NuAire DRI-ECO-HEAT-HCS Installation, Maintenance And Operation

1.0 INTRODUCTION
The DRI-ECO-HEAT-HCS provides whole home ventilation using
the Positive Input Ventilation principle. The concept is to introduce
fresh, filtered air into the dwelling 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-HEAT-HCS 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. A heater section
incorporating a 400W heating element shall be fitted to the fan unit.
It shall be electronically controlled so as to minimise energy use. A
temperature sensor shall be fitted to the outlet of the heater and will
control the output of the heater in an attempt to maintain the set
point. The set point will be adjustable between 5˚C and 15˚C.
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-HEAT-HCS 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.

Installation, Maintenance and Operation
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.
Check any flues or chimneys for leakage in the loft via a visual
•
inspection, 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 in 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 (If Required)
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.
