Once  you  have  connected  the  compressed  air  to  the  APEX  2Q  (via  a  filter  between  tank  and  an 

included mass flow controller), all you need to do is (1) connect the mass flow controller to the COM 

port on the back of the SP2-D, and (2) connect the APEX 2Q to the inlet of the SP2 using a plumbing 

“T

ee

” 

(Figure 2) and then you will be up and running.

While you are setting up the system, you should have two reference documents available and close 

by  for  reference:    1)  The  SP2  Operators  Manual  (included  with  your  SP2),  and  2)  the  APEX  2Q 

Operation and Installation Guide (included with your APEX 2Q).
