Purge Valve
Action:
- If the initial N2 Sensor Test fails, the unit will continue to retest. Wait for 10 minutes.
- Press the Start Purge button again to clear the error code.
- If the Er 1 comes back on the display within ten seconds, check the DIP switch configuration to ensure the elevation setting is correct for your sea level.
- Check to ensure the sensor cable is plugged in correctly.
- Check to ensure the INS-PV is not currently connected to a fire sprinkler system that is already above ambient conditions. Isolate the INS-PV unit using the ball valve. Wait 2 hours and return to press the Start Purge button.
- Contact Potter technical support if error code returns.
