1.1 GENERAL
The Grant Solo range consists of two wall-mounted fan
convectors, the Grant Solo Compact and Grant Solo
CompactMAX, and the Grant Solo Hideaway model designed to t
under kitchen units or in other similar locations.
For heating capacity details on all three models refer to Section 2
of these Instructions.
Grant Solo fan convectors are supplied with a simple electronic
control panel. Refer to Section 10 for further details and operating
instructions. Each fan convector is individually controlled to
provide a exible and responsive means of heating each space.
They are designed to be integrated into low temperature heating
systems using air source heat pumps, condensing oil, gas and
biomass boilers, etc.
Each Solo fan convector requires a 3A fused 230V 1ph 50Hz
electrical supply. Refer to Section 5 for further details.
A double pole mains ON/OFF switch is factory tted to all Grant
Solo units.
On the Solo Compact and CompactMAX models this is located
under the right-hand end of the front casing. On the Solo
Hideaway model this switch is located on the right-hand side of
the unit.
The steel chassis of the Solo Compact and Solo CompactMAX is
xed directly to the wall. No wall mounting brackets are required,
keeping the unit as close to the wall as possible.
With the Solo Hideaway unit, the steel chassis is xed directly to
the plinth or similar when tting under kitchen units or other xed
units.

1.2 OPERATING PRINCIPLES
The Grant Solo range of fan convectors use backward curved
impellers and they are designed to ensure zero convection and
therefore minimal heat emission when the fan is not running. This
eliminates the need for any radiator control valves.
The heat exchanger does not touch the outer case but is insulated
from it, providing a low casing surface temperature regardless of
the water ow temperature. The top grille prevents contact with
the heat exchanger.
With the electrical supply to the Solo fan convector switched
on; when the water temperature sensor (located in the heat
exchanger) detects that the water temperature entering the unit
exceeds 29°C the unit will start.
The air temperature is then sampled over a 60 second period by
the air temperature sensor located at the rear of the unit.
The user can then set the required room air temperature between
18 to 24°C via the control panel on the front of the unit. Refer to
Section 10 - Operating Instructions for further details on setting
the required air temperature.
The Grant Solo microprocessor control system predicts the air
temperature at occupant level as low-level temperatures are
always colder than at occupant level and would provide incorrect
data on which to determine the level of heat output required.
If the difference between the sampled air temperature and the air
temperature setting on the unit is greater than 1°C the heat output
of the unit is increased with the fan running on the ‘High’ setting.
When the air temperature rises and the difference between the
sampled air temperature and the air temperature setting on the
unit is less than 1°C the heat output is decreased with the fan
running on the ‘Low’ setting.
When the air temperature reaches the setpoint, the unit is
switched off and enters a ‘sleep’ period for 8 minutes. After this
the air temperature is then sampled over a 60 second period.
If there is no change and no heat output is required, the unit
enters an 8 minute ‘sleep’ period again before sampling the
air temperature for 60 seconds again, until a difference exists
between the sampled air temperature and the air temperature
setting on the unit.
The Grant Solo unit will then repeat the start-up sequence again.

BOOST FUNCTION
The boost function is activated by pressing the Boost button
on the control panel fascia. Refer to Section 10 - Operating
Instructions.
The boost function overrides the normal temperature control and
runs the fan at higher ‘Boost’ level for a period of 20 minutes to
provide a greater heat output than the normal operation.
After this period has elapsed the Solo unit automatically returns
to the normal temperature control with the fan operating at either
‘Low’ or ‘High’ setting as dictated by the difference between the air
temperature and the air temperature setting on the unit.

