These products contain rotating parts and electrical connections, which can be a danger
and could cause injury. The axial fans utilised in the Short Case Axial range also generate
noise; it is advised that if activities have to be conducted in close proximity to the working
units the noise level should be taken into account. Taking the previously mentioned points
into consideration, it is advised that this unit should installed out of normal reach of
personnel.
In the event that the fan is installed in such a way that moving parts could be accessed
during normal operation i.e non-ducted, it is the installers responsibility to ensure that
guards and other relevant safety devices are used to ensure adequate protection for
personnel and property inaccordance with BS EN ISO 13857:2008 and EN 61140:2002.
Fans should be fitted to fixed circular duct flanges with M8 nuts and bolts with appropriate
screw locking. We recommend using VES flexible connections with strangle bands for
circular duct connections.
Fan mounting/hanging feet can be provided to secure short case axial fans in place.
The following installation guidelines should be followed.
Do not install Short Case Axial fans without adequate support. Mounting surface must be
even. Axial fans must be supported independently from ductwork.
Ensure that the clearance gap A (See Fig 2.) is constant between the fan impellor and fan
casework. Distortion due to uneven mounting surfaces may lead to fan failure.
The fans are only intended for the conveyance of air mixtures similar to air. Other uses
which do not coincide with, or which exceed those specified will be deemed unauthorised
unless contractually agreed. Damages resulting from such unauthorised uses will not be
the liability of the manufacturer.The user will assume sole liability.
They must not be used in hazardous areas for the transfer of gas, mist vapours or mixtures.
Nor must they be used for the transfer of solid components in the transfer medium.
