Test for Control Valve
Problem #2
Does the control valve get a
signal?
Remove Yellow tube from
Auger Control Valve CV-2.
Pull Trigger, air should come
out of yellow tube.
If no then the problem is in the Yellow tube
manifold. Check for leaks, blockage or kinks.
If yes this will indicate a problem with the
Control Valve CV-2, go to next test.
Test for Control Valve
Problem #3
Is there supply air to the control
valve?
Close System Supply Valve and
wait a few seconds.
Remove the 3/8” black tube
from the lubricator inlet.
Open System Supply Valve.
Air should come out black tube.
If no, then the problem is in the Check Valve
CK1, ICE RATE regulator REG5, or the air
supply to it.
If answer is Yes to all three tests then Replace
