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
temperature changes
—
hiss due to refrigerant cycle inversion when changing op-
erating mode and toggling between Cooling and Heating
or during defrost
— swish similar to water flowing due to the refrigerant gas
flowing in the unit
