Operation
All systems include Low/Empty Sensors:
• The air will shut off to prevent the Pump from
cavitation. If the Light Tower kit is installed, a solid
red light indicates that the pail is empty and ready
to change.
• In a tandem system, a flashing red light means that
both drums are empty and the system has
shutdown.

2. Push in the Air Motor Slider Valve (CM) to stop the
Pump.
3. Set Ram Director Valve (CC) to UP and raise the
