Mira Elite ST Installation Manual page 8

1.3 Use a minimum of 15 mm diameter supply pipework. It should be noted,
however, that on long pipe runs this should be increased to 22 mm (refer to
para 1.17 for guidance). When using flexible plastic pipe it is essential that the
pipe is kept flat and not looped up at any point as this may lead to air build
up
1.4 A non restrictive (free flowing) isolating valve should be fitted into the supply
from the cold water cistern, for maintenance purposes.
1.5 The Elite ST must be fitted to a tiled or sealed finished surface . DO NOT block
the air ventilation gaps around the sides of the unit, either by tiling up to the
sides of the unit or by using a sealant around the case.
Important! This Elite ST is designed to be ventilated. Failure to do this may
cause product failure.
Note! The Mira Elite ST is fitted with a pump motor, and some mechanical
noise can be expected in addition to the noise generated by the spray from
the handset. The type of wall surface will affect the perceived sound levels.
Stud partition and panel walls have a tendency to resonate, whilst solid walls
provide the quietest operation. The tone of the pump motor may change when
the temperature control knob is adjusted. This is quite normal.
1.6 Inlet: 15 mm inlet compression connector is designed to accept plumbing
supplies from the top, bottom or rear.
1.7 Rear entry plumbing is accommodated without the need to recess the 15 mm
inlet compression connector.
shower from the rear through a hole in the wall provision must be made to
prevent water ingress back into the wall
1.8 Swivel the inlet connector assembly to suit (not directly back into the wall).
Avoid trapping the green earth bonding wire.
1.9 Use only the 15 mm inlet compression connector supplied with the Elite ST, do
not use any other types of fitting.
1.10 Outlet: 1/2" BSP male, to accept Mira flexible hose.
1.11 To ensure the case and other components are not put under strain during
installation always provide mechanical support when making plumbing
connections. Upon completion of the installation ensure connections and
back case are not under any stress due to misaligned pipework or electrical
cables.
Note! Excessive force on the pump housing can impair pumping performance.
If pipework and/or electrical cables enter the
structure.
