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

with the heater is avoided and objects cannot be
inserted into the product.

WARNING: 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 i s
present.

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 double­pole 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

marked E or
wire to plug terminal marked N or Black. Connect Brown wire
to plug terminal marked L or 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 Fig. 2).

Operation

Fig. 4 - Controls & Control

Panel Layout

The Dimplex WFC 3NB and WFC 3NS have a total loading of
3Kw. 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.
The upper knob 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 operates a thermostat which enables the
temperature of the room to be regulated.

The pilot light indicates when the appliance is connected to the
electricity supply.

Thermal Safety Cut-out

In the event that the appliance overheats, the cut-out switches
the heater off automatically. To bring the heater back into
operation, remove the cause of overheating, then turn Off the
electrical supply to the heater for a few minutes. When the
heater has cooled sufficiently reconnect 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
