1. General
1.1 Description
This manual covers the ‘Classic’ and ‘Natural’
models of the Belgravia Fan Convector range.
‘Classic’ units are the cabinet type intended for
either vertical or horizontal mounting. ‘Natural’
models are free convection units for vertical
mounting. Controls can be contained within the
casing to give a clean outline.
The units can be supplied with internal grilles
for visible surface mounting types or with
plenum and/or spigot connections for concealed
mounting in ceiling or wall space, when short duct
connections may be required to serve the heated
space via optional loose grille assemblies.
The ‘Natural’ unit possesses no motor plate as it
relies upon buoyancy driven airow through the
casing. The following sections relating to the motor
plate and its associated controls do not apply to
this type of unit.
1.2 Receipt and Preparation
The units are wrapped and display the SPC
works order number, model reference, site
reference (where appropriate), handing and site
details. Installation, operation and maintenance
instructions, together with wiring and any special
instructions are supplied with the unit.
On receipt, check that all details are correct to the
Customer Schedules prior to opening packaging.
Damage should be reported to the Carrier and to
SPC Oce immediately.
It is recommended that packaging is kept in
place and the units stored in a safe area until the
necessary services are completed, in order to
avoid the possibility of damage on site.
This document and wiring diagram supplied
should be kept with the unit until electrical
installation is complete.

2.4 Change of Handing
Units will have been supplied with pipework
connections on RHS unless specied otherwise. It
is possible to change the handing of the coil heat
exchanger on site by simply reversing its position
inside the unit.
After removing the front panel the coil is easily
removed by releasing two screws holding it in
position on its two support brackets.
The ow and return pipes pass through holes in
the fan plate brackets and if reversing the coil then
the knock-outs in the non-connection side will
need to be removed. The holes now in the side
from which the connections have moved should
be taped over.
After reversing the coil the screws should be
reattached to the brackets to hold it securely in
place.
2.5 Mounting
2.5.1 Wall Mounting
Vertical units can be low level oor mounted or
high level wall mounted.
Low level units are often supplied with a plinth to
hide pipework and lift the unit from the oor. If
they are supplied with a loose plinth then the fan
convector base screws into the plinth via 6-o M5
threaded inserts.
A series of reinforced 6mm dia holes are tted in
the backplate of the unit as shown in the diagrams
below. The wall should be marked out and drilled
with suitable anchors prior to securing through the
backplate.

2.5.3 Tall units
Tallboy type units for vertical mounting are
supplied in three sections to assist with transport
and movement on site. All three sections should
be screwed together using the screws/nuts/
washers supplied. The assembly should be
undertaken either in the nished position or as
close to it as is practical.
PAGE 8

9IOM 69 Issue 4 – Belgravia Classic Fan Convectors
2.6 Wiring
All electrical work should be carried out in
accordance with current I.E.E. regulations.
See the wiring diagram supplied with the unit for
connection details.
All motors are tted with internal self-resetting
thermal overload protection (see note below) and
are equipped with a motor plate mounted
Anti-surge fuse (see spares list). All units are
supplied with a 2 metre length of 3 core cable as a
ying lead. This is normally coiled within the unit.
The customer should drill and gland to suit the
installation. The supply should be wired through
a suitable means of isolation such as a fused spur
box or similar. Recommended fuse is not more
than 3A (for standalone unit).
2.7 Electric Motor Protection
On ceiling mounted and reverse airow
applications where the fan motor is switched o
for long periods, with hot water still circulating
through the heat exchanger in excess of 82ºC
(180ºF), it is recommended that a system be
employed which automatically closes the hot water
supply valve to prevent damage to the electric
motor due to overheating.
2.8 Pipe connections
Standard units are supplied with ow and return
pipe connections sized at ¾” BSPP female. For
the standard 2 row coil heat exchanger the ow
and return pipes are interchangeable. If the fan
convector is equipped with a 3 row coil which
has ½” BSPP female connections then this will be
an enhanced output coil for use against low hot
water temperatures or owrates. For this type of
coil the connection coming from the leaving air
face should be made the ow and the connection
closest to the fan outlet, on the entering air face,
should be made the return connection. This
ensures that the optimum heat transfer capacity
can be achieved from the coil.
If a modulating valve is tted as a part of an LST
unit then the nal pipe connections will be in
15mm copper and the ow and return pipes
should comply with any arrows stamped on the
valve body.

3.1 Control Wiring
The wiring for internal control options is sited on
the motor plate. Wiring from the motor plate to
casing control options is via split connector break
plugs. Customer wiring should be made to the
Customer Connection Box for other than the
ying lead. Wiring to other than this point may
result in voiding of the warranty.
A wiring diagram showing customer connections
is included with each unit.
For wiring other than that specied on the
Customer’s order, the SPC Technical Department
should be contacted.
3.2 Motor Wiring
The motors are Electronically Controlled. They
have a 230v AC supply but are controlled via a
10v DC signal. A circuit board on the motor plate
has three potentiometers tted which give the
low/normal/high speed.
If only one speeds is specied this will be normal
unless otherwise stated.

Thermostat T-1 On - o
T-2 Change speed
LTC Low water temperature fan cutout
ALTC Adjustable low water temperature fan cutout (remote)
Switches RS-1 On - o
RS-2 Summer - winter
RS-3 Change speed (3 speeds)
**Additional References: Motor plate mounted = B, Case mounted = C, Remote = R
3.4 Thermostatic Operation
The T1 and T2 Thermostats both have graduated
scales to cover their range of operation. Since
the thermostatic bulb is frequently unit mounted
it may be oset by various amounts from the
measured room temperature.
Set the knob at mid-range and adjust to suit
comfort conditions within the room.
The range corresponds to a sensed temperature
range of 10°C to 30°C.
T1 and T2 are adjustable and determine the
comfort room temperature range. Set T2 for the
low and T1 for the high point. Example: T2 16°C
and T1 20°C.
The LTC is not adjustable (45°C) and provides
a fan cut-o for the situation when the water
temperature is not suciently high to provide
warm blown air from the fan convector. The LTC
is mounted at the non-void end of the unit, and
is screwed to a copper disc which is brazed onto
a return bend of the coil.
3.5 Switch Operation
The RS1 switches do not in themselves isolate
the unit.
The RS2 Summer-Winter switch provides an
override for the LTC and T1 (where tted),
enabling the fan to operate in the summer, for air
re-circulation.
The RS3 Change Speed Switch delivers one of
three voltage tappings to the motor. Where used
in a remote application care should be taken
when wiring into the customer connection box to
ensure correct sequencing
