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.

Connect the electrical supply to the fan convector as follows:
sOLO COmPaCt anD sOLO COmPaCtmax
Remove the front cover from the fan convector (if not already
removed).
To do this, unscrew and remove the three fixing screws from
along the lower edge of the front cover.
Pull outwards the lower front edge of the front cover and then lift it
off the unit.
The electrical supply terminal block is located at the lower right-
hand side of the fan convector. Refer to Figure 4-1.
Pass the cable through the hole with grommet and the cable
restraint – both located at the right-hand end of the fan convector.
See Figure 4-1.
Connect the mains supply cable (from the fused double pole
switch) to the terminal block as follows:
•
Terminal L: Live – Brown wire
•
Terminal N: Neutral – Blue wire
•
Terminal P
E
: Earth – Green/yellow wire
Secure the cable in the cable restraint to prevent it being pulled
out of the terminal block.
Replace the front cover on the fan convector and secure with the
three screws along the lower edge.
Switch on the electrical supply to the fan convector at the fused
double pole switch.
sOLO HiDEaWaY
The Solo Hideaway is supplied with a pre-wired 1mm
2
3-core
cable 1,300mm long for connection to the electrical supply.
This can be connected directly to a fused double pole switch
located under the kitchen unit.
Alternatively, a 3-pin 13A plug (fitted with a 3A fuse) can be fitted
to the cable for connection to a 3-pin socket under the kitchen
unit and this socket is fed from a fused double pole switch located
either within a kitchen unit or above the worktop level, as required.
Switch on the electrical supply to the fan convector at the fused
double pole switch.

Ensure that the system is filled and vented and that each Solo fan
convector has also been vented. Refer to either Section 3.6 or 3.7
as required.
Switch on the mains electrical supply to the fan convector at the
fused isolator.
Switch the mains ON/OFF switch to ON.
On the Solo Compact and CompactMAX models, the mains
switch is located under the right-hand end of the front casing.
Refer to Figure 8-1.
On the Solo Hideaway model, the mains switch is located on the
right-hand side of the unit and should have been set to the ON
position before being finally fitted in to the plinth/baseboard. Refer
to Figure 8-2.
Switch the boiler or heat pump on and set the heating system
controls to call for heat.
Operate the heating system to raise the flow temperature

Check the operation of the Solo fan convector(s) as follows:
Press and hold the ON/OFF button on the Solo fan convector
control panel to switch the unit on.
The Alarm/Boost light will flash until the water flow temperature
reaches 29°C.
When the flow temperature reaches at 29°C the Alarm/Boost light
will stop flashing and one of the temperature Indicator lights will
be lit – either flashing or constant.
Using the ON/OFF button, set the air temperature to each one of
the four settings in turn to check their operation and then finally
set the air temperature to the required setting.
! nOtE !
it is nOt possible to adjust the temperature setting if the
water flow temperature is at less than 29°C.
Press the Boost/Cool button to check the boost function operation.
Press the Boost/Cool button again to switch the boost function off.
Set the heating system controls to the user’s requirements.
