ADDITIONAL BACK BOX INSTALLATION NOTES
REMOVING THE BACK BOX KNOCKOUTS
Due care should be taken when removing the knockout(s) on the base of the back box to avoid personal injury. Where necessary use
the appropriate tools and wear the appropriate protective clothing (gloves, eye protection etc.) when removing the knockouts.
1. Before embeding the flush box into the wall or mounting the surface box to the wall it is advised to first remove the knockout(s)
required;
2. Take a flat-head screwdriver and use the flat end to gently ‘tap out’ and apply pressure to the knockout fixing, see
Fig.17
and
Fig.18
;
3. Once the knockout fixing has been removed,
Fig.19
, push down on the knockout, see
Fig.20
;
4. Using a set of pliers grip the end of the knockout and ease it back and forth,
Fig.21
, until the other knockout fixing fatigues and the
knockout breaks away from the base of the back box. If necessary file down and smooth out any rough edges with a metal file;
5. Fit a
Ø20mm
rubber grommet into the knockout hole, see
Fig.22
.

EMBEDING AND FIXING THE BACK BOX TO THE WALL
The flush box and surface back box need to be embeded or fixed to the wall respectively,
therefore a suitable set of masonry screws and wall plugs should be used to do this. It
is recommended that 4x
40mm, Ø3.5mm
self-tapping masonry screws with 4x
40mm,
Ø4mm
nylon type wall plugs are used, see
Fig.23
.
Where necessary use the appropriate power tools and wear the appropriate protective
clothing (gloves, eye protection etc.) when drilling the fixing holes to mount the box
and cutting out the hole in the wall to embed the flush box.
USING SILICON
Whenever using silicon sealant remember to wash your hands after use and always
discard of any excess silicon waste responsibly.
