Installation Requirements
Plumbing
1. The plumbing installation must comply with all national or local water regulations
and all relevant building regulations, or any particular regulation or practice
specied by the local water supply company.
2. DO NOT use sealing compounds on any pipe tting or joints.
3. DO NOT install the product in a position in which service access is limited.
4. Decide on a suitable position for the shower (minimum distance of 200 mm from
the ceiling to allow for cover t and removal).
5. The position of the shower and shower ttings must provide a minimum gap of
25 mm between the showerhead and the spill over level of any bath, shower
tray or basin and a minimum gap of 30 mm between the showerhead and the
spill over level of any toilet, bidet or other appliance with a Fluid Category 5
backow risk (see diagram on page 10).
6. The shower is suitable for installation within the shower area and is tted with
a pressure relief valve. It must be positioned over a water catchment area with
the controls at a convenient height for the user.
7. The shower must be tted to a waterproof at and even wall surface.
8. DO NOT t the shower to the wall and tile up to the case.
9. DO NOT seal the gap between the shower and the wall surface.
10. The showerhead should be positioned so that it discharges down the centre
line of the bath or across the opening of a shower cubicle.
11. The showerhead must be directed away from the shower unit, during normal
use the showerhead must not spray directly on to the shower unit.
12. DO NOT apply excessive force to plumbing connections; always provide
mechanical support when making plumbing connections. Any soldered joints
should be made before connecting the shower.
13. This shower is not designed to be plumbed directly from the rear. For rear-entry
supply, add an elbow to the supply pipe and connect as a rising or a falling
supply.
14. If pipework and/or electrical cables enter the shower from the rear through a
hole in the wall provision must be made to prevent water ingress back into the
wall structure.
15. Only use the inlet connector supplied with the shower. DO NOT use any other
type of tting.
16. A full bore/non restrictive servicing valve must be tted in a readily accessible
position adjacent to the shower to facilitate maintenance of the shower.
DO NOT use a valve with a loose washer plate (jumper) as this can lead to a
build up of static pressure.

17. A water treatment device should be installed where the water hardness may
exceed 200 ppm. Malfunctions caused by excessive limescale formation are
not covered by this shower’s guarantee (see back page for details).
18. The installation must not cause the hose to be sharply kinked during normal
use.
19. DO NOT perform the electrical installation until the plumbing has been completed
and checked for leaks.
Hose retaining ring tted and shower ttings xed at a suitable height
preventing dirty water backow
Note: There will be occasions when the hose retaining ring will not provide
a suitable solution for Fluid Category 3 installations, in these instances
an outlet double check valve must be tted, this will increase the required
supply pressure typically by 10kPa (0.1 bar). Double check valves tted in
the inlet supply to the appliance cause a pressure build up, which a󰀨ect
the maximum static inlet pressure for the appliance and must not be tted.
For Fluid category 5 double check valves are not suitable.

Determine the direction and route
of the incoming water supply:
falling (entering the shower from
the top), or rising (entering the
shower from the bottom).
Note: - DO NOT use an incoming
supply entering the shower directly
from the back. Add an elbow to the
supply pipe and connect it as a
rising or falling supply.
Swivel the inlet connector assembly
to suit. Remove the inlet blanking
cap. Avoid trapping the green earth
bonding wire.
Warning! Turn o󰀨 the electrical and water supplies before proceeding with
the installation of the shower. The electricity must be turned o󰀨 at the mains
and the appropriate circuit fuse removed, if applicable.

Three case inserts are supplied with the Mira Escape, so that they can be trimmed
to suit the supplies entering the product. Before tting the cover, make sure that the
case inserts are tted.
Thoroughly ush the mains-fed cold water supply pipe. The supply must be
clean and free from debris BEFORE connecting the Mira Escape.
To ush the pipework, turn on the water supply and drain a minimum of 10 litres
(2 gallons) of water into a bucket or catchment area. Turn o󰀨 the water supply.
An installation template is supplied to help you install the Mira Escape.
Put the installation template on the wall and mark through the positions of the xing
holes. Make sure that the position of these holes do not come in line with any buried
cables or pipework. Make sure that su󰀩cient electrical supply cable is available for
connection to the terminal block.
Drill and plug the top two xing holes. Secure the Mira Escape to the wall with
appropriate screws. Drill the bottom xing hole with the product in place. Alternative
xings (not supplied) may be necessary for some wall structures. Avoid drilling into
any supply cable/pipe.
Install the mains-fed cold water supply
pipe. Do not overtighten.
Feed cable into Case. Fit Earth sleeve (not
supplied) and strip insulation.
Do not twist cable cores.
Important! Make sure
that the inlet earth wire is
routed as shown. Failure
to do so may cause
product malfunction.

How Your Electric Shower Works

19 1060688-W2-P
The shower's top priority is to keep the desired water temperature constant. Electric
showers with thermostatic control are able to keep a stable temperature across the
range from hot to cold, whilst also dealing with uctuations in electrical and water
supplies. As a result, there is a temperature limit the shower cannot go beyond. For
safety, this temperature is factory set and cannot be adjusted to make the shower
hotter or colder.
