the heat pump can be equipped with duct connections, both at the air inlet and at the air outlet. The air inlet and the air outlet
are located at the top of the heat pump. The ducts should be used with thermal an acoustic insulation.
The duct connections are ø160 mm. To ensure sufficient air flow the following rules should be observed: The total duct
length (suction and pressure ducts) should not exceed 7 m with 160 mm ducts Minimum airflow 200 m
