618662-02, Low Ambient Kit, 16X32

Lennox 618662-02, Low Ambient Kit - Variable for use with TSA 120A 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. Includes: (1) - ICM Controller ICM Controller harness (1) - Pressure transducer (1) - Fan power harness (1) - Valve depressor w/ two cores (1) - Two-pole relay Wiring diagram sticker Wire ties / Self-tapping screws
