Recirculation - CDA EVX90SS Use And Maintenance

Recirculation

An internal air vent is required, as shown below. This ensures
that the air is placed back in the kitchen after it has been
filtered. The internal air vent must be a minimum of 2 metres
away from the extractor
Extraction
The extractor is provided with a non-return butterfly valve which
should be fitted over the vent outlet before the ducting is fitted.
This prevents cold air being blown into the room from outside.
Securing the duct to the outlet
Note that the duct pipe should be secured and sealed to the
vent outlet pipe/valve using appropriate ducting tape or a
securing clamp.
