3.6. Using a spirit level, position the
Mira Extreme on the wall and
mark through the three fixing
points.
Tip! Special consideration should
be given to the strength of the
fixing arrangements when
installing on to a dry lined, stud
partition or dry partition wall
structure. Installers may wish to
obtain alternative proprietary cavity
fixings, or choose other options
such as fabricating rear supports
using wooden blocks; however,
these methods of fixing are beyond
the scope of this guide.
Warning! Ensure the marked
fixing points are not inline with
buried cables and pipes before
drilling.
3.7. Drill 9.5 mm holes and fit the
rubber wall plugs supplied.
3.8. Cut away and trim the thinned
section in the top of the case to
allow the electrical supply cable to
run down cable channel in the
back of the case.
3.9. Run the electrical supply cable in
surface mounted miniature
trunking (not supplied). Allow
sufficient cable to connect to the
Mira Extreme terminal block
(approximately 275 mm). Strip
back approximately 30 mm of outer
cable insulation.
3.10. Hot and cold inlet supply
connections as marked are:
Hot – Left Cold – Right
Note! Supply connections must
not be connected in reverse.
