VENTILATION THE RIGHT WAY

V E N T I L AT I O N & H E AT R E C O V E R Y

tored in addition to the mixed gas/CO

concentration (see section 10.7). The mixed gas/CO

sensor

and the humidity sensor each send feedback to the ventilation unit, indicating the ventilation level

at which it should work. The ventilation unit automatically assumes the higher of the two suggested

ventilation levels.

NOTE

—

When it is started up for the first time, the ventilation unit must remain switched on for at

least 4 hours without interruption so that the mixed gas/CO

sensor can be calibrated.

►

Make sure that the air is not severely contaminated during the calibration phase by

solvents, for example.

—

When you switch on again, it will take roughly 15 minutes for the sensor to recalibrate.

11 Filter maintenance

The ventilation unit monitors the level of soiling in the round filter cartridges and the time since the

last filter change. If the air filters are dirty or were last changed more than one year ago, the pend

ing filter change is signalled both audibly and visually (see section 10.2 on page 21).
As the time for the filter change approaches, the intervals between the audible warnings shorten

over a period of two to three weeks. The filters must be changed when the warning signal occurs

every hour and lasts for one second. This long warning period allows the user to order replacement

filters in good time. No tools are needed to change the filters.
