User Manual Series F-BO-AFE70 Chapter 5 • Final assembly, mechanical structure and dimensions5 Final assembly, mechanical structure and dimensions5.1 Final assemblyFor reasons of safe transport, the pipe connecting components are enclosed and still have to beinstalled.Figure 4 gives an overview of the structure of a Purging unit after final assembly.In order to assemble the device, proceed as follows:Remove the two M3 screws from the cover and lift the cover of the Purging unit.Screw a pipe nipple G3/4“×34mm by hand into the thread of the 25mm push-in fitting as far as itwill go and completely push the plastic gasket Ø32mm×10mm onto the pipe nipple.Remove the protective cover from an opening of the housing; keep the protective cover for lateruse.Now screw the part of the pipe nipple's thread that protrudes from the plastic gasket by hand intoone of the two fitting threads of the Purging unit's body as far as it will go.Use a wrench of the right size (wrench size 32mm) to turn the 25mm push-in fitting by approxim-ately another 30° until it seats tightly and seals perfectly.Repeat the procedure described above for the other side of the Purging unit.Cover the openings of the 25mm push-in fittings with the protective covers and only remove theprotective covers just before connecting the sensor pipe network.By carrying out this step, the final assembly has been completed.It must be ensured that after final installation of the Purging unit, no push-in fitting can beloosened by hand, and that all push-in fittings are perfectly sealed. Therefore, check thetight seat of the push-in fittings after final assembly and prior to commissioning.You must never use any glue for the connections of the sampling pipes on the Purging unit andon the aspirating smoke detector.The warranty claims shall terminate in case of violation of this rule.I56-4252-010D200-104-0019
