Operating Instructions
Once installed and primed, the pump is ready for operation.
- Initial Start-up: Turn on the power supply to the pump. The pump should start and begin to build pressure.
- Automatic Operation: The integrated pressure switch is pre-set to turn the pump on at 30 PSI and off at 50 PSI, maintaining consistent water pressure.
- Monitoring: Observe the pressure gauge (if installed) to ensure the pump is operating within the expected pressure range.
- Continuous Operation: The pump is designed for intermittent use as demand requires. Avoid prolonged dry running.
