130156 Cartridge: 3/4" Exact Temp System (Prior to 2009)

Disassembly:

1. Use a Phillips screwdriver to unthread the screw (#1) counter-clockwise.
2. Remove the override actuator (#2) by rotating it clockwise until it stops and then gently pull it off. Slide the spring (#3) off.
3. Remove the temperature limit stop (#4) by pulling it off.
4. To avoid damaging the retainer nut (#5), position pliers on the flat edges of the retaining nut (#5) and unthread it counter-clockwise to remove.
5. To remove the cartridge (#6), use pliers on the hexagonal sides (see Image 1) and unthread it counter-clockwise approximately 12 times. Pull the cartridge (#6) out.

Assembly:

1. Insert the cartridge into the valve body (#7) pushing it back as far as it will go. Use pliers on the hexagonal sides of the cartridge (#6) and rotate clockwise until tight.

2. Place the retainer nut (#5) on the valve body (#7) with the flat edges away from the valve body (#7). Position pliers on the flat edges of the retainer nut (#5) and rotate clockwise until tight.

3. Position the temperature limit stop (#4, see Image 2) and push it onto the front of the assembly.

Take special note of the location of the raised lip.

4. Before proceeding, take notice of the tab on the back of the override actuator (#2). The tab will need to be positioned to the right of the raised lip (see Image 2) on the front of the temperature limit stop (#4). To make Step 5 easier, position the screw (#1) inside the override actuator (#2).

5. While holding the spring (#3) in place and with the override actuator (#2) positioned (as explained in Step 4) over the front of the assembly, tighten the screw (#1) clockwise.
