Care, maintenance and disposal

General remarks

Under normal operating conditions the cooling unit requires only a minimum of care and
maintenance. However, it is indispensable to follow some important points to ensure the
operationality of the welding machine for many years.

Safety

An electric shock can be fatal.
Before opening up the machine, switch it off, unplug it from the mains and put up a
clearly legible and easy-to-understand warning sign to stop anybody inadvertently
switching the machine back on again. The casing screws are a suitable protective con-
ductor connection for grounding the casing. The screws must not be replaced by other
screws without reliable protective conductor connection.
Danger of scalding from hot coolant fluid.
Do not inspect the coolant connection points until the coolant has been allowed to cool.
IMPORTANT!
The coolant must not be disposed of via the sewerage!
NOTE!
For refilling the cooling unit only use coolant of the manufacturer.
