MAINTENANCE
For every operation of maintenance, even replacement of filters, disconnect the electrical
supply before any operation and ensure that the unit cannot be started accidentally.
Maintenance of ventilation installation helps to avoid:
·microbial contamination of the installations, with consequences on comfort and health (the impact
of such contamination is aggravated in an air supply);
·loss of aeraulic performance through too high pressure drops, increase of fan consumption;
·noise (from a too high air speed, and from high speed rotation of fan due to clogged filters).
