3. Maintenance: Filter Replacement
Regular filter replacement is crucial for maintaining the performance and water quality of your SimPure Y9 Series system. The twist-in filter system allows for quick and tool-free replacement.
Filter Replacement Steps:
- Prepare for Replacement: Ensure the water filter system is unplugged from the power outlet. Place a towel or small container beneath the filter area to catch any residual water.
- Remove Water Tank: Carefully lift and remove the external water tank from the system.
- Access Filters: Open the filter compartment cover. The filters (PPC, T33, RO) will be visible.
- Remove Old Filters: For each filter, twist it counter-clockwise to unlock it from its housing. Gently pull the filter downwards and then out. Dispose of the old filters responsibly.
- Install New Filters: Remove the packaging from the new filters. Align each new filter with its corresponding slot (PPC, T33, RO are typically labeled on the system and filters). Push the filter upwards and twist clockwise until it locks securely into place.
- Replace Water Tank: Carefully place the external water tank back onto the system, ensuring it is properly seated.
- Flush the System: Plug the system back into the power outlet. Fill the water tank with tap water. Dispense water from the system several times (typically 3-5 full tanks) to flush out any air and carbon fines from the new filters. Discard the flushed water.
- Reset Filter Indicators: After flushing, locate the reset button on your system's control panel. Press and hold the reset button for approximately 3 seconds until the filter indicator lights reset, confirming the new filters are recognized.
Your SimPure Y9 Series system is now ready for use with the new filters.
