HIAQMInstallation Manual
2.0 INTRODUCTION
The Haven IAQ Module range of ancillaries has been specially designed
to complement the existing commercial range of XBC+ units as well as
providing a general function of high grade filtration to any commercial
ventilation units which require it. The unit shall be manufactured
from Alu-zinc with double skin panels filled with insulation to provide
thermal and acoustic barriers. The units will come as standard with
pressure monitoring for the filtration and give a relay output for alarm
signalling when a pre-determined pressure value is exceeded. The
units will be available with different access options (Bottom or Side
access) as well as weatherproofing and coastal varieties depending on
installation location. The unit is unhanded with different operations
to suit it for different installations available in this literature. Further
information regarding performance and specifications for the
equipment may be obtained from our technical literature, and/or
project specific documentation.

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.
4 Unit Lifting
Palletised.
Slings via spreaders fitted to unit with base frame.
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.

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.

3.2.1 Dirty Filter Pressure Switch Wiring
The cable gland is designed for cables with alternative sheath diameters
of 8 - 10 mm. Only use these sizes, otherwise the screw cable
connection cannot seal adequately. The connections are intended for
6.3mm crimp-type sockets.
•Remove switch cover.
•Wire the main unit to the terminal block within the switch as per
the below wiring diagrams (Figure 12) ensuring the feed line is
fused to suit Max 1.5A / 250 Vac.
3.1.2 Attaching XBC Flange
To aid in installation where IAQM units are to be close coupled to a
matching size XBC unit, the double (Supply & Extract) flange connector
of the XBC unit should be removed from the XBC and fitted to the
IAQM unit’s inlet along with the extract leg ducting. The full assembly
of IAQM unit, XBC flange connector and extract ducting can then be
raised and connected to the XBC unit. For further details see "Flange
Connector Dimensions (mm)" section, located in XBC+ installation
manual provided with XBC+ units.

3.1.3 Rolling IAQM Unit
If a side access IAQM unit is to be close coupled to a right hand
configuration XBC unit, roll the IAQM unit 180° to ensure XBC ducting
paths are clear.
Where a roof is supplied with the IAQM the roof should be removed
by unscrewing the 4x roof mounting points (2x M8 hex bolts) before
rolling the unit and reattaching the roof using the same 4 roof
mounting points.
Where an IAQM has no roof, the 4x mounting brackets provided can
be also be removed (2x M8 hex bolts) and reattached according to the
required mounting method if needed.

3.1.4 Relocating IAQM Roof
Due to the XBC roof overhang, an IAQM with roof cannot be close
coupled to an XBC unit with roof without relocating the IAQM roof
prior to installation.
Unscrew the M8 hex bolts attaching the IAQM roof to the 1st and 2nd
roof fixing points. Slide the IAQM roof away from the IAQM inlet and
utilize the 2nd and 3rd roof fixing point to reattach the IAQM roof.

3.2.2 Setting Dirty Filter Switch Pressure
Nuaire recommend the pressure switch be set to trigger when the
filters experience a 125 Pa increase above the clean filter resistance for
the largest commissioned airflow rate. Use the adjustment dial to set
the pressure at which the switch will trip. When the pressure falls below
this set value, the switch returns to its resting position.
4.0 MAINTENANCE
It is important that maintenance checks are recorded and that the
schedule is always adhered to, in all cases, the previous report should
be referred to.
4.1 Carbon Filter Maintenance
After a period of time, activated carbon in filter cells will become
saturated by odour, gas and chemical vapour contaminants and will
require replacement in order to maintain the filtration efficiency of the
carbon filter. HIAQM Carbon Filters have a lifespan of 2 years under
normal conditions. However, under certain circumstances, such as
highly polluted air, carbon filters may need to be replaced on a more
frequent basis. Contact Nuaire for accurate assessments of carbon filter
lifespans.
4.2 Routine Maintenance
•Clean all areas of unit and treat any areas of corrosion.
•Check all access doors for leakage and if necessary locks should be
adjusted and any replacement gasket materials should be replaced
as required.
4.3 Every 3 Months
•Check filters and change/clean if required, failure to do so may
impair the performance and energy efficiency of this unit.
4.4 Annually
•Thoroughly inspect the unit and its components for corrosion,
acting immediately to treat/restore any damaged areas.
4.5 Replacement Filters
To check the filter type within a unit refer to the module product label.
Replacement filters can be purchased direct from Nuaire using the
below code format.
