2.0 INTRODUCTION
2.1 OPERATION
The packaged supply and extract unit shall be manufactured from
Magnelis corrosion resistant steel, with 50mm double skinned
panels and anodized aluminium frame. All external fittings and
fixings shall be stainless steel, aluminium or non-metallic. All
panels and frames will be of a totally thermally broken design,
complying with the following specification in accordance with The
unit shall include the following items: -
•Thermal Wheel HX: A high eciency, ERP compliant heat
exchanger with automatic bypass, complete with condensate
trays.
•G4 pre-filter and F7 main supply filters shall be fitted with
a single M5 bank present on the extract side. Slides for
alternative panel and bag options shall be present and
pressure drop monitoring for maintenance notification will be
included. Performance optimised backward curved impellers
and IP54 EC motors shall be used to provide low specific
fan powers and stepless speed control without tonal noise
generation.
•Fan pressure transducers shall be fitted for constant
pressure/flow control and energy monitoring.
•Internal lighting and inspection portholes shall be present on
all fan modules.
•An electric -up heater battery shall be fitted on EHP units,
complete with power controller to allow output modulation
from the unit control.
•A fail-safe auto-reset safety device shall be present.
•Internally installed Heat recovery ASHP with dual compressor
operation.
All hinged access panels shall be lockable and removable
(with a common key for all) allowing full maintenance access
from the side. The unit has the option of left hand or right hand
arrangements in direction of supply air flow.
Each Ecosmart heat pump system is charged with R32 refrigerant
gas and is controlled via Carel C.pco plc controllers, each heat
pump system will operate to control the supply air temperature
(set via the BPS Ecosmart control).
Each system will recover and utilise heat from the exhaust air DX
coil of the BPS unit and transfer this heat/energy eciently via
the refrigeration cycle to the supply air DX coil in heating mode.
Each system will also oer pre-cooling of the supply air (set
temperature by BPS Ecosmart controller).
The heat pump systems are installed between the thermal
wheel allowing for very ecient heat recovery system. The
complete Heat pump system can slide out for easy of service and
maintenance works.

2.2 Dual Compressor System
Automatic Defrost Control strategy – when the build-up of frost in
the exhaust coil reaches a limit the dual system will automatically
respond and start warming up the second system (on completion
of system that is in defrost, it will not start when the defrost is
active) to ensure the unit provides continuous ventilation.
In very cold conditions an electric back-up heater is installed in
the supply air reducing any risk of cold air being supplied to the
building, this heater can also be used as backup in case of a heat
pump system failure.
Lower Energy Consumption – A dual compressor system
uses less energy than one large single system providing the
opportunity to make energy savings whilst ensuring the total
energy consumed is minimized.
Greater longevity – A dual system with duty share will prolong the
working life of the components.
•Guaranteed ventilation 24/7 – A dual system will still provide
50% ventilation to the building if the one system fails.

The heater can also be used as a backup heat source in case of
any issue with either heat pump system.
The heater is positioned in the supply fan section after the supply
fan and is accessed from the fan motor access door (Figure 2).
4.0 DELIVERY & 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 ooading by
the purchaser.
No responsibility will be accepted for damage sustained during
the ooading 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.
4.1 Unit Ooading and Handling
The weight of unit modules and palletised items is displayed
on the packaging. Some of the modules have an uneven
weight distribution and this will be indicated by labelling where
appropriate.
Ooading and positioning of the equipment is the responsibility
of the purchaser, and should only be performed by competent
personnel following an appropriate risk assessment.
To ensure that the delivery vehicle is loaded according to the
planned method of ooading, Nuaire must be notified to
ensure coordination. When ooading, care must be taken to
ensure that the AHU is kept level at all times.
To ensure that no roof damage occurs additional timber
packaging must be used.
4.2 Base Frame Lifting Points
When units are constructed of multiple modules each module will
have it’s own individual base frame, which is then connected to
the next to assemble the full system.
Only individual modules should be lifted or manoeuvred. The
units must not be lifted or manoeuvred pre-assembled.
All base frame sections will have 50mm square lifting holes at the
end of each side to enable lifting. In addition to this, covered fork
lifting channels are located across the width of the base frame, if
the module length is sucient to allow this. For shorter modules
the fork lifting points will be along the length of the section,
without a covered channel (Figure 13).

Nuaire | Western Industrial Estate | Caerphilly | CF83 1NA | nuaire.co.uk
BPS HP-COInstallation Manual
In this product range, several unique concepts have been
implemented with a view to simplifying the installation design.
•The unit must be installed with at least 750mm clearance
from a wall/barrier. With this absolute minimum clearance,
the unit may be connected to the power supply and control
connection.
•With this clearance, unit filters may be changed, and the fans
coils, heat exchanger and condensate tray may be inspected
and cleaned if necessary.
•The electrical heater settings, and all other control
adjustments are similarly accessible.
•Side access, where possible, is preferred in all cases in terms
of safe working access to the equipment under the CDM
regulations.
4.3 Unit Packaging
Unless otherwise specified, unit sections will be delivered to site
covered in “shrink wrap” polythene, which should provide a more
than adequate level of protection against inclement weather.
Should alternative methods of unit protection be required (i.e.
timber, Corex, or flame retardant materials), Nuaire Limited should
be notified of the specific requirements at the pre- contract
stage. Waste must be disposed of by a registered waste carrier in
accordance to national regulations.
4.4 Unit Storage
The equipment must be stored in a dry, internal location.
Ductwork connection apertures should be sealed against
the ingress of dust, water and vermin. Note that units that
are intended for external locations are generally not fully
weatherproofed until their installation, including ductwork
connections, is complete.
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.

