Setting the 24 Hour Dial
1.
Hold dial firmly and turn knob H clockwise until levers L (Fig. 2) are easily movable.
Set levers to operating times required. Re-tighten knob H.
2.
Turn dial in direction of arrow until pointer P marked ‘time’ indicates the time of day at the moment of setting.
e.g. Fig. 2 (24 hour dial model) shows dial set for 6 a.m.
3.
Each small division represents
1
/
4
of an hour.
4.
Screw B should only be unscrewed if it is necessary to remove dial.
5.
If dial is removed, when replacing ensure that hub below dial engages with cross-pin on spindle.
6.
The accuracy to which the dial can be set is ± 3 minutes.

Day Omitting Device (Fig. 4) prevents ‘on’ operations (or in some models ‘off’ operations) occurring on any chosen
day or days of week.
2.
To omit operations on any particular day, turn inset 1 clockwise for that day, with screwdriver, until arrowhead
points outwards. For change-over switches with levers marked ‘A’ and ‘B’, this device omits ‘B’ lever operations.

Setting Day Omitting Device (when fitted)
Early Operation Device (when fitted)
Note:
Ensure dial is showing the correct time, then note position of lever L
(Fig. 2) which turns black disc D (Fig. 4) once every revolution on dial.
If this lever has passed the disc, then turn the disc so that the current
day is set to the arrow marked ‘day’. If, however, lever has not
reached disc, then set day preceding current day on disc to arrow.
Note:
Day lever E (Fig. 5) in conjunction with special hinged lever fitted to
the dial,enable a particular switching operation to be made at an
earlier pre-set time on any one day of the week.
