FOR THE USER:

WARNING: DO NOT operate shower if frozen, or suspected of being frozen.

It must thaw out before using.

DO NOT operate the unit if the showerhead or spray hose becomes
damaged.

DO NOT restrict flow out of shower by placing showerhead in direct contact
with your body or ther solid object.

WARNING: the outlet of the shower acts as a vent and must not be
connected to anything other than the flexible shower hose and handset
supplied or approved by the manufacturer.

DO NOT operate the shower if water ceases to flow during use or if water
has entered inside the unit because of an incorrectly fitted cover.

DO NOT place items such as soap, shampoo or other such bottles on top of
the unit as liquid could leak through the joint between the cover and back
plate and damage the sealing rubber.

The shower spray head MUST be cleaned regularly to remove scale and
debris. The frequency of the cleaning will vary according to the local water
quality. If the water outlet temperature becomes hot and you are unable to
obtain cooler water, immediately check the shower handset for blockage.

FOR THE INSTALLER:

MAINS SERVICE CONNECTIONS: The shower unit is supplied for right hand

mains water and electrical connection.

IMPORTANT: To comply with water regulations, building regulations or any specific
local water company regulations and in accordance with BS EN 806 a double check
valve should be fitted where it is possible that the shower head may come into
contact with used water, for example in the bath or a shower tray.

IMPORTANT: Check that there are no hidden cables or pipes before drilling
holes for the wall plugs. Choose a flat piece of wall to avoid the possibility of
distorting the back plate and making the front cover a poor fit. Exercise great care
when using power tools near water. The use of a residual current device (RDC) is
recommended.

IMPORTANT: Before connecting the water supply to the shower
unit the water supply pipe should be flushed out to remove all debris. After
flushing the pipe work make the connection to shower inlet and ensure the
shower is positioned squarely on the wall and all fixing screws are tightened.

Plan your installation carefully. Check on the nearest
and most accessible rising main water supply, this
may be beneath the bath or in the loft, where it feeds
the water storage tank. Use only the cold rising
water main.

Avoid connecting the shower unit if possible where
it will be affected by water drawn off by another
appliance.

For example from the mains feed to the toilet as this
may cause a drop in pressure to a level that is too low
for the shower unit to work correctly.

A WRAS (Water Regulations Advice Scheme) listed
isolating valve must be fitted between the rising main
and the unit to comply with water regulations and to
allow for routine maintenance and servicing.
