Mounting positions for the detector housing
In principle the detector housing can be mounted in the X, Y or Z axis. However, because of the labelling for the indicator ele-
ments, it is advisable to mount the device in the Y axis (vertical, control unit at the top). The sampling pipe is then inserted into
the detector housing from below. This makes it easier to feed the tubes to accessory parts such as filter-box/filter unit and wa-
ter retaining box, which for physical reasons should always be below the ASD detector housing. If feeding the sampling pipe
into the detector housing from above is unavoidable, the detector housing can also be rotated through 180° and then mounted
(i.e. with the control unit at the bottom). To ensure that control unit labelling is not upside down, turn the control unit labelling
strips accordingly (see Sec. 5.4.4).
To prevent the ingress of dirt, the detector housing ships fitted with the pipe plugs (tube network input). Likewise all the cable
screw unions are sealed. If there is a return sampling pipe back to the monitored area, it can be connected directly to the de-
tector housing in place of the air outlet pipe plug.

Warning about pipe entries
•
The entry opening in the detector housing is designed so that the sampling pipe simply has to be plugged into
place (conical opening). The sampling pipe should only be glued into place in exceptional circumstances and
only after consulting with the manufacturer.
•
The air outlet pipe plug (with openings) is to be fitted to the air outlet opening only.
•
The pipe plugs must not be glued in the ASD housing (plug-in connector).
