Installation Manual
2.0 INTRODUCTION
The information contained in this document provides details of
installation, operation and maintenance for installers and users of
the XBOXER XBC75 & 85 Supply and Extract Ventilation Units with
Heat Recovery.
This supply and extract air handling unit range comprises an
combination of high efficiency centrifugal fans with EC motors, a
counterflow design plate heat exchanger, filters, optional heaters
(LPHW and Electric) and a casing with high mass acoustic treatment.
The one-piece ventilation unit shall be constructed with double
skinned Aluzinc panels on an aluminium Pentapost frame with integral
acoustic mineral fibre ensuring low breakout noise levels. The unit
shall incorporate a high efficiency aluminium counterflow plate heat
exchanger matrix with a thermal efficiency of up to 92%, fitted with
a segmented 100% bypass facility and actuator (patent app. for)
operating under automatic control.
A range of matched, side by side internal and external attenuators
(horizontal units) and double deck internal and external attenuators
(vertical units) with a similar construction method to that of the unit is
available.
General information regarding performance and specifications for the
equipment may be obtained from our Technical Literature, and / or
project specific documentation.

3.0 DELIVERY
3.1 Receiving 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.
3.2 Vehicle Offloading / Equipment Handling
XBC unit sections will be delivered to site in one section.
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.

3.3 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.
