IAQBOX
Indoor Air Quality Box
Installation and Maintenance
1.0 Introduction
Nuaire’s range of inline carbon supply filters has been specifically designed
to reduce the level of airborne contaminants entering a building, in particular
nitrogen dioxide (NO2), thus improving indoor air quality (IAQ). The filter unit
incorporates a carbon filter and a range of particulate pre-filters are available.
Units should be fitted on the supply leg of ducting and therefore do not require
insulation (see fig. 3).

3. Optional Particulate Pre-Filter:
PM10 = Removal of particular matter (10 microns +)
PM2.5 = Removal of particular matter (2.5 microns +)
1.1 Particulate Filter (Optional)
High urban PM (Particulate Matter) emissions may require an additional filter to
meet air quality standards.
1.2 Performance Data
Nuaire’s carbon filters have been independently tested and offer up to 99.5%
reduction in NO2. The unit meets planning obligations and world health
organisation's recommendations.
1.3 Resistance Data
When selecting the MVHR unit please ensure that the resistance through the
carbon filter has been allowed for. Please see www.nuaire.co.uk/iaqbox for
further details.

Installation and Maintenance IAQBOX - Indoor Air Quality Box
2.0 Installation
Installation must be carried out by competent personnel, in accordance with
good industry practice, the appropriate authority and in conformance with all
statutory and governing regulations.
The mounting surface must be of a solid construction and capable of supporting
the full weight of the unit.
Units are supplied complete with a mounting bracket for quick and easy surface
mounted installation.
Access to the unit for maintenance is granted via the bottom panel. Ensure
that an access panel has been allowed for maintenance to the unit, the space
required is shown below.
2.1 Choosing a Spigot (IAQBOX-D Only)
Refer to the system design drawing for the spigot configuration requirements for
each installlation.
Once the required spigot configuration is known, the relevant aperture(s) can
be cut out. Fix the required spigot(s) to the unit with the self-tapping screws
provided and seal with silicone to eliminate air leakage.
If choosing the single spigot configuration, the aperture that is not required
must be sealed off with the blanking plate provided. Fix the plate with the self-
tapping screws provided and seal with silicone.
2.2 Ceiling Mounting
•Remove unit from packaging and unscrew the outer locking bolts (two
bolts on the left and right side of the unit) from the mounting bracket,
storing them for later use (see fig. 4).
•Loosen the inner mounting bolts and slide/lift the mounting bracket off the
unit (see fig. 5).
•Locate the mounting bracket into the desired position, with the arrows
pointing in the direction of airflow. Use the bracket to mark the required
drill holes.
•Using the appropriate fixings, secure the bracket to the ceiling.
•Check the orientation of the unit matches that of the mounting bracket by
aligning the direction of the arrow on the bracket with the direction of the
arrow on the units’ airflow label.
•With the inner mounting bolts still protruding from the unit (5mm), offer
the unit up to the mounting bracket, sliding up and across so that all four
bolts rest in the bracket slots. Tighten all bolts.
•Lock the unit in position by refitting the outer locking bolts that were
removed earlier.
2.3 Limited Access
It is possible to fit this unit close to a wall/obstacle which prevents the locking
bolts from being installed along one side. The two unused locking bolt holes
should be plugged by screwing in the rubber plugs provided before installing. All
four mounting bolts MUST be tightened and the remaining two locking bolts
MUST be used.

Installation and Maintenance IAQBOX - Indoor Air Quality Box
3.0 Maintenance
Appropriate PPE (Personal Protective Equipment) should be worn during
maintenance. Precautions may also be needed to protect the surrounding area
from excess carbon residue.
To ensure the carbon filter maintains its high reduction of NO2the filter must be
replaced once the end of its lifespan has been reached. The lifespan of the carbon
filter in normal circumstances is shown in the table below.
Unit Code Carbon Filter
Lifespan
Carbon Filter
Weight (kg)
IAQBOX-S 2 years 6
IAQBOX-D 4 years 11
The carbon filter block is supported by a retaining clamp, loosening
the clamp will result in the filter being freed. Be prepared to support the
whole weight of the carbon filter block.
IMPORTANT
Replacing Single Carbon Filter - IAQBOX-S
•Unscrew the fixings securing the lid in place and remove lid from unit (see
fig. 6).
•Whilst supporting the back of the carbon filter block, loosen the retaining
clamp bolt and rotate the clamp in order to release the block (see fig. 7).
•Pulling firmly on the rear edge of the carbon filter block will lever the filter
to approximately a 45° angle (A). At this position it can be removed from
the unit (B) (see fig. 8).
•Replace the carbon filter in the reverse operation to the above process.
Ensure the filter is worked into position, the clamp rotated back and clamp
bolt tightened prior to removing support from the replacement carbon
filter block.
•Refit the unit lid.
•Wash hands thoroughly after handling.
3.1 Replacing Double Carbon Filter - IAQBOX-D
•Unscrew the fixings securing the lid in place and remove lid from unit (see
fig. 9).
•Whilst supporting the back of the carbon filter block, loosen the retaining
clamp bolt and rotate the clamp in order to release the block (see fig. 10).
•Pulling firmly on the rear edge of the carbon filter block will lever the filter
to approximately a 45° angle (A). At this position it can be removed from
the unit (B) (see fig. 11).
•Replace the carbon filter in the reverse operation to the above process.
Ensure the filter is worked into position, the clamp rotated back and clamp
bolt tightened prior to removing support from the replacement carbon
filter block.
•Refit the unit lid.
•Wash hands thoroughly after handling.

Installation and Maintenance IAQBOX - Indoor Air Quality Box
3.2 Replacing Air Filter (If Applicable)
To ensure effective particulate filtration and low system resistance, optional air
filters must be replaced every 12 months. Replacement filters are available for
purchase direct from Nuaire, with the relevant part codes shown in section 3.3
of this document.
•Unscrew the fixings securing the lid in place and remove lid from unit.
•Rotate the strap through 90° to allow removal of the filter, the fixing screw
may need to be loosened to allow strap to rotate (see fig. 12 & 13).
•Fit the replacement filter ensuring the airflow direction matches the air
flow of the unit (if applicable).
•Rotate strap back into position and refit unit lid.
