Lennox 16F18 Low Ambient Kit

The Lennox 16F18 Low Ambient Kit functions as an essential part that enhances the performance of ELS and EL series HVAC system units. The kit operates through a pressure transducer system that tracks liquid line pressure during temperature drops and falling pressure until the ICM controller adjusts condenser fan speed instead of complete shutdown. The variable speed operation maintains the required head pressure to keep the system operating properly without any disruptions. This part delivers three main advantages which include better reliability under cold conditions and better energy efficiency through optimized fan operation and protection against system freeze-up.
