10.3 Initial start-up at low outdoor ambient temperature

During initial start-up and when water temperature is low, it is important that the water is heated gradually. Failure to do so may
result in concrete floors cracking due to rapid temperature change. Please contact the responsible cast concrete building
contractor for further details.
To do so, the lowest water flow set temperature can be decreased to a value between 25°C and 35°C by adjusting the FOR
SERVICEMAN. Refer to "FOR SERVICEMAN/special function/preheating for floor" .

10.4 Pre-operation checks
