2.3 Delivery of Equipment
2.3.1 Receipt of Equipment
All equipment is inspected prior to despatch and leaves the factory in
good condition. Upon receipt of the equipment an inspection should be
made and any damage indicated on the delivery note.
Particulars of damage and/or incomplete delivery should be endorsed
by the driver delivering the goods before offloading by the purchaser.
No responsibility will be accepted for damage sustained during the
offloading from the vehicle or on the site thereafter. All claims for
damage and/or incomplete delivery must be reported to Nuaire within
two days of receipt of the equipment following guidance in our terms &
conditions of sale.
2.3.2 Offloading and Handling
The weight of the unit modules and palletised items is displayed on
the unit rating plate or on the packaging. Some of the modules have an
uneven weight distribution, and this will be indicated by labelling where
appropriate. Ensure that lifting and handling equipment is adequately
rated. Offloading and positioning of the equipment is the responsibility
of the purchaser.
Spreaders should be used when lifting with slings to avoid damage
to the casings. Care must be taken to ensure that slings are correctly
positioned to avoid crushing and twisting of the unit castings.

3.0 MECHANICAL INSTALLATION
Installation of the IAQ modules, including all external services and
controls should be in accordance with the appropriate authority and
MUST conform to all governing regulations e.g. CDM, CIBSE, IEE, and in
strict accordance with the applicable Building Regulations. These units
may only be mounted horizontally.
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 units are heavy, and should be mounted using the fixing brackets
supplied or other suitable methods of support. The supporting structure
must be assessed for structural suitability.
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 unit), or to other horizontal supports by others where wider
load distribution is required.
3.1 IAQM Layout Modifications
Depending on the installation requirements of the IAQM unit (e.g.
location, orientation, model variant, etc.), onsite modifications of the
module may be needed. Refer to the table provided for modification
requirements.

3.1.1 Switching Spigot Plates
If bottom access IAQM unit is to be close coupled to a right hand
configuration XBC unit, the IAQM unit inlet and outlet spigot plates
must be switched to ensure XBC ducting paths are clear. Detach both
IAQM spigot plates by removing the bolts securing the plate to the
IAQM unit. Exchange the inlet and outlet spigot plates and reattach to
the IAQM using the same bolts and fixing points.
