Important notes to Designers
and Installers
1.3 Installation requirements for the
loft mounted Air Handling Unit for
retrofit applications
The successful operation of the Sunwarm Air System depends
entirely upon installation and ongoing maintenance being carried
out strictly in accordance with these instructions.
Additionally, SAP Appendix Q recognition of the Nuaire Sunwarm
Air System is contingent upon adherence to this guide, including
maintenance activities.
Please note that retrofits do NOT form part of
this guide in terms of Appendix Q.
Please read this guide in its entirety before installation and
then repeat the exercise step by step to ensure satisfactory
completion including any recommended maintenance activities .
1.4 Loft inspection
Check to ensure that the loft has adequate ventilation.
Look for ridge vents, tile vents, eaves vents and continuous air
gaps etc. making sure none are blocked. In older properties these
vents may not be provided. However, there should be enough
‘leakage’ to accommodate the requirements of the unit.
Installation of the Solar Air Collectors must be carried out by a
suitably qualified roofing contractor taking account of The
Working at Height Regulations 2005 and in accordance with
CDM Regulations 2007.
A useful way of checking such lofts is to close the hatch, switch
off the lights and look for any daylight penetration.
If you can see daylight it is reasonable to assume that the loft
has sufficient ventilation.
Installation of the Air Handling Unit must be carried out by a
suitably qualified electrician in accordance with the Electricity at
Work Regulations 1989, the 17th Edition IEEE Regulations and
the CDM Regulations 2007.
There may be occasions where a loft is so well sealed that
additional ventilation may have to be provided by the owner
/occupier or the unit installer. This will not only assist the
operation of the unit, but will help prevent possible expensive
structural damage caused by inadequate air movement in the
loft itself.
These instructions are limited to installation in a home with a
“cold roof”. “Warm roofs” vary considerably and advice
should be sought from Nuaire on an individual basis.
Nuaire specified insulated ducting must always be used where
stated for the system to be recognised by Appendix Q within
SAP Regulations.
It should be noted that there cannot be too much ventilation
into the loft.
Additional checks should be carried out as follows:
Warning: Unit must only be installed in a horizontal
position with Nuaire logo on top and not upside down,
at an angle or any other configuration.
1.1 General description
The Sunwarm Air System is a Low Energy Positive Input
Ventilation (LEPIV) unit. Unlike conventional LEPIV units which
only draw in external air via the loft in a “cold roof’, the unit is
capable of drawing in external air from different locations via
three air inlet spigots each fitted with their own low energy
open/close damper. (See figure 1).
The units airflow is controlled via an integral intelligent control
system that measures, and appropriately responds to,
temperatures at the various air inlet locations.
The temperature selected by the occupants on the user control
panel provided will be the delivered air temperature into the
home.
■
Ensure that all water tanks are covered
and sealed.
■
Check that all water pipes are lagged.
■
Ensure that any extract fans are discharging to
outside and not into the loft.
■
Check that the loft hatch is tightly sealed.
■
Ensure all holes in the ceilings are sealed i.e. ceiling
light fittings etc.
■
A visual inspection of flues or chimneys for leakage
in the loft should be carried out by the installer.
If leakage points are found, or if there is any doubt
regarding the same the installer should advise the
house owner/provider and seek instruction from
them before continuing with installation.
■
The Air Handling Unit unit must be able to pass
through the loft access (minimum dimensions
required are 570 x 400 mm).
1.2 Handling
The Solar Air Collectors and the Air Handling Unit are
delivered to site in separate crates suitable for forklift
handling.
There are normally two collectors per dwelling. The units are
packaged individually, net weight 61kg net.
Each Solar Air Collector consists of a sealed unit, which contains
the solar absorber and is heavily insulated and covered on the
top face with a polycarbonate sheet.
WARNING – take all precautions necessary to protect the
polycarbonate whilst handling the collectors.

2.3 Tilt angle
We recommend a minimum tilt angle of 12.5o in order to ensure
good run off of rain water from the surface of the collectors.
The process to be followed will generally be as
shown below:
2.4 Maximum operating pressure
(a) Installation of 2 Solar Air Collectors on the roof,
over battens, over the rafters or sarkin board.
The Solar Air Collectors utilize an automatic temperature control
device as well as other controls to distribute the air throughout
the system. In the unlikely event of all measures failing, the
maximum internal air pressure will not exceed 0.1bar.
(b) Preparing ducting holes in roof.
(c) Installing flashing and weather proofing the collectors.
(d) Installation of a tile vent if applicable and weather proofing.
2.5 Lightening protection
On new buildings, the installation may be phased in line with
the building construction.
There are no specific requirements for installation of Solar Air
Collectors; however, please consult any local regulatory or
precautionary requirements if you live in an area prone to
lightening strikes for protection of your building.
2.1 Installation Solar Air Collectors
The installer should follow all standard safety procedures whilst
working. We recommend use of appropriate personal protective
equipment during installation.
In the northern hemisphere, the collectors are normally installed
on a roof facing South/ South West/South East. Orientation
towards the North will severely compromise the performance of
the system. If in doubt, do not fit until you have checked with
the system designer or Nuaire.
The roof structure must be fit to accommodate the Solar Air
Collectors mass (2 x 61 kg).
Figure 3. 25mm upstand collector .
The location of the collectors on the roof should minimise any
possibility of overshadowing by roof structures, trees or
adjacent buildings.
The panels must be positioned in portrait mode, down the roof,
with the shortest side horizontal with the ridge and/or the
eaves.
Generally, the higher up the roof slope the panels are, the better
is the exposure to solar energy.
Ensure that the collectors are positioned at least one metre from
the base of the roof slope to allow for ductwork connections.
Solar Collector
25mm Collector
upturn
Each collector is essentially a weathered box that has to be
secured and weathered to the roof structure.
Two penetrations are required into the loft space for ductwork
connections at the back of each collector.
Each collector must be centred between two roof rafters to
allow ductwork connections to be made at these points.
Four smaller penetrations, for each collector, are required for
M8 Stud Bars to secure the panels in place.
2.2 Installation options for
Solar Air Collectors
Battens
The Solar Air Collectors can be installed on the rafters or Sarkin
board (in Scotland). This manual shows the installation on the
rafters only. For more information on installation on Sarkin
board, please contact Nuaire.
A 25mm upstand collector is supplied as standard for
installing over the rafters and/or Sarkin board.

