WARNING – THIS APPLIANCE MUST BE EARTHED
The electrical installation must be carried out by a competent
electrician, and be in strict accordance with the current I.E.E.
regulations for Electrical Equipment in Buildings.
The wires in this mains lead are coloured in accordance with the
following code :
GREEN AND YELLOW :
EARTH
BLUE
: NEUTRAL
BROWN
:
LIVE
BLACK
:
PILOT
WIRE
- see also ‘Pilot Wire Connection’.
The heater is fitted with a length of flexible cable type H05VV-F
size 4 x 1.0mm2 for connection to the fixed wiring of the premises
through a suitable connection box positioned adjacent to the
heater.
A means for disconnection must be incorporated in the fixed
wiring of the premises in accordance with the wiring rules. The
supply circuit to the heater must incorporate a double pole
isolating switch having a contact separation of at least 3mm.
Pilot Wire Connection
The BLACK control wire is designed to carry a signal from slot in
or wall mounted Dimplex programmers. If, however a programmer
is not being used, the pilot wire should be isolated in accordance
with the current IEE Wiring Regulations.
IMPORTANT - DO NOT connect the BLACK pilot wire to earth.
Care should be taken with the installation of the pilot wire(s) as
when switching to background (set back) they become energised
at 240V although only at a current of less than 100mA. In every
case a suitable means of isolation must be provided for the pilot
wire and marked to indicate that two sources of supply may be
present at the heater.
Where pilot wires are installed separately from the heater final
sub-circuit they should be protected, double insulated and carry
their own integral earth continuity conductor.
Supplementary Earth Bonding
Should Equipotential Earth Bonding be required the earthing
conductor in the supply cord is deemed to provide the
supplementary bonding connection (see Regulation 547-03-05,
17th Edition I.E.E. Wiring Regulations).
Please note that lit cigarettes, candles and oil burners,
combined with the convection effect of electric heaters
can cause soot deposits to build up on the surface directly
above and to the sides of the heater. This is not a fault of
the heater. Extensive burning of candles or smoking in the
operating environment of this product can produce heavy
discoloration within a few months of use.
