You may need to remove the Sensor PCB cable from the Control PCB to
allow access to the connector of some zones.

Installing a New Proportional Valve
1. Before inserting the new valve, check the position of the o-ring on the valve.
2. If the o-ring is positioned at top of groove, use a solder aid or non-metal pick to roll the o-
ring down to the bottom of the groove. The o-ring must not be twisted.
3. Insert the new valve into its position in the enclosure. The wires coming out of the coil
should face the Control PCB (See Figure 8-21).
4. Assemble the spring or Belleville washer and hex socket head screw, ensuring that the
concave side of the washer is facing away from the head of the screw.
5. Start the screw with the spring washer in the hole next to the valve.
6. Press down on the center of the valve and finish tightening the screw.
7. Insert and tighten the second screw and washer, if applicable.
8. Plug all cables back into their corresponding connectors on the Control PCB.

remove the old valve and install a new one.

16 in.-lb, using ABB Tool TL1000/TL1002. Ensure that the flame-proof or explosion-proof
surfaces of the cover or the body of the Control Assembly are not damaged.
