Check cooling coil
•
Shut off the coolingwater supply.
•
Disconnect the water in and outflow pipes from the cooling coil.
•
Check the inside walls of the cooling coil for deposits.
If the cooling coil is dirty, heat is no longer withdrawn effectively from the gear unit.
Any dirt adhering to the inside of the coil should be removed by chemical cleaning or
the cooling coil should be replaced with a new one.
•
If thick deposits have formed on the inside of the cooling coil, the cooling water and/or the deposits
themselves should be chemically analysed. Such analyses are offered by specialist companies for
chemical cleaning. Such companies also sell special cleaning agents for removing such deposits.
•
Before using these cleaning agents, ensure that they will not damage the cooling coil materials (consult
Siemens). Observe the manufacturer’s instructions at all times when using different cleaning agents
by several manufacturers.
Avoid burns when working with corrosive cleaning agents. Always observe the
manufacturers’ instructions for safety and use.
Wear suitable personal protective equipment (gloves, safety glasses)!
•
Seriously contaminated cooling coils must be replaced with new ones. Consult our Customer Service.
•
Reconnect the water in and outflow pipes.
