Pumps and Sensors

• If using feed pumps, do not allow feed pressure to exceed 25% of spray pressure.

For accurate ratios, pump lowers must be same size.

If installing 234024 or 234025, the pump size has not been set in the software. To set pump A and B size and A and B sensor calibration factors, you need Xtreme Mix Data Download software, part no. 246322 for proportioners located in a non-hazardous area, or part no. 246397 for proportioners located in a hazard- ous area.

Calibration values are on pump A and B sen- sors.
