Installation (Mechanical) - Woods EC BOX FAN Safety, Installation, Operation And Maintenance Instructions

3. INSTALLATION (MECHANICAL)

3.1 It is recommended that suitable safety guards form part of the installation wherever necessary.
3.2 We recommend that an air filter is fitted within the ductwork to reduce the accumulation of dirt on the fan
impeller. An excessive build up of dirt could lead to imbalance of the impeller and vibration problems.
3.3 Where the product is delivered packaged, the packaging must be considered as a protective device only,
and must not be used as a lifting aid unless otherwise indicated. During lifting all personnel must be clear
of the area below the suspended fan.
3.4 An airflow indication arrow is shown on the fan nameplate. Sharp bends in the ductwork close to the
fan must be avoided. Adequate room must be allowed round the fan for safe inspection and future
maintenance, and the environment must be safe for both the fan, and for personnel.
3.5 Care must be taken to ensure that during extremes of wet and windy weather any ingress of water
through the fan will not reach sensitive or hazardous areas within the building.
3.6 The component parts of the product, including anti-vibration mounts, flexible connectors (and their clips),
weather proofing, platforms, supported drop rods and chains etc (if fitted), must be fully aligned before
being bolted together so that no distortion or stress is placed on the equipment.
3.7 A minimum of 8 x M8 bolts, with the correct torque applied, must be used to secure the fan into position.
The final position of the fan must be strong and rigid enough to take the weight of the fan and any other
weight applied during installation.
3.8 Lagging should be applied between the box fan and silencer, around the connecting joint, to ensure
maximum acoustic damping.
3.9 The product can be slightly tilted (to a maximum of 10 degrees) when used externally so that water runs
off lid.
