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 mm full bore valves on the ow and return connections on the fan

convector.

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.

7 SPARE PARTS

8.1 MAINS ON/OFF SWITCH

Grant Solo units have a factory-tted double pole mains ON/OFF

switch.

SOLO COMPACT AND COMPACTMAX MODELS:

This switch is located under the right-hand end of the front casing. Refer to Figure 10-1.

Figure 8-1: Solo Compact and CompactMAX mains ON/OFF switch (underside of unit)

SOLO HIDEAWAY MODEL:

This switch is located on the right-hand side of the unit. It should

have been set to the ON position before being nally tted in to

the plinth/baseboard.

8 OPERATING INSTRUCTIONS

Figure 8-2: Solo Hideaway mains ON/OFF switch (right-hand

side of unit)

For the unit to operate, ensure that this switch is set to ON and the power supply to the Solo fan convector is on, i.e. the switch on the fused spur serving the unit is set to ON.

Page 15

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.
