NuAire FLAT2000L Installation And Maintenance Manual

1.0 INTRODUCTION

The Nuaire Drimaster/Flatmaster range has been curing severe
condensation problems for over 20 years in some of the worst affected
properties throughout the world. Its successful operation depends
entirely upon the unit being installed strictly in accordance with these
instructions. We would, therefore, respectfully suggest that you read
through this guide in its entirety before commencing installation
and then go through this guide step by step to ensure a satisfactory
completion.
Units are supplied assembled and include a thermostatically controlled
heater. A unit mounted override switch is provided. A 'BOOST' speed
facility for additional ventilation is included, this is operated by a
remote switch (supplied).
The FLAT2000 L/R is a 'handed' product, with the L/R signifying the
discharge direction, as viewed from the front. The FLAT2000L unit is
supplied arranged for LEFT HAND discharge of air. The FLAT2000R unit
is supplied arranged for RIGHT HAND discharge of air.
IMPORTANT
Whilst the installation of the Flatmaster unit may be achieved
by a suitable craftsman, the provision of the electrical supply and
the connection of the unit to the mains must be carried out by a
qualified electrician.
2.0 INSTALLATION
IMPORTANT
Where the systems are installed in flats, ensure all regulatory
provisions are adhered to. Where the systems are installed in flats
where these regulatory provisions do not apply, good installation
practice should be observed.
For more information please refer to the Building Regulations,
Approved Document B (Fire safety) – Volume 1: Dwelling houses
(2006 Edition).
The unit is designed to take fresh air from outside, clean the air, and
discharge it into the central hallway via a system of ducting supplied by
the installer.
The dwelling supply grille is usually installed at high level in a central
location within the hallway, although discharging the air down the
length of the hallway (away from the front door) should also prove
acceptable. Unit performance may be enhanced if an existing heat
source can warm the discharged air e.g. by locating the discharge grille
above a radiator.
Before commencing installation decide the best position for the unit
and where the fresh air is to come from and be discharged to. The unit
can be installed in many different configurations and is supplied with
enough interchangeable spigots to enable it to be used with either
circular (100mm) or rectangular ducting (121mm x 60mm).
IMPORTANT
The heater outlet MUST NOT be left exposed. A minimum
distance of 500mm is required between the discharge grille and the

2.1 Spigot Inserts

The unit is designed to be used with rigid ducting only. Ensure that
when the ducting is fitted it is secured in place using wall brackets and
screws on the duct as close to the spigots as possible to prevent the
spigot inserts (fig 1) or rigid ducting from being removed or accidentally
knocked off. If it is necessary to fit flexible ducting then the spigot
inserts should be glued in place, using super glue Loctite 454 Gel, at the
clip points 1, 2, 3 & 4 for all spigot inserts (see fig. 2).

Note: If the circular spigot is used as an outlet, the 115 x 55mm clear
blanking plate will need to be fitted (as shown). This plate should be
prevented from movement by the use of silicone sealant.
