Mira Extreme Thermostatic Installation And User Manual page 20

3.4 Drill 9.5 mm holes and fit the rubber
wall plugs supplied.
3.5 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.
3.6 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.
3.7 Hot and cold inlet supply connections
as marked are: Hot - Left, Cold -
Right.
Note! Supply connections must not
be connected in reverse.
Run the hot and cold water supply
pipes at 28 mm centres, make sure
that the pipe ends project into the
Mira Extreme by 30 mm to allow
connection into the inlet manifold.
Caution! Do not use stainless steel
piping for inlet pipework.
Caution! If chrome-plated copper
pipework is used then all traces
of chrome plate must be removed
from the connecting surfaces. If the
chrome is not completely removed
then the inlet manifold collet will fail
to grip the supply pipe and the pipes
will be forced out of the inlet manifold
due to the water supply pressure.
