Basic Operation
10.After the volume for A or B is entered, the ProMix 2KE controller calculates the new pump factor and shows it on Calibration 1 (Screen 22) and Calibra- tion 2 (Screen 23).
11.Before you begin production, clear the system of solvent and prime it with material.
a.Go to Mix mode.
b.Trigger the gun into a grounded metal pail until mixed material flows from the gun nozzle.
If the fluid flow rate is too low: increase air pres- sure to component A and B fluid supplies or increase the regulated fluid pressure of mixed material.
If the fluid flow rate is too high: reduce the air pressure to component A and B fluid supplies, close the dose valves further, or decrease the reg- ulated fluid pressure of mixed material.
4.Turn on atomizing air to the gun. Check the spray pattern as instructed in your spray gun manual.

Purging
NOTE: See Run Mode Details, pages
There are 2 purging procedures in this manual:
•Purging Mixed Material
•Purging Fluid Supply System
Use the criteria listed for each procedure to determine which procedure to use.
