FILTER OPERATES UNDER HIGH PRESSURE.
When any part of the circulating system, (e.g., clamp, pump, filter, valve(s), etc.), is serviced, air can enter the system and become pressurized.
Pressurized air can cause the lid to separate which can result in severe injury, death, or property damage.
To avoid this potential hazard, follow these instructions:
1. Before repositioning valve(s) and before beginning the assembly, disassembly, or adjustment of the clamp or any other service of the
circulating system: (A) Turn the pump OFF and shut OFF any automatic controls to ensure the system is NOT inadvertently started
during the servicing; (B) open the manual air relief valve; (C) stand clear of the filter; (D) wait until all pressure is relieved.
2. Whenever installing the filter clamp FOLLOW THE FILTER CLAMP INSTALLATION INSTRUCTIONS EXACTLY.
3. Once service on the circulating system is complete FOLLOW SYSTEM RESTART INSTRUCTIONS EXACTLY.
4. Maintain circulation system properly. Replace worn or damaged parts immediately, (e.g., clamp, pressure gauge, valve(s), o-rings, etc).
5. Be sure that the filter is properly mounted and positioned according to instructions provided.
Operating the filter system without filter internal components installed can allow air to accumulate within the filter. Pressurized air can cause
the lid to separate which can result in severe injury, death or property damage. Always operate filter system with filter internal components
installed. To prevent equipment damage and possible bodily injury and/or property damage, always turn the pump off before changing the valve positions.
Please follow all manufacturers' posted instructions, warnings and cautions when using pool or spa sanitizers, and/or other chlorine replacement
treatments.
When to Clean the Filter
Properly monitoring and cleaning the filter will prevent
avoidable repairs and maintenance.
Clean your filter when pressure reads between 8-10 psi
higher than the "Original Starting Pressure" recorded
in Table 3 on the previous page, or when significant
reduction in flow is noticed. The pressure reading
increases as it filters dirt from your pool. This build up
of pressure will vary due to different bathing loads,
temperature, environmental conditions, etc.
Backwashing the Filter
Most effective cleaning of the filter cartridges
requires disassembly and hand cleaning. However,
for convenience and to extend the interval between
cleanings the FullFloXF
®
Filter can be equipped with an external backwash valve.
1. Turn the entire pool/spa system off at the circuit
breaker.
2. Open the HiFlow™ Manual Air Relief Valve and wait
until all pressure is released from the system. Never
attempt to assemble, disassemble or adjust the filter
clamp while there is pressure in the filter.
3. Turn skimmer to full skim position and close main
drain line.
4. Remove pump lid and clean basket. Replace the
basket and secure lid.
5. Position the valve to BACKWASH.
6. Open the manual air relief valve until it snaps into the
full open position to release trapped air in the filter
(this only requires a quarter turn counter-clockwise).
7. Stand clear of the tank, then start the pump.
8. Close the manual air relief valve after a steady
stream of water appears.

9. When water flows clear in the sight glass or
discharge line, shut the pump off. This should take
about three minutes.
Note: Backwashing is most effective when the filter is
operated at the maximum listed flow rate.
10. If the filtration system includes a separation tank, refer
to the the separation tank's manual for instructions on
cleaning the tank.
11. Rotate the valve handle back to FILTER.
12. Restart system, refer to Start-Up Instructions on
page 8.
13. Proceed with operation and precoat filter with the
required amount of D.E.
Refer to Table 2 on page 6, under Preparing
Diatomaceous Earth (D.E.).
NOTE: If the starting pressure after backwashing the filter or cleaning the
cartridges indicates 8 to 10 psi higher than the original starting pressure
as defined in Table 3 on page 8, the filter cartridges must be manually
cleaned. Refer to Manually Cleaning the Filter Cartridges on page 10 for
instructions.
NOTE: Filter waste and D.E. are trapped by the heavy-duty double lined
Separation Tank bag. Contents are to be placed in a waste or trash
container, clean the bag and re-insert in the Separation Tank. DO NOT
LEAVE THE TANK BAG EXPOSED IN THE SUN. The manufacturer
cannot assume any responsibility for torn, or damaged bags, if left in the
sun to dry.
