6. Remove the return springs and set them aside. Turn the Base Assembly over and remove the (4) screws that secure the coil assembly
to the Baseplate.
(Figure 3D)
7. Install new coil assembly in position using (4) screws (tighten to 30 lb-inches). Replace the Return Springs by placing them over the
spring support pins located within the coil magnet core assembly making sure the return springs are properly seated and not interfering
with any of the control wiring.
(Figure 3C).
8. Carefully replace the Main Housing assembly loosely, making sure it is orientated correctly. Carefully locate the magnetic armature
poles (the poles sticking down from the upper housing assembly) into the coil magnet core assembly. Note: This is a blind operation with
careful side to side motion. Pay close attention to alignment of the locating bosses positioned at the bottom of the main housing
assembly. To reattach the Main Housing assembly insert the main housing locating bosses into the two mounting plate holes while
compressing the return springs with the Main Housing. Start the four Main Housing screws into the mounting plate. Tighten the mounting
screws equally in a diagonal pattern approximately two turns at a time until tightened to 40 lb-inches in the same diagonal pattern.
9. Reinstall the Control-Pak (Figures 4). First, rotate the Retainer upwards. Next, insert the lower tab into the recess on the side of the
contactor base. With proper installation, the Control-Pak Actuator will fit into the hole in the center of the brass stud - which can be viewed
through the slot in the side of the contactor housing. Using a thin screw driver or other thin rod, push the Control-Pak Actuator up or down
as necessary to insert it into the brass stud mentioned. Rotate the Retainer to its original position, which will slide over the upper tab on
the Control-Pak.
10. Reinstall the cover and secure it with the original mounting hardware. Tighten the four screws in a diagonal pattern to 5 lb-inches.
(Figure 3A).
11. Reattach the coil wire leads to the Control-Pak (tighten to 7 lb-inches).
12. Reinstall the device and reconnect any auxiliary control wires. Reconnect the line and load conductors and tighten the main terminal
hardware and bolts to 180 lb-inches.
