Please read them carefully. Please read through the whole of this book before beginning your installation. The installation MUST be carried out by a suitably competent person and in sequence of this instruction book. Care taken during the installation will give a long and trouble free life from your mixer shower. Thermostatic mixers will automatically maintain your chosen temperature, even if taps are turned on elsewhere in the house, and shut off if either the hot or cold supply fails. For the best performance within the specified running pressure range a minimum flow of eight litres per minute should be available to both inlets. The mixer shower MUST NOT be subjected to water temperatures above 80°C. This mixer is designed to operate on higher pressure systems found in the UK up to a maximum of 5 bar running pressure. The high pressure valve is suitable for modulating type combination boilers and multi-point hot water heaters. It is also suitable for thermal storage, unvented systems and pumped gravity systems. IMPORTANT: Before installing with a gas instantaneous water heater, make sure it is capable of delivering hot water at a minimum switch-on flow rate of 3 litres per minute. At flow rates between 3 and 8 litres per minute, the appliance must be capable of raising the water temperature to a minimum of 52°C. The water temperature at the inlet to the mixer must remain relatively constant when flow rate adjustments are made. Inlet connections are by compression fittings for 15 mm copper pipe. This valve unit is supplied with a mounting bracket to suit installation in a chased out cavity in a solid wall, a stud partition wall, dry lined wall or fixing to a shower cubicle or panel. SAFETY WARNINGS a. Layout and sizing of pipework MUST be such that when other services are used, pressures at the shower control inlets do not fall below the recommended minimum. b. DO NOT choose a position where the shower could become frozen. c. The outlet of this appliance MUST NOT be connected to any form of tap or fitting not recommended by the manufacturer. d. The showerhead MUST be regularly cleaned to remove scale and debris. e. Conveniently situated isolating valves in each inlet supply MUST be fitted as an independent method of isolating the shower should maintenance or servicing be necessary. f. If it is intended to operate the shower in areas of hard water (above 200 ppm temporary hardness), a scale inhibitor may have to be fitted. For advice on the Triton scale inhibitor, please contact Customer Service. g. Do not operate the shower outside the guidelines as laid out in 'site requirements'. Replacement parts can be ordered from Customer Service. See 'spare parts' for details and part numbers. Combi HP thermostatic mixer shower MAIN COMPONENTS (fig.1) 1. Inlet nuts and olives 2.

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. While the mixer valve is operational (open outlet), inlet pressures MUST NOT be capable of exceeding 7 bar. For effective operation of the internal seals, the maximum static pressure must not be exceeded. Note: On sites where the running pressure is above 5 bar, the use of a suitably sized pressure reducing valve fitted in the cold mains supply pipework can provide nominally equal pressures at the mixer valve. This should be installed as indicated on the appropriate diagrams shown on the following pages,andsettowithin the specification of the valve. For the best performance of this shower both hot and cold water supplies to the shower valve should be fed at nominally equal pressures. The pipework should be installed such that the flow is not significantly affected by other taps and appliances being ...
