Common Questions & Instructions
What speed should I run this pump on for daily filtration?
For optimal energy savings, we calculate your pool's required 'turnover rate'. Typically, running the pump at a low speed (1700-2000 RPM) for 12 hours moves more water for less money than running a high speed for 4 hours.
Will this work with my pool heater?
Yes, but gas heaters and heat pumps require a minimum flow rate to activate their pressure switches. You will need to program one of the daily schedules to run at a higher RPM (e.g., 2800 RPM) during the times you wish to heat the pool.
Is changing from 115V to 230V difficult?
The WhisperFlo VST automatically detects and adapts to 115V or 230V power. We highly recommend professional installation to ensure electrical safety and validation of your Pentair warranty.
