Installation 
The blending system utilizes air pneumatics to perform the re-fill function on the ingredient 
weigh hoppers. 
The manufacturer provides all pneumatic plumbing to a single ¼” standard pipe thread 
fitting.  The blender requires a maximum of 60 PSI of compressed air. 
It is the customer’s responsibility to ensure that the air is CLEAN, DRY & LUBRICATED.  
Any component failures due to airborne contaminants will not be subject to warranty 
consideration. 
The working range of the air pressure is from 40-60 PSI.  PSI lower than 40 may result in 
shutoff valve failure.  PSI greater than 60 may result in damage to the plunger cones in the re-
fill hoppers.  A 5 micron filter is recommended. 
Note:  It is the customer’s responsibility to provide proper air pressure regulation, 
filtration, and lubrication devices.
