To insulate the water piping
The piping in the complete water circuit must be insulated to prevent
condensation during cooling operation and reduction of the heating
and cooling capacity.
If the temperature is higher than 30°C and the humidity is higher
than RH 80%, the thickness of the sealing materials should be at
least 20 mm to prevent condensation on the surface of the sealing.
