Function Description:

The Sub-Zero 4204490 Water Filter is a crucial component for maintaining water quality in Sub-Zero Built-In (BI), PRO48 Series, and New Generation Integrated units. Its primary function is to filter impurities from the water supply, providing clean water for ice production and dispensing. The document emphasizes the importance of using only authentic Sub-Zero branded cartridges to prevent problems with the unit and avoid voiding the warranty.

Important Technical Specifications:

While specific technical specifications like micron rating or flow rate are not detailed in this document, the filter is designed to be compatible with specific Sub-Zero models: Built-In (BI), PRO48 Series, and New Generation Integrated units. The installation process involves a quarter-turn rotation for both removal and insertion, indicating a standardized fitting mechanism. The filter is expected to remove impurities effectively, as suggested by the post-installation recommendation to discard initial ice and dispensed water to clear the system.

Usage Features:

Accessing the Water Filter:

• Built-In (BI) or PRO48 Series units: Access is gained by pulling out the bottom edge of the grille assembly and tilting the grille frame forward.

Removing the Water Filter:

• The cartridge is removed by rotating it counterclockwise one-quarter turn and then pulling it out.
• It is normal for a small amount of water to spill during removal, indicating the presence of water within the cartridge.

Replacing the Water Filter:

• Before installation, the new filter cartridge must be removed from its packaging, and the plastic cap should be carefully removed.
• The new filter is inserted into the manifold and turned clockwise until it is securely seated.

Post-Installation Procedures:

• After installing a new filter, it is recommended to discard the first full bucket of ice produced to help clean the water system and clear air from the line. A 24-hour waiting period is suggested before discarding this first bucket of ice.
• For dispenser models, while the water line is typically purged before connecting to the unit, the first several glasses of water should be discarded after replacing the filter to ensure optimal water quality.