BPS HP-COInstallation Manual
7.0 MECHANICAL INSTALLATION
Installation must be completed by competent persons, in
accordance with good industry practice and should conform to all
governing and statutory bodies i.e. IEE, CIBSE, etc.
The unit should stand upright and level on the floor, foundation
or supporting steelwork which should be rigid, flat and level and
should be capable of supporting the weight of the unit including
water or refrigerant in the coils. Nuaire takes no responsibility for
the coordination of support.
7.1 Unit Location
To prevent possible reintroduction of contaminated air through
the outside air intake, the unit should be located away from
building flue stacks or exhaust ventilators.
Once assembled and in position, sucient free space must be
available adjacent to the unit for future inspection, maintenance,
component service, repair and replacement and connection of
services. It is recommended that at least the unit width (vertically
arranged units) + 100mm be allowed. A minimum of 600mm is
required for regular maintenance.
Sucient clearance for U-traps on condensate drain and
overflow
connections should also be considered by the purchaser.
7.2 Air Leakage
Loading, transportation, o loading and site positioning can cause
the air handling unit structures to move, therefore panel seals will
not always remain fully intact.
It is inevitable that in such cases, re-sealing of the units panels
and joints may have to be carried out on site for the air-handling
units to achieve the required leakage classification. Door locking
mechanisms may also have to be adjusted.
Nuaire cannot be held responsible for the units failing a site
leakage test if the above have not been carried out correctly.
7.3 Module Joints
After unwrapping, temporarily remove the rubber weatherproof
cover strip and M10 base frame bolts from any modules and store
in a safe location for later use.
Apply the sealing gasket as necessary to the mating faces of the
unit frames. Typically the sealing gaskets are pre-fitted to the heat
exchanger module; ancillary modules will be provided with a roll
of sealing gasket for on-site fitting.
Make the unit joints in the following order:
•Left and right hand side M10 bolts between the modules’
base frames (Figure 14).
•Left and right hand side M6 Lower 3 axis alignment clamps
(Figure 15).
•Left and right hand side M6 Middle 3 axis alignment clamps.
•Left and right hand side M6 Upper 3 axis alignment clamps.
Air leakage, air blow marks to the unit casings and unacceptable
noise levels could result if the correct installation procedures are
not employed.
Prior to making the unit joints, you must ensure the base
frames of adjoining modules are fully touching along the width
of the unit. Failure to do so can result in deformation of the
unit frame when using the three axis alignment clamps.

7.5 Internal Connections
There are a number of internal electrical connections that need to
be completed prior to starting /commissioning the unit.
When making the wiring connections, the sensor loop (Figure 18)
must be removed and relocated to the end of the unit.
Access is available in the fan plate to allow electrical/wiring
connections to be made between modules (Figure 19).
18 Sensor Loop Connection
19 Fan Plate Access Location
7.6 Thermal Wheel Drive / Belt Tension
Thermal wheel modules can be delivered with transport packing
blocks, ensure any transport blocks are removed prior to
operation of the thermal wheel.
The thermal wheel belt is unhooked to prevent the thermal wheel
belt from stretching during transportation.
The thermal wheel motor is attached via a hanging motor bracket.
To install the belt lift the spring motor upwards, hook the belt onto
the pulley and slowly release the motor.
Ensure that the rotation sensor is aligned with the sensing
studs, as this can become misaligned during transport/
installation thus causing a fault signal.
7.7 Weather Resistant Units
The units are supplied in multiple sections and have weather
resistant roof components that must be fitted and sealed after
the unit sections are bolted together. All necessary fixings are
supplied with each unit and are normally bagged and located
within the fan section. Suitable mastic sealant is to be provided by
others.
Where the weatherproof roof assembly of two sections meet, the
metal hinged weatherproof cover strip must be closed to seal the
seam between unit sections and fixed with the bolts provided.
The equipment must not be exposed to the weather in an
unassembled or partially assembled state. All roof terminal,
ductwork, sealing and assembly work must be completed before
the unit can be considered weather resistant.
7.8 Unit Connections
7.8.1 Ducting
Nuaire do not provide ductwork connections with units,
instead the open ended framework should be utilised.
Flanged connections are available as an option, refer to
technical documents for information relating specifically to the
manufactured unit.
7.9 Filters
20 Filter Side Withdrawal
7.9.1 Filter Removal
Filters will be provided in banks on suitable slide rails, so that they
can be withdrawn from the access side of the unit. Dierential
"Dirty Filter" pressure switches are fitted as standard.
7.9.2 Spare Filters
If specified with order, spare sets of filters will be provided and
should be stored in a clean, dry environment. Should you require
spare filter media, please contact Nuaire.
7.10 Control Dampers
Care should be taken to ensure that all spring return actuators
have stopped running and completed their stroke. If not, the
connection needs to be loosened and the actuator should be left
to drive until the motor stops running.
When the unit is powered, dampers should be checked to ensure
that they operate freely and close tightly.
Where dampers are protected with a roof terminal, the roof
terminal can be removed for access to the main damper. Access
to the actuator can be from the side of the roof terminal without
the requirement of removing the roof terminal (Figure 21).

