Connection
Attach two 45° pipe elbows on both sides (not supplied as standard) in order to achieve the
optimum distance from the wall for mounting the brackets. When installing, note the correct
direction of flow (see arrow on plastic container).
Also fasten the water separator with two screws and the clamp.
To empty, open the drain valve (see Section 7.12 Maintenance Intervals, page 92).

Test Adapter

Figure 5.10 Installing the test adapter in the pipe system
For test purposes, the pipe system connection is simply pulled out and the test pipe
connected directly to the aspirating smoke detector. However, this is not possible if the
aspiration pipe system has to be permanently mounted. A test adapter should be used for this
application.
