User manual TELEFUNKEN DPF 7900

[. . . ] Make sure that the inspection doors are available for maintenance/service. Leave free space for removing of inspection doors and main components inside the unit. If the unit is installed on a light wall construction towards a living room (f. Bedroom), we recommend that the wall is insulated/ designed so that transfer of noise is avoided. [. . . ] 5) Fresh air duct and discharge ducts must always be well insulated against condensation. Correct insulation installation on ducts connected to the unit is especially important. Use insulation sleeving (50 mm mineral wool) with plastic diffusion barrier. In areas with extremely low outdoor temperatures during the winter, additional insulation must be installed. Using another kind of duct system you should follow the enclosed instruction. Note: Even if the cookerhood is connected to the unit, a separate extract louver must be installed in the kitchen. Make sure that the air stream from inlet diffusers has a free passage. Air stream from inlet diffuser mounted on the wall (where the ceiling is horisontal), must have throw length, so that the air is supplied to the room alongside the ceiling. Air supply through extract louvers will ensure an air stream with throw length, and extract louvers can therefore be used as inlet diffusers when mounted in the wall close to the ceiling. Setting of air volume For basic setting of inlet diffusers, open core of the diffuser 5-7 turns from closed position. inlets to be connected to NO (normally open) , potensial free contacts. Contacts to DI5 and DI6 to be of type press buttons with automatic return. Pressure guard: If unit is to be provided with pressure guard for compensation of under pressure caused by separate ventilator, fire place etc. Reset of filter time: Reset of filter time may be done from DI6, using press button with automatic return. When choosing battery, the following aspects should be taken into consideration: Air speed through battery, using the whole surface of the battery, should be dimensioned for a velocity of 2-5 m/sec. Fluid velocity should not be less than 0, 2 m/sec to avoid problems with airing the system. Nor should it exceed 1, 5 m/sec in copper pipes or 3, 0 m/sec in steel pipes, to avoid erosion in the pipe system. Example of valve motor: Example of valve: Example of transformer: Regin type MVT57 Regin type VST (2-way valve) or VMT (3-way valve) Systemair 24V/PSS48 Das Gerät muß für den Betrieb mit WW-Register konfiguriert warden (Punkt 7 in separater Anleitung „Service Menu, Konfiguration”. The unit must be configured for operation with water heater, see item 7. Sensors marked “SS” (Supply air Sensor) and “OT” (Overheat Temperature sensor), to be disconnected and isolated, then to be replaced by a duct sensor type TGK360 (SS) and a “wrist watch” sensor type TG-A130 (Frost Protection Sensor, FPS) respectively. [. . . ] Sound attenuators are installed and that the duct system is correctly connected to the unit. Fresh air intake and discharge is installed so that short circuit of the air streams is 3. Fresh air intake is positioned with sufficient distance to pollution source (kitchen ventilator exhaust, central vacuum system exhaust or similar). The cookerhood is equipped with a damper leaving no opening in closed position (without opening for basic ventilation). [. . . ]
