General Observations
Cooling The operational temperature of this unit is between 16°C and 30°C
The interior fan will always continue rotating even if the desired temperature has been
reached and the condenser unit has stopped.
Heating The unit is designed to provide heat in winter by extracting heat from the external air. In
extremes of outside temperature this potential may be reduced.
Expansion/
Contraction
During Heating or Cooling, some plastic pieces could expand or contract due to the
variation on temperature. This phenomenon is normal and disappears after some
instants.
