Delivery Of Equipment; Erection And Assembly - NuAire XBOXER XBC Series Installation, Operating And Maintenance Instructions

XBOXER XBC ECOSMART ADAPT (TREND) CONTROL (AT)
IMPORTANT
Safety first! – Before commencing any work ensure:
• That all appropriate risk assessments have been carried out and the
required safety measures have been taken.
• That you understand the work required.
• That you are trained and competent to carry it out.

11.0 Delivery of Equipment

11.1 Receipt of equipment
All equipment is inspected prior to despatch and leaves the factory in
good condition. Upon receipt of the equipment an inspection should be
made and any damage indicated on the delivery note.
Particulars of damage and/or incomplete delivery should be endorsed
by the driver delivering the goods before offloading by the purchaser.
No responsibility will be accepted for damage sustained during the
offloading from the vehicle or on the site thereafter.
All claims for damage and/or incomplete delivery must be reported to
Nuaire within two days of receipt of the equipment.
11.2 Offloading and Handling from the delivery Vehicle
The weight of the unit modules and palletised items is displayed on
the unit rating plate or on the packaging. Some of the modules have
an 'uneven' weight distribution, and this will be indicated by labelling
where appropriate. Ensure that lifting and handling equipment is
adequately rated. Offloading and positioning of the equipment is the
responsibility of the purchaser.
Spreaders should be used when lifting with slings to avoid damage
to the casings. Care must be taken to ensure that slings are correctly
positioned to avoid crushing and twisting of the unit castings.
Where channels and/or support frames are bolted to the underside of
the unit casing, slings or fork-lift arms should be positioned to locate in
the apertures in the channels. If Lifting Eyes have been supplied / fitted
it is recommended that they are used.
CAUTION: The XBC75 & 85 fan units have an uneven weight
distribution, please refer to the unit labelling before Lifting /
offloading the unit.

Palletised.
Slings via spreaders fitted to unit with base frame.
XBOXER XBC unit sections will be delivered to site in one section.
The unit will be labelled with the direction of air flow.
The direction convention must be observed during assembly.
The unit may only be operated in its intended horizontal
installation plane.
The unit must be fully levelled during installation (this is essential to
ensure that condensate drains correctly).
See page 6 and 13 for dimensions and weights.
11.3 Storage
The equipment must be stored in a dry, internal location. Ductwork
connection apertures shall be sealed against the ingress of dust, water
and vermin.
If the storage period is to exceed two months, contact Nuaire for
guidance on the appropriate "mothballing" procedures. Do not stack
units, modules or components.

12.0 Erection and Assembly

Units must be installed in accordance with good industry practice.
These units may only be mounted horizontally and must be fully
levelled in the horizontal plane.
The units are heavy, and should be mounted using suitable methods
of support. The supporting structure must be assessed for structural
suitability.
If these units are being fitted into a ceiling void a suitable support
structure must be provided under each unit, the baseframe provided is
'NOT' suitable for this purpose.
Heat recovery components and modules that incorporate cooling
coils may produce condensation during use. An insulated drip tray and
condensate pump is provided. The drain connection must be connected
to a suitable drainage point (see fig. 9. and 18 on page 8 and 15 for
details).
12.1 Condensate Pump Alarm
The condensate pump incorporates an alarm function. If the water
level in the condensate tray exceeds a maximum level (for example, as
a result of the discharge tube becoming blocked or frozen), the alarm
contact will open. This contact is internally connected to the heat
exchanger bypass actuator, and the unit will automatically be placed
into bypass mode, preventing further condensate production. Unit
operation will otherwise be unaffected.
Condensate pump specification
Maximum flow rate = 12 l/h
Maximum head = 20m Vertical, 100m Horizontal
Pipe Connection size (Condensate) XBOXER XBC = 8 mm
LPHW Coils, if fitted, are tested during manufacture to 16 Bar (using
dry compressed air). Coil and valve assemblies are similarly tested to 10
Bar. Operation of standard equipment is rated at PN6, if the intended
system requires higher operating pressures; please contact the Nuaire
Technical department for advice.
Electrical connections to the unit shall be made in accordance with the
appropriate product (see below); and installation wiring diagrams, and
shall use appropriately sized and rated cables.
Only the prepared apertures in the unit casing may be used for cable
entry. Do not drill or cut the unit casing for this purpose. Cable access
points are provided at the ends of the control enclosure.
If the control is rotated to aid connection of cables, please ensure that
sufficient flexibility is provided in the final connection run.
N.B. to avoid conflict with the unit access panels, it is
recommended that electrical and plumbing service connections to
the unit are run at 90 degrees to the main air flow axis.
Control circuit connections must be segregated (i.e. routed separately)
from power connections.
The unit rating label shows the maximum electrical load of the
equipment. Connections to the unit may include single phase supply
connections, and a variety of control circuits.
Only the prepared apertures in the unit casing may be used for cable
entry. Do not drill or cut the unit casing for this purpose.
The equipment must be earthed and earth-bonded. Means of local
isolation for maintenance purposes are generally required (by others).
Ensure that all mains connections are isolated.
