10.2.7 Check cooling coil
• Shut off the cooling­water supply.
• Disconnect the cooling­water 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If the cooling coil is dirty, heat is no longer withdrawn effectively from the gear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. These analyses are carried out by companies which
specialise in chemical cleaning. They also supply the special cleaning agents required.
• Before using these cleaning agents, ensure that they will not damage the coil materials (contact
FLENDER). 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 personal protective equipment (gloves, safety glasses)!
• Seriously contaminated cooling coils must be replaced. Consult our Customer Service.
• Re­connect the water in­ and outflow pipes.
