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).

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
