Connection of the heat pump to the same pipeline whit the kitchen vent, the ventilation system of smaller
apartments is not allowed.
During operation of the heat pump condensate forms in the aggregate. The condensate should be drained to the sewage system
via flexible tube Ø16mm on the rear side of the heat pump. The quantity of condensate depends on air temperature and humidity
or air.

The calculations of the pressure values are informative. More accurate calculations of airflows require more detailed characteristics
of individual elements or information from the developer. After the installation we recommend measurements of the airflow in
the pipeline system. Values of total static pressure drop are calculated by adding up pressure drops of each individual element,
installed in the air pipeline system. Recommended nominal operation is at the sum total of ca. 100 Pa. In case of airflow decrease
COP drops.

Values of total static pressure drop are calculated by adding up pressure drops of each individual element, installed in the air
pipeline system. Values of pressure drops of each individual element (diameter 150 mm) are presented in the following table.
