Heat Pump Systems

M-Series Heat Pump Systems

SLZ-KA/SUZ-KA

Overview

Ceiling-recessed cassette (24"x24") ductless heat pump units offer a wide airflow pattern for better air distribution in a less obtrusive style.  Intall SLZ in a hard ceiling (with an access panel for servicing) or in a 2'x2' drop ceiling. Rated capacities range from 8,400 to 15,000 Btu/h.

  • Wide airflow pattern for excellent air distribution
  • 4" ventilation air intake knockout
  • Built-in drain condensate lift mechanism
  • Select from MHK1 (preferred), PAR-21MA, or PAR-FL/FA32 remote controllers
  • Long-life air filter included
  • Automatic fan speed control
  • Limited warranty: five years on parts and defects and seven years on compressors
