1. The Mira Zest 7.5 kW and 8.5 kW electric showers are designed to operate with
a
minimum maintained inlet pressure of 0.7 bar (70 kPa) up to a maximum
static inlet pressure of 10 bar (1000 kPa) .
2. The appliance is normally connected to the cold water mains-fed supply. However,
the water supply can be taken from a cold water storage cistern, provided there
is a minimum maintained inlet head of water of 7 metres (the vertical distance
from the base of the cold water storage cistern to the shower fitting handset). To
reduce pressure losses and fluctuations, the cistern-fed water supply must be
independent from other supply draw-offs, and should avoid long horizontal pipe
runs and use swept bends rather than 90° elbows. For further advice please
refer to the back cover of this guide for Mira Showers contact telephone and fax
numbers.
3. The appliance is suitable for installation within the shower area. It is fitted with a
pressure relief device and must be positioned over a water catchment area with
the controls at a convenient height for the user. The shower fitting should be
positioned so that it discharges down the centre line of the bath, or across the
opening of a shower cubicle, and must be directed away from the appliance.
4. The appliance is fitted with an inlet connector assembly that is designed to accept
plumbing supplies from the top or bottom. The water supply can be fed with
15 mm pipe or 10 mm microbore pipe, suitably adapted into the inlet connector
assembly. If 10 mm microbore is used, then an allowance for increased pressure
loss must be made to ensure that the minimum maintained inlet pressure is
achieved.
5. Do not fit the appliance to the wall and tile up to the case. The appliance must be
fitted onto a finished flat and even wall surface. Otherwise, difficulty may be
encountered when fitting the cover, and subsequent operation of the unit could
be impaired (small pillars moulded on to the back of the case allow air circulation).
6. Use only the inlet connector assembly supplied with the appliance. Do not use
any other types of fitting.
7. Refrain from applying excessive force when making any connections. Always
provide mechanical support when making the plumbing connections.
8. This appliance is not designed to be plumbed directly from the rear. For a rear-
entry supply, add an elbow to the supply pipe and connect it as a rising or falling
supply.
9. 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.
