Maintain the heat recovery system
Deposits in the heat exchanger can significantly reduce its capacity to transfer heat.
Check the heat exchanger regularly for leaks and contamination. Frequency of checking is depend‐
ant on the characteristics of the heat transfer medium.
Pressure in the cooling oil circuit is generally higher than that in the heat recovery system. If a leak
occurs, oil will run into the heat-receiving medium. Increased cooling oil loss can indicate a leaking
heat exchanger.
Precondition Cut-off the electrical power supply via the power supply isolating device,
