Product Overview
Lennox 618662-04, Low Ambient Kit - Variable for use with TSA 180, 240 Series Units
During low ambient conditions, the liquid line pressure will fall. If the pressure gets too low, the system will not have enough pressure drop across it to operate properly. To maintain the head pressure, the low ambient kit, instead of shutting down the condenser fan, slows down the condenser fan until the head pressure rises to the set point.This kit is designed for use in ambient temperatures no lower than 0°F (−17.8°C) unless otherwise noted in the Engineering Handbook.
