Normal noise during operation
During normal operation, the equipment may make particular noise
linked to settling, expansion of the materials or refrigerant flow. This
type of noise should not be considered a fault:
— ticking due to expansion or shrinking of materials upon tem-
perature changes
— hiss due to refrigerant cycle inversion when changing operat-
ing mode and toggling between Cooling and Heating or during
defrost
— swish similar to water flowing due to the refrigerant gas flowing
in the unit
