IMPORTANT SAFETY ADVICE
WARNING – THIS APPLIANCE MUST NOT BE USED IN A BATHROOM.
WARNING – DO NOT USE THIS HEATER IN THE IMMEDIATE
SURROUNDINGS OF A BATH, A SHOWER OR A SWIMMING POOL.
WARNING – THIS HEATER MUST NOT BE LOCATED IMMEDIATELY BELOW
A FIXED SOCKET OUTLET.
DO NOT USE THE HEATER UNTIL IT IS WALL MOUNTED CORRECTLY.
The heater carries a warning ‘Do Not Cover’ to alert the user to the risk
of overheating that exists if the heater is 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 heater.
Keep combustible materials such as drapes and other furnishings clear
from the front of the heater. Do not use heater to dry your laundry.
This appliance is not intended for use by children or other persons
without assistance or supervision if their physical, sensory or mental
capabilities prevent them from using it safely. Children should be
supervised to ensure that they do not play with the appliance.
If young children, the aged, or infirm are likely to be left in the vicinity
of the heater, we advise that adequate precautions should be taken. We
recommend that a guard be fitted to ensure contact with the heater is
avoided and objects cannot be inserted into the product.
Caution: In order to avoid a hazard due to inadvertent resetting of the
thermal cut-out, this appliance must not be supplied through an external
switching device, such as a timer, or connected to a circuit that is
regularly switched on and off by the utility. Do not use where excessive
dust or moisture is present.
For further information, please contact our guard supplier direct on Tel.
No. 01603 667957, or in the case of difficulty or for further advice contact
the Customer Helpline.
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 fixed 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.
Procedure
Release the front cover from the unit by undoing the two screws under the bottom
edge.
Carefully remove cover by pulling bottom-front forward, and then lift to release
top from retaining slots.
Mark screw fixing positions on wall in accordance with the dimensions shown on the
diagram in Fig 2. 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.
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 ‘A’ in Fig. 2).
Operation
The Dimplex WFC 3NB and WFC 3NS have a total loading of 3Kw. They are
fitted with two control knobs (see ‘X’ and ‘Z’ on Fig. 4)and a pilot light (see ‘Y’ on
Fig.4). The air inlet is in the front panel, and the outlet on the underside.
The upper knob ‘X’ operates a six-position switch, giving a choice of operating
characteristics as follows :
Off
1Kw of heat, low fan speed
2Kw of heat, medium fan speed
3Kw of heat, high fan speed
Fan only, low speed
Fan only, high speed
The lower knob (see ‘Z’ on Fig. 4) operates a thermostat which enables the
temperature of the room to be regulated.
The pilot light (see ‘Y’ on Fig. 4) indicates when the appliance is connected to the
electricity supply.
Additionally, a cut-out is incorporated in the unit which will switch the electricity
supply off if for any reason the appliance overheats.
To control the room temperature, set the mark on the thermostat knob to the
required temperature on the visually graduated scale (see ‘Z’ on Fig. 4). The
thermostat will monitor continuously the temperature of the air returning to the inlet
grille, and the heater element(s) selected will achieve or maintain the chosen
temperature level efficiently and economically.
When running Fan only modes, rotate thermostat knob ‘Z’ fully clockwise to
ensure continuous cool air.
Thermal Safety Cut-out
For your safety, this appliance has been fitted with thermal cut-out. In the event
that the product overheats, the cut-out switches the heat off automatically.
To bring the heat back into operation, remove the cause of the overheating, then
unplug or turn off the electrical supply to the heater for up to 10 minutes.
When the heater has cooled sufficiently, re-connect and switch on the heater.If the
cut-out operates repeatedly, contact your supplier.
To control the room temperature, set the mark on the thermostat knob to the
required temperature on the visually graduated scale (see Fig. 4). The thermostat
will monitor continuously the temperature of the air returning to the inlet grille, and
the heater element(s) selected will achieve or maintain the chosen temperature
level efficiently and economically.
When running Fan only modes, rotate thermostat knob to ‘max.’ position to ensure
continuous cool air

Service and Repair
THE INTERNAL CLEANING AND MAINTENANCE WORK SHOULD ONLY BE
UNDERTAKEN BY COMPETENT PERSONS WITH EXPERIENCE OF REPAIRING
DOMESTIC ELECTRICAL APPLIANCES AND IN FULL KNOWLEDGE OF THE
POSSIBLE HAZARDS 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’.
·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 (see ‘c’ - Fig. 5) 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 (see ‘a’ - Fig. 5) can be removed, allowing the mesh (see ‘b’ - Fig. 5) and
the filter to be taken out .
·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.
