2.2 Regulator Startup

Before the startup, check that the Regulator is installed correctly and all hose connections are in place
with the hose clamps tightened.
1. With the pot pressure valve OFF attach the compressed air line to the pot.
2. Verify that the Abrasive Regulator is turned OFF
3. Set the pot air regulator pressure to 40 psi.
4. Fill the pot with at least 500# of abrasive or until full.
5. Turn the pot pressure to ON.
6. With lines from the pot empty turn the regulator ON
The abrasive will initially feed from the pot unevenly until the air in the feed hose is replaced with
abrasive. When the line becomes stable (full of abrasive), there will be no flow unless the abrasive
metering regulator is turned on. For longer delivery lengths, the pot pressure may need to be increased
to a maximum of 80 psi to accommodate for the additional length.
NOTE: If the abrasive flows after turning the regulator OFF do not plug the top of the metering
regulator top vent. The top vent elbow is necessary for venting.

Metering Regulator Flow Rate

The abrasive flow rate coming from the Metering
Regulator can be adjusted by turning the Metering
Control Knob. Turning the knob will change the
size of the hole in the metering aperture. This
abrasive flow rate can be adjusted during cutting.
This adjustment knob is marked in one quarter
graduations starting at 1 and going to 10.
Any over travel in either direction beyond these
markings is normal and will not effect the metering
rate adjustment.
The Abrasive Regulator also uses a gate controlled
by an air cylinder to turn the abrasive flow on and
off.
Abrasive Settings
The Control Knob Setting chart is based on 80HPA
garnet and gives the abrasive flow rates that can be set
by adjusting the knob settings. Actual rates may vary
slightly due to abrasive grit size and the feed pressure
into the regulator acrylic tube.
