4. Installation Instructions
Follow these steps to install or replace your Brio Quick-Change Water Cooler Filter Cartridge:
- Turn Off Water Supply: Locate the water supply valve to your Brio water cooler and turn it off. This prevents water leakage during filter replacement.
- Depressurize System: Dispense water from the cold water faucet until the flow stops. This releases pressure from the system.
- Remove Old Filter: Open the filter compartment door on your water cooler. Grip the old filter cartridge firmly and twist it counter-clockwise approximately a quarter turn until it disengages. Pull the filter straight down to remove it.
- Prepare New Filter: Remove the new Brio Stage-2 Pre Carbon filter from its packaging. Ensure the O-rings are properly seated on the filter head.
- Install New Filter: Align the top of the new filter cartridge with the filter head in the water cooler. Push the filter straight up into the head and then twist it clockwise approximately a quarter turn until it locks securely into place. You may feel a slight click.
- Restore Water Supply: Slowly turn the water supply valve back on.
- Flush Filter: Dispense approximately 2-3 gallons of water through the cold water faucet to flush the new filter. This removes any carbon fines and air from the system. The water may appear cloudy initially; this is normal and will clear up.
- Check for Leaks: Inspect the filter connection points for any signs of leaks. If leaks are present, ensure the filter is properly seated and twisted securely.

5. Maintenance
Regular filter replacement is crucial for maintaining optimal water quality and system performance.
Filter Replacement Frequency:
It is recommended to replace the Brio Stage-2 Pre Carbon filter cartridge every 3 to 6 months. Actual replacement frequency may vary depending on your local water quality and usage volume. A decrease in water flow or a noticeable change in water taste or odor indicates that the filter may need to be replaced sooner.
