INSTALLATION AND WIRING INSTRUCTIONS SPECIFICATIONS Power Supply : 220/240Vac, 50/Hz Switch Action : 1 x SPST, Type 1B Switch Rating : 220/240Vac, 50/60Hz, 6(2)A. Timing Accuracy : ± 1 min./month Enclosure Rating : IP20 Pollution Situation : Degree 2 Max. Ambient Temp. : 55°C Designed to meet BS EN60730-2-7 Dimensions : 112mm wide, 135mm high, 69mm deep Rated Impulse voltage : 2.5kV Ball Pressure Test : 75°C 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 disconnect in accordance with BS EN60730-1, e.g. via a plug and unswitched 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. Cut a cable aperture in theWiring Cover if necessary; replace theWiring 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) Check that all positions of the Selector Switch andTappets operate 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 off and is in a dusty atmosphere, protect the pre-selector wheel by re-affixing the protective tape. IMPORTANT: Remove tape prior to putting unit into service.

NOTE: Ease of installation can be achieved by using the Danfoss Randall Wiring Centre which is obtainable from most Builders Merchants and Distributors. IF A WIRING CENTRE IS USED, follow the installation instructions included with the unit and not the wiring diagrams shown on this page. Danfoss Randall can accept no responsibility for possible errors in catalogues, brochures and other printed material. Danfoss Randall reserves the right to alter its products without notice. This also applies to products already on order provided that such alterations can be made without subsequent changes being necessary in specifications already agreed.
