Access covers on both sides of the fan unit. Access covers on both sides of the fan unit. Control cover. In this product range, several unique concepts have been implemented with a view to simplifying the installation design. 1. The unit must be installed with at least 650mm clearance from a wall / barrier. With this absolute minimum clearance, the unit may be connected to the power supply and control connection. 1000mm clearance is required to remove the HW coil and electric heater. 2. With this clearance, unit filters may be changed, and the fans coils, heat exchanger and condensate tray may be inspected and cleaned if necessary. 3. The HW and lectrical heater settings, coil bleed and drain, and all other control adjustments are similarly accessible. 4. Side access, where possible, is preferred in all cases in terms of safe working access to the equipment under the CDM regulations. 5. ote however, that access in the situation is difficult and additional time should be allocated. For convenience it is preferred that wherever possible, this minimum access provision is not adopted, and it is recommended that a minimum of around 600mm clearance (as stated in ADF 2010) is allowed. 6. Where these arrangements are not suitable, the Consultant s and Contractor s project specific requirements will always be accommodated where possible. Figure 3.

That you understand the work required. That you are trained and competent to carry it out Delivery of quipment 11.1 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. articulars of damage and/or incomplete delivery should be endorsed by the driver delivering the goods before offloading by the purchaser. o 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 uaire within two days of receipt of the equipment Offloading and Handling from the delivery Vehicle 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. nsure 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. Where channels and/or support frames are bolted to the underside of the unit casing, slings or fork-lift arms should be positioned to locate in the apertures in the channels. If ifting yes have been supplied / fitted it is recommended that they are used. CAUTIO: The XBC75 & 85 fan units have an uneven weight distribution, please refer to the unit labelling before ifting / offloading the unit. Figure 13. ifting alletised. Slings via spreaders fitted to unit with base frame. XBOXR XBC unit sections will be delivered to site in one section. The unit will be labelled with the direction of air flow. The direction convention must be observed during assembly. The unit may only be operated in its intended horizontal installation plane. The unit must be fully levelled during installation (this is essential to ensure that condensate drains correctly). See page 6 and 13 for dimensions and weights Storage The equipment must be stored in a dry, internal location. Ductwork connection apertures shall be sealed against the ingress of dust, water and vermin. If the storage period is to exceed two months, contact uaire for guidance on the appropriate mothballing procedures. Do not stack units, modules or components rection and Assembly Units must be installed in accordance with good industry practice. These units may only be mounted horizontally and must be fully levelled in the horizontal plane. The units are heavy, and should be mounted using suitable methods of support. The supporting structure must be assessed for structural suitability. If these units are being fitted into a ceiling void a suitable support structure must be provided under each unit, the baseframe provided is OT suitable for this purpose. Heat recovery components and modules that incorporate cooling coils may produce condensation during use. An insulated drip tray and condensate pump is provided. The drain connection must be connected to a suitable drainage point (see fig. 9. and 18 on page 8 and 15 for details) Condensate ump Alarm The condensate pump incorporates an alarm function. If the water level in the condensate tray exceeds a maximum level (for example, as a result of the discharge tube becoming blocked or frozen), the alarm contact will open. This contact is internally connected to the heat exchanger bypass actuator, and the unit will automatically be placed into bypass mode, preventing further condensate production. Unit operation will otherwise be unaffected. Condensate pump specification Maximum flow rate = 12 l/h Maximum head = 20m Vertical, 100m Horizontal ipe Connection size (Condensate) XBOXR XBC = 8 mm HW Coils, if fitted, are tested during manufacture to 16 Bar (using dry compressed air). Coil and valve assemblies are similarly tested to 10 Bar. Operation of standard equipment is rated at 6, if the intended system requires higher operating pressures; please contact the uaire Technical department for advice. lectrical connections to the unit shall be made in accordance with the appropriate product (see below); and installation wiring diagrams, and shall use appropriately sized and rated cables. Only the prepared apertures in the unit casing may be used for cable entry. Do not drill or cut the unit casing for this purpose. Cable access points are provided at the ends of the control enclosure. If the control is rotated to aid connection of cables, please ensure that sufficient flexibility is provided in the final connection run..b. to avoid conflict with the unit access panels, it is recommended that electrical and plumbing service connections to the unit are run at 90 degrees to the main air flow axis. Control circuit connections must be segregated (i.e. routed separately) from power connections. The unit rating label shows the maximum electrical load of the equipment. Connections to the unit may include single phase supply connections, and a variety of control circuits. Only the prepared apertures in the unit casing may be used for cable entry. Do not drill or cut the unit casing for this purpose. The equipment must be earthed and earth-bonded. Means of local isolation for maintenance purposes are generally required (by others). nsure that all mains connections are isolated. nuaire.co.uk eaflet umber

