Page 7: Installation Requirements
Section Installation Requirements 1. General Read the section "Important Safety Information" first. 1.1. Supply pipework MUST be flushed to clear debris before connecting the shower control. 1.2. Do not fit any form of flow control in the outlet pipework. 1.3. Do not install the product in a position where it could become frozen. 1.4. - Page 8 2.1. Instantaneous gas-heated showers (e.g. combination boilers) - The shower 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 rate to the burner). A drop tight pressure reducing valve (PRV) MUST be fitted if the supply pressures exceed 3 bar maintained.
- Page 9 2.2. Gravity fed showers - The shower control MUST be fed from a cold water storage cistern and hot water cylinder providing nominally equal pressure.
- Page 10 2.3. Mains pressurised instantaneous hot water shower, heated from a thermal store - Packages of this type, fitted with a tempering valve can be used with the Mira Realm. A drop tight pressure reducing valve MUST be fitted if the supply pressures exceed 3 bar maintained.
- Page 11 2.4. Unvented mains pressure showers - The shower can be installed with an unvented, stored hot water cylinder. Only a "competent person" as defined by the Building Regulations may fit this type of system. For packages with no cold water take off after the appliance reducing valve, it will be necessary to fit an additional drop tight pressure reducing valve when the mains pressure is over 3 bar.
- Page 12 2.5. Pumped showers (inlet pumps) - The shower can be installed with an inlet pump (twin impeller). The pump MUST be located on the floor next the hot water cylinder. The hot water cylinder/vent pipes must be arranged as shown to achieve air separation.
