- Ensure the switch is in the OFF position
- Unscrew the cover screws & remove the cover
- For easy wiring the switch can be removed from the base by simply removing the two fixing screws. Once wiring is com- pleted replace the switch and secure in position with the fixing screws (taking care not to over tighten - recommended tightening torque 0.5Nm)
- After wiring ensure the profile orientation of the actuating spindle & knob shaft are in the same position
- Replace the cover & take care not to overtighten the screws (recommended tightening torque 0.5Nm)
- Do not install using power driven screwdrivers Note: There is no need to remove the switch handle in order to remove the cover.
