2.2 Installation when retrofitting from pressure switches
The mounting position of the MicroVission controller will depend on the type of drive your compressor uses, see Figure
7 for reference.
Step 1 . Shut Off the 120V power to the compressor controls and isolate the compressor by shutting Off all service
valves and lock out per plant procedure. Remove and recover the refrigerant from the compressor so it is at 0 psig.
Step 2 . Disconnect the wiring and remove the existing pressure switches (or Non-Vilter control panel) and all control
tubing.
Step 3 . Position the bottom edge of the MicroVission frame flush with the bottom of compressor base. Mark and drill
four (4) 0.8125” (13/16”) holes, see Figure 8.