3.1 INTRODUCTION
Each Solo fan convector requires a 3A fused 230V 1ph 50Hz
electrical supply and is tted with a terminal block for easy and
quick electrical connection. Refer to Section 5 for further details.
Please ensure that Solo fan convectors are protected from dirt,
rubble, etc. and it is suggested to wait for all other building and
decorating works to be completed before nally xing in the
required location.
3.2 REGULATIONS
The Installation of a Grant Solo fan convector must be in
accordance with the following recommendations:
• Building Regulations for England and Wales or the Building
Standards for Scotland, as appropriate.
• Any local Byelaws which you must check with the local
authority for the area concerned.
• The Water Supply (Water Fittings) regulations 1999 or
the water Supply (Fittings) (Scotland) Bylaws 2014, as
appropriate.
• Applicable Control of Pollution Regulations.
The installation should also be in accordance with the latest
edition of the following British Standard Code of Practice (and any
relevant amendments):
• BS EN 12828 (Heating systems for buildings. Design for
water-based heating systems).
• BS EN 14336 (Heating systems in buildings. Installation and
commissioning of water-based heating systems).
• BS 7593 (Code of Practice for treatment of water in domestic
hot water central heating systems).
• BS 7671 (Requirements for Electrical installations, IET Wiring
Regulations).
• BS 7291 (Thermoplastic pipe and ttings systems for hot and
cold water for domestic purposes and heating installations in
buildings. General requirements.
• BS 7074-1 (Application, selection and installation of
expansion vessels and ancillary equipment for sealed water
systems. Code of practice for domestic heating and hot water
supply.
3.3 LOCATION
Solo Compact and CompactMAX fan convectors should be
positioned with the lower edge approximately 75-100mm above
the skirting level.
The Solo Hideaway fan convectors are tted into the plinth or
baseboard of xed units, e.g. kitchen units. Refer to Section 3.7
for dimension of the opening required. The lower edge of this
opening must be at least 12mm above the nished oor level.
The outlet from all Solo fan convectors must be unrestricted, e.g.
no shelves above the wall hung Solo Compact and CompactMAX
units.
Ensure that heating system ow/return pipework is not run along
the wall or skirting directly below either the Solo Compact or
Solo CompactMAX fan convectors. The warm air rising from the
pipework will affect the operation of the air temperature sensor
tted at the rear of the fan convector and may result in reduced
heat output from it.
3.4 SYSTEM REQUIREMENTS
Grant Solo fan convectors can be used on either open vented or
sealed central heating systems.
The pressure characteristics of the Grant Solo fan convectors
were designed to facilitate even ow sharing by ensuring that
the pressure drop at various ow rates considerably exceeds the
pipework friction loss.
Care must therefore be taken to ensure that adequate pumping
capacity exists to guarantee adequate ow through each fan
convector unit. A 6metre head pump is suggested.
A maximum of approximately six to eight Solo units on a circuit,
with 22mm ow and return pipework with 15mm radiator tails, is
recommended.
It is suggested that reverse return pipework be used where
possible. Refer to Figure 2-4.

Section 3: InstallationPage 8
OPERATION WITH RADIATORS
Grant Solo fan convectors are ultra-low water content heat
emitters and should ideally not share heating circuits with
conventional radiators, as this may result in a reduced ow
through the fan convectors.
If this cannot be avoided and the fan convectors must be added
to an existing radiator circuit the following requirements must be
met:
a) The ow and return pipework must be 22mm minimum.
Smaller pipework will result in poor or no heat output from the
fan convector(s).
b) When installed, rst shut off the conventional radiator(s) to
check that the fan convector(s) operate correctly.
Then, turn on the radiator(s) and adjust the lockshield valve
on each radiator and reduce the ow until the fan convector(s)
operate.
3.5 PIPEWORK MATERIALS
The Grant Solo fan convectors can be used with both copper
and plastic pipe. Where plastic pipe is used it must be of the
oxygen barrier type and be the correct class (to BS7291-1) for the
application concerned.
On sealed systems, if plastic pipe is to be used, the installer must
check with the plastic pipe manufacturer that the pipe to be used
is suitable for the temperatures and pressures concerned. Plastic
pipe must be Class S to BS7291-1.
Two exible hose connections will be required for installation of
the Grant Solo Hideaway fan convector. These are supplied with
the unit.
3.6 PIPE CONNECTIONS
SOLO COMPACT AND COMPACTMAX MODELS:
Remove the front cover to access the ow and return pipe
connections. Refer to Section 3.6 or 3.7, as required, for details
on removal of the front cover.
The ow and return connections are located at the left-hand side
of the unit.
The ow and return pipework can enter/exit the unit either
a) To the rear of the unit through the wall, or
b) To the bottom of the unit, through the opening in the lower
casing.
It is recommended that 15mm isolation valves (not supplied)
are tted to the ow and return connections before connecting
the ow and return pipework. These valves must be of the ‘full
bore’ type to ensure no added restriction to the ow and return
pipework.
SOLO HIDEAWAY:
The ow and return connections are located on the right-hand
side of the unit.
To allow the unit to be fully withdrawn from the plinth or base
board in which it is tted, without having to disconnect it from the
system, two exible hose connections (supplied) will be required
for installation of the Grant Solo Hideaway fan convector. These
are long enough to allow the fan convector to be completely
removed from the plinth/baseboard when they are connected.
These will be connected between the system ow and return
pipework, located at the rear of the xed kitchen unit, and the 15

4.1 GENERAL
Grant Solo fan convectors require a ~230V 1ph 50Hz electrical
supply protected by a 3 Amp fuse.
A fused double pole switch, with contact separation of at least
3mm in both poles, should be used for connection to the mains
electrical supply, serving the boiler and heating system controls
only.
For the Solo Compact and Solo CompactMAX this switch can be
located on the wall next to the fan convector.
For the Solo Hideaway, this switch can be located in a convenient
position for the user to access when necessary, e.g. on the wall
above kitchen unit/worktop level or inside the kitchen unit.
For the UK, the electrical installation must be carried out by a
competent installer in accordance with the requirements of the
Electricity at work Regulations 1989 and BS7671:2018 – IET
Wiring Regulations 18th Edition.
If installed in the Republic of Ireland, the wiring installation must
comply with all ETCI rules. All the wiring and supplementary earth
bonding external to the boiler must be in accordance with the
above-mentioned wiring regulations.
Do NOT interrupt the electrical supply to the Grant Solo with any
external controls.

