Procedure  
Open ratio check valve (2) and shut off handle (E)  
and take ratio samples.  
Procedure  
1. Close the dual shutoff handle (E), sample valve (2),  
and solvent valve (C).  
7. Close the dual shutoff handle (E) when you have  
enough material. Compare amounts in each con-  
tainer; amounts should correspond to desired ratio.  
2. Set proportioner to 50% of spray pressure.  
NOTE: If you know the mix ratio is by weight, weigh  
tared containers for a more accurate measure. The  
weight ratio will be different than the volume ratio  
unless both fluids have the same specific gravity.  
3. Place waster containers under the hardener and  
resin outlets. Open the dual shutoff handle (E). The  
hardener pressure will drop.  
4. First time use:  
8. Close the resin valve (2). This valve can be left in  
place for future ratio checks.  
a. Open the resin sample valve (2) until you have a  
typical flow or cycle rate.  
9. Flush the hardener outlet tube with solvent. See mix  
manifold manual for instructions.  
b. Adjust the hardener restrictor stem in clockwise  
until the fluid pressure gauges are balanced.  
10. Remove the ratio check plug (4) and o-ring (5) and  
save for future ratio checks.  
c. Close the dual shutoff handle (E).  
NOTICE  
5. Use after the hardener restrictor stem is pre-set:  
To prevent damage to the inlet swivel fittings, use a  
wrench on the front of the mix manifold.  
a. Open the resin sample valve (2) until the fluid  
pressure gauges are balanced.  
11. Reinstall fitting, static mixer, and hose.  
b. Close the dual shutoff handle (E).  
NOTE: The hardener restrictor adjustment should  
now be set correctly for spraying mixed material and  
taking ratio checks. No further adjustments are  
required.  
6. Hold graduated or tared containers under the resin  
outlet fitting (3) and under the hardener outlet tube.
