RECOMMENDATIONS FOR THE HYDRAULIC INSTALLATION
• Thoroughly rinse the system before connecting the boiler
• Water treatment is recommended to prevent corrosion and the formation of scale in the boiler and piping.
• If the boiler is to be installed in an existing system, ACV recommends using a cleaning agent in the
systems.
• After connecting the hydraulic circuit, check the absence of leaks.

without draining the whole system.
