Shower unit can be mounted either side of riser rail.
Ensure minimum side
and top clearance of
120mm.
For ease of servicing, the unit must always be mounted on the flat surface of tiled walls.
Never tile up to the shower unit.
Do not seal the shower to the wall with silicone sealant.
The flat surface must cover the full width and length of the back plate, otherwise difficulty may arise
when fitting the cover and subsequent operation of the unit may be impaired.
Refer to the illustration below for correct positioning of the shower controls and shower handset.
Position the shower unit vertically.
Check there are no pipes or electrical cables inside the wall before drilling.
The height of the controls is dependent upon the type of installation.
DO NOT obstruct the back and sides of the shower as this will prevent the Pressure Relief Device
(PRD) from operating.
Ensure the shower unit is positioned over a bath, shower tray or wet floor.
The showerhead must be directed away from the shower unit, during normal use the showerhead
must not spray directly on to the shower unit.

Reassembly - Front Cover
Installer
Reassembly - Front Cover
Ensure all connections are correctly inserted before the cover is refitted.
Refit the Front Cover and ensure the cogs on the inner case align.
Only use the supplied screws to secure the front cover. Failure to do so, can cause internal damage to the appliance.
Do not seal the shower to the wall with silicone sealant.
Before re-assembling the front cover, ensure the
dials are turned clockwise and hit their end stops
as shown in the image above.
Attach the front cover to the shower and
ensure all 4 screws are pushed home.

The shower hose retainer (supplied in the accessory pack) should be used. The installation should comply with
Water Regulations and prevent water supply contamination.
To ensure activation of the heating elements, the shower must be connected to a mains cold water supply
with a minimum running pressure of 50kPa (0.7 bar) with a maximum static pressure of 1000kPa (10 bar).
For optimal product performance the recommended minimum dynamic water pressure should be 100kPa
(1 Bar). Dynamic pressure should not fall below 50kPa (0.7 bar) for example when other draw offs are used,
such as a flushing the toilet as this can cause the shower temperature to fluctuate dramatically.
Note: An isolating stop valve must be provided on the cold water feed before connecting to the shower.
We recommend that isolation valves (not supplied) must be fitted as close as is practicable to the water
supply inlets of the shower heater whilst being accessible for maintenance and servicing purposes.
Do not install this appliance in a position where it can freeze.
Never fit the appliance to the hot water supply.
Note: If the stated flow rates are not available, it may not be possible to achieve optimum performance from
the unit throughout the year.
Note: If the Pressure Relief Device fails, then call the installer in first instance as there may be a dynamic
pressure problem.
