1 Introdcution The RADONTEC ALPHAEX was developed for the underfloor extraction of radon gas. With a drainage underneath the foundation, radon-containing soil air is extracted over a wide area and conducted outside by negative pressure. With a so- called radon well in or near the house, the radon-containing soil air is extracted selectively and thus kept away from the walls of the house that are in contact with the soil. This prevents the radon from entering the building. The placement of the RADONTEC ALPHAEX outside the building can be freely chosen. The RADONTEC ALPHAEX is suitable for permanent outdoor use (IP X4 - protection against splash water from all sides and a temperature range of -25 °C to +50°C ). The built-in radial motor is extremely robust and designed for a long service life.

Application example 1: Point radon extraction with discharge at floor level.

Application example 2: Point radon extraction under the floor slab with discharge above the roof.

Application example 3: Extraction of radon soil air via an external radon well.

6 Bestimmungsgemäße Verwendung 6.1 Intended use The RADONTEC ALPHAEX fans are suitable for the following applications: ● RADONTEC ALPHAEX fans are suitable for both private and public/commercial use. ● These fans are used for the extraction/venting of soil air containing radon under buildings. ● Extraction of radon drainage systems. ● Connection to indoor radon extraction points (fan must always be placed outside the building). ● Connection to radon wells ● Connection to perimeter drainage systems (Caution: These must be dry. It must be ensured that no water can be sucked in). ● Permissible places of use are roofs (flat, pitched, corrugated or trapezoidal roofs), ceilings or consoles with sufficient load-bearing capacity. As well as installation close to the ground. ● A fixed installation with permanently installed electrical supply cable is mandatory: - With roof base only on a suitable substructure.

- Without roof base directly on the vent pipe. The fan is suitable for vertical mounting on the exhaust air ventilation shaft and may only be used for exhaust air ventilation. ● When connecting to pipes, transitions with elastic connecting pieces are recommended. These prevent vibration transmission to the pipe system. ● In the case of free intake (near the floor), operation is only permitted with contact protection in accordance with EN ISO 13857. We offer the matching protective grille for this as an option. (Must be purchased separately). 6.2 Non-permitted use RadonTec is not liable for damage caused by improper use. Do not use the unit under any circumstances: ● to convey air that is saturated with water vapour or contains grease ● in conjunction with an extractor hood ● for conveying dust particles, solids, sticky substances and dfibrous materials that may adhere to the fan ● in the vicinity of flammable materials, liquids or gases ● for conveying chemicals, aggressive gases or vapours ● in explosive atmospheres

● if there is no protection against contact with the impeller in accordance with EN ISO 13857 for free intake (near the floor) 7 Ambient conditions Maximum permissible temperature of the pumped medium + 50 °C, depending on the unit variant. When operating with room air-dependent fireplaces, sufficient supply air must be provided. The maximum permissible pressure difference per living unit is 4 Pa. 8 Safety notes Read these installation and operating instructions carefully before using the fan for the first time. Follow the instructions. Keep these instructions in a safe place for later use. Installation may only be carried out by skilled personnel with knowledge of ventilation technology. The electrical connection may only be carried out by qualified electricians. These have electrical engineering training and knowledge of the dangers and effects that can result from an electric shock. The installation personnel must be height- and foot-safe.

When working on the roof, sufficient safety precautions must be taken to protect the installation personnel. The degree of protection specified on the type plate is only guaranteed if the unit is installed as intended and the cables are properly inserted into the terminal box. Only connect the unit to a permanently installed electrical installation with cables of type NYM-O or NYM-J (3x 1.5 mm² or 5x 1.5 mm²). In addition, a device for disconnecting from the mains with at least 3 mm contact opening per pole must be fitted. Only operate the unit with the voltage and frequency specified on the type plate. It is essential to fit a repair switch at the installation site so that all poles of the unit can be disconnected from the mains on site during cleaning, maintenance or repair work. It must be possible to secure the repair switch against being switched on again. Only operate the unit when it is completely assembled. A sufficient supply air flow must be ensured. Modifications and conversions to the unit are not permitted and release the manufacturer from any warranty and liability.

Never operate the unit without a protective grille in the case of free intake (near the floor). Secure the unit and piping against foreign bodies being sucked in. Risk of injury from objects in the impeller. Do not insert any objects into the unit. Risk of injury from rotating impeller.
