4. Operating Instructions
Once installed, the Samsung HAF-DIN/EXP bypass plug cap allows your refrigerator's water dispenser and ice maker to function normally without a water filter. Water will flow directly from your home's water supply to the dispenser and ice maker, bypassing the filter housing. This ensures continuous access to water and ice even when a filter is not present or needs replacement.
