Combi HP thermostatic mixer shower

Flush fit

Note:

The outlet of the shower must not be connected to anything other than the hose, showerhead or fixed 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 the specification of the valve.

The hot water pipe entry must be on the lefthand side.

This mixer valve also includes a wall bracket which allows the installer to mount the shower into a solid, stud partition or other hollow wall structures. The bracket can also be used for fitting in a shower cubicle providing the back of the cubicle is accessible.

when installing into a stud partition or other hollow wall structure the installer may wish to consider building rear supports or other options.

Such options are beyond the scope of this guide.

Solid wall

The building-in depth for the shower into a solid wall is between 57 mm and 66 mm. The building-in depth calculation must include the thickness of the plaster and tiles. This dimension determines how much of the shower control is visible through the concealing plate when the installation is completed.

Seal tight up to shroud shower from the top (falling), the bottom (rising) or the rear.

Mark the route of the incoming and outgoing pipework.

Note:

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

Remove the plaster and brickwork to the depth shown

(fig.9)

. where applicable, chase out any additional areas of the wall for the pipework to either the bulkhead or fixed head.

Offer the mounting bracket up to the wall and mark the two plain fixing holes

(fig.0)

. drill and plug then screw bracket to the wall.

Note:

The valve can be fitted to the mounting bracket if required or secured directly to the wall with the screws supplied.

If installing a fixed head, the outlet adaptor needs to be fitted 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

(fig.7)

in the valve housing.

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

If fitting a bulkhead outlet, the outlet adaptor needs to be fitted into the bottom outlet hole in the valve housing. The adaptor is sealed with an

‘O’ ring. Make sure the adaptor is fitted with the hose end in the valve housing

(fig.7)

.

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

Make sure the inlet elbows are positioned correctly. Offer the valve up to the mounting bracket or wall surface, and secure using the screws provided

(fig.)

.

complete the pipework to the shower marking off the length to enter the elbows. Remove the valve and cut the pipes to length.

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.

Refit the valve to the mounting bracket/wall surface and pipework

(fig.)

. Tighten the inlet nuts and inlet elbow grub screws.

If fitting a fixed head, refer to the

‘Fitting the fixed head’

section and complete the outlet pipework to the fixed head position.

Note:

The outlet pipe for the fixed head should protrude from the surface of the wall between

50 mm and 65 mm. Before fitting the fixed head to the wall, connect a hose to the pipework and direct to waste.

If fitting a riser rail kit, refer to

‘Fitting the bulkhead’

and complete outlet pipework.

Before fitting the bulkhead to the wall connect the shower hose and direct it to waste.

Open the isolating valves to the shower and flush through checking that 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 leaks and remedy if necessary.

If a fixed head is installed, make good the outlet pipe channel.

Note:

If fitting a fixed head, the tiling around the outlet pipe must be as tight as possible so that the special lock washer will seat, otherwise a larger diameter washer will have to be placed behind the lock washer.

Make good the wall surface around the valve and make sure the plastering/sealing is taken tight to the PVc shroud

(fig.)

.

Should the shroud protrude beyond the wall surface, trim flush with a sharp knife

(fig.)

.

Offer the flush mount plate up to the finished tile surface and making sure the valve and plate are aligned, mark the ‘arrowed’ fixing holes

(fig.)

. Remove the flush mount plate then drill and plug holes.

Break off the alignment tabs on the flush mount plate

(fig.)

. Place a ring of silicon sealant round the plate so that the plate seals against the wall. Secure the plate to the wall using the screws provided. wipe off any excess sealant.
