10. 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.
11. To avoid damage to the case when soldered fittings are used, pre-solder the
pipework and fittings before connecting them to the inlet stub.
12. Supply pipework MUST be flushed to clear debris before connecting the appliance.
13. The appliance is fitted with a 1/2" BSP male outlet thread, to accept a Mira Zest
shower hose.
14. 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.
15. A hose retaining ring 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 ring
should meet the majority of user
requirements for shower installations
with flexible outlet fittings. However,
there will be occasions when the hose
retaining ring 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 0.1 bar (10 kPa).
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.
16. Avoid layouts where the shower hose will be sharply kinked. This may reduce
the life of the hose.
