NB • Control is suitable for fixed wiring only. NB • If the unit is to be surface wired:
- Remove backplate by slackening fixing screw and separate the plate from the timeswitch
- Remove the knock-out from the backplate and the timeswitch
- Screw backplate to wall with counter sunk No. 8. Wood screws, using fixing holes provided.
NB • For socket box mounting:
- Use the centre two holes and fit backplate to box using machine screws
- To ensure clearance for the down flap, ensure that there is a minimum of 4 cm clearance under the unit when mounted
