3.3 Pipework, Fittings and Outlet / Terminal Fittings systems and have a rated operating pressure of at least 6 bar. Where plastic pressure must be achievable at outlet temperatures that can be expected within the hot water distribution pipework. If in doubt, consult the manufacturer of the The Electromax unvented cylinder can be used in conjunction with most types of mixer showers or taps to have balanced pressure hot and cold water supplies, in these instances the balanced cold water supply should be teed off the supply to the Electromax immediately after the Cold Water Combination Valve (see diagram 5). Branches to cold outlets where drinking water may be drawn should be taken directly from the main supply before the Cold Water Combination Valve to avoid the possibility of warm expanded water being drawn from cold taps. 3.4 Treatment of the Primary (Central Heating) Circulating System Primary water circulating systems will be subject to corrosion unless an appropriate water treatment is applied. Without treatment over time as corrosion sludge accumulates within the system, risking damage to the pump and valves, system noise and circulation problems.

For optimum performance after installation the Electromax boiler and its associated accordance with the guidelines given in BS 7593:1992 “Treatment of water in domestic hot water central heating systems”. This must involve the use of a proprietary cleanser, such as GE Betz Sentinel X300 or X400, Fernox Follow the manufacturer’s instructions to ensure correct cleansing of the system. For long term protection against corrosion be dosed with an inhibitor such as GE Betz Sentinel X100, Fernox MB-1 or Copal, or Salamander System Inhibitor in accordance with the guidelines given in BS 7593:1992. system will invalidate the appliance warranty. 3.5 Sealed Primary Systems The Electromax boiler must be installed in a sealed primary system. All necessary primary Electromax. The sealed system expansion vessel fitted has a capacity of 12 litres which, as a general guide, will be suitable for a heating system of up to 107 litres. If in doubt the total primary system volume must be calculated to determine if additional expansion volume is required. The Electromax initial primary system cold size = 0.11 x the total system volume. The boiler and pipework within the Electromax hold approx. 2 litres of water, therefore additional system expansion volume will only be necessary for systems that exceed 107 litres. The Electromax boiler incorporates an to the pump housing, see Diagram 6). If any primary pipework is routed above the level of the Electromax additional air vents must return pipes and at any point where air is likely to collect.
