4 Maintenance
One of the biggest advantages of the MicroDC is the very low
maintenance cost needed in order the system to operate and
function as brand new.
4.1 Cooling device
Caution! Before embarking on any maintenance work,
switch current off of the cooling unit.
The cooling unit is a low maintenance type; so no filter change
is required. The main job that regularly needed to be done is
to blow the internal components with compressed dry air at
a maximum pressure of 4 bars; the following also shall be
checked regularly:
Job
Check the external air to air heat exchanger
and clean if necessary
Check effectiveness of the condensate dis-
charge hose to check whether it has been
blocked or not
Check the fans for any overheating signs or
paranormal vibration