7.11 Damper / Roof Terminal Assembly
The inlet/outlet dampers and roof terminals are pre-assembled
(for BPS sizes 07, 12 and 17) on a double skinned and insulated
panel. The panel is easily fitted to the unit with a series of quarter
turns (provided with a locking key) (Figure 23).
23 Inlet / Outlet Damper / Terminal Quarter Turn Fixings
7.12 Supporting Ancillary Items
All ancillary items that are supplied without individual base frames
require safe suitable support (supplied by others). This includes
but is not limited to single attenuators, terminals and dampers etc.
7.13 Installation Inspection
•Thoroughly inspect the unit after installation is complete.
•The inside of the unit should be checked; any objects which
may have been left should be cleared.
•Check fan impellers, scrolls and outlets.
•Remove any transit protection fittings that may be attached to
the fan or motor base frame, and that all traps are primed.
•Close all access door seals for damage, and replace any
panels that have been removed.
8.0 ELECTRICAL INSTALLATION
The electrical wiring must be carried out by competent persons,
in accordance with good industry practice and should conform to
all governing and statutory bodies i.e. IEE, CIBSE etc.
8.1 Main Unit Power Supply
The control is powered by a 400Vac 50Hz 3 phase & Neutral
supply. This must be isolated local to the unit and fitted with
appropriate over-current and fault protection.
8.2 Electric Back-Up Heater Installation
The back-up heater, if factory fitted, is installed within the unit and
just requires a separate power supply to the isolator.
The back-up heater's isolator is mounted on the supply fan
section
(Figure 24).
Please check the power rating of the heater before selecting the
cable size.
24 Location of the top-up heater isolator
8.3 Top-up Heater Operation
The heater output is controlled via a 0-10v signal from the
Ecosmart controller. The temperature setting of the controller
is automatically set to a 2°C lower oset of the supply air
temperature setting.
i.e. If the supply air setpoint is 22°C, then the top-up heater
setpoint will be 20°C.
This 2°C oset is factory set and cannot be changed, for further
information please contact the Nuaire aftersales team.
The electric top-up heater will only operate when a heating
signal is sent to the heat pumps. When a cooling signal is sent
to the heat pumps the function of the heater is prohibited.

8.7.3 Fan Start Delay
A fan start delay can be imposed to allow the damper time to
open. This is adjustable via display screens or commissioning
tools.
If an I/O damper is fitted, it must be wired to the fan run relay, and
the relay supplied with the relevant supply voltage.
If required the damper end point relay can be connected in series
with alarm circuit 2 to monitor for damper faults. The multi-state
value ‘IO Damper Fitted’ must be set to yes. This will allow the
system to ignore alarm circuit 2 if the fans are not running and
dampers are closed.

8.10 Terminal Wire Connections
8.10.1 Push In Termination
Stripped solid conductors, fine-stranded conductors with ferrules,
or ultrasonically “bonded” conductors are simply pushed in until
they hit the backstop. No tools are required.
8.10.2 Termination Of Fine Stranded Conductors
Open the clamp by inserting an operating tool (as shown below)
until it clicks into position. Then insert the conductor and remove
the operating tool to complete the connection.
27 Wiring a Conductor to a Terminal
8.10.3 Conductor Removal
Insert an operating tool in to the operating slot to remove
the conductor, just like the original CAGE CLAMP® terminals
blocks.
28 Removing a Conductor from a Terminal
8.10.4 Jumpers
Terminal blocks can be commoned together to increase the
number of terminals at the same potential using push-in jumpers.
In these cases the terminals are treated as one conductor.
29 Removing a Jumper Pin
8.10.5 Jumper Removal
Insert the operating tool blade between the jumper and the
partition wall of the dual jumper slots, then lift up the jumper.
30 Removing a Jumper
8.10.6 Double Deck Termination Block
Each deck has a dierent potential (2-conductor), which creates
a space saving on the rail. Decks can be commoned to adjacent
terminal blocks and / or the top to the bottom deck.
31 Double Deck Conducting Paths
8.10.7 Earth Terminals
The earth terminal block (green/yellow) has a direct electrical
connection to the DIN rail, with the earthing foot (earth connection
only).
