If necessary, this cooling system will
automatically apply heat to the liquid
when following the user set-point. This
can become necessary if the set-point is
above ambient temperature and attached
heat sources are too weak to adequately
warm the coolant. An LED will illuminate on the front panel whenever heat is being
applied.
CAUTION:
To avoid permanent damage to the pump and other
cooling system components, do not allow the liquid temperature
to exceed 60°C (140°F) by set-point or other methods. This is the
maximum temperature supported by the cooling system.
