6. Maintenance
6.1. General
Read the health and safety warnings in chapter 1.2.
 Note: The remote unit does not require preventative maintenance
measures.
 Note: To prevent malfunctions of the cooling system due to dirt or
pollution, it is recommended to clean the heat sink at regular
intervals. These cleaning intervals depend mainly on the location
of the remote unit and the corresponding degree of pollution.
Maintenance of the ION-U High Power RUs should be performed by replacing only
components that are described in this chapter. In order to maintain the warranty,
avoid unintentional damage to the seals on the modules.
The spare parts list, (see chapter 7.3) includes only units that can be replaced in the
field without tuning or soldering work.
 Note: When sending back the unit, use appropriate packaging. Use of
the original packaging for shipping the unit is strongly
recommended!
 Note: Defective parts should only be replaced by original parts from the
supplier. All service work performed inside the housing is
performed at the users own risk.
 Note: Ensure the Remote Unit has been disconnected from mains power
during maintenance.
 Note: Label any unlabelled cables before disconnecting them to ensure
correct reconnection.
For most maintenance procedures, appropriate tools are required to ensure correct
handling. All of these tools can be ordered from the supplier.
 Note: All Remote Unit screws have a right-hand thread, and are
tightened by turning the screws clockwise and loosened by
turning them counter-clockwise with an appropriate tool.
Due to the design of the remote unit, the fan unit is the only component that should
be replaced in the field. Please contact the supplier for replacement of any other
components.
