Important notice !

These hydraulic diagrams are schematic representations and are for assistance only. They do not relieve of the obligation to ca

rry out appropriate planning! They do not include all necessary shut-off valves, ventilator 

fittings or safety devices. These must be incorporated in accordance with the standards and regulations applicable to the respe

ctive installation. All country-specific standards, laws and regulations must be observed! The 

tubes have to be dimensioned according to the nominal volume flow of the heat pump resp. the free pressing of the integrated ci