4.3 User Control
4.4 Checking the flow rate setting
The user control should be fitted to an appropriate wall (fixings
supplied). Position the control so that the user can gain easy
access. Instructions for fixing are supplied with the control.
The control has three LED lights; one each of green, amber and
red plus one push button to allow system to be set up.
Press and hold the button down for approximately 8 seconds;
the LEDs will go from green through the following sequence:
amber, red, amber & red, all off. Release the button when all
the LEDs are turned off. The red LED will flash to indicate the
flowrate in tens followed by the amber LED which indicate
flowrate in units. For example: 2 red flashes followed by 4
amber flashes means the flowrate setting is 24l/s.
Screw the backplate to the wall. Connect the data cable
(supplied) and clip the control into place. Route the cable to the
loft and connect to the main Sunwarm unit control module panel
(see figure 20).
Secure the cable to prevent accidental dislocation.
Figure 21. User control.
4.5 Setting the flowrate
The selectable flowrate range is between 15 and 40 litres per
second (l/s). The flowrate is split into two halves, tens and units
for adjustment e.g. 2
5 l/s
Power
Power
Tens Units
Press and hold the button until just the AMBER light is lit;
release the button. Press and release the button to increase the
unit setting starting from 0. For example; 3 presses will set the
unit value to 3. The valid range is 0-9. Note this setting works in
a loop so 11 presses produce value of 1. The green LED will flash
after each button press.
Status
Press and hold the button until just the RED light is lit; release
the button. Press and release the button to increase the setting
in tens starting from 0. For example; 2 presses will set the unit
value to 2. Valid range is 1-4. Note this setting works in a loop
so 5 presses produce value of 1. The green LED will flash after
each button press.
Status
Example: set the flowrate to 25l/s, press and hold until amber
light is lit; press and release 5 times. Press and hold until red
light is lit; press and release twice. Press and hold all the LED are
switched off, the red will then flash twice followed by amber
flashing 5 times to indicate 25l/s.
User Control Test
Ensure the power light is on green and the status light is either
green or amber.
If the setting is below 15l/s; then 15l/s will be the default
flowrate. If the setting is above 40 then 40l/s will be the
flowrate.
If the power light is not on check the wiring and connections
between the fan unit and the user control.
The user control as shown in figure 21 above, has a target
temperature setting dial knob and two press buttons (under the
flap) which enable the fan to be switched off or the airflow to be
boosted to its maximum duty.

COMMISSIONING REQUIREMENTS
6.1
General pre-commissioning checks relevant to safe operation consist of the
following:
Ensure that no foreign bodies are present within the fan or casing.
Check electrical safety. e.g. Insulation and earthing.
Check guarding of system.
Check operation of Isolators/Controls.
Check fastenings for security.
6.2
Other commissioning requirements are given in the relevant product documentation.
TRANSPORTATION, HANDLING AND STORAGE
Care must be taken at all times to prevent damage to the equipment. Note that
shock to the unit may result in the balance of the impeller being affected.
When handling the equipment, care should be taken with corners and edges and
that the weight distribution within the unit is considered. Lifting gear such as
slings or ropes must be arranged so as not to bear on the casing.
Equipment stored on site prior to installation should be protected from the
weather and steps taken to prevent ingress of contaminants.
7.0
OPERATIONAL REQUIREMENTS
7.1
Equipment access panels must be in place at all times during operation of the
unit, and must be secured with the original fastenings.
7.2
If failure of the equipment occurs or is suspected then it should be taken out of
service until a competent person can effect repair or examination. (Note that
certain ranges of equipment are designed to detect and compensate for fan failure).
8.0
MAINTENANCE REQUIREMENTS
OPERATIONAL LIMITS
It is important that the specified operational limits for the equipment are
adhered to e.g. operational air temperature, air borne contaminants and unit
orientation.
Where installation accessories are supplied with the specified equipment eg.
wall mounting brackets. They are to be used to support the equipment only.
Other system components must have separate provision for support.
8.1
Specific maintenance requirements are given in the relevant product documentation.
8.2
It is important that the correct tools are used for the various tasks required.
8.3
If the access panels are to be removed for any reason the electrical supply to the
unit must be isolated.
8.4
A minimum period of two minutes should be allowed after electrical disconnection