Section 8: Operating Instructions and Section 9: Cleaning Page 15
8.2 CONTROL PANEL
Grant Solo fan convectors are supplied with a simple control
panel. Refer to Figure 1-3.
This allows each Solo unit to be individually set to suit the room or
area in which it is installed.
The functions of the buttons and indicator lights are as follows:
ON/OFF BUTTON
When the ON/OFF button is pressed for at least 1 second it will
start the operation of the Grant Solo unit – provided that the water
ow temperature is at least 29°C AND the room air temperature
is low enough (i.e. below the air temperature setting of the Solo
unit). See section on ‘Temperature indicator lights’ below.
To stop the unit operating, press the ON/OFF button for at least 1
second.
TEMPERATURE INDICATOR LIGHTS
There are four temperature indicator lights that display the air
temperature setting of the Solo unit, and whether that temperature
setting has been achieved or not.
These indicate increasing temperature settings from the lowest on
the left to the highest on the right, as follows:
• 18°C – indicator light with single bar
• 20°C – indicator light with two bars
• 22°C – indicator light with three bars
• 24°C – indicator light with four bars
TO SET THE REQUIRED AIR TEMPERATURE
Press the ON/OFF button momentarily – the lowest (single bar)
indicator light will ash slowly indicating that the air temperature
setting is 18°C.
TO INCREASE THE SETTING
Press the ON/OFF button again momentarily – the next (two
bars) indicator light will now ash slowly indicating that the air
temperature setting is now 20°C.
Press the ON/OFF button again momentarily to increase the
setting further (if required) – the next (three bars) indicator light
will now ash slowly indicating that the air temperature setting is
now 22°C.
Press the ON/OFF button again momentarily (if required) and the
right hand (four bars) indicator light will now ash slowly indicating
that the air temperature setting is now at the maximum (24°C).
Pressing the ON/OFF button again momentarily will return the
air temperature setting to the minimum (18°C) and the left hand
(single bar) indicator light will now ash slowly.
The selected indicator light will continue to ash slowly whilst the
temperature is being raised. When the air temperature reaches
the setpoint, the indicator light will stop ashing and become
continuous. The Grant Solo unit will then stop heating until
needed again.
! NOTE !
It is NOT possible to adjust the temperature setting if the
water ow temperature is at less than 29°C.
ALARM LIGHT
The Alarm light will ash if the water ow temperature is less than
29°C.
BOOST/COOL BUTTON
Press this button momentarily whilst the Solo unit is operating and
the normal Solo temperature control will be overridden for a period
of 20 minutes to provide a higher output than available in normal
operation.
The temperature indicator light will go off and the Alarm/Boost
light will come on to indicate the Solo unit is operating in the Boost
mode.
To stop the Boost function
Press the Boost button momentarily at any time during the 20
minute boost period.
After 20 minutes have elapsed, the Solo unit will automatically
revert to the normal temperature control. The Alarm/Boost light will
go off and the temperature indicator light will revert to the original
setting.
Momentarily pressing the Boost button again will re-start the boost
function for another 20 minutes.
SUMMER COOLING FUNCTION
In the summer Solo fan convectors can be used to provide air
movement to give passive cooling.
To use this function, press BOTH the ON/OFF and Boost buttons
at the same time for more than 1 second.
The water temperature control will be ignored and the fan will run
at the highest (boost) level for maximum air ow until the Solo unit
is switched off. The Alarm/Boost light will come on in this mode.
To switch off the summer cooling function, press BOTH the ON/
OFF and Boost buttons at the same time for more than 1 second.
! NOTE !
The Summer cooling function will NOT automatically
switch off after a xed period (as with the Boost function)
but will remain on until BOTH the ON/OFF and Boost
buttons are presses at the same time.
SPECIAL FUNCTION LIGHT
This light is not used and will not be lit during the operation of
the fan convector. This does NOT indicate a fault with the fan
convector.
Whilst it is not necessary for the Grant Solo fan convectors to be
regularly serviced, a limited amount of cleaning is required from
time to time.
Only use a moist cloth to clean the outer surfaces of the Solo fan
convectors. Do NOT use any abrasive cleaners, cleaning liquids
or aerosols.
9 CLEANING
The warm air outlet grille on the top of the Solo Compact and Solo
CompactMAX and the front grille of the Solo Hideaway can be
vacuumed clean.
The air inlet lters on the Solo Hideaway (located either side of
the warm air outlet grille) are not removeable or replaceable. They
can be vacuum clean from the front.
