Signifies a general warning regarding hazard specified by supplementary information.
This unit must be completely electrically isolated before any panels are removed. Check mains supply and control connections.
This unit contains fast moving rotational parts which may start automatically. It is the sole responsibility of the installer to adequately guard these components.
Read and understand the installation and maintenance manual before installing, operating or maintaining this product.
This manual contains important information on the safe and appropriate assembly, transport, commissioning, operation, maintenance, disassembly and simple troubleshooting of the product.
While the product has been manufactured according to the accepted rules of current technology, there is still a danger of personal injury or damage to equipment if the following general safety instructions and the warnings contained in these instructions are not complied with.
The following minimum Personal Protective Equipment (PPE) is recommended when interacting with Nuaire product:
Nuaire would always recommend a site specific risk assessment by a competent person to determine if any additional PPE is required.
Units are rectangular in section and have circular rigid spigots at each end. Four matching mounting feet are supplied with the unit. The unit shall be double skinned with 35mm infill panels and shall be manufactured from heavy gauge, corrosion resistant Aluzinc steel, internally lined with acoustic material. Fully detachable panels for maintenance/service and manometer test points. The fan should be with an ‘inline assembly’, positioned in series for optimum performance.
Units 1 – 6 incorporate a full size access panel fitted to the bottom face which is fully detachable for inspection purposes. The underside access panel can be slid in either direction with-out removal, if required (Section 4.7.1).
Units 7 – 9 incorporate a split access panel fitted to the bottom face which is fully detachable for inspection purposes. Each split access panel can be moved and opened individually and slid in either direction without removal, if required (Section 4.7.2).
Upon receipt of the equipment, an inspection should be made. Before commencement of lifting, ensure that normal equipment safety checks have been carried out.
A unit / module should be removed from the vehicle using a fork lift or crane. Always handle with care to avoid damage and distortion, and where lifting slings are employed use spreaders to ensure slings do not come into contact with the unit case, or control pack. Correctly position slings to avoid twisting of the unit case and observe the centre of gravity before the final lift is made. The weight of the unit is available on the unit rating plate.
Dependent on model and size, units may be supplied in single or multimodular sections. Handle each section individually do not stack for lifting or storage.
Installation must be completed by competent persons, in accordance with good industry practice and should conform to all governing and statutory bodies i.e. IEE, CIBSE, etc.
The units are supplied for installation into In-line ductwork (internal) applications only. All ductwork connections must be airtight to prevent loss of performance.
The unit has an external case side mounted control module / terminal box and is supplied ready for connection into the electrical supply. The control is mounted on the side of the unit as standard but its position can be changed to the other side of the unit if required, fixings by others (Section 4.8).
The method of mounting used is the responsibility of the installer.
The units can be mounted in any of the below attitudes enabling alternative control positions.
Once assembled, units should always be positioned with sufficient free space adjacent to the unit to allow for access panel(s) to extend forward for future inspection, maintenance, component service, repair and replacement. The access panel(s) require opening clearance to operate.
Utilising four matching anti-vibration (AV) mounting feet (Figure 1). AV mounts isolate the fan only, silencers / back draught dampers and other “significant mass” accessories should form part of the fixed ductwork after the flexible connection.
From the ceiling or in the ceiling void using four AV mounting feet supplied, with access panel positioned for underside access (Figure 2 & 3).
Utilising the Aire-Volve Vertical Hanging Bracket kit that includes wall hanging brackets and hinges (Figures 4 and 5). The unit case has captive M8 nuts which can be used after removing the M8 ‘plugging’ screws.
Units should always be positioned with sufficient space to allow the access panel to extend forward. Only suitable for units mounted indoors.

AV mounts should not be fitted to a fan/silencer assembly unless there are flexible connectors fitted between the assembly and associated duct work. AV mounts should be installed with the matched mounting feet and positioned such that they carry an equal proportion of the assembly weight. This is particularly important where fans and silencers are installed on suspension rods. Suspension rods and fixing screws are not supplied.
Resilient rubber anti-vibration mounting kits (NAV) are available, the correct selection and type employed will depend on the accurate calculation of the weight of the assembly to be supported.
The large round washers included with the NAV(2-5) are for fitting above or below the resilient mounting as required to safeguard the installation against break-up of, or damage to, a mounting. In the event of a resilient mounting failure, the washer will support the weight of the unit. Fans using size NAV 6 upwards require supporting steelwork to be designed (by others) for suspended applications.
AV mounts must only be subjected to compressional forces and MUST NOT be used in a configuration that places these parts under tension or shear force.

Matched AVT Silencers
Matched silencers with double walled Aluzinc construction and 35mm infill acoustic lining provides the best acoustic solution.
Easy fit matching silencers with simple integral brackets can be easily incorporated into existing drop rod systems helping to reduce install time on site.
|Unit Code||Silencer Code||Size||A||B||C||Weight (kg)|
To change orientation of attenuator pod just turn silencer over before fitting. Use fixing brackets as shown below. Ensure that the attenuator pods are in the correct orientation as shown in Figure 16.
Remove spigot panels from each end of the main unit and relocate them to the open silencer ends. The coupling system located on the sides of the silencers and AVT unit simply clips together with additional alignment bolts (ensure alignment bolts are correctly located).
Ensure fixing brackets halves are correctly aligned and assemble using M8 Cap head bolt and nut supplied with bracket. Once located, tighten bolts ensuring seal between silencer and seal is achieved.

Choose your required control handing prior to unit installation.
Isolation – Before commencing work, make sure that the unit and Nuaire control are electrically isolated from the mains supply.
Because the run and start currents depend upon the duty and associated ductwork of an individual unit, run currents will be exceeded if the unit is operated with its cover removed. It is therefore recommended that the unit is not run for prolonged periods in this condition.
Unit details including Full Load Current, Voltage, fan speed etc. can be found on the unit label.
The wiring illustrations below are for units without control. All wiring is terminated in junction boxes fitted to the side of the unit. Local isolator (by others)
Do not wire the power supply to motor via the motor alarm relay as terminals are only closed after the motor is energized.
The alarm relay on condensate may require the use of a contactor if the host equipment supply is switched.
The No Control (NC) units described in this manual are supplied without any controls. It is the installer’s responsibility to select and install suitable controller(s) and circuit(s) to produce the desired output from the units while remaining within the units safe performance envelope.
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.
The 2 year warranty starts from the day of delivery and includes parts and labour for the first year. The remaining period covers replacement parts only.
This warranty is void if the equipment is modified without authorisation, is incorrectly applied, misused, disassembled, or not installed, commissioned and maintained in accordance with the details contained in this manual and general good practice.
