INSTALLATION / FINAL ASSEMBLY AND COMMISSIONING

Riser rail

1 7

Part the mounting bracket assembly so that the fixing plate is separate from the cover. Establish the best position for the riser rail, and mark the wall for the lower mounting bracket.

Make allowances for the tallest person likely to use the shower regularly.

Insert the rail into the bottom and top brackets and screw the upper mounting bracket in place. Clip the end caps onto the mounting brackets.

The cable should be routed to the shower unit from either the top, bottom or back of the shower unit. This cable should be hidden from view.

Connect the brown live wire to the terminal marked L

Connect the blue neutral wire to the terminal marked N

2)	Fit the flexible hose to the shower unit
	and remove the showerhead.
3)	Turn the temperature control knob at
	the bottom of the unit fully
	anti-clockwise.
4)	Turn on the power at the isolating
	switch.

When drilling through tiles use a suitable glass or tile drill of 6mm diameter to drill through the tile only. Use a no 10/5.5mm masonry drill to make a hole 35mm deep, and fit the wall plug. (NB some

wall constructions may require the use of different types of wall fixings to those supplied). Screw the lower bracket base to the wall.

3

Locate the crimped end of the riser rail (Figure 4) into the mounting bracket, then fit the upper bracket to the rail. Ensure the rail is vertical, then mark the wall for the fixing.

4

NOTE if it is necessary to shorten the rail, use a junior hacksaw to cut the excess material from the plain end of the rail (the uncrimped end).

5

Insert the end pieces of the height adjuster into the body section matching the letters A and B (moulded into the ends of each piece) and twist so the pieces lock together.

6

With the shower head holder in the upright position (widest

opening at the top) and the lever in the open position, slide

the assembly onto the rail. Tighten the height adjuster to

the rail by twisting the lever.

Electrical

Switch off the water supply at the isolating valve before connecting the wiring to the unit.

The shower unit must be permanently connected to the electricity supply, direct from the consumer unit via a double pole linked switch with a minimum contact gap of 3mm.

It is recommended that the switch be a cord operated type with neon on/off indicator, otherwise the switch should be readily accessible, clearly identifiable and out of reach of any person using the shower. The wiring to the switch must be done without the use of a plug or socket outlet.

The cable used must be of a diameter suitable for the power rating of the shower selected. The table below may be used as a guide to the cable requirements. If in doubt consult a qualified electrician.

kW rating	Minimum	Fuse rating	Max cable length
Isolating	switch (Amps)	(Amps)	Consumer unit to
			shower (m)
			6mm cable	10mm cable
7.5	40	40	27	44
8.5	40	40	23	38
9.5	40	40	21	32
10.5	45	45	18	30

Connect the yellow and green earth wire to the terminal marked E on the backplate.

IMPORTANT – ensure the terminal block screws are fully tightened and that no insulation enters the terminal block, preventing a good electrical connection.

To conform to IEE regulations the earth continuity conductor of the electrical installation must be effectively connected to all exposed metal parts of other appliances and services in the room in which the shower unit is installed.

WARNING! Do not attempt to operate the shower unit until the installation is fully complete.

SECTION 3

Final assembly and commissioning

With the unit wired and plumbed correctly the front cover may now be refitted.

1)Place the cover lightly over the shower unit and turn the knobs so that they engage correctly with the spindles. The front cover may then be pressed lightly into place and secured using the two fixing screws.

5) Start the shower by pressing the cold

power selector button. The water

should now begin to flow through the

shower.

Warning do not attempt to select any other

setting other than Cold at this stage.

6)Once a steady stream of water is achieved from the outlet of the shower unit stop the shower by pressing the STOP button.

7)Pass the hose through the hole in the soap dish and refit the shower head.

8)Fit the handset into the height adjuster and clip the soap dish onto the riser rail.

The unit is now ready for commissioning.

Commissioning the shower

Important: The shower unit must be full of water before power (heat) settings are used.

1)With the water supply to the unit turned on, turn the bottom temperature control knob anti-clockwise to the full cold position. No water should exit the shower either from the handset or from any other part of the shower unit.