15 13.0 Commissioning and Setting To Work (ote not all of the components listed here are necessarily included with the equipment supplied) Filters Remove filter access panels (observe and note airflow direction labels), inspect filters for contamination with construction debris, replace as necessary. Replace access panels. Filter pressure drops will depend on actual flow rate and condition. Observe and record filter pressure drops after performance commissioning. Typically, filter dirty condition occurs when the initial filter clean readings have been increased by 125a. If filter manometers, pressure switches or indicators have been fitted, they should be set or adjusted to reflect the commissioned system operation Heating Coils HW Observe the Flow and Return connection labels on the unit. Drain and bleed valves are located on the coil (see fig 19). Other valves may be required in the system pipe-work depending on the installation (by others). Where the wet system is at risk of frost damage, the addition of a proprietary anti-freeze solution to the water is recommended. ote that any frost protection offered by the unit s integral control system will not operate if the power supply to the unit is interrupted. cosmart frost protection is activated on any cosmart unit fitted with HW heating, when the outlet air temperature is 4ºC or below. The unit reacts by shutting down the fan to prevent a wind chill effect reducing the temperature to a point whereby the coil could freeze and burst. The unit will also drive open the HW valve to a fully open position to allow full water flow through the coil and the main CB will close the Heat demand contacts. These contacts could be used to send a signal to activate the boiler and/or valve to open to provide heat if not already doing so. iped connections should be made to the unit using appropriate techniques, and all pipework must be independently supported. o hot work is permitted within one metre of the unit. nsure that installed pipework runs do not prevent or restrict access to the unit at any point. The completed installation (including the connections within the unit, as these may be disturbed during installation) shall be pressure tested to the project engineer s specification (This is a condition of the unit warranty) lectric Heaters Heater Capacity: XBC75 3ph, 12Kw XBC85 3ph, 18Kw The lectric Heater requires a 3ph supply which is independent from the main unit supply. Connections to be made through the low level fixed panel. The lectric Heater may be withdrawn to allow access to the Heater Controller without the need for wiring to be disconnected (nsure the mains supply is isolated before removing any access panels and any adjustments are made to the Heater Controller) Fan Sections Access to the fan section is via lift off panels (see fig. 1 & 19). For non-cosmart units, wiring to the fan motor / unit terminal box should be mechanically protected and in made in accordance with the details on the motor name plate and diagram attached to the unit. With the unit electrically isolated, rotate the fan impeller / drive manually, checking that it spins freely. Check all fixings are secure. Units must not be operated without all access panels in place damage to equipment or injury to personnel may result. Units must not be operated unless control interlocks are in place damage to equipment may result. Test run motor for condition and correct rotation. Check that the correct current overloads are fitted and that the current being drawn does not exceed the motor nameplate value. xcessive current normally indicates that the ductwork system resistance is different to design.

This set up is suitable for the majority of applications. When ancillaries with high pressure losses are fitted to the inlet side of the fan, the low pressure tapping must be moved from the fan chamber to a location upstream of the ancillaries, as shown below in fig. 18. Failure to do this will result in excessive pressure being applied to the dampers at the rooms when the system is running in trickle mode. Figure 18. Constant pressure tapping.
