Leaflet Number 671756nuaire.co.uk 029 2085 8400DRI-ECO-LINK-HCWhole House Ventilation Unit with Hall ControlInstallation and Maintenance The EMC Directive2014/30/EUThe Low VoltageDirective2014/35/EU1.0 INTRODUCTIONThe DRI-ECO-LINK-HC provides whole home ventilation using the Positive InputVentilation principle. The concept is to introduce fresh, filtered air into the dwell-ing at a continuous rate, encouraging movement of air from inside to outside.To achieve this the unit is mounted in the loft space, drawing air through thefilters and inputting it, at ceiling level, into the property.The DRI-ECO-LINK-HC fan unit includes an internal sensor to regulate the fanspeed according to the temperature of the loft. The internal sensor is to increaseairflow to the dwelling when the loft is warmer than the house. The units ‘FixedTemperature Heat Recovery’ strategy shall be achieved via a sensor located inthe unit and shall improve energy performance accordingly. This unit has all thecontrols for the fan in the ceiling vent allowing the user to control, programmeand monitor the unit from inside the property. It also has the ability to becontrolled using a RF function and can be boosted from a remote wall mountedswitch, remote CO2 detector and an RH sensor.Once installed, the airflow can be set to suit the house size and, if required, theway it responds to the temperature changes within.3.0 LOFT INSPECTIONCheck to ensure that the loft has adequate ventilation. There may be occasionswhere a loft is so well sealed that additional ventilation may have to be providedby the owner/occupier.Ensure that all water tanks are covered and sealed.Check that all water pipes are lagged.Ensure that any extract fans are discharging to outside and not into the loft.Check that the loft hatch is tightly sealed.Ensure that all holes in the ceilings are sealed i.e. ceiling light fittings etc.A visual inspection of any flues or chimneys for leakage in the loft should becarried out by the installer.If any leakage points are found, or if there is any doubt at all, then the installershould advise the house owner/provider as soon as possible and seek instructionfrom them before proceeding with the installation.4.0 DIFFUSER INSTALLATION4.1 Siting the Diffuser PositionThe diffuser has a unique air throw pattern and it is essential that it is locatedcorrectly in the central hallway in single storey properties or in the ceiling of thetop floor landing on 2 or more storey dwellings.The diffuser discharges air evenly from all directions along the underside of theceiling.Speed Setting Minimum distance of diffuser from wall1 100mm2 155mm3 400mm4 625mm5 850mm6 1000mmNote: SMOKE ALARMS -It is also important to ensure that the diffuser isNOT placed within 1 metre of a smoke alarm.If the diffuser cannot be repositioned, two sides of the diffuser must be closedoff using the air dams supplied to encourage the air through the remaining opensides that faces at least 1.5 metres of unobstructed area away from the smokealarm sensor.4.2 Fitting the Air DamsAir dams are provided to alter the direction of airflow and should be fitted asneeded. 2 air dams are supplied and will fit on any of the diffuser sides to guideairflow away from a smoke detector and/or obstructions.1Ceiling VentAir DamDiffuser Cap2.0 IMPORTANT NOTES TO INSTALLERSSuccessful operation of the fan depends entirely upon the unit being installedstrictly in accordance with these instructions.Please read through this guide in its entirety before commencing installation andfollow step by step to ensure a satisfactory completion.Whilst the installation of the DRI-ECO-LINK-HC unit may be achieved bysuitable persons, the provision of the electrical supply and the connection of theunit to the mains must be carried out by a qualified electrician.Warning: Isolate from power supply before removing any covers. Duringinstallation/maintenance ensure all covers are fitted before switching on themains supply.This appliance can be used by children aged from 8 years and above and personswith reduced physical, sensory or mental capabilities or lack of experience andknowledge if they have been given supervision or instruction concerning use ofthe appliance in a safe way and understand the hazards involved. Children shallnot play with the appliance. Cleaning and user maintenance shall not be madeby children without supervision.Precautions must be taken to avoid the back-flow of gases into the room fromthe open flue of gas or other fuel-burning appliances.Means for disconnection must be incorporated in the fixed wiring as shown inthe wiring diagram in accordance with IEE wiring or national wiring rules.CAUTION: In order to avoid a hazard due to inadvertent resetting of the thermalcut-out, this appliance must not be supplied through an external switchingdevice, such as a timer, or connected to a circuit that is regularly switched onand off by the utility.4.3 Fitting the Ceiling DiffuserTo install the diffuser, use the tear-out template from the lid of the unitpackaging and trace the shape onto the ceiling between two convenient joists.The shape is elliptical to allow space for the PCB of the controls and this shouldbe positioned for ease of access (i.e. NOT facing over a stairwell). Once theshape has been cut out, position the ceiling and secure it in place using the 4screws and plugs provided. After fitting, the fan unit must be connected to thediffuser using the loom provided. The connectors are located on the rear of theceiling vent and the rear recess of the fan unit.Finally attach the diffuser cap to the frame using the four built-in press on clipsprovided.
