Recirculation Mode

eM2 d 8.08.004

Press the recirculation button to prevent dusty or smoky air from entering the cab or to decrease the time required to cool or heat the cab interior during extreme outside temperature conditions. When recirculation mode is active the LED next to the recirculation button as shown, see Fig.. illuminates.

To prevent the buildup of odors or oxygen depletion inside the cab, after 20 minutes the system switches from full recirculation mode to partial recirculation mode for five minutes. The system cycles from full to partial recirculation as long as the mode is enabled.

Recirculation mode is not available when the air vent selection is set to partial or full defrost mode.
