Minimum maintained pressure:0.1 bar
Maximum maintained pressure: 5.0 bar
Warning! Exceeding the stated maximum maintained pressure could result in excessive
spray forces and possible damage to the product.
These are the typical ow performance graphs for the Mira Logic adjustable shower ttings
only. There will be an additional pressure loss through the shower control.
Pressure loss = Pressure di󰀨erence between the inlet and outlet of the tting.
Flow Rates
Specications
Installation must be carried out in accordance with these instructions, and must be conducted
by designated, qualied and competent personnel.
1. The hose retaining ring supplied must be used to stop the handset from dropping below
the spill-over level of the bath or shower tray. This will prevent water supply contamination
due to backsiphonage.
2. Installations must comply with UK Water Regulations/ Bye-laws (Scotland), and Building
and Plumbing Regulations in force at the time of installation.
3. When installing the shower ttings in a cubicle, position with the spray pointing across
rather than toward the opening of the cubicle.
4. When installing the shower ttings over a bath, position with the spray pointing down
the centre line of the bath.
5. Avoid layouts where the shower hose will be sharply kinked. This may reduce the life of
the hose.
6. Do not t any form of ow control in the shower outlet.
7. Do not use excessive force when making connections.

Note! For dry lined, stud partition, shower cubicle or laminated panel walls the installer may
wish to obtain alternative proprietary cavity xings. Use of these alternative xings is beyond
the scope of this guide.
Important! If the Logic slide bar replaces an existing Mira slide bar make sure that the
position of the shower control and the shower ttings provide a minimum of 25 mm between
the handset and bath/tray spill-over level. This is necessary to prevent back-siphonage. If
this is not possible then the new slide bar will have to be repositioned.
Mira Logic Exposed Variable Shower Fittings (ev)
Read the section: Installation Requirements before proceeding with the installation.
The slide bar should be positioned to one side of the shower control at a convenient height
for all the family. It should be positioned so that the handset discharges down the centre line
of the bath, or across the opening of the shower cubicle. The handset should be directed
away from the shower control.
1. Decide on a suitable position for the slide
bar avoiding buried cables and pipes.
Make sure that when the hose retaining
ring is placed on the lowest position on
the slide bar there is a minimum of 25 mm
between the handset and bath/tray spill-
over level. This is necessary to prevent
back-siphonage.
2. Important! The slide bar has been
supplied with an applicator tted to one
end (refer to illustration) to assist the
assembly of the slide bar through the
clamp bracket.
With the clamp bracket button FULLY
depressed carefully ease the slide bar
through the hole in the clamp bracket.Take
care not to dislodge the constant friction
mechanism or the friction pad.
3. Release the clamp bracket button.
Remove the applicator from the slide bar
and store in a safe place for future use.
4. Slide the hose retaining ring onto the slide
bar below the clamp bracket.
Installation
8. The minimum pressure required for a satisfactory spray pattern to form, at the handset or
spray head, is 0.1 bar. For a gravity fed shower installation the minimum head of water
required, to accommodate the pressure loss in the pipes and shower control of a typical
installation, is 1.0 metre.
For a pump installation the minimum acceptable vertical distance between the base of
the cold water storage cistern and the shower head to operate the pump’s ow switches,
is typically 0.6 m (600 mm).

5. Make sure that the slots in the slide
bar are aligned with the lugs in the
support and fit the two slide bar
supports to the ends of the slide
bar. Make sure that each support is
pushed rmly home.
Note! If replacing an existing Mira
Slide Bar proceed to instruction 8.
6. Using the assembled slide bar and
supports as a template, mark the
position of the two xing holes using
the centre slot.
Warning! Make sure that there are
no buried cables or pipes in the wall
before drilling.
7. Drill the two 7 mm holes for the
fixing screws and insert the wall
plugs supplied. (Alternatively use
proprietary cavity xings for dry lined,
stud partition, shower cubicle or
laminated panel walls).
8. Fix the bottom slide bar support to the
wall using the screw provided. Make
sure that the screw is fully tightened.
9. Loosely screw the top slide bar
support to the wall. Press rmly down
on the top slide bar support and, while
continuing to apply force, fully tighten
the screw.
10. Fit the end caps to the slide bar
supports.
11. Check the slide bar cannot be
rotated or vertically moved. If there
is movement remove the slide bar
assembly from the wall. Check the
slide bar support lugs are properly
engaged with the slots in the slide bar
and the supports are pushed fully onto
the slide bar ends. Ret the slide bar
assembly.
12. Refer to sections: Handset Installation
to complete the ttings installation.
