ATTENTION:
For a correct startup of the heating appliance an adequate circu-
lation of the cooling medium must be ensured before switching on.
The heating appliance is preferably to be equipped with Valeo circulation
pumps.
NOTE:
For information about these circulating pumps and
their installation, see http://www.valeo-thermal-
bus.com/eu_en/Products/Pumps
The water flow rate through the heat exchanger of the Thermo AC 070
must be more than 1,500 litres/hour. The system must be completely
bled.
The triggering/activation of the circulation pump is not carried out by the
heating appliance. For this reason the coolant demand must be provi-
ded for at the vehicle.
