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