capacitor to discharge.
Check the electric connectors of the power source and RCM at least every six months. Clean oxidized parts and tighten
loose connectors.
Where applicable, use the correct tension torque when fastening loose parts.
Clean the outside parts of the power source from dust and dirt, for example, with a soft brush and vacuum cleaner. Also
clean the ventilation grill at the back of the unit. Do not use compressed air, there is a risk that the dirt will compact even
more tightly into gaps of cooling profiles.
Clean the outside parts of the RCM from dust and dirt, for example, with a soft brush.
Check the coolant filter every six months (depending on usage). Clean the filter and replace the filter mesh when neces-
sary.
