NuAire DRI-ECO-LINK-HC Installation And Maintenance

1.0 INTRODUCTION
The DRI-ECO-LINK-HC provides whole home ventilation using the Positive Input
Ventilation 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 the
filters and inputting it, at ceiling level, into the property.
The DRI-ECO-LINK-HC fan unit includes an internal sensor to regulate the fan
speed according to the temperature of the loft. The internal sensor is to increase
airflow to the dwelling when the loft is warmer than the house. The units 'Fixed
Temperature Heat Recovery' strategy shall be achieved via a sensor located in
the unit and shall improve energy performance accordingly. This unit has all the
controls for the fan in the ceiling vent allowing the user to control, programme
and monitor the unit from inside the property. It also has the ability to be
controlled using a RF function and can be boosted from a remote wall mounted
switch, remote CO2 detector and an RH sensor.
Once installed, the airflow can be set to suit the house size and, if required, the
way it responds to the temperature changes within.
2.0 IMPORTANT NOTES TO INSTALLERS
Successful operation of the fan depends entirely upon the unit being installed
strictly in accordance with these instructions.
Please read through this guide in its entirety before commencing installation and
follow step by step to ensure a satisfactory completion.
Whilst the installation of the DRI-ECO-LINK-HC unit may be achieved by
suitable persons, the provision of the electrical supply and the connection of the
unit to the mains must be carried out by a qualified electrician.
Warning: Isolate from power supply before removing any covers. During
installation/maintenance ensure all covers are fitted before switching on the
mains supply.
This appliance can be used by children aged from 8 years and above and persons
with reduced physical, sensory or mental capabilities or lack of experience and
knowledge if they have been given supervision or instruction concerning use of
the appliance in a safe way and understand the hazards involved. Children shall
not play with the appliance. Cleaning and user maintenance shall not be made
by children without supervision.
Precautions must be taken to avoid the back-flow of gases into the room from
the open flue of gas or other fuel-burning appliances.
Means for disconnection must be incorporated in the fixed wiring as shown in
the wiring diagram in accordance with IEE wiring or national wiring rules.
CAUTION: In order to avoid a hazard due to inadvertent resetting of the thermal
cut-out, this appliance must not be supplied through an external switching
device, such as a timer, or connected to a circuit that is regularly switched on
and off by the utility.
3.0 LOFT INSPECTION
Check to ensure that the loft has adequate ventilation. There may be occasions
where a loft is so well sealed that additional ventilation may have to be provided
by 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 be
carried out by the installer.
If any leakage points are found, or if there is any doubt at all, then the installer
should advise the house owner/provider as soon as possible and seek instruction
from them before proceeding with the installation.

4.0 DIFFUSER INSTALLATION
4.1 Siting the Diffuser Position
The diffuser has a unique air throw pattern and it is essential that it is located
correctly in the central hallway in single storey properties or in the ceiling of the
top floor landing on 2 or more storey dwellings.
The diffuser discharges air evenly from all directions along the underside of the
ceiling.

Note: SMOKE ALARMS -It is also important to ensure that the diffuser is
NOT placed within 1 metre of a smoke alarm.
If the diffuser cannot be repositioned, two sides of the diffuser must be closed
off using the air dams supplied to encourage the air through the remaining open
sides that faces at least 1.5 metres of unobstructed area away from the smoke
alarm sensor.
4.2 Fitting the Air Dams
Air dams are provided to alter the direction of airflow and should be fitted as
needed. 2 air dams are supplied and will fit on any of the diffuser sides to guide
airflow away from a smoke detector and/or obstructions.

4.3 Fitting the Ceiling Diffuser
To install the diffuser, use the tear-out template from the lid of the unit
packaging 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 should
be positioned for ease of access (i.e. NOT facing over a stairwell). Once the
shape has been cut out, position the ceiling and secure it in place using the 4
screws and plugs provided. After fitting, the fan unit must be connected to the
diffuser using the loom provided. The connectors are located on the rear of the
ceiling vent and the rear recess of the fan unit.
Finally attach the diffuser cap to the frame using the four built-in press on clips
provided.
