Hot water system

The Dual Top complies with all applicable standards for this type of
product. When intalling the Dual Top heater and related components,
make sure to follow all local regulations (e.g. 98/83/EC, DIN 2001-2,
DVGW W 291).
To connect water pipes or hoses to the Dual Top RHA 100 heater, use a
standard 10 mm pipe connector (e.g. John Guest / ASP).
• Place a thermostatic mixing valve if required.
• If no quick connection system is used, secure the lines at all connection
points in a way that they can withstand pressure and are watertight.
• Fasten the hoses in a way that they cannot be damaged (e.g using hose
clips).
