Installation Manual
3.10 Unit Installation
The ventilation unit must be installed first, with consideration
made for the length of the associated attenuators.
Installation of these units, including all external services and controls
should be performed in accordance with all appropriate site procedures,
and MUST conform to all governing regulations e.g. CDM, CIBSE, IEE,
and in strict accordance with the applicable Building Regulations.
The correct installation position for the units shall be decided with due
regard to access and maintenance requirements, and the objective of
minimising the system ductwork resistance.
The recommended installation method is to use standard Unistrut
channel secured to the slab / steelwork above the unit.
Four suitable drop rods should be secured to the Unistrut channel and
extended to be fixed to the unit’s four mounting brackets, (two each
side of the fan unit) or to other horizontal supports by others where
wider load distribution is required.
3.11 Attenuator Installation
It is recommended that additional Unistrut channels are used to
support the matched attenuators. M8 Drop rods should be secured to
the Unistrut channel and extended to be fixed to the four piece support
brackets to be used on the underside of the attenuators (Figure 15).
Note – once the attenuators are supported and levelled, and
immediately before securing the attenuator to the attenuator flange
connector, remove the backing from the Foam Sealing Strip.
The attenuators must be secured to the unit using the screws provided.
