Machine features Range The LYRA 2T heat pump units are designed for applications using radiant panel heating systems or low temperature applications such as suitably dimensioned fan-coil, thermal ventilation and AHUs for delivery temperatures of 60°C. All versions are equipped with extremely silent EC axial fans and Twin Rotary inverter compressors that allow the complete power management of each single component.
Machine identification The equipment is identified by: • Packing plate (A). It provides the equipment identification data. • Nameplate (B). Applied to the machine, it shows the technical and performance data of the equipment. In case of loss or deterioration, request a duplicate to the Technical Customer Service. DANGER! The tampering with, removal and deterioration of the identification plates make it difficult to install, maintain the system and request spare parts.
Machine description 4.3.1 Outdoor unit • The structure is made of thick galvanised sheet metal painted with epoxy powders. The panels of the compressor compartment are totally soundproofed by means of a sheet with high soundproofing characteristics. The compressor compartment is accessible via removable front panels.
