Never operate the testo ASET15-1 with open additional evaporation tube inlet
port 32). This port is only used for calibration issues. Any air or aerosol flow on
this port will influence the dilution conditions in the device. If the port is open
during operation, the environment of the unit may be contaminated by escaping
aerosols.

Installation and Setup
Note: Numbers
– e.g. 8) = secondary dilution setting potentiometer – refer to the operating
elements illustrated in chapter 4.5.
The testo ASET15-1 Air Supply / Evaporation Tube is a secondary dilution unit and cannot be
operated without an inserted primary testo MD19-3E Rotating Disk Diluter.

Integrating testo MD19-3E into the testo ASET15-1
The testo ASET15-1 without any primary diluter integrated is shown in Fig. 5.1. The testo MD19-
3E Rotating Disk Diluter can be plugged into the testo ASET15-1 housing if the pneumatic ports
at the rear side of the plug-in are equipped with the quick couplings shown in Fig. 5.2 .

The control unit of the primary diluter is plugged into the testo ASET15-1 housing and fixed with
six screws located at the top and the bottom of the testo MD19-3E front panel. To remove the
testo MD19-3E from the testo ASET15-1 these screws have to be solved and the unit can be
pulled out.
