Install the snubber resistors

Notice

POSSIBLE DAMAGE TO EQUIPMENT

Do not apply too much thermal grease to the components on the power PCB. Too much grease can cause damage to the power PCB and to the plasma power supply.

Apply only a very thin layer of thermal grease as shown in this procedure. Do not apply all of the 1/8 ounce of grease that is supplied in the kit.

Clean the area where the snubber resistors were mounted.

Use isopropyl alcohol to remove the old thermal grease from the heatsink.
Apply a 0.0762 mm (0.003 inch) layer of thermal grease, about the thickness of a sheet of paper, evenly on the new snubber resistor mounting surface.
Mount the snubber resistors to the heatsink.

Step-torque the mounting screws to 2.3 N∙m (20 lbf·in).
Complete the following procedures:
1. Install the power PCB.
2. Install the component barrier.
3. Install the plasma power supply cover and handle.
4. Reconnect the gas supply.
5. Reconnect the power cord.
