Replacing the heat exchanger fan
Replacing the fan
The typical service life of the fan is 50,000 hours. In practice, however, the service life
depends on other variables (e.g. ambient temperature, degree of cabinet protection, etc.)
and, therefore, may deviate from this value.
The fans must be replaced in good time to ensure that the device is available.
Preparatory steps
● Disconnect the drive line-up from the power supply
● Allow unimpeded access
● The pressure in the liquid circuit should be reduced so that the opening and closing of the
quick couplings is simplified.
