Before opening the dehumidifier, make sure the power is turned off at the mains before you open any cover.
Otherwise, there will be a risk of electric shock. Also, be aware that the heater element may be hot if the lid is
removed immediately after turning off the dehumidifier.
Service and maintenance work on this dehumidifier
Cotes designs its dehumidifier units so that they are as robust as possible, requiring only minimal service and
maintenance. None of the components require lubrication or adjustment. The only maintenance work you need
to do is listed below. Keep the service area clear at all times and make sure diagrams and manual are kept near
the machine. The machine will automatically start up in case of power loss and recovery of electricity.
It is strongly advised to keep an 'Inspection and Maintenance Log' containing validations and observations from
inspections and maintenance.
Service and maintenance in wind turbine installation
Only three items should be done during normal operation and following the normal service intervals
for installation in the nacelle and tower of a wind turbine:
• Replace air filters.
• Check the rotation of the rotor.
• Check the power consumption of the electric heater according to the table with recommended values.
If the rotor rotates during operation, and the energy consumption is correct, you can be almost certain that the
dehumidifier is operating at its optimum.
Nevertheless, we recommend some periodic verification of the entire dehumidifier, to see if all internal functions
are functioning correctly, check that cables are securely fixed and inspect for any damage to the insulation.
