1.0 Important notes to installers
The successful operation of the unit depends entirely upon
installation and ongoing maintenance being carried out strictly
in accordance with these instructions.
Please read this guide in its entirety before installation and then
repeat the exercise step by set to ensure satisfactory completion.
Suitably qualified persons may achieve installation of the unit,
however the provision of the electrical supply and the connection of
the unit to the mains supply should only be carried out by a qualified
electrician.
The unit can be installed in a home with a “cold roof” construction.
These instructions are limited to installation in a home with a
“cold roof”. “Warm roofs” vary considerably and advice should
be sought from Nuaire on an individual basis.
2.0 General description
The unit is a unique Low Energy Positive Input Ventilation (LEPIV)
unit. Unlike conventional LEPIV units which only draw in external
air via the loft in a “cold roof’, the unit is capable of drawing in
external air from different roof locations via three air inlet spigots
each fitted with their own low energy open/close damper. (See fig. 1).
The units airflow and the opening/closing of each air inlet damper
is controlled via an integral intelligent control system that measures,
and appropriately responds to, temperatures at the various air inlet
locations, the home itself, the “target temperature” selected by the
occupants on the user control panel provided and the delivered air
temperature into the home.
There are two standard versions of the unit
available. Each is coded/identified as follows:
DRI-ECOSMART/1
Unit supplied with control panel providing
On/Off/Auto/Boost/Target Temperature
selection and Unit/Filter Status Indication.
DRI-ECOSMART/2
Unit supplied with control panel providing
Target Temperature selection and Unit/Filter
Status Indication.
