Nuaire | Western Industrial Estate | Caerphilly | CF83 1NA | nuaire.co.uk XBC75 & 85 (AS Control) Installation Manual 5.0 ACCESS CONCEPTS In this product range, several unique concepts have been implemented with a view to simplifying the installation design. Isolate before removing any panels •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 LPHW coil and electric heater. •With this clearance, unit filters may be changed, and the fans coils, heat exchanger and condensate tray may be inspected and cleaned if necessary. •The LPHW and Electrical heater settings, coil bleed and drain, and all other control adjustments are similarly accessible. •Side access, where possible, is preferred in all cases in terms of safe working access to the equipment under the CDM regulations. •Note 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. •Where these arrangements are not suitable, the Consultant’s and Contractor’s project specific requirements will always be accommodated where possible. 5.1 Horizontal Units (e.g. XBC75-H, XBC85-H) 6 Horizontal Unit Access Access covers on both sides of the fan unit Control cover 7 Horizontal Unit Overview With Lid Removed Showing Air Paths Intake Extract from room Exhaust Supply to room G4 Filter Counterflow Heat Exchanger 8mm outside dia. condensate drain.

Condensate pump fitted as standard with alarm facility. 6.0 MECHANICAL INSTALLATION 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 unit will be labelled with the direction of air flow. The direction convention must be observed during installation. 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). 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 base frame provided is NOT suitable for this purpose. LPHW 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 PN6, if the intended system requires higher operating pressures; please contact the Nuaire Technical department for advice. Electrical connections to the unit shall be made in accordance with the appropriate product; 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.

Nuaire | Western Industrial Estate | Caerphilly | CF83 1NA | nuaire.co.uk XBC75 & 85 (AS Control) Installation Manual If the control is rotated to aid connection of cables, please ensure that sufficient flexibility is provided in the final connection run. 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). Ensure that all mains connections are isolated. 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 (Figures 10 & 11). 6.1 Condensate Pump 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. Maximum flow rate = 12 l/h Maximum head = 20m Vertical, 100m Horizontal Pipe Connection size (Condensate) XBOXER XBC = 8 mm 6.2 Pre-Commissioning Not all of the components listed here are necessarily included with the equipment supplied. 10 Customer Connections (Control Side of Horizontal Unit) LPHW or electric heater supply connections Control box Access to condensate tray and pump Condensate drain connection Ø 8mm push-fit 6.2.1 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 125Pa. If filter manometers, pressure switches or indicators have been fitted, they should be set or adjusted to reflect the commissioned system operation. 11 Customer Connections (Control Side of Vertical Unit) LPHW or electric heater supply connections Control box Access to condensate tray and pump Condensate drain connection Ø 8mm push-fit Fixed panel for customer connections 6.2.2 Heating Coils LPHW Observe the Flow and Return connection labels on the unit. Drain and bleed valves are located on the coil. 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. Note that any frost protection offered by the unit’s integral control system will not operate if the power supply to the unit is interrupted. Ecosmart frost protection is activated on any Ecosmart unit fitted with LPHW 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 LPHW valve to a fully open position to allow full water flow through the coil and the main PCB 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. Piped connections should be made to the unit using appropriate techniques, and all pipework must be independently supported. No hot work is permitted within one metre of the unit. Ensure 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). 6.2.3 Electric Heaters Heater Capacity: XBC75 – 3ph, 12Kw XBC85 – 3ph, 18Kw The Electric Heater requires a 3ph supply which is independent from the main unit supply. Connections to be made through the low level fixed panel. The Electric Heater may be withdrawn to allow access to the Heater Controller without the need for wiring to be disconnected (Ensure the mains supply is isolated before removing any access panels and any adjustments are made to the Heater Controller).

Nuaire | Western Industrial Estate | Caerphilly | CF83 1NA | nuaire.co.uk XBC75 & 85 (AS Control) Installation Manual 6.2.4 Fan Sections Access to the fan section is via lift off panels. For non-Ecosmart 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. Excessive current normally indicates that the ductwork system resistance is different to design. 6.2.5 Motorised Dampers If Nuaire matched silencers (Horizontal: XBC75-H-SIL900, Vertical: XBC75-V-SIL900) are being fitted to the fan unit, the motorised damper (Horizontal: XBC75-H-MD24V, Vertical: XBC75-V-MD24V ) needs to be fitted after the silencer. This ensures that breakout noise levels are kept to a minimum. •Fully interlocking parallel blades, half inch diameter electroplated mild steel spindle. •Nylatron bushes and external nylon/aluminium blade interconnection linkage. •Fitted with drive open/drive close actuator complete with switch. •Motorised damper wiring will require connection on site and possible extension of the cable looms.

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 Figure 13. 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. 13 Typical Constant Pressure Setup Riser Ancillaries Riser Inlet e.g. Silencer Pressure Balancing Branch Damper Balancing Branch Damper Extract Fan To atmosphere Sensor High Low Pressure Flexible tubing New Pressure Tapping Airflow

Nuaire | Western Industrial Estate | Caerphilly | CF83 1NA | nuaire.co.uk XBC75 & 85 (AS Control) Installation Manual 6.4 Filter Pressure Switch XBC 75 & 85 units come with pre fitted pressure tappings and tubing for use with the fitted dirty filter alarms on both the supply and extract air streams. The IP54 pressure switch is equipped with a red visual LED alarm which will illuminate when the pressure reading surpasses that set by the adjustable knob. 6.4.1 Setting Switch Pressure Make certain that there is no voltage on the electrical connections before you carry out any setting on the pressure switch, there is the possibility of an electric shock if you accidentally touch live parts. 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. 6.4.2 Switch Wiring The cable gland is designed for cables with alternative sheath diameters of 7 mm or 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 14) ensuring the feed line is fused to suit Max 1.5A / 250 Vac.

