Drive Module Fan Replacement
The drive module fan cools the heatsink. Fan failure can be predicted by the increasing
noise from fan bearings and the gradual rise in the heatsink temperature in spite of
heatsink cleaning. If the drive is operated in a critical part of a process, fan replacement is
recommended once these symptoms start appearing. Replacement fans are available from
the factory. Do not use other than CentriPro specified spare parts.
To monitor the running time of the cooling fan, see “Group 29: Maintenance Trig” in the
Aquavar CPC Users’s Manual.
Frame Sizes R7 and R8
Refer to the installation instructions supplied with the fan kit.
