5 How to maintain
5.1 Fan maintenance
ESS fan’ expected life-span is 70000 hours under continuous working. The higher
ambient temperature is, the shorter life of service of the fan. Check the fan
regularly in every year to see the fan is working well or not, make sure there is air
blowing out from the outlet of the system.
Note : Shut down the fan before maintenance, so as to avoid personal injury and
device damage caused by electric shock and fan blades rotation at high speed.
5.2 Clearance
Regularly clear the whole system, especially ventilation hole, ensure air free flow
in the housing, use vacuum cleaner if necessary, make sure no dust and other
sundries hindering the ventilation of the system.
Note : Shut down the fan before cleaning, so as to avoid personal injury and device
damage caused by electric shock and fan blades rotation at high speed.
5.3 Fault handling
