User Manual Series F-BO-AFE70

Chapter 1 • Introduction

Pay attention to the danger notices given on page 3.

Beware of static charges!

The electronic components used in the Automatic Purging Units

F-BO-AFE70 can be destroyed by static charges when the device is open. Before and during the
work being performed on printed circuit boards, static charges from your body must be reliably
discharged by touching an earthed piece of metal.

Scope of delivery

The Automatic Purging Units F-BO-AFE70 are assembled at the factory and supplied 100% func-
tion-tested. Only the pipe connecting parts have been enclosed for reasons of safe transport and still
have to be installed. Please check the delivery for completeness and transport damage before
assembling the equipment.

The delivery scope of the Automatic Purging Unit F-BO-AFE70 includes:



the valve block (with flange-mounted solenoid valve) that has been mounted on the bottom
plate and has been completely assembled and tested, including the mounted control board
AFS70-1, with protection cover (i.e., the housing) and cover.



two 25mm push-in fittings for the connection to the sampling pipe



two pipe nipples G3/4“×34mm



two plastic gaskets Ø32mm

this User Manual



an end-of-line resistor 5.6kOhm (for the line-monitoring of the fault output of the evaluation
unit of the aspirating smoke detector)



mounting material (three screws and three 6mm plugs for wall mounting)



three cable ties



transport packaging.

The Purging unit weighs approx. 3.2kg – the sturdy transport packaging has been designed to
avoid transport damage to any part. If the packaging has been damaged, you must inspect the
Purging unit especially thoroughly.
