Chapter 8 • Mounting and connection of pneumatic components User Manual Series F-BO-AFE708 Mounting and connection of pneumatic componentsThis chapter describes the mounting of the Purging unit, the connection to the sampling pipe sys-tem as well as the aspirating smoke detector and the compressed-air connection.Pay attention to the danger notices given on page 3.Beware of static charges! The electronic components used in the Automatic Purging UnitF-BO-AFE70-2 can be destroyed by static charges when the device is open. Before and duringthe work being performed on printed circuit boards, static charges from your body must be reli-ably discharged by touching an earthed piece of metal.8.1 Location of installationThe Purging unit must be installed in a clean room on a stable wall surface. The room temperaturemust range between +5°C and +50°C in the immediate vicinity of the Automatic Purging UnitF-BO-AFE70-2, and between -20°C and +40°C in the immediate vicinity of the F-BO-AFE70-3;the relative humidity of the air must not exceed 95% at 40°C.Within certain limits, the temperature range can be extended; please ask your supplier or the manu-facturer about it.Bear in mind that the life span of the components may be reduced by high temperature andhumidity. Therefore, it is recommended to install the Purging unit in an environment with a nor-mal indoor climate (i.e., up to a maximum of +40°C), if it is possible.The pipe connection between the Automatic Purging Unit F-BO-AFE70 and the evaluation unit ofthe aspirating smoke detector should be as short as possible. Please note that this connecting pieceis not cleaned during the „Purging process“!8.1.1 Permissible mounting positionsFig. 6: Schematic illustration of the permissible wall mounting positions of the Automatic PurgingUnit F-BO-AFE70 together with the evaluation unit and the pipe system of the aspirating smokedetector.A … Mounting position with downward air flow in the direction of aspiration (compressed-airconnection at the bottom)B … Mounting position with upward air flow in the direction of aspiration (compressed-air con-nection at the top)C … Mounting position with air flow from the left to the right in the direction of aspiration (com-pressed air connection at the bottom right)However, the mounting position with air flow from the right to the left in the direction ofaspiration (compressed-air connection at the top left) is not permissible!I56-4252-010D200-104-0024
