Alternate VaporTEK-3 Controller Board Mounting
This procedure is required when installing the VaporTEK-3 Controller board in the dispenser electronics
compartment as a standalone component.
1. Prior to mounting the board onto a sheet metal surface of the electronics compartment, paint the bottom
surface areas of the board’s motion controller and rectifier chips (Figure 12) with a thin film of thermal transfer
paste (NTE303 or equivalent).
Figure 12. Apply Thermal Transfer Paste To These Component Surfaces
1. Fasten the VaporTEK-3 Controller board to the mounting surface with three M3-0.5 X12 long screws, and
three M3-0.5 tooth washer hex nuts, (see Item 1, Figure 3). Torque each screw to a nominal 0.60 N-m (min.
0.50 N-m / max. 1.00 N-m).
