Introduction
Units are rectangular in section and consist of three basic
designs.
Full size access panels are fitted to the top of the units and
are fully detachable for inspection and connection purposes.
The models are coded as follows:
EST-X (External/Internal Duct Mounted) in line unit.
C
EST-R (Roof Mounted, end inlet) side discharge unit.
EST-B (Roof Mounted bottom inlet) side discharge unit.
EST-X units are rectangular in section and have circular rigid
spigots at each end.
EST-R units are rectangular in section and are supplied with
a circular end spigot and two opposed side discharge grilles.
EST-B units are rectangular in section and have a rectangular
bottom spigot and two opposed side discharge grilles.
Handling
Always handle the units carefully to avoid damage and
distortion. If mechanical aids are used to lift the unit, spreaders
should be employed and positioned so as to prevent the slings,
webbing etc. making contact with the casing.
Installation
Installers - please note that Installation must be carried
out by competent personnel in accordance with the
appropriate authority and conforming to all statutory and
governing regulations e.g. I.E.E, CIBSE, COHSE.
EST-X/R/B units are suitable for internal or external use.
All units can be installed at any angle up to 60
sloping roof the unit must be blowing upwards toward the
roof ridge to ensure correct backdraught shutter operation.
Units should always be positioned with sufficient space to
allow removal of the access cover and subsequent removal
of fan and motor assemblies etc.
Whether internally or externally mounted, the method of fixing
to the roof is the responsibility of the installer.
All units have a bottom skirt to allow for fixing directly onto
a suitably sized curb or builders upstand. Nuaire can supply a
matching prefabricated curb for these units. Details of curbs
and dimensions for a suitable external concrete upstand are
shown on page 2.
Ductwork connections must be airtight to prevent any loss of
performance.
In High humidity applications above 90%
trickle ventilation is recommended.
