  • Designed to maximize sensible and latent cooling performance at design conditions.
  • System can operate from 35 F to 125 F without any additional controls.
  • R-410A Refrigerant
  • Non-chlorine, ozone friendly, R-410A.
  • Unit is factory pre-charged with refrigerant. See Specifications Table.
  • Compressor
  • Resiliently mounted on rubber grommets for quiet operation.
  • Scroll compressors for high performance, reliability and quiet operation.
  • Compressor Crankcase Heater
  • Protects against refrigerant migration that can occur during low ambient operation.
  • High pressure Switch
  • Protects the compressor from overload conditions such as dirty condenser coils, blocked refrigerant flow, or loss of outdoor fan operation.
  • Reversing Valve
  • 4-way interchange reversing valve effects a rapid change in direction of refrigerant flow resulting in quick changeover from cooling to heating and vice versa.
  • Defrost Control
  • Provides a defrost cycle, if needed, every 30 or 60 or 90 minutes (adjustable) of compressor on time at outdoor coil temperature below 35 F. Temperature switch mounted on outdoor coil liquid line terminates defrost cycle.
