How to Replace the Zero Installation Purifier Wire Harness

Step 1. Pre-Disassembly and Safety

• Unplug the Unit. Ensure the power cable is completely disconnected from the wall outlet before beginning.
• Access: Remove the front panel and carefully disconnect the control board.

Step 2. Accessing the Internal Frame

• Top Tank Removal: Lift the top tank off the unit and set it aside in a safe location.
• Screw Extraction: * Locate and remove the primary screw located behind the top tank area. To safely access the bottom screws, slide the unit toward the edge of the table/counter until the screws are accessible from underneath. Keep the unit upright to maintain internal stability. (Unscrew 7 screws total: 4 on the bottom, 2 on the back panel, and 1 on top.)

Step 3. Separating the Shell

• Frame Extraction: Once all screws are removed, gently slide the metal frame out of the plastic housing approximately halfway.
• Disconnecting Leads: Before fully removing the frame, reach inside to disconnect any remaining wires and tubing attached to the front of the housing.

Step 4. Wire Harness Replacement

• Documentation: Take clear photographs of all existing connections. This is a critical step to ensure the new harness matches the original configuration.
• Removal: Remove the old harness by pulling back the plastic protective coverings.
  • Tip: Use pliers to pull the covering or use a fingernail at the tip to slide it back.
• Switch Disconnection: To remove the metal prongs from the black switch, use a spoon or a thin flat-head tool. Insert it at the tip of the prong and push outward to release the tension.

Step 5. Reassembly and Testing

• Integration: Reconnect all wiring and tubing as shown in the photographs from the previous section.
• Closing the Unit: Slide the metal frame back into the plastic shell and reinstall all housing screws. Reattach the top tank.
• Final Connections: Connect the new wire harness leads to the control board and snap the front panel back into place.
• Functional Check: Plug the unit back into a power source and verify that the unit is operational.
