5. MAINTENANCE
5.1. GENERAL
Read the health and safety warnings in chapter 1.2 Health and Safety Warnings.
) 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-M7P/85P/17P/19P should be performed by replacing only
components that are contained in this chapter. In order to maintain warranty, take
care not to damage unintentionally the seals on the modules.
The spare parts list, consequently, contains only units which can be replaced without
tuning or soldering work.
) Note: When sending back the unit, use an appropriate packaging, see
chapter 6.2.3 Environmental and Safety Specifications. We
strongly recommend using the original packaging!
) Note: Defect parts should only be replaced by original parts from the
supplier. All interventions inside the housing are at one’s own risk.
) Note: During maintenance ensure the Remote Unit has been
disconnected from power supply.
) Note: Before disconnecting any cables, label any unlabelled cables to
ensure correct connection.
For most maintenance procedures appropriate tools are required to ensure correct
handling. All these tools can be ordered from the supplier. For screwing procedures
observe that all our screws have a right-hand thread, i.e. for fastening the screws
turn the tool clockwise and for unscrewing them turn it counter-clockwise.
Due to the design of the Remote Unit the only component recommended to be
replaced is the fan unit. For replacing any other component, please contact the
supplier.
