Planning the installation

Product Positioning Guide

The shower should be located in a position where walls are protected from water and sufficient drainage is provided.

1)Consideration should be given to the location of the nearest cold mains water supply and the routing of this to the shower. The shower will accept a mains supply from the bottom, back or top of the unit. Remove the appropriate plastic plate from the back plate before commencing installation.

2)Avoid connecting the shower unit where it will be affected by water drawn off by other appliances, e.g. from the mains feed to the W.C. This may cause a drop in pressure too low for the shower unit to work correctly.

General

1)Fit an isolating valve to the mains water supply so that the shower can be serviced.

2)The shower unit is best placed to the right hand side of the riser rail and placed so that the top of the unit sits alongside the middle to top of the riser rail. This reduces the amount of water falling on the unit.

The top of the riser rail should be sited to coincide with the height of the tallest person using the shower.

Before drilling any holes check that there are no hidden cables or pipes below the surface to be drilled.

To avoid loss of small parts cover any drainage holes.

3)The shower unit should be positioned so that the showerhead cannot be immersed in the bath or shower tray when hanging down.

Where holes are to be drilled into a tiled surface a suitable tile or glass drill bit should be used to make a hole through the tile only. The hole made through the tile should be 0.5mm larger than the hole in the wall.

These installation instructions assume mounting onto a solid masonry wall. For other types of structure please amend the procedure accordingly.

Plumbing

1)Remove the front cover of the shower unit complete with the two control knobs by removing the two screws securing it to the back plate. Remove the ‘trim plate’ at the bottom right-hand side of unit to allow easy access for the plumbing work.

2)Position the shower unit on the wall in the desired place and mark the location of the fixing holes.

3)Determine the direction of the inlet water supply: bottom (rising), top (falling) or back inlet. The shower unit is supplied with a swivelling push-fit inlet elbow. This elbow should be rotated to match the desired direction of water supply entry to the unit. Carefully remove the appropriate plastic break-out from the unit’s back plate so that the mains water supply pipe can be routed into the unit.

4)Carefully drill the holes using a 5.5mm masonry drill (note when drilling though tiles first use a glass or tile drill bit of 6mm diameter to drill a hole through the tile).

5)Insert the plugs provided through the hole in the tile and fix the unit to the wall using the screws supplied. Do not tighten the screws fully at this stage.

6)Turn off the water supply at the isolating stop tap.

7)Bring the mains water supply using 15mm copper or stainless steel pipe to the shower unit so that it enters through the hole in the back plate.

8)Before connecting the shower unit, flush out any debris in the new pipework by connecting a hose to the end of the mains supply pipe and running the mains water until all the debris has cleared.

9) After flushing out, turn off the water supply and connect the pipe to the shower inlet. Having inserted the inlet pipe into the elbow, secure the joint by finger tightening the locking device, rotating in a clockwise direction.

10)Make sure that the shower unit is positioned squarely on the wall and tighten the fixing screws. Tighten all plumbing joints and turn on the water supply to check for leaks. With the unit firmly fixed to the wall and the pipework free from leaks, dry the shower area in preparation for the electrical installation.
