5. SHUTTING DOWN THE UNIT
5.1. EXTENDED SHUTDOWN
When the unit is stopped for a long time, it is recommended to turn off the power supply and lock the main
electrical disconnector to avoid accidental starting of the unit. A full inspection of the installation and unit is
recommended to ensure that everything is in order.
Before restarting the unit after a prolonged shutdown, we strongly recommend that you redo a visual
inspection of the unit and its surroundings, as well as the initial start-up procedure to ensure that everything is
working well and safely:

Make sure that the main electrical disconnector is in the "OFF" position.

Check the status of the filters, replace them if necessary.

Ensure that nothing partially or completely obstructs the air inlet and outlet.
 Make sure there is no stagnant water in the device.

Check that the wire connections are not loosened.

Move the main electrical disconnector in the "ON" position.

Ensure that the air inlet and outlet flaps are working properly and that the normal sequence of
operation of the unit is carried out.
5.2. EMERGENCY SHUTDOWN
When the unit shuts down in an emergency, the main electrical connection must be deactivated and locked
before the full inspection.
