How to Replace the Filter in PETLIBRO PLWF115

Quick Answer

1. Turn the fountain off.
2. Remove the water tank from the base and pour out water if needed.
3. Soak the new flat filter in a clean bowl for five minutes, then rinse it.
4. Remove the top lid, optional spout, and filter lid.
5. Remove the used flat filter.
6. Replace the foam filter on the pump.
7. Install the new flat filter and align its hole with the water pipe.
8. Fasten the tray, replace the lid, refill, restart, and confirm smooth water flow.

Items Needed

• New flat replacement filter
• New pump foam filter
• Clean bowl
• Tap water for soaking and rinsing
• Fresh water for refilling
• Small cleaning brush for optional pump cleaning

Before You Start

Turn the fountain off before removing parts.

Remove the tank from the base and pour out water if needed.

Soak the new filter in a clean bowl to avoid introducing loose filter dust into the fountain tank.

Replacement Instructions

Step 1: Remove the Lid and Old Filter

Lift off the top lid. If your fountain uses the optional spout, remove the spout first. Remove the filter lid, then lift out the used flat filter.

Step 2: Replace the Foam Filter

Pull the old foam filter off the pump. Fit the new foam filter into the pump groove so it sits flush, then align the pump with the slot in the tank.

Step 3: Install the Flat Filter and Align the Pipe

Place the soaked and rinsed flat filter under the lid area. Make sure the filter lies flat and that the water pipe passes through the water tray and filter openings.

Step 4: Reassemble and Restart

Fasten the snap lids, reinstall the filter lid, refit the spout if used, add water, place the tank back onto the base, and switch the fountain on.

Maintenance Tips

• Replace the flat filter and foam filter at least once every two weeks.
• Clean the pump and fountain at least once every two weeks.
• When changing filters, it is a good time to remove the foam filter, pump cover, and impeller cover, clean the pump parts, rinse them, and reassemble the pump.
