The serial number consist of thirteen digits. The third and the fourth digit of the serial number is the year of production, the fifth and the sixth is the month of production, the tenth and the eighth is the day of EWH production.Description and operating principleEWH consists of the housing, tubular electric heater, heat exchanger (for ER models: 05022 480, 08022 480, 10022 480, 15022 480, 05022 481, 08022 481, 10022 481, 15022 481), safety valve and protective cover.Housing of the EWH consists of the steel tank, thermally insulated by the environmentally-friendly polyurethane foam, two threaded cold water inlet pipes (with blue ring) and hot water outlet pipe (with red ring). ER models: 05022 480, 08022 480, 10022 480, 15022 480, 05022 481, 08022 481, 10022 481, 15022 481 are equipped with boiler water inlet pipe (with red ring) and boiler water outlet pipe (with blue ring).Inner tank is equipped with special glass-porcelain coating, securely protecting internal surface from chemical corrosion.ENfor EWH with volume 30 liters1,5 kWRemovable flange has tubular electric heater (THE) (7), thermostat (8) and magnesium anode (9). TEH is designed for water heating, and thermostat ensures the possibility of heating temperature adjustment up to +74°С (±5°C). Magnesium anode is designed to neutralize the electrochemical corrosion affect on the inner tank.Adjustment of the water temperature in the inner tank is carried out by means of the thermostat control unit (10), located on the protective cover of the water heater. Thermostat is also equipped with the thermal switch - EWH overheating protection device, switching off the TEH from the network in case of water temperature rise over +93°С (±5°С). During the operation the housing of EWH may be heated. Activation of the thermal protection system is not a failure. Reset of the water heater to the operating condition shall be carried out by pressing the rod of the thermal switch, located under the protective cover of EWH (Fig. 4).Safety valve operates as the check valve, ensuring protection of the water ingress from the water heater into the sewage system in case of pressure drop in the sewage system and in case of pressure rise in the tank at high water heating, as well as the functions of the safety valve, releasing overpressure in the tank at high water heating.Protective cover of the device is equipped with the control indicator lamp (11) – reflects EWH operation in the autonomous mode, lights up during water heating and fades while reaching the preset temperature.Installation and connectionAll installation, plumbing and electrical fitting works shall be carried out by the qualified personnel.Arrangement and installationEWH installation shall be carried out in accordance with the marking on the casing and the following table:
horizontalvertical
It is recommended to install EWH in the vicinity of the hot water use area, to reduce heat losses in the pipes. Depending on the model selected, 2 or 4 anchors are required. During the installation area selection it is necessary to consider the gross weight of EWH filled with water. The wall and the floor with low load-carrying capacity shall be reinforced. While drilling (making) the holes in the walls, mind embedded cables, channels and pipes. EWH shall be sus-pended on the wall anchor hooks using the housing brackets.Installation of the hooks in the walls shall exclude self-movement of the EWH brackets. For EWH maintenance the distance from the protective cover to the nearest surface in the direction of the removable flange axis shall be at least 0,5 m.ENBasic technical specifications
