Mira Vie Installation And User Manual page 13

10. Do not install the appliance in a position where it may become frozen. The
shower unit must not be fitted where it may be exposed to freezing conditions.
The shower unit must not be used if you suspect it may be frozen.
11. We recommend that a non-restrictive (free-flowing) isolating valve is fitted in
the cold water supply pipe to allow the complete maintenance of the appliance.
Do not use a valve with a loose washer plate (jumper) as this can lead to a build
up of static pressure.
12. To avoid damage to the case when soldered fittings are used, pre-solder the
pipework and fittings before connecting them to the inlet stub.
13. Supply pipework MUST be flushed to clear debris before connecting the
appliance.
14. The appliance is fitted with a 1/2" BSP male outlet thread, to accept an Mira Vie
shower hose.
15. When installed in very hard water areas (above 200 ppm temporary hardness)
your installer may advise the installation of a water treatment device, to reduce
the effects of limescale formation. Appliance malfunction due to excessive
limescale formation is not covered by the manufacturer's guarantee. Your local
water company will be able to advise on the hardness of water in your area.
16. A hose retaining soap dish is supplied to
prevent the handset from dropping below
the spillover level of the bath or shower,
which could lead to contamination from
back-siphonage.
The supplied hose retaining soap dish should
meet the majority of user requirements
for shower installations with flexible outlet
fittings. However, there will be occasions
when the hose retaining soap dish will not
provide a suitable solution. In these instances
an outlet double checkvalve must be fitted.
This will increase the required supply
pressure typically by 10 kPa (0.1 bar).
Double checkvalves, fitted in the inlet supply
to the appliance, cause a pressure build-up,
which could exceed the maximum static inlet
pressure for the appliance.
17. Avoid layouts where the shower hose will be sharply kinked. This may reduce
the life of the hose.
18. If you experience any difficulty with the installation or operation of your new
shower, then please refer to 'Fault Diagnosis', before contacting Mira Showers.
Our contact details can be found on the back cover of this guide.
