For 6LC, V6LC, 12LC and V12LC units 12.5 9.13 only, if equipped with recirculation module, the internal defrost damper opens recirculation opening.
The unit functions are controlled by integrated controls in the unit WARNING which may include Exhaust Only Defrost or Recirculation Defrost (via the recirculation module - 6LC, V6LC, 12LC and V12LC units Disconnect power before maintaining unit. only). In cold temperatures, defrost cycles will remove frost from the heat recovery core to maintain good operation.
