Setup and Assembly
The PetSafe Outlast Fountain is designed for quick and effortless assembly. Follow these steps to set up your fountain:
- Unpack Components: Carefully remove all parts from the packaging.
- Rinse Parts: Rinse all fountain components (excluding the power adapter and motor unit) with warm water before first use.
- Assemble the HydroSpin Unit: Place the HydroSpin cone mechanism into the designated slot within the fountain's main body. Ensure it is securely seated.
- Insert Filter: Place the Ion-X filter into its compartment. The filter should fit snugly.

Operating Instructions
Once assembled and plugged in, the PetSafe Outlast Fountain will begin operating automatically. The HydroSpin technology will circulate water, providing a continuous flow for your pet.
- Water Flow: The unique cone mechanism cycles 90 oz of water into the drinking bowl, ensuring fresh water is always available.
- Intelligent Sensors: The fountain is equipped with intelligent sensors that automatically slow water flow at night to reduce noise and conserve energy. It also shuts off when water levels are critically low to protect the motor.
- LED Indicator: An integrated LED light provides visual cues for fountain status. It indicates when the water level is low and when it is time to change the filter. Refer to the Quick Start Guide for specific LED light patterns and their meanings.

Maintenance and Cleaning
Regular cleaning and filter replacement are essential for maintaining the fountain's performance and ensuring clean water for your pet. The Outlast Fountain is designed for easy maintenance.
Cleaning the Fountain

- Dishwasher Safe: All plastic components of the fountain (excluding the motor unit, USB cable, and wall adapter) are top-rack dishwasher safe.
- Hand Washing: For hand washing, use warm, soapy water and a soft brush or sponge to clean all parts thoroughly. Rinse well to remove any soap residue.
- Motor Unit: Wipe the exterior of the motor unit with a damp cloth. Do not submerge the motor unit in water.
- Reassembly: Reassemble the fountain once all parts are clean and dry, following the setup instructions in reverse.

Filter Replacement
The Ion-X filter helps keep the water clean and fresh by removing bad tastes and odors, and preventing mineral build-up. Replace the filter every 2-4 weeks, or when the LED indicator signals a filter change.
- Remove Old Filter: Unplug the fountain and remove the old filter from its compartment. Discard the used filter.
- Rinse New Filter: Rinse the new PetSafe Ion-X filter (PAC00-17260) under cold running water for 30 seconds to remove any loose carbon dust.
