Operation - Hayward HCF7030C Manual

3. Starting the Pump and Filter System
WARNING
3.1 Before Starting the Pump
1. Use ONLY Hayward clamp system components; DEX2421JKIT clamp system, DEX2421J2 nut/bolt
assembly, DEX2422Z2 metal reinforced seal. Non-Hayward clamp components may fail in use and
cause explosive component separation. Verify that 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. Using a ¾"
socket on a torque wrench, torque clamp nut to 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)
2. Close filter drain. NOTE: Filter plug requires an o-ring seal. (See Fig 4)
3. Open all system valves to allow water from the pool to the filtration system and from the filter to
return to the pool.
4. Place the manual air relief valve in OPEN position. (See Fig 2)
3.2 Starting the Pump
1. When starting system pump, do not stand over or near filter. If water leakage appears at 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 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.

4.1 Filtering
WARNING
Filtration starts as soon as 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 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.
4.2 Maintaining Your Filter
WARNING
WARNING: This product should be installed and
serviced only by a qualified pool professional.
FILTER DISASSEMBLY INSTRUCTIONS
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
flow to the filter.
3. The manual air relief valve must be placed in the
OPEN position. (Fig 6)
4. Remove filter drain plug (Fig 4) and drain water
from filter.
5. Using 3/4" wrenches or hex sockets, loosen and
remove the clamp nut and the clamp bolt. (Fig 5)
6. Holding both ends of the filter clamp carefully
spread the clamp ends. Remove the clamp by lifting over the upper filter body. Do not to drop
the clamp during removal, because the clamp could be damaged. Do not strike the clamp with
metal tools as they can damage the clamp.
7. Lift off upper filter body. Do not use the pressure gauge to lift the upper filter body.
