of the motor/fan assembly for maintenance purposes.

standard brackets provided are suitable only for the more conventional

Where silencers are to be fitted to the unit (for all sizes except
SQF41), installation type A should be used to ensure silencer
splitters are vertically orientated (Figure 2). SQF41 silencers are
square and can be rotated to ensure vertical orientation in either
installation type.

with good industry practice and should conform to all governing and

produced, the details are also recorded on the fan side rating plate
which should also be referred to before handling and installation. Any
