Models
ESTCP & ESXCP
ESTCP-R and ESXCP-R are supplied with rigid circular inlet
spigot and two opposed side discharge spigots, suited to
external roof mounted applications.

Casings are manufactured from heavy gauge 'Aluzinc'
aluminium and zinc coated mild steel. Full size access panels
are fitted to the top of the units. These panels are fully
detachable for inspection and connection purposes. The units
incorporate two independent motors with high efficiency,
centrifugal impellers running in metal scrolls.
The motors are manufactured to BS 5000 and are suitable
for single phase supply. Airflow and failure monitors are
-
standard as is Class B insulation. The units are suitable for
70
operation in ambient temperatures up to 40
133
Handling
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
The installation must be carried out by competent
personnel in accordance with the appropriate authority
and conforming to all statutory and governing regulations.
The 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
-
70
removal of fan and motor assemblies etc.
70
Whether internally or externally mounted, the method of
133
fixing is the responsibility of the installer.
133
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.
All units have an internal connection box requiring connection
to the mains supply on installation. It is the installers
responsibility to drill the case to provide access for the
electrical cables. Care should be taken not to damage internal
components and the cable entry should be properly sealed.
