Page 12: Installation
3 Installation 3.1 Handling Care should be taken when handling the Inox-Maxi cylinders to avoid damage to the outer insulation. Models 800 and larger, are supplied with lifting points on the top of the cylinder. 3.2 Position The position chosen for installation must be capable of supporting the unit when full of water and it is important to ensure that the unit is true and vertical to avoid the possibility of difficulties with air trapping and or locking in primary coils. -
Page 13: Hard Water
8 Hard Water In known hard water areas the use of scale prevention measures is recommended. Ensure compatibility with stainless steel material. No warranty is provided for components such as immersion heaters that are damaged through scale build up. In particular water quality must be considered so as to ensure reliable operation of the system - refer to ICOM Publication - Water quality consideration for non domestic hot water systems 9 Unvented Systems... -
Page 14: Safety Relief Valves Discharge Pipes
12 Safety Relief Valve Discharge Pipes It is a requirement of the Building Regulations that any discharge from an unvented system is conveyed safely to a point that is visible but will not constitute a hazard or danger to persons in or about the building. It is the responsibility of the installer to supply and install discharge pipes and suitable tundishes, in accordance with the requirements of the Building Regulations. - Page 15 Operation - Ensure that the element is immersed in the water as this includes a thermostat to sense the water temperature. In the event of a shutdown due to overheating, the main isolator must be switched off before checking the system, the water level should be checked and the system inspected.

Page 19: Commissioning
17 Commissioning If the installation is unvented, before filling the system with water, check the air pressure in the potable water expansion vessel and adjust as necessary to a nominal 3.5bar. If the pressure regulating valve supplied with the unvented kit is an adjustable type, ensure that the setting is limited at a maximum of 3.5bar. -
Page 20: User Instructions
19 Regular Maintenance To ensure safe and continued performance of the water heater it is a requirement that the unit should be regularly maintained and only genuine spare parts from Elco Heating should be used. Maintenance should be carried out at intervals not exceeding 12 months by a competent installer In hard water areas, immersion heaters should be periodically de- scaled. -
