filter, regulator, and shutoff valve are recommended components
of your in-plant compressed air supply.
You may need to install an accumulator in your air supply system
to enhance blowback effectiveness if your system cannot

1/2” diameter pipe or tubing when making connections.
4-8 Making Electrical Connections
The controller you selected is shipped pre-wired to the hopper
loader. Units are supplied with a power cord with plug wired to the
control unit, ready to plug into an appropriately grounded three-
prong receptacle.
Make sure that the material demand sensor is installed with the
proper amount of clearance, and that it is free of obstructions.
If the installation has the hopper loader wired directly to a power
main, you must install a fused disconnect with lockout to allow
safe operation and maintenance. Make sure all connections are
tight.
