SHUTDOWNS FOR LONG PERIODS
If the unit will not be used for a long period it is suggested to drain the water tank through the appropriate
valve. For the restart, please follow all the instructions and precautions given of this manual.
If the temperature drops below zero there is serious danger of frost: provide a mixture of water
and glycol in the system, otherwise drain the plumbing and the water circuits.
CAUTION: even temporary operation with water temperatures below +5°C is not guaranteed on
the basis of the limits established for the Vitocal 100-A units. Before you turn the unit back on
after a long idle period, make sure that the temperature of the mixture of working fluid is higher
than or at least equal to +5°C.
