General Operations Manual


Program Scope

This certification program applies to models of 50 and 60 Hz VRF multi-split systems and VRF heat recovery multi-split systems that meet the following criteria:
  • Include multi-split, matched system air-conditioners and heat pumps irrespective of their type of electric power source, or secondary fluid (e.g. air-to-air or water-to-air).
  • Use distributed refrigerant technology with cooling and heating capacities for Outdoor Units and Water Source Units from 12,000 Btu/h [3508 W] to 760,000 Btu/h [222,734 W] and indoor units from 5,000 Btu/h [1,462 W] to 144,000 Btu/h [42,202 W]. Each indoor unit is designed to condition a single zone.
  • Consisting of the following matched components: a) an Outdoor Unit with single or multiple compressors or variable capacity compressor; b) indoor units that have a coil, air movement device intended for single zone air distribution, and a temperature sensing control; and c) a zone temperature control device.
