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 plug terminal marked E or iii1 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 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. Fixing dimensions Operation 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). Wiring Diagram CAS LE CLAMP 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 : o — Off 1 — 1Kw of heat, low fan speed. II — 2Kw of heat, medium fan speed III — 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 Fig. 3 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. 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 Fig. 5 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.
