WaRNING

to prevent serious injury and 

death from improper installation:

ONLY a qualified engineer with 
appropriate certifications may attempt 
designing a new compressor to ensure 
that all required safety and control 
elements are in place and will work 
together properly and safely.  This 
compressor pump is intended ONLY 
as a replacement for a similarly rated 
pump on an existing compressor that 
includes all other needed components.  
Constructing a new compressor using 
this pump is not covered by the manual.
