AEROFOIL AXIAL - FLOW FANS ATTENTION! Only approved, qualified personnel familiar with the assessment of hazards and risks associated with fans, and with the use of tools and test equipment required to service such fans, should install, operate and maintain the product. ATTENTION! If the installer or user is unable to understand the information in this manual, or has any doubt that a safe and reliable installation, operation and maintenance of the equipment can be assured, Fläkt Woods limited or their representative should be contacted for advice. ATTENTION! Warnings and safety information...

4. MECHANICAL INSTALLATION ATTENTION! It is recommended that suitable safety guards form part of the Installation. Such devices, and advice on safety devices, are available from Fläkt woods limited. ATTENTION! Where the fan is delivered in a crate (or similar), the crate must be considered as a protective device only, and must not be used as a lifting aid unless otherwise indicated. ATTENTION! ll lifting aids used during installation should be adequately certified to carry the weight of the A equipment being lifted. ATTENTION! Always wear appropriate protective clothing (including hard...

5. ELECTRICAL INSTALLATION & OPERATION ATTENTION! No work should be attempted before completely isolating the fan assembly, its anti-condensation heater (if fitted), and its controls from all electrical supplies, and allowing the rotating parts of the fan to come to rest. ATTENTION! Before entering the area ensure that all fumes, dust, toxic emission, heat etc. have dispersed from the local environment, and the fan blades are not likely to windmill. ATTENTION! The fan assembly contains rotating parts and electrical connections which can be a danger and cause injury. If there is any doubt...

5.1 CAPACITORS (SINGLE PHASE MOTORS ONLY) Physically small sized capacitors are mounted on the motor during manufacture. Larger capacitors, are supplied separately and must be fitted externally from the motor. Capacitors for hazardous area motors must be located outside the hazardous area. ATTENTION! Be aware that electrical components can operate at high temperatures. Keep Flammable Materials away from these and their connections. Whilst it is extremely rare, the possibility of component malfunction should be taken into consideration. 5.2 OVERHEAT PROTECTION Motor overheat protection (if...

Great care must be taken to ensure that the thread of cable glands, or conduit, matches its corresponding thread so that the entire installation achieves the level of protection required. Long cased, fully ducted fans fitted with ENV89 motors are not fitted with an external terminal box. The supply cable to the motor terminal box must be fed through the conduit hole in the fan duct and connected into the terminal box before the fan is fully installed (i.e. before the inlet and outlet ducts are fitted). Any electrical control gear (including the capacitor in the case of single-phase motors)...

Thread forming screws must have locking compound applied when being reused. Those fixings that have no locking devices fitted and are not painted over, should be checked at 95% of their original setting to ensure no unnecessary disturbance of the fixing. See Figures 6 and 7 for torque setting details. If in doubt about the torque of a particular fixing contact Fläkt Woods Limited for advice. 6.2 LUBRICATION In addition to routine maintenance motor bearings will in the longer term require attention. If the motor bearings are greased through extended lubricators, a quality of grease should be...

8. FAULT FINDING Please refer to the safety warnings (“attention” items) stated within paragraph 6. NOTE! The routine maintenance procedures detailed in Paragraph 6, and Table 1, of this document are designed to help keep the fan operational and fault free. 8.1 ELECTRICAL Check that the electrical connections to the unit are secure. Check that the voltage applied at the fan terminals is as specified on the motor nameplate, and is balanced. Measure the current on each phase (one phase in the case of single-phase motors) of the motor in turn and check that the current consumption is within...

10. EUROPEAN MACHINERY DIRECTIVE 2006/42/EC 1.7.4.2 CONTENTS OF THE INSTRUCTIONS CLAUSE C) Please see a typical example of an EC declaration of conformity certificate (below), which shows particulars of the machinery offered. CLAUSES G) AND H) Fans should not be operated above maximum speed indicated, or run where the fan is operating in a stalled condition. Fans should also not be run in reverse unless specific advice is sought from Fläkt Woods. CLAUSES I) AND J) Fans should be isolated from support structures by means of anti-vibration mounts and from adjacent ductwork by flexible...

Routine Maintenance Schedule 1. Examine the airways in to the fan guards (if fitted) Remove and debris that may have accumulated round the guards 2. Examine motor cooling fins Remove any material / dirt build-up between the motor fins 3. Examine impeller for dirt build-up or any physical damage Remove any build-up of dirt. Ensure impeller is secure. Replace impeller if it is damaged 4. Check condition and tautness of fan safety support chains / harnesses / ropes (if fitted) Clean safety supports. Replace them if there is any deterioration / corrosion 5. Examine and operate vibration sensors...
