3. Setup and Installation

Proper installation is crucial for the optimal performance and longevity of your water filter system. Please read all instructions carefully before proceeding.

3.1 Pre-Installation Checklist:

• Ensure you have all parts listed in Section 2.
• Gather necessary tools: adjustable wrench, drill (if needed for faucet hole), screwdriver, bucket, towels.
• Locate a suitable mounting area under your sink, ensuring enough space for filter changes.
• Turn off the cold water supply to your sink before starting.

3.2 Installation Steps:

1. Install Faucet: If a dedicated faucet hole is not present, drill one according to the faucet's specifications. Secure the faucet (C) to the sink using the faucet gasket (H), decorative spacer (I), decorative spacer gasket (J), and mounting nut. Connect the faucet spout (K) if it's separate.
2. Connect Water Supply Line Adapter: Turn off the cold water supply. Disconnect the existing cold water line from the shut-off valve. Install the water supply line adapter (E) onto the cold water shut-off valve. Caution: The plastic fitting on the adapter can be easily cross-threaded. Ensure it is perfectly aligned and hand-tighten initially. Only use a wrench for the final snugging. Over-tightening can damage the fitting and cause leaks.
3. Connect Tubing: Connect one end of the coiled tubing (D) to the water supply line adapter (E) and the other end to the filter head assembly (B). Connect the tubing from the faucet (C) to the filter head assembly (B). Ensure all quick-connect fittings are fully inserted and secure.
4. Mount Filter Head Assembly: Choose a secure location under the sink to mount the filter head assembly (B) using the provided mounting screws (L). Ensure there is adequate clearance below for filter replacement.
5. Install Filter: Insert the filter cartridge (A) into the filter head assembly (B) by aligning the tabs and twisting until it locks into place.
6. Check for Leaks: Slowly turn on the cold water supply. Check all connections for leaks. If leaks occur, tighten connections carefully. If a leak persists from a quick-connect fitting, ensure the tubing is fully inserted and the connection is secure.
7. Flush System: Open the dedicated filtered water faucet and let water run for 5-10 minutes to flush out any carbon fines and air from the system. The water may appear cloudy initially; this is normal.

Important Considerations:

• If your existing cold water line uses a rigid pipe, you may need to replace it with a flexible supply line to accommodate the water supply line adapter and ensure proper fit.
• Familiarize yourself with quick-connect fittings before working under the sink to ensure proper connection and disconnection.

4. Operating Instructions

Once installed and flushed, your 3M water filter system is ready for use.

• To dispense filtered water, simply open the dedicated filtered water faucet.
• The system provides a strong flow rate for quick access to filtered water.
• For best results, use the filtered water for drinking, cooking, and preparing beverages.

5. Maintenance and Filter Replacement

Regular filter replacement is essential to maintain the performance of your 3M water filter system and ensure continuous access to clean water.

5.1 Filter Replacement Schedule:

• The replacement filter model is 4US-MAXS-F01H.
• Replace the filter cartridge every 6 months or sooner if you notice a significant drop in water flow or taste/odor issues.
• Use the included filter change indicator (M) to mark the installation date and remind you when to replace the filter.

5.2 Quick-Change Filter Replacement Steps:

1. No Water Shut-off Required: The quick-change design allows for filter replacement without turning off the main water supply.
2. Remove Old Filter: Grasp the old filter cartridge (A) and twist it counter-clockwise approximately a quarter turn until it releases from the filter head assembly (B). Pull the filter straight down to remove it. A small amount of water may drip out; this is normal.
3. Install New Filter: Remove the protective cap from the new 4US-MAXS-F01H replacement filter. Align the tabs on the new filter with the slots in the filter head assembly (B). Push the filter up and twist clockwise approximately a quarter turn until it locks securely into place.
4. Flush New Filter: Open the dedicated filtered water faucet and let water run for 5-10 minutes to flush out any air and carbon fines from the new filter.
5. Reset Indicator: Update your filter change indicator (M) with the new installation date.

Important Note Regarding Replacement Filters: Some users have reported difficulty in sourcing the 4US-MAXS-F01H replacement filters, with claims that 3M may no longer produce them.
