WARNINGS
•
Fill the condensate drain syphon (2) to a sufficient level and route the condensate drain hose correctly. Envisage suitable
condensate treatment systems.
•
The safety valve drain must be connected to a suitable disposal system. The manufacturer is not responsible for
possible flooding caused by intervention of the safety valve.
•
Systems charged with anti-freeze require the compulsory use of water shut-off devices.
•
The selection and installation of the system components is the task of the installer, who must observe all current
legislation and professional technical practices.
•
The expansion vessel of the heating circuit must ensure total absorption of the fluid expansion in the system.
b
WARNINGS
•
If the DHW is produced by the storage tank pump located upline of the hydraulic separator, use boiler pump 2 as the
primary pump (without the mix valve).
This enables management of two above pumps, to avoid increases in the temperature of the heating circuit.
