Dimensions · Installation Choice of unit The valve is selected on the following data base: static pressure drop Δps (Pa) basic air volume rate ‡o (m³/h) operating air volume rate ‡ (m³/h) Technical characteristics Nominal voltage: Power consumption, operation: Max. ambient temperature: Nominal diameter: The static pressure drop and only one of the two air volume rates can be freely selected. The following details can be found in the diagram: - number of rotations - residual air volume rate - acoustic data Please note that the respective operating air volumen rate characteristic must be taken...

Installation Adjusting of the basic air volume rate ‡o 1 2 3 4 5 Valve housing Valve disc Electro-thermal drive Tappet Knurled nut The automatic exhaust valve is closed by delivery (basic air volume rate ‡o = 0 m³/h). To set the valve to the basic air volume rate, proceed as follows: Place the exhaust valve on a firm base, e.g. a table, as shown and loosen the brass knurled nut «5» clockwise approx. by one rotation. Hold the exhaust valve at the electric drive and, with one finger of the free hand, rotate the valve disc «2» anticlockwise by the required number of rotations. Place the exhaust...

Electrical Connection Location of the electric cable It is best to lead the cable into the round air exhaust ducting. Plug «A» can be removed from the plate «C» after removing the central screw «B». With the central screw «B» removed from the plug «A», the insert «F» can be forced out with a screw-driver at the point marked «D». C Plastic tube (e.g. KRF 11), position: side or top Connection diagram P = Phase conductor N = Neutral E = Earth P IP54 EC, SEV approval, specially-insulated equipment with splash-protection
