Important Notes

• Heat pumps must be commissioned by Viessmann Technical Service or a specialist heat pump contractor certified by Viessmann
• A hydraulic connection set must also be ordered to install the appliances.
• If the heat pump is being installed to modernise a heating system, a dirt separator with magnet is essential.
