When mounting an induction heating coil keep the following steps and tips in mind:
1. Turn o
ff
cooling water.
2. Turn o
ff
the main switch.
3. Place a bucket under the inductor to capture leaking cooling water.
4. Loosen
the nuts (6) on the coax face plates (2) in order to release the coil clamps (5).
5. Pull the inductor (1) towards the top and remove.
6. Clean both contact surfaces (3) with a Scotch-Brite
TM
pad.
7. Check both O-rings (4) for damage and replace them if necessary.
8. Check both contact surfaces (3) for damage.
9. Insert the new coil. Make sure the coil and the coaxial transformers have a tight fit.
Use the following torques when tightening the nuts:
Please also be aware of the following:
•
Over-tightening can lead to thread stripping on the nuts (6).
•
Under-tightening can lead to:
•
Arcing between the coil and coax contact surfaces (3), which can lead to
surface pitting.
•
Current running through the stud to the clamp, which can melt the stud.
Caution! Be sure to use only brass nuts and washers!
