Installation
Before undertaking installation work, ensure the electricity supply
is disconnected from any relevant fixed wiring.
Supply cable is not provided with this appliance, and a competent
electrician should therefore install it.
The appliance must be fitted horizontally with the cable or conduit entry
at bottom right. It should be mounted such that the underside is at least
350mm above the floor and the top of the heater is 150mm below any
overhanging shelf or obstruction.
This heater must be used on an A.C.~ supply only and the voltage
marked on the heater must correspond to the supply voltage.
To comply with the I.E.E. Wiring Regulations, the appliance must be
earthed; the supply circuit must be adequate for the input of the
appliance, and the circuit protected by a suitable 13A fuse. A suitable
termination to the fixed wiring of the premises must be provided adjacent
to the final position of the appliance. In this instance, such a termination
can be a double-pole switch with a contact separation of at least 3mm in
all poles.
The heater must not be located immediately below a socket-outlet.
Electrical
WARNING : THIS APPLIANCE MUST BE EARTHED.
After ensuring the electricity supply is not live, electrical connections can
be made, either to an adjacent double-pole switch having a contact
separation of at least 3mm in all poles or to a plug-top for use in a
standard 13A socket.
If the latter: Connect Green and Yellow wire to plug terminal marked E
or Green or Green and Yellow. Connect Blue wire to plug terminal
marked Nor Black. Connect Brown wire to plug terminal marked Lor
Red.
Refit cover, first hooking top over the back of the unit and then securing
the bottom by refitting the two screws under the bottom edge. The
appliance is now ready for use and the electricity supply can be
reinstated.
THESE INSTRUCTIONS SHOULD BE READ CAREFULLY AND RETAINED FOR FUTURE REFERENCE.

accidentally covered.
NEVER cover or obstruct in any way the air inlet slots at the
front of the heater or the heat outlet slots in the base of the

programme controller, a timer or any other device which
switches on the heater automatically, remember to observe
all safety warnings at all times.

Procedure
The Dimplex WFC 3NB and WFC 3NS have a total loading of 3 kW.
They are fitted with two control knobs and a pilot light. The air inlet is in
the front panel, and the outlet on the underside.
Release the front cover from the unit by undoing the two screws under the
bottom edge. The upper knob operates a six-position switch, giving a choice of
operating characteristics as follows :
Carefully remove cover by pulling bottom-front forward, and then lift to
release top from retaining slots.
▬Off
Mark screw fixing positions on wall in accordance with the dimensions
shown on the diagram. The unit must be secured to the wall with four
screws through the holes provided. The two upper holes are keyhole
shaped to enable the two upper screws to be positioned first. The unit can
then be hung on these screws while the two lower screws are positioned.
Before finally tightening all four screws, ensure the unit is truly horizontal.
▬1kW of heat, low fan speed.
▬2kW of heat, medium fan speed.
▬3kW of heat, high fan speed.
Fit a 3 core 1.5 square millimetre flexible cord through the cable entry
bush, connect wires to the appropriate terminals and tighten cable clamp.
Alternatively the heater may be connected with conduit through the base
after removing the knockout containing the cable entry bush (see Fig. 4
Wiring Diagram).
▬Fan only, low speed.
▬Fan only, high speed.
The lower knob operates a thermostat which enables the temperature of
the room to be regulated.

electricity supply off if for any reason the appliance overheats.
B. Cut –out 2. Pink 1mm2
C. Selector switch 3. Violet 1mm2If the cut-out has operated because the air flow has been obstructed in
some way, the heater will switch on once the obstruction has been
removed. If the cut-out continues to operate intermittently the heater
should be switched off and a service agent should be called.

the required temperature on the visually graduated scale (see Fig. 2).
The thermostat will monitor continuously the temperature of the air
returning to the inlet grille, and the appropriate heater element(s) will be
selected automatically to achieve or maintain the chosen level efficiently
and economically.

WARNING :
BEFORE UNDERTAKING ANY MAINTENANCE OR CLEANING WORK
ON THE APPLIANCE, IMMEDIATELY DISCONNECT THE
ELECTRICITY SUPPLY EITHER BY SWITCHING OFF AT THE
ADJACENT DOUBLE POLE SWITCH OR BY REMOVING THE PLUG
FROM THE SOCKET.
The outside of the appliance should be wiped over with a soft damp cloth
and then dried. Do not use detergents or abrasives.

Service and Repair
THE INTERNAL CLEANING AND MAINTENANCE WORK SHOULD
ONLY BE UNDERTAKEN BY COMPETENT PERSONS WITH
EXPERIENCE OF REPAIRING DOMESTIC ELECTRICAL APPLIANCES

INVOLVED.
To ensure the appliance operates efficiently, the following maintenance
should be undertaken periodically. The cover should be removed and
refitted as detailed under ‘Procedure’.
Fig. 5
•Fan Blades : These should be cleaned by using the soft brush
attachment of a vacuum cleaner. Care should be taken not to
damage the blades.
•Filter : The filter can be removed completely for cleaning, but
generally provided this is cleaned frequently as detailed above, this
should not be necessary. Where removal of filter is required for
cleaning, the filter retaining wires can be removed, allowing the mesh
and the filter to be taken out (see Fig. 5).
•General : With the cover removed, opportunity should be taken to
remove any accumulations of dust from within the unit.
•Bearings : Fan and motor bearings should be given one or two (not
more) drops of low viscosity oil (e.g. sewing machine oil)
approximately every 12 months.
