Combi HP thermostatic mixer shower Siting requirements SITE REQUIREMENTS The installation must be in accordance with Water Regulations/Bylaws. Minimum running water pressure: 1 bar. Maximum running water pressure: 5 bar. Maximum static water pressure: 10 bar. For the best performance within the specified pressure range both hot and cold water supplies must be fed from a common supply and a minimum flow of 8 litres per minute should be available to both inlets.
Combi HP thermostatic mixer shower TYPICAL SUITABLE INSTALLATIONS Typical suitable installations Fig.2 diagrammatic view (not to scale) a) Instantaneous gas-heated showers, e.g. combination boilers (fig.2) The shower control must be installed with a multipoint gas water heater or combination boiler of a fully modulating design (i.e. where the water draw-off rate indirectly controls the gas flow to the burner).
Combi HP thermostatic mixer shower packages with a cold take off after the pressure reducing valve to the cylinder. Fig.4 diagrammatic view (not to scale) The layout and sizing of pipework must be such that nominally equal inlet supply pressures are achieved and the effects of other draw-offs are minimised. Mixer shower d) Mains pressurised thermal store Safety devices not shown (fig.5) Packages of this type, fitted with a tempering valve (blender valve) can be used.
Combi HP thermostatic mixer shower PREPARING MIXER Preparing theTHE mixer valve VALVE Before starting the installation, make sure all the openings on the valve are carefully covered to prevent ingress of any debris etc. Fig.6 diagrammatic view (not to scale) Note: It is not necessary to remove the control knobs at any stage. SITING THE SHOWER Siting ofOF the shower WARNING! The shower must not be positioned W-008-A where it will be subjected to freezing conditions.
Combi HP thermostatic mixer shower FITTING THE SHOWER TO THE WALL Fitting the shower to the wall - Exposed Fig.8 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.
Combi HP thermostatic mixer shower Fig.13 screws are slack allowing the inlet elbows to rotate to the correct position and move freely in and out of the valve housing (fig.8). Fig.14 Place the valve housing centrally between the two pipes, and mark the two diagonal fixing holes (figs.9 and 10). Remove the valve. Drill and plug the holes.
Combi HP thermostatic mixer shower 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. Fig.18 Make sure the adapter is fitted with the pipe end in the valve housing (fig.17) Fit the blanking plug into the top outlet hole using an ‘O’ ring to seal it (fig.18). Make sure both the adaptor and blanking plug do not protrude, and finish flush with the inner face of the housing.
Combi HP thermostatic mixer shower Rear entry supplies Fig.22 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 (fig.23). 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.
Combi HP thermostatic mixer shower Remove the valve. Drill and plug the holes using the wall plugs supplied. Fig.25 = Using two hexagonal nuts (supplied), 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. = Tighten the inlet nuts with the spanner supplied (fig.27) then tighten the inlet elbow grub screws. Screw to the wall with the screws supplied.
Combi HP thermostatic mixer shower Fig.28 where it is required i.e. bottom outlet for fixed head, top outlet for a hose (fig.20). Fit the inlet blanking trims on the underside of the cover (fig.28). Fit the outlet trim over the outlet adaptor and slide the cover on (fig.19). Secure the cover with two screws (fig.21). Locate the lugs on the trim ring in the holes on the cover and twist clockwise (fig.22). Complete the fitting of your shower accessories.
Combi HP thermostatic mixer shower FITTING THE SHOWER TO THE WALL Fitting the shower to the wall - Built-in Fig.29 Flush fit Note: The outlet of the shower must not be connected to anything other than the hose, showerhead or fixed showerhead supplied. 77 Do not use jointing compounds on any pipe fittings for the installation. .5 200 mm Do not solder fittings near of the shower unit, as heat transfer can damage components.
Combi HP thermostatic mixer shower shower from the top (falling), the bottom (rising) or the rear. Fig.31 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.29).
Combi HP thermostatic mixer shower Where this is not possible refer to the ‘flushing procedure’ on page 20. Fig.34 Refit the valve to the mounting bracket/wall surface and pipework (fig.32). 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.
Combi HP thermostatic mixer shower Fit the flush mount cover (fig.37). Locate the lugs on the trim ring in the holes on the cover (fig.38) and twist clockwise. Fig.37 Complete the fitting of your shower accessories. Hollow wall The wall mounting bracket supplied with the shower is suitable for use on a plasterboard wall of 9.5 mm or 12.5 mm in thickness. Decide on the shower position and whether the hot and cold water supplies will enter the shower from the top (falling), the bottom (rising) or the rear.
Combi HP thermostatic mixer shower washer. Fig.40 Make sure the inlet elbows are positioned the correct way. Offer the valve up to the mounting bracket and secure using the screws provided (fig.42). 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.
Combi HP thermostatic mixer shower drill and plug the holes. Fig.43 Seal tight up to shroud Note: If fitting to plasterboard, use suitable cavity fixings. Break off the alignment tabs on the flush mount plate (fig.36). 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. Fit the flush mount cover (fig.37).
Combi HP thermostatic mixer shower correct way. Offer the valve up to the mounting bracket and secure using the screws provided. Fig.46 Secure the mounting bracket together with the valve to the panel using two bolts in the innermost fixing holes (fig.46). Complete the pipework to the shower marking off the length to enter the elbows. Remove the valve and mounting bracket and cut the pipes to length. If fitting a fixed head, make a hole in the panel for the fixed head position.
Combi HP thermostatic mixer shower Fig.50 FLUSHING PROCEDURE Flushing procedure Removal and/or fitting of check valves for maintenance Important: It is preferable to flush the pipework before installing the valve. Where this is not possible, the procedure using a flushing cartridge should be followed. a. Isolate the supplies. b. Remove the trim ring by twisting anticlockwise. c. Remove the valve cover.

Combi HP thermostatic mixer shower FITTING THE FIXED Fitting the fixed headHEAD - Built-in Fig.65 (Built in option only) The outlet pipe should protrude from the surface of the wall between 50 mm and 65 mm (fig.65). 50 mm – 65 mm Mark four fixing hole positions by using the fixed arm as a template. Drill and plug the wall using the plugs supplied. Care must be taken not to drill into the buried pipework. Outlet pipe Remove burrs on the pipework to prevent damage to the ‘O’ ring.
Combi HP thermostatic mixer shower FITTING THE BULKHEAD Fitting the bulkhead Fig.68 (Riser rail option only) Complete the outlet pipework ending in a ½" x 15 mm female thread fitting (fig.68).
