Automatic Air Purge Operation (Start-Up)
All systems with this controller are equipped with our auto-air purge function, it is factory set for
five (5) minutes. When the system is started, the controller will operate a timer for five (5)
minutes. The controller should be set at the minimum temperature, and the scrolling text will read
“Auto Air Purge.” OP4 and Run will illuminate on the controller. The system should automatically be
purged of air at the end of the five (5) minute timer. If pressure gauges are still erratic or air
appears to still be present, refer to Section 5.6 for restarting the automatic air purge timer.

drain.)
