5. Operating Instructions
5.1 Powering On/Off
Once plugged in, the fountain will automatically begin circulating water. To turn off, simply unplug the power adapter from the electrical outlet.
5.2 Water Flow Modes
The GIOTOHUN Cat Water Fountain offers two distinct water flow modes:
- Faucet Running Water: With the faucet attachment installed, water flows from the faucet, mimicking a tap. This mode is designed to attract pets who prefer drinking from running water sources.
- Fountain Running Water: Without the faucet attachment, water bubbles up from the center, creating a gentle fountain effect. This mode is often preferred by shorter pets or those who prefer a less direct stream.

5.3 Water Level Monitoring
The fountain features a transparent water level window with an LED light, allowing for easy monitoring of the water volume. Refill the fountain when the water level drops to prevent the pump from running dry.

To ensure optimal pump performance and longevity, clean it every 1-2 weeks:
- Remove the pump from the fountain.
- Remove the pump cover and the impeller cap.

6.3 Filter Replacement
The fountain uses a 4-stage filtration system. Replace the carbon filter every 2-4 weeks, and the sponge filter every 1-2 weeks, or more frequently if multiple pets use the fountain or if water appears dirty.
- Carbon Filter: Activated carbon removes bad taste and odor, and ion exchange resin softens tap water.
- Sponge Filter: Captures pet hair and larger impurities, and helps remove fine particles.
Replacement filters can be purchased by searching for "B0DFMBP2BJ" on Amazon.
