Combi HP thermostatic mixer shower

Exposed

Note:

The outlet of the shower must not be connected to anything other than the hose and showerhead supplied.

dO nOT use jointing compounds on any pipe fittings for the installation.

dO nOT solder fittings near of the shower unit, as heat transfer can damage components.

Note:

Suitable isolating valves (complying with water Regulations) must be fitted on the hot and cold water supplies to the shower as an independent means of isolating water supplies should maintenance or servicing be necessary.

when connecting pipework avoid using tight

90° elbows. Swept or formed bends will give the best performance.

ImportaNt: The water circuit should be installed such that the flow is not significantly affected by other taps and appliances being operated elsewhere on the premises. Water pressure must not fall below specification of the shower.

Note:

The hot water pipe entry must be on the left.

Rising and falling supplies

Having decided on the position of the shower and direction of pipe entry, complete the pipework to the shower area.

Note:

The final separation between pipe centres needs to be about 153 mm but absolute accuracy is not needed as the inlet elbows are adjustable between 146 mm and 160 mm.

Flush pipework to clear the system of all debris and check for leaks.

ImportaNt: The inlet elbows contain check valves that may be damaged if debris is not flushed through prior to fitting.

where this is not possible refer to the

‘flushing procedure’

on page 20.

clip the pipework to the wall surface so that the pipe centres are 21 mm off the wall.

Offer the valve, together with the inlet elbows, to the pipework. Make sure the inlet elbow grub

Place the valve housing centrally between the two pipes, and mark the two diagonal fixing holes

.

Remove the valve. drill and plug the holes.

(The wall plugs supplied are suitable for most brick walls

— use an appropriate masonry drill, but if wall is plasterboard or a soft building block, you must use suitable wal lplugs and an appropriate drill bit)

.

Fit the nut covers on to the pipes

(fig.)

.

Note:

Slide the pipes into the small diameter end of the nut cover. It will not fit if inserted from the other end.

Slide the inlet nuts and olives onto the pipes, followed by the inlet trims.

Note:

The holes in the inlet trims are offset to allow for adjustable inlet pipe separation widths.

If pipe centre separation is 153 mm or less, then have the short side of the inlet trims between the pipes. If the pipe separation gap is 153 mm or greater, have the long side of the inlet trims between the pipes

(fig.)

. If in any doubt try the cover to see if it fits properly (i.e. no visible gaps between the inlet trims and the cover —

fig.

). If there is a gap

(fig.)

then reverse the trim.

while trying the cover make sure the inlet nuts are sitting in the holes in the inlet trim holes so that the inlet trims are at the correct separation.

Having positioned the inlet trims correctly, refit the valve to the pipework. Make sure the hot inlet port (marked with the letter ‘H’ on the valve housing) is connected to the hot pipework which must be on the left.

Screw to the wall with the two screws supplied

(fig.)

. Tighten the inlet nuts and inlet elbow grub screws.

If installing a tamperproof fixed head, fit the outlet adaptor into the top outlet hole in the valve housing

(fig.)

. The adaptor is sealed with an ‘O’ ring. Make sure the adaptor is fitted with the hose end in the valve housing. Fit the blanking plug into the bottom outlet hole using an ‘O’ ring to seal it.

If installing a riser rail, fit the outlet adaptor into the bottom outlet hole in the valve housing. The adaptor is sealed with an ‘O’ ring.

Make sure the adapter is fitted with the pipe end in the valve housing

(fig.7)

Fit the blanking plug into the top outlet hole using an ‘O’ ring to seal it

(fig.8)

. Make sure both the adaptor and blanking plug do not protrude, and finish flush with the inner face of the housing.

If fitting a tamperproof fixed head, refer to

‘Fitting the tamperproof fixed head’

section and complete the outlet pipework as follows: determine the required height of pipe and cut to size. Slide nut cover onto the pipe, followed by nut and olive. Insert the pipe into outlet adaptor, place the outlet trim onto the adaptor and fully tighten the compression nut

(fig.9)

.

Before securing the tamperproof fixed head to the wall, connect a hose to the pipework and direct to waste.

If fitting a riser rail, connect the shower hose to the outlet and direct to waste.

Open the isolating valves to the shower and flush through making sure the flow control is opened fully and the temperature control is rotated to ‘HOT’ and then to ‘cOld’ (if necessary depress the maximum temperature override button). check for any leaks and remedy if necessary.

Slide the outlet blanking trim onto the cover where it is required i.e. bottom outlet for fixed head, top outlet for a hose

(fig.0)

.

Fit the cover on and secure with two screws

(fig.)

. locate the lugs on the trim ring in the holes on the cover and twist clockwise

(fig.)

.

Finally, pull nut covers over nuts.

complete the fitting of the shower accessories by referring to the appropriate section.

using a spirit level, mark the route of incoming hot and cold water supply pipes at a distance of

153 mm centres.

Remove the plaster and brickwork to the required depth to conceal the supply pipework.

Note:

It is advisable that pipework installed in solid walls be provided with enough free play inside a cavity to allow entry into the inlet elbows for tightening, before securing the valve to the finished wall surface.

Install the hot and cold pipework — the hot pipe must enter from the left. Make sure the finished pipework projects from the front face of the tiled surface of the wall by 9.5 mm

(fig.)

.

Allow for two circular recesses measuring 32 mm diameter by 14 mm depth, to accept the rear entry pipe trims

(fig.)

.

Flush pipework to clear the system of all debris and check for leaks.

ImportaNt: The inlet elbows contain check valves that may be damaged if debris is not flushed through prior to fitting.

where this is not possible refer to the

‘flushing procedure’

on page 20.

Make good the wall and complete the tiling. check that the rear entry pipe trims are sealed in with either silicon sealant or grout

(fig.)

.

Note:

Failure to fit the rear entry pipe trims could result in the entry of water into the wall cavity.

Offer the valve, together with the inlet elbows, to the pipework making sure the inlet elbow grub screws are slack allowing the inlet elbows to be rotated to the correct position and move freely in and out of the valve housing

(fig.8)

.

check that the valve is central between the two pipes, then mark two diagonal fixing holes
