SYSTEM emergency operation
If the heat pump is not working correctly or the compressor
has shut down, emergency operation can be activated.
Emergency operation involves heating the water using the
electric heaters available on the system (outlet, storage

the proportion recommended by the manufacturer.
It is recommended to use non-toxic food grade
antifreeze, compliant with the standards in force in the
countries where the unit is used, if domestic hot water
production is also featured.
If the mains switch is turned to "off" for more than four
hours, after turning it on and before reactivating the unit,
leave the power on but the unit deactivated for at least
two hours to preheat the oil in the compressor sump.
