Performing maintenance
Performing maintenance
Carry out the specified configuration, maintenance and inspection work every
six months or, at the latest, when an error message or malfunction makes it
necessary.
Disconnect the FCU from the power supply when performing any
maintenance, inspection or repair work.
Once maintenance work is complete, check that the FCU is still working
properly.
Cleaning the FCU
Clean the control panel with a clean, moist cloth. Do not use any chemical
cleaning agents, as these may damage the film attached to the surface of the
FCU. Clean the outside of the FCU with a moist cloth.
Changing the FCU Filter Element
To change the filter, proceed as follows:
1. Turn the FCU so that the rear side faces
upwards. Ensure that the flow rate
control valve is not damaged.
2. Unscrew the sealing cover with a size 19
key by turning it counterclockwise.
