Table of contents A Technical data B Warranty C Safety D Installation E Start of operation F Maintenance G Spare parts list H Manufacturer declaration C Safety Following safety instructions must be carefully followed with regard to preventing injury or damage to surrounding equipment and to the fan itself. 1 Suction Warning! Axial fans have high suction power. Objects, clothing and hair can easily be sucked into the fan and cause injury. Make sure that there are no persons nearby the inlet side when the fan operates. Protection guard may be removed only if it is replaced with a house or pipe of at least 1m. The fan must never operate without a wire guard because the rotation impeller can cause serious injury. 2 Discharge side Warning! There is a powerful stream of air from the discharge side. Foreign bodies that might have been sucked into the fan can be thrown out at high speed and cause injury. Never put the hand directly at the discharge opening. 3 Temperature Warning! When the fan operates the fan housing takes the temperature of the conveyed media. If the fan housing temperature exceeds 50°C the fan must be protected from direct contact to prevent burn injury. 4 Electrical connection Warning! Electrical connection must be made by skilled labour only. The drive motor should be protected with an overload switch. A Technical Data Following data is for the fan in its basic form, however, delivered fan can differ from the basic form. See the mark sign or the text "Special execution". Bifurcated axial fan in tubular version, with motor isolated from the air stream. Fans type AFH has casing of stainless steel and impeller of cast aluminium, and should only be used for conveying clean media. The temperature of the conveyed medium may not exceed 150°C. It is not permitted to use the fan in surroundings where the temperature exceeds 40°C or goes below -20°C. Conveying of explosive gases is not permitted. It is not permitted to rebuild or in any other way modify the fan. Special features that can be used in other surroundings than above can be offered on request and clarification with the manufacturer. Rating plate 5 Permitted applications Warning! AFH-fans are not to be used for conveying aggressive, toxic or air with high humidity or gas or explosive air-gas mix. 6 Sound level The sound pressure level is not the same over the whole range on the fans. In some cases it is necessary to use a silencer. We recommend the user to check the sound pressure level. D Installation 1 Transportation Check all parts for damage during transportation and that the impeller runs free inside the housing. The blowers are to be installed in weather-protected places and are not to be stored unprotected outdoors. Mount hoisting hook carefully, and do only use lifting arrangements with sufficient strength. 2 Arrangements and assembling Mount the fan horizontally or vertically in a weather-protected place. Make sure that the fan is protected from vibration and shock. Supply open inlet and discharge openings with guards according to valid regulations.
