Little Giant Pressurized Filter

Ease of filter upkeep means peak pond conditions. The Little Giant Pressurized Bio Filter with "grip-n-twist" handle lets you clean your pond filter sponge without having to remove the filter lid. This time-saving feature makes it virtually effortless to ensure proper filter operation. Workhorse performance delivers excellent biological and mechanical filtration. Mechanical filter sponge boasts high surface area to trap solid waste for pond water clarity. Bio-ball biological filter media allow the development of beneficial bacteria that break down toxic pollutants such as ammonia and nitrite. The result is a pond that's cleaner, clearer, and healthier for your pond inhabitants. Includes sponge media and bio balls, hose adapters, o-ring, hardware and full instructions. For ponds up to 2,400 gallons. Requires appropriately-sized pump and tubing, sold separately.

Filter assembly
• Bio-ball bags
• O-ring
• Owner's manual
• Hardware kit
• 1" hose adapters ( x 2)
• Handle ( x 1)
• Cap ( x 1)
• Large O-ring ( x 1)
• Replacement hinges ( x 2)

1. Remove the filter assembly from the carton.
2. Loosen the six latches and remove the cover from the tank.
3. Remove the bottom plate from inside the tank, leaving the white mesh grate in place.
4. Remove the bio-balls from their package(s) - separating any that have become stuck together. Place them into the bottom of the tank around the outside of the white grate.
5. Install the plate, knobs up.
6. Install Large O-ring. If using a lubricant, use water-based rather than oil-based.
7. Install the cover assembly and close all latches.
8. Install the handle.
9. Install the Small O-ring into the cap.
10. Install the cap onto the handle threads. HAND-TIGHTEN ONLY.
11. Install a hose adapter onto the IN and OUT fittings. NOTE: Ensure all gaskets are installed.
12. HAND-TIGHTEN ONLY unless leaks are present.

1. Decide on a suitable location to install the filter then bury it in the ground, as high as the latches if necessary.
2. Attach a flexible pipe or hose to the pump and connect it to the filter inlet (marked IN).
3. Attach a flexible pipe or hose to the filter outlet (marked OUT), and position this water outlet pipe as required.

Troubleshooting
If the filter fails to operate:

1. Check the pump discharge and tubing for kinks and obstructions. Flush out any built-up algae with a garden hose.
2. Troubleshoot the pump according to its owner's manual.

Maintenance
NOTE: When water pressure begins to decrease noticeably, clean both the pond pump and the filter.
NOTE: Do not use cleaning solvent, detergent, or tap water (which likely contains chlorine) to clean the filter or filter media. Use only pond water. Clean the filter thoroughly, externally and internally, twice a year.

1. Disconnect the pond pump and the filter from electrical power.
2. Remove the outlet hose from the outlet adapter and set the hose aside.
3. Remove the outlet adapter and the backwash cap, and swap their positions.
4. Connect a waste hose to the adapter on the backwash fitting.
5. Connect the pond pump to electrical power. This will dislodge and remove dirt in the filter and sponge.
6. Turn the handle several times to squeeze the sponge.
7. For more efficient flushing, try backwashing:
8. Disconnect the pond pump from electrical power.
9. Remove the inlet hose (not included) from the inlet adapter and set the hose aside.
10. Remove the inlet adapter and the cap on the outlet fitting and swap their positions.
11. Connect the inlet hose to the outlet adapter.
12. Connect the pump to electrical power and turn it on.
13. Turn the handle back and forth several times to squeeze the sponge.
14. Disconnect the pond pump from electrical power, return all parts to their original configuration, connect the pond pump to power, and plug in the filter power cord OR proceed to the next section.

1. Disconnect the pond pump from electrical power.
2. Unlatch the six latches and remove the filter lid.
3. Clean the inside of the filter canister.
4. Remove the sponge and bio-balls (leaving the white mesh grate in place) and clean them in a container filled with pond water (not tap water). If the sponge shows signs of damage/wear, replace it.
5. Return all parts to their original configuration, connect the pond pump to power, and plug in the filter power cord.

General Information
The Little Giant Pressurized Filter is designed to filter the water in ponds and water gardens and uses the following types of filter media:

• Mechanical Filter Media: High surface area sponge media traps solid waste, maintaining clean and healthful water for both fish and plants.
• Biological Filter Media: Inert media (bio-balls) offer a large surface area and high porosity that allow the development of beneficial bacteria, which breaks down pollutants such as ammonia and nitrite.
