Page 4: Boiler Description
Boiler description 1.0. INTRODUCTION Hot water electric boiler El-Cm Compact has a modern design and is constructed out of certified high quality materials by applying most modern robot welding technology, it is certified according to domestic and international norms and is therefore suitable for connection to central heating system installation. -
Page 5: Boiler Parts
Boiler parts OUTLET The outlet tube (1”) is marked by the blue coloured sticker and is placed on the upper left side of the electric boiler. It is inserted through the whole length of the electric boiler till its deepest point in order to spread the cooled water inside the electric boilers body and over the electric heater/heaters. - Page 6 Installation of electric boiler 4.0. INSTALLATION OF ELECTRIC BOILER The El-Cm Compact electric boiler is aimed to be hanged on the wall. For the easier setting on the wall, there is a hanging console on its back part which is to be hanged on wall metal dowels of M10 type or even stronger.
- Page 7 Connecting to the central heating system 5.0. CONNECTING THE El-Cm Compact TO THE CENTRAL HEATING SYSTEM Connecting to tube installation of the central heating system and the start-up of the electric boiler has to be executed considering all technical standards and norms, on behalf of the authorized person, who is able to take over the responsibility.
