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 flow
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 flow 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, first 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 flow 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 flexible 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 flow and return pipe
connections. Refer to Section 3.6 or 3.7, as required, for details
on removal of the front cover.
The flow and return connections are located at the left-hand side
of the unit.
The flow 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 fitted to the flow and return connections before connecting
the flow and return pipework. These valves must be of the ‘full
bore’ type to ensure no added restriction to the flow and return
pipework.
sOLO HiDEaWaY:
The flow 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To allow the unit to be fully withdrawn from the plinth or base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 fitted, without having to disconnect it from the
system, two flexible 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 flow and return
pipework, located at the rear of the fixed kitchen unit, and the 15
mm full bore valves on the flow and return connections on the fan
convector.
3.7 instaLLatiOn PROCEDURE:
sOLO COmPaCt anD sOLO
COmPaCtmax mODELs
1. Carefully remove the Solo fan convector unit from the
packaging.
2.
Lay the unit on a flat surface (floor, table, etc.) with the front
cover facing upwards.
3.
Unscrew and remove the three fixing screws from along the
lower edge of the front cover.
4. Lift the lower front edge of the front cover and then slide it
forwards and off the unit.
5. Safely store the front cover for now where it will not be
damaged or scratched for re-fitting after the Solo Compact or
CompactMAX fan convector has been installed.
6. Position the unit against the wall so that the lower edge is
approximately 75-100mm above the skirting level.
7. Use a spirit level on the top of the unit to ensure it is level
and mark the position of the three fixing holes in the back
plate onto the wall. Refer to Figure 2-5 0r 2-6 for the fixing
hole positions.
8. Remove the unit from the wall and drill the three holes to take
a suitable wall fixings (not supplied).
9.
Securely fix the unit to the wall using three screws (not
supplied).
10.
Remove the rubber bungs from the flow and return
connections on the fan convector and check that the bleed
screws on the flow connection are both closed.
It is recommended that 15mm isolation valves (not supplied) are
fitted to the flow and return connections before connecting the
flow and return pipework.
These valves must be of the ‘full bore’ type to ensure no added
restriction to the flow and return pipework.
