INSTALLATION & USE
Wire Connection Procedure

- Hold wire ends parallel and aligned, then insert together into the Fleck 40422 wire nut

- Gently tug each wire to confirm mechanical connection, then tuck completed joint into control valve junction box
COMPATIBILITY
System Fitment
The Fleck 40422 wire nut is compatible with all Fleck control valve models including the 5600, 5600SXT, 7000, 9000, and 9100SXT series. This is a direct OEM replacement component for electrical connections within the valve head assembly and transformer wiring junctions. Suitable for use in residential water softener and filter system control valve installations where secure electrical terminations are required.
🔧 Pro Tip: Before connecting wires with the 40422 wire nut, twist the stripped wire ends together clockwise by hand first. This pre-twist creates a stronger mechanical connection and ensures the wire nut threads properly over the joint rather than just pushing wires together.
