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 ‘N’ or Black. Connect Brown wire to plug terminal
marked ‘L’ or Red.
Refit cover, first hooking top over the unit and then securing 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. 3.

Operation
The WFE3TN has a total loading of 3KW. It
incorporates a sensitive electronic thermostat,
and a programmable 7 day timer. To switch the
appliance ON, it should be connected to the
electricity supply and switched on at the ON/
OFF double pole switch – see ‘b’ in Fig. 4.
Thermostat (see ‘a’ in Fig. 4)
The thermostat scale is calibrated in 1°C
divisions with a temperature range from 5°C to
30°C.
To control the room temperature, set the mark
on the thermostat knob to the required
temperature on the scale. The electronic sensor
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. Two
pilot lights (see ‘d’ in Fig. 4) indicate when one
or both heating elements are in operation. An
additional pilot light on the digital timer will
illuminate when the timer is in ‘Manual On’ mode
or in ‘Auto’ mode with a program running. The
extra sensitivity of the electronic thermostat
ensures that the room temperature is maintained
within close tolerances efficiently and
economically.

Key Lock
T o lock the keypad press ENTER and
MODE simultaneously. The key
symbol will appear on the screen
when the keypad is locked – see
Fig. 16. T o unlock the keypad repeat
the action above.
Note- Timer Memory Back Up Batteries – Once the heater has
been left plugged in with the socket switched on for at least 72 hours
the timer’s memory back up batteries will be fully charged.
Once the timer batteries are fully charged, if there is a power cut out or
if the heater is disconnected form the mains from less than six months,
then the timer will continue to keep time, and the settings in the memory
will remain intact.
If however the timer batteries have not been charged fully, or if the
heater is deprived of power for longer than six months, then the time
and programme settings are likely to be lost and you may therefore need
to reset the time and programme before using the ‘AUTO’ MODE again.
General Cleaning
WARNING : BEFORE UNDERTAKING ANY MAINTENANCE OR
CLEANING WORK ON THE APPLIANCE, IMMEDIA TEL Y 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.
The filter should be cleaned by gently passing the soft brush attachment
of a vacuum cleaner over the front grille (see ‘d’ in Fig. 17).
Service and Repair
THE INTERNAL CLEANING AND MAINTENANCE WORK SHOULD ONL Y
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 (see ‘c’ in Fig. 17) : 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 (see ‘a’ in Fig. 17) can be removed,
allowing the mesh (see ‘b’ in Fig. 17) 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.