This diagram only shows the essential field wiring points for clarity. 8.1 LPHW Frost Coils 8.1.1 Wiring The heater requires a 230V~50Hz single phase supply connection to power the thermostat and valve actuator. Remove the top cover from the terminal box by rotating the four fixing screws half a turn, revealing the terminal block marked LEN. 29 Wiring - LPHW Frost Coil Ancillary 230VAC Fused Supply 8.1.2 Setting 'Frost Condition' Temperature The LPHW heater frost coil is only enabled if the frost stat reads a ‘frost condition’. A ‘frost condition’ temperature adjustment dial is provided as part of the frost coil controls. The ‘frost condition’ temperature is easily adjustable from -10 to +10°C by inserting a small screwdriver into the adjuster aperture and rotating the spindle clockwise or anticlockwise. It is recommended that the ‘frost condition’ temperature is set at 4°C. 8.2 Electric Frost Coils 8.2.1 Wiring The heater requires two connections; the relay link up and the 400V~50Hz three phase supply connection to power the heater element. Remove the top cover from the terminal box by rotating the four fixing screws half a turn, revealing the terminal block. The relay connection between main controls and the frost coil module can now be made. 8.2.2 Setting 'Frost Condition' Temperature The electric heater frost coil is only enabled if the frost stat reads a ‘frost condition’, the over-temperature cut-out is healthy AND a 24vac fan run signal is received from the main control panel. A ‘frost condition’ temperature adjustment dial is provided as part of the frost coil controls. The ‘frost condition’ temperature is easily adjustable from -10 to +10°C by inserting a small screwdriver into the adjuster aperture and rotating the spindle clockwise or anticlockwise. Once enabled the electric heater frost coil will provide its maximum heat output to achieve the ‘frost condition’ temperature set by the frost stat. It is recommended that the ‘frost condition’ temperature is set at 4°C. 32 Wiring - Electric Frost Coil Ancillary

Nuaire | Western Industrial Estate | Caerphilly | CF83 1NA | nuaire.co.uk XBC75 & 85 (AS Control) Installation Manual 9.0 CONTROLS 30 Controller 9.1 Controllable Items •Inlet damper (if fitted). •Extract damper (if fitted). •Heat recovery & bypass damper. •Heating coil. •Supply fan speed. •Extract fan speed. 9.2 Enable Signal The unit can be enabled via the following methods: •Software switch via strategy. •Switched live (230VAC) input, PIR etc. via digital input. •Low voltage contacts via digital input. •Night cooling / summer free-cooling strategy. When the enable signal is removed, the unit will run on for a time defined by the run-on setpoint. If an electric heater is fitted, the fans will automatically run-on for an extra 2 minutes, without heating, in order to dissipate residual heat. 9.3 Occupancy Control When a Trend occupancy sensor is selected via UI4 & 5 software module, the control will look for a Trend OCC-U sensor in the appropriate input. An occupied signal will give an enable signal. •0V = Occupied •14V = Unoccupied 9.4 Boost Speed When the control receives a boost signal the fans will run at boost speed. Once the signal is removed the fans will run on for a time defined by the boost run-on setpoint. 9.5 Trickle Speed When trickle mode is active, the fans will run at their minimum speed even when there is no enable signal. Heating and cooling will also function in this mode if available. 9.6 CO2 Control When a CO2 sensor is connected, CO2 control is enabled via the CO2 software switch and an enable signal is received, ventilation will increase to reduce CO2 concentration the target CO2 setpoint. The target CO2 sensor setpoint can be changed as one of the commissioning setpoints. 9.7 Supply Temperature Control While an enable signal is present, this mode modulates heating, cooling & heat exchanger bypass dampers with the aim of the supply air reaching the temperature setpoint. Please note that heating and cooling outputs will only function if the HeatingType or CoolingType setpoints are set to heating or cooling options. 9.8 Frost Protection Should the internal temperature of the unit fall below a value defined in the commissioning variables, the control will override all heating/ cooling logic to open the LPHW or CW control valves, if fitted. This is to allow any protective flow through the heating/cooling coils. The supply fan will also stop and the appropriate frost protection software module will enter an alarm state. This period will last for a minimum of 5 minutes by default. The fault relay will also open. Please note that frost protection will only function if the HeatingType or CoolingType switches are set to LPHW or CW. 9.9 Night Cooling / Summer Free Cooling Once enabled in software, this routine uses an individual time schedule to cool the fabric of the building at night using only the external air. This mode only functions if the daytime temperature is above the setpoint, cooling is possible and if the cooling air is not too cold. 9.10 Alarms 9.10.1 Critical Alarm (Latching) Once in critical alarm state the unit will drive all heating and cooling outputs to 0V. Other functions continue as normal. The critical alarm is latched and required manual reset to clear. Causes of critical alarm: •Fan fail via alarm circuit 1. •Heater overtemp via alarm circuit 1. 9.10.2 Maintenance Alarms (Non-Latching) Once in maintenance alarm state the only action taken is de-energising of the fault relay. Once the trigger is removed, the alarm will reset automatically. Causes of maintenance alarm: •Sensor failure •Low supply temperature, default 8°C. •Frost protection routine active, default 4°C (Only runs if water valves are selected as fitted). •Excessively high supply temperature reading (Will stop heating). •Filter fault All alarms have a hold off period set by the setpoint “Alarm delay”. 9.10.3 Thermal Trip In case of software failure, as a final resort, the electric heater is protected by a fail-safe thermal overload switch. This switch disables the heater controller via a contactor once the temperature reaches 80°C. When this occurs, the critical alarm will latch in software. Once the unit cools, the contactor will re-engage but the heater signal will remain at 0V until the critical fault is reset in software or by power cycle.
