d. Install bulb:
1. Remove the lamp cover screws retaining front glass frame (See Fig. 9) and swing
the glass frame away from the fl oodlight cover.
2. Check that the bulb and fi tting contacts are all clean, ensuring that you hold the
bulb with a clean dry cloth during this and subsequent procedures.
3. Locate one of the bulb contacts onto one of the fi tting contacts and push back
the contact spring at the other end inserting the bulb contact into its fi tting
contact. check that the bulb contacts at each end are properly located and that
there is reasonable pressure on the bulb contacts. (See Fig. 10).
4. Tighten the fl oodlight cover screws fi rmly to ensure weatherproof rating.
e. Make backplate holes and cable up:
Decide which of the four 20mm dia. cable entry holes on the back plate you wish to
use (there are 2 rear entry and 2 bottom entry).
if you wish to use additional lighting a second entry point will be required (a manual
override switch can be accommodated by a single entry of 4 core cable). Firstly cut
undersize holes as required in the blind grommets supplied. This way sealing against
moisture infl ux is maintained. Then score around the outside edge of the circular
groove marking the hole with a sharp knife and gently tap out the centre. Do the same
to the second entry point if necessary and fi t the grommet(s) supplied and push the
cable(s) in to give suffi cient length to make a connection for all the cable wires.
f. Fix backplate:
Fix the backplate onto the wall with the large pan head screws supplied using
wall plugs if necessary (See Fig. 11) remembering the cable entry holes are on the
bottom. connect cable wires as necessary. (See Fig. 12).
g. Insert the sensor light onto the backplate (See Fig. 13). Then fi x with the two
small c/sk head screws supplied. (See Fig.14).
