Hot Water System - Webasto DUAL TOP RHA 100 Installation Manual

Hot water system

The Dual Top complies with all applicable standards for this type of prod-
uct. When installing 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).
NOTE
During and after installation of the water system, it must be ensured that
no dirt can enter into the water circuit.
To avoid leaks, 10 mm standard hose connector should be used to connect
water lines or hoses to the heater (e.g. John Guest/ASP). The coolant pipes
on the Dual Top are specially equipped with grooves which enable proper
fastening and easy removal of the hose connectors if necessary.
• 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).
