Start-up
General remarks
The cooling units are supplied “dry”, i.e. without any coolant in the reservoir. The coolant
is supplied separately, in two 5l canisters. Before using the cooling unit for the first time, fill
the reservoir with coolant!
Guarantee provi-
sions regarding
the coolant pump
The coolant pump may only be used with original coolant supplied by the manufacturer. Do
not allow the coolant pump to run dry (even for a very short time), as this will destroy the
coolant pump. The manufacturer accepts no liability for damage caused in such cases.
Information on
the coolant
Only use original Fronius coolant for the filling of the cooling unit. Other antifreezers cannot
be recommended due to their electric conductivity and compatibility.
