General Information

Your Hayward HCF cartridge filter combines superior water filtration with ease of operation and totally
corrosion-resistant construction. With filtration ratings to 9000 gallons (34,000 liters) per hour, they are
designed for continuous or intermittent operation, for installation above or below the pool water line, for
fresh or salt water swimming pools or spas. HCF filters utilize multiple reusable, reinforced polyester filter cartridge elements to provide a high degree of water clarity and long filter cycles with minimum care.

Installation

1. The filter system should be installed on a level concrete slab or other rigid base. Select a well-drained and vented area, one that does not flood when it rains.
2. Position the filter so that the piping connections and winter drain are convenient and accessible for operation, service, maintenance, and winterizing.
3. Position the filter body such that all operations and safety labels are visible.
4. Position the filter so that filter will drain by gravity.
5. If practical, place the pump and filter in the shade to shield them from continuous, direct heat from the sun.
6. Connect the pool suction plumbing from the skimmers and pool suction outlets at the pump inlet port.
7. Connect the pump discharge (pump OUTLET) to the top port of the filter (filter INLET).
8. Connect the bottom filter port (filter OUTLET) to the pool return plumbing lines.
9. Do not locate pump controls over or near the filter.
10. Verify water discharge from the manual air relief valve(MAR) is directed away from electrical devices.

Starting the Pump and Filter System

1. Use ONLY Hayward clamp system components: DEX2421JKIT clamp system, DEX2421J2 nut/bolt
   assembly, DEX2422Z2 metal reinforced seal.
2. Non-Hayward clamp components may fail in use and cause explosive component separation. Verify that the upper and lower filter bodies are properly secured with the filter body clamp. Never rely on hand-tightening the clamp nut to the clamp bolt.
3. Using a ¾” socket on a torque wrench, torque the clamp nut to the clamp bolt to 150 inch-lbs. (See Fig. 1) Verify that the filter manual air relief body is in the LOCK position, and no filter components are missing, damaged, or not genuine Hayward components. (See Fig. 2)
4. Close the filter drain. NOTE: Filter plug requires an o-ring seal. (See Fig 4)
5. Open all system valves to allow water from the pool to the filtration system and from the filter to return to the pool.
6.  Place the manual air relief valve in the OPEN position. (See Fig. 2)

Starting the Pump

1. When starting the system pump, do not stand over or near the filter. If water leakage appears at the filter tank clamp, immediately turn off all system circulation pumps and all electrical power. Do not return to the filter until all water leakage has stopped. Reassemble the clamp system per the instructions on page 7 in this owner’s manual to stop the leak.
2. Return to filter to CLOSE manual air relief valve only when a steady stream of water (not air or air and water mix) is discharged from the manual air relief valve.

Manual Air Relief Valve

1. Turn off all system circulation pumps and all electric power on the equipment pad.
2. Set all system valves in a position to prevent water from flowing to the filter.
3. The manual air relief valve must be placed in the OPEN position.
4. Wait until all water leakage has stopped.
5. Grasp the MAR body at the flats, turn the MAR counterclockwise until the indicator on the MAR flange is aligned with the “UNLOCK” position on the upper filter body.
6. Pull straight up to remove the MAR. A slight rocking motion may help.

Re-Installation of the Manual Air Relief Valve

1.  Check the o-ring seals, replace as needed.
2. With a clean cloth, wipe the paper filter body and the o-ring groove. Remove all dirt and debris.
3. Align the notch in the MAR Flange with the HAYWARD HCF7030C HCF Cartridge Filter notch on top of the upper filter body.
4. Press the MAR straight down into the upper filter body.
5. Turn the MAR clockwise until the indicator is aligned with the “LOCK” position on the upper filter body.
6. Verify the MAR discharge points are away from all electrical connections.

Body and Clamp Re-Assembly

1. Place the metal reinforced seal on the lower filter body. (Fig 4) Place the upper filter body on the metal reinforced seal and the lower filter body in a position that allows all operation and safety labels to be clearly visible and the upper filter body to be centered on the lower filter body. Press down firmly and evenly on the upper filter body to seat the seal. (Fig 7)
2. Replace the filter clamp around the upper and lower filter bodies. Hold the clamp ends to position the clamp on the filter bodies with the clamp ends adjacent to the safety and operation labels on the filter bodies. (Fig 7)
3. Insert the lamp bolt through the clamp ends and thread the clamp nut onto the clamp bolt with the rounded end of the nut (Fig. 8) towards the ends of the clamp.
4. Never rely on hand tightening of the clamp nut to clamp the bolt. Using a 3/4” socket on a torque
   wrench, torque the clamp nut to the clamp bolt to 150 inch-lbs. (Fig 9)
5. Follow Operation Instructions for “Starting the Pump and Filter System” (Page 5).

Operation

Filtration starts as soon as the flow is steady through the filter. As the filter removes dirt from the pool water, the accumulated dirt causes a resistance to flow. As a result, the gauge pressure will rise and the flow will decrease. When the pressure rises between 7 and 10 psi (.49 – .69 bar) above the starting pressure, or when the flow decreases below the desired rate, clean or replace the filter cartridge elements.

Once your filter is running and there is a pressure reading, line up the green arrow with the current reading. (See Fig. 3) When the pressure rises to or above the red or second arrow, it is time to clean or replace your filter cartridge elements.

By recording the initial starting pressure (with clean filter elements), a determination can be made when the filter cartridge elements should be replaced rather HAYWARD HCF7030C HCF Cartridge Filter than cleaned.

After the filter elements have been cleaned and reinstalled, if the starting pressure is higher than 6 PSI above the starting pressure with the new filter cartridge elements, the filter cartridge elements should be replaced the next time the gauge arrow reaches the red arrow.
