Typical Surface Pressure Boosting Application
The above drawing illustrates how a typical surface mounted pump system should be arranged for a pres-
sure boosting application.
Water Supply
1.
2. Check Valve
3. Ball Valve
4. Pressure Relief Valve: Pressure relief valve must be able to pass full pump flow at 100 PSI.
Risk of bodily injury or property damage.
•
Pumps can develop very high pressure in some situations. Always install a pressure relief valve able
to pass full pump flow at 100 psi.
•
Install the pressure relief valve near the pressure tank and route to a drain capable of full system flow.
5. Pressure Tank. Refer to
6. Pressure Gauge
Pressure Transducer or Sensor: Locate within 5 feet (1.5 m) of pump discharge. Install in a vertical

position.
8. UT3P Drive
9. Power Supply from Circuit Breaker. Single phase, 208/230 VAC +/- 10%.
10. Power to Motor: Three-Phase 230 VAC.
11. Optional Bypass: For system maintenance.
IMPORTANT: If the pump is equipped with a built-in pressure switch, the power wires from the drive must
bypass the pressure switch and connect directly to the motor.
