and Relieve Pressure: Turn off the pump and ensure all pressure is relieved from the filter tank using the manual air relief valve.
2. Open Filter: Open the heavy-duty, one-piece flange clamp that secures the tank top and bottom. Carefully remove the top half of the filter tank.
3. Remove Grids: Carefully lift out the filter grid assembly.
4. Clean Grids: Thoroughly rinse the filter grids with a garden hose to remove all D.E. and trapped debris. Inspect the grids for any tears, holes, or damage. Replace damaged grids as necessary.
5. Clean Tank Bottom: Remove the drain plug at the bottom of the filter tank and wash out any accumulated debris from the bottom half of the shell.
6. Erġa' arma: Reassemble the filter, ensuring the grid assembly is correctly seated and the flange clamp hija mwaħħla sew.
7. Recharge D.E.: Recharge the filter with the appropriate amount of D.E. (6 lbs for DE4820) as described in the backwashing section.
