Install Bellow Assembly for EVT system
This article cover the replacement of the bellow assembly. Please see the EVT User Manual for more detailed information.
Before beginning any experiment, make sure to install/replace the Bellows Assembly only after the station has been powered up and in “home” position (LED light is on).
Installation of Bellow Assembly
Install a Bellows assembly into the Bellows assembly housing of the EVT Smoke Generator Station. Please be sure to add a little grease around the lower edge of the bellows assembly to prevent a leak. Grease and a small applicator swab are part of the EVT Station Accessory kit.
Verify Bellows Assembly is aligned with the Bellows Loading Line
Make sure the Bellows is compressed and aligned with the bellows loading line. If it's not, remove the bellows and adjust it or replace it. The bellows should be as close to the loading line as possible. Failing to do so could cause the bellows to "bottom out."
Calibration of the Bellows Assembly
The bellows assembly calibration is necessary to achieve accurate puff volumes. The calibration routine makes adjustments to the system to account for flow resistance and measured puff volume.
Before beginning an experiment, it is recommended that you calibrate each station and capture a puff volume measurement.
Please see the EVT User Manual for more detailed information.
