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 1.0mm
2
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 a wall mounted Dimplex
programmer. If 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 (setback) 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
544.2.5, 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 discolouration within a few months of use.
