The unit must be installed by a competent electrician and the installation should conform to I.E.E. Regulations. This unit should be wired via full disconnectinaccordancewithBSEN60730-1,e.g.viaaplugandunswitched socket or double pole switch outlet with neon.

INSTALLATION INSTRUCTIONS

1.Loosen the fixing screw in the base of the unit to release the grey plastic Wiring Cover. Ensure the protective tape over the thumbwheel remains in place.

2.Holding the unit clockface downwards, press firmly in the centre of the wallplate and slide it from the module as shown.

3.Fix the Wallplate/Terminal Block to the wall with countersunk No.8 woodscrews or to a steel box to BS 4662. 1970 or a surface mounting steel or moulded box having centres of 23/8" (60.3mm).

4.Referring to the Wiring Diagrams overleaf, connect the unit as shown. Ensure that terminals 3 and 6 are linked where required (Mains Voltage applications) with insulated cable capable of carrying full load current.

5.Ensure all dust and debris have been cleared away from the area, then plug the module firmly into the wallplate ensuring that the hook at the top of the wallplate engages with the slot at the back of the body. Press the module down until it locates solidly.

6.CutacableapertureintheWiringCoverifnecessary;replacetheWiring Cover, and tighten the fixing screw.

7.Switch on Mains and test for correct operation as follows:

i)Remove protective tape from the pre-selector wheel.

ii)Remove the dial cover and rotate the clock dial two complete revolutions to clear the mechanism.

ii)Checkthatallpositionsofthe Selector SwitchandTappetsoperate correctly. (See instructions in User Booklet.)

8.Replace the dial cover. Finally leave the USER INSTRUCTIONS with the Householder.

9.If the unit is to be left turned o and is in a dusty atmosphere, protect the pre-selector wheel by re-a xing the protective tape.
