INITIAL START-UP AT LOW OUTDOOR TEMPERATURES.

During the initial start-up and when the water temperature is low, it is important to heat the water gradually. Otherwise
the concrete floor could crack due to rapid temperature excursions. For further details, please contact the person in charge
of making the concrete floor.
To perform this operation, the minimum set flow temperature of the water can be reduced to a value between 25°C and
35°C by adjusting it on "FOR SERVICEMAN" (for the maintenance technician).
