Setup and Installation
Follow these steps to properly install your new LG LT1000P2 water filter:
- Locate the Filter Compartment: The water filter compartment is typically located inside the fresh food section of your LG refrigerator, usually in the upper right corner. Refer to your refrigerator's specific model manual if you cannot locate it.
- Prepare for Replacement: Place a towel or small container underneath the filter housing to catch any residual water that may drip during removal.
- Remove the Old Filter: Twist the old filter counter-clockwise until it releases from the housing. Pull it straight out.
- Prepare the New Filter: Remove the protective cap from the new LG LT1000P2 filter.
- Install the New Filter: Insert the new filter into the housing, aligning the filter with the slot. Push it firmly into place and then twist it clockwise until it locks securely. You should feel it click into position.
- Flush the System: After installation, dispense approximately 2.5 gallons (about 5 minutes) of water through the refrigerator dispenser to flush out any air and carbon fines from the system. This ensures optimal filter performance and clear water.
- Reset the Filter Indicator: Most LG refrigerators have a filter indicator light. To reset it, press and hold the "Filter" or "Water Filter" button on your refrigerator's dispenser panel for 3-5 seconds until the light turns off.
