Power Source
Determine your power source, either 115 VAC or 12 VDC. Power connects are on the
side of the control panel.
If using Water Level Meter Equipment, connect a drawdown c
able to the ‘AUX INPUT’.
Selecting an Air Source
Air consumption depends on the volume of tubing and the size of deployed Bladder Pump.
Follow the general guidelines and examples below to calculate the air consumption for
specific sampling configurations.

)
= Air Consumption per cycle (in³/cm

)
CAUTION
The BP Controller requires dry, moisture free air.
Disregarding this caution can increase the likelihood of
unnecessary maintenance.
