Refer to section: 'Important Safety Information' first.

1. Do not use sealing compounds on any pipe fitting or joints.

2. To avoid damage to the case when soldered fittings are used, pre-solder the

pipework and fittings before connecting them to the inlet connector assembly.

3. Never fit the appliance to hot water supplies or to gravity systems of any

description. Only fit the product to a mains cold water pipe.

4. If the pressure exceeds the maximum specified then a drop tight pressure

reducing valve (PRV) must be fitted. This should be sited as close to the incoming

mains stopcock and ideally set to 3.5 bar.

5. Avoid layouts where the shower hose will be sharply kinked. This may reduce

the life of the hose.

6. Supply pipework MUST be flushed to clear debris before connecting the

appliance. Debris will reduce the performance of the shower and may damage

the product. Avoid running the pipework through excessively hot or cold areas

such as hot loft spaces, airing cupboards, or in close proximity to hot water pipes.

If this cannot be avoided, we recommend insulating the pipes.

7. The shower must be fitted onto a tiled or sealed finished surface i.e. on top of

tiles. DO NOT tile up to the sides of the shower or use a sealant around the

case. Failure to do this may cause appliance failure. 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.

8. We recommend that a non-restrictive (free flowing) isolating valve is fitted in the

cold water supply pipe to allow maintenance of the appliance.

9. When installed in very hard water areas (above 200ppm temporary hardness)

your installer may advise the installation of a water treatment device, to reduce

the effects of limescale formation. Any malfunction due to limescale is not covered

by the manufacturer's guarantee. Your local water company will be able to advise

the hardness of water in your area.

10. Wall fixings are supplied for solid wall structures. For other wall structures such

as wall panels alternative fixings may be required. A minimum of 2 fixing screws

must be used.

11. The position of the shower and shower fittings must provide a minimum gap of

25 mm between the showerhead and the spill over level of any bath, shower tray

or basin and a minimum gap of 30 mm between the showerhead and the spill

over level of any toilet, bidet or other appliance with a Fluid Category 5 backflow

risk.
