OPERATION  
The AROĆSTOP control valve senses an increased volume of air to the  
pump, beyond the preadjusted setting, and shuts off the air supply to  
the pump. The runaway" condition may be caused by any of the followĆ  
ing: 1.)depleted pumping material, 2.)a ruptured line on the outlet of  
the pump, 3.)excessive cavitation in the material supply.  
INSTALLATION  
The AROĆSTOP valve should be installed in a filtered and regulated air  
line as close to the inlet of the pump as possible. Equipment other than  
a lubricator should not be installed between the AROĆSTOP valve and  
the inlet of the pump. Upstream plumbing from the AROĆSTOP valve  
should be 1/2" minimum. A swivel or 1/2" connector & coupler shouldbe  
installed before the AROĆSTOP valve to facilitate easy adjustment.  
Use one AROĆSTOP valve for each pump. See typical installation phoĆ  
to.  
ADJUSTMENT  
THE AROĆSTOP VALVE MUST BE PROPERLY ADJUSTED AND  
TESTED. THE INSTALLATION SHOULD BE TESTED REGULARLY  
AND ADJUSTED WHEN A CHANGE IN OPERATING CONDITIONS  
OCCURS.

siphon tube)from the material supply. If the pump shuts off, the unit  
is set properly.  
2. Supply AROĆSTOP valve with desired inlet operating pressure.  
3. Depress C" reset button on the AROĆSTOP valve to start the  
pump. Open the pump outlet to the desired flow condition.  
4. Turn A" sleeve counterclockwise slowly until the pump stops.  
5. Turn A" sleeve clockwise one turn and tighten B" locking nut  
against body.  
8. If the pump continues to turn, resubmerge the pump (or siphon  
tube)in the material supply. Loosen the B" locking nut and turn the  
A" sleeve counterclockwise approx. one half turn, tighten B" lockĆ  
ing nut, and repeat step (7).  
RESTART:  
9. To restart: Remedy the cause of the shutdown. If the air supply is  
shutĆoff, turn the air back on.  
10. Depress the C" reset button and hold it in approx. 3 seconds.
