User manual BOSCH WTV74105GB INSTALLATION INSTRUCTIONS

[. . . ] – The outlet for the exhaust air duct must be no more than 2. 5 m higher than the exhaust air opening on the appliance. 1. Back panel connection The exhaust air opening on the back panel is open when the dryer is delivered (bayonet ring). The exhaust air opening on the left side panel is sealed with a cover. Safety instructions – We recommend that you route the exhaust air directly into the open air through an exhaust air duct. – Where an exhaust air duct is routed to the open air, a drain check valve must be fitted (prevents air from flowing back). – Only install the air extraction system as described in these instructions. [. . . ] gas-fired heating systems, gas-fired boilers, coal-fired ovens connected to a chimney, or open fireplaces, a vacuum may be created, leading risk of poisoning. to waste gases being sucked back – In every case, have safe operation confirmed by the responsible chimney sweep, boiler engineer, ventilation specialist, etc. Condensation outlet If there is a high level of condensation in the exhaust air duct, it is advisable to fix a condensation collector (standard) or a drain hole with a diameter of approximately 3 mm to the lowest part of the exhaust air duct. Installation for pipe connection - inside diameter = 100 mm If the pipe connection has an inside diameter > 100 mm and a total pressure loss greater than 50*, increase the inside diameter of the pipe connection page 6. * To determine the total pressure loss see table 1 2 3 4 Notes on installation Individual pressure loss values Pipe connection diameter > 100 mm Internal wall Pipe, smooth Flexible pipe, grooved Flat duct connection 220 x 54 smooth Installing more than one dryer Up to 7 exhaust air dryers can be connected to an intercepting pipe with a smooth internal wall. The following points MUST be observed: – It is imperative that there are drain check valves in the interception pipe for every dryer. These valves prevent the moist exhaust air from flowing back into the washing and drying room through dryers which are not in operation. – The outlet for the exhaust air must be arranged/routed in such a way as to prevent any additional backpressure (e. g. from a direct ingress of wind) on the escaping exhaust air. – In every case, have safe operation confirmed by the responsible ventilation engineer/ installer.
