⚠️ WARNING: THIS HEATER MUST NOT BE LOCATED IMMEDIATELY ABOVE OR 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.

Keep combustible materials such as drapes and other furnishings clear from the front of the heater. Do not use the heater to dry your laundry.

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.

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.

If you use this heater in conjunction with a thermal control, a programme controller, a timer or any other device which switches on the heater automatically, remember to observe all safety warnings at all times.

Do not use where excessive dust or moisture is present.

Installation

Before undertaking installation work, ensure the electricity supply is disconnected from any relevant fixed wiring.

The 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 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 using a plug-top:

• 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.

Fixing Dimensions and Procedure

Fig. 5: This diagram shows the fixing dimensions for wall mounting. The unit has a width of 571mm and a depth of 510mm. Key mounting hole positions are indicated. A cable or conduit entry is located at the bottom.

Procedure:

1. Release the front cover from the unit by undoing the two screws under the bottom edge.
2. Carefully remove the cover by pulling the bottom-front forward, and then lift to release the top from retaining slots.
3. Mark screw fixing positions on the wall in accordance with the dimensions shown on the diagram in Fig. 5. The unit must be secured to the wall with four screws through the holes provided.
4. 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.
5. Before finally tightening all four screws, ensure the unit is truly horizontal.
6. Fit a 3 core 1.5 square millimetre flexible cord through the cable entry bush, connect wires to the appropriate terminals and tighten the cable clamp. Alternatively, the heater may be connected with conduit through the base after removing the knockout containing the cable entry bush (see Fig. 6 Wiring Diagram).

Operation

The WFE3TN has a total loading of 3KW. It incorporates a sensitive electronic thermostat and a programmable 24-hour timer. To switch the appliance ON, it should be connected to the electricity supply and switched on at the double pole switch marked OFF – ON.

Initial Operation

For initial use, plug the appliance into a regular household power point and turn the power on.

Clear all current information by pressing the R (Reset) button with a sharp object such as a pencil. The timer is now ready to be set up for use.

Fig. 2: Controls & Control Panel Layout: This diagram shows the control panel featuring Pilot Lights, a Digital Timer display, a Thermostat Knob, and an On/Off Switch.

Thermostat

The thermostat scale is calibrated in 1°C divisions with a temperature range from 5°C to 30°C.

Fig. 3: Thermostat Knob: Depicts the thermostat control knob.

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 indicate when one or both heating elements are in operation. The extra sensitivity of the electronic thermostat ensures that the room temperature is maintained within close tolerances efficiently and economically.

Digital Timer Operation

IMPORTANT: DO NOT plug in the appliance where the load exceeds 16 Amp.

The timer has a total of 8 ON/OFF programs. MANUAL ON/AUTO/MANUAL OFF settings can be made easily. Either 12 or 24-hour modes can be used. The Summertime function is very useful for areas with summertime systems. 16 combinations of days or blocks of days are available for this timer.

General Cleaning

⚠️ 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.

The filter should be cleaned by gently passing the soft brush attachment of a vacuum cleaner over the front grille.

Fig. 7: Filter Components: This diagram shows the filter assembly, including the Filter Retaining Wires, Mesh, Filter, and Air Inlet Grille.

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 can be removed completely for cleaning, but generally, provided this is cleaned frequently as detailed above, this should not be necessary. Where removal of the filter is required for cleaning, the filter retaining wires can be removed, allowing the mesh and the filter to be taken out (see Fig. 7).
• 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.
