MicroVission Retrofit Instructions • 35391MVRF

WARNING

When  handling  microcontroller,  use  additional 
personnel  or  lifting  device  as  required.  Failure  to 
comply may result in serious injury and/or damage to 

equipment.

  Step 4

. Mount the MicroVission bracket to the compressor frame with four (4) 3/4” bolts and hardware provided. If the 

compressor base is filled with concrete the bracket can be welded to the compressor frame.  Follow standard 
practices for welding and fabrication procedures.

Step  5

.  Mount  the  Block  &  Bleed  bracket  with  valves  and  hardware  from  KT1133A9(A10)  and  install  the  pressure 

transducers as shown as in Figure 9 and Figure 10.  

 

 

Mount and install 1/4” ASTM A179 steel tubing (provided by others) between pressure transducers, suction, 
discharge, and oil manifold connections.

 

 

Verify correct transducer pressure ranges:* 

Suction

Discharge

Oil Manifold

0-200 psia 0-414.5 psia

0-200 psia

*0-414.5 psia intermediate on integral 2-stage compressors

NOTE

If excesive vibration occurs, further support from the 

controller bracket to the base may be required
