3. Transport of the boiler NOTE: Transport damages Pay attention to transport instructions found on the packaging Use a suitable transport vehicle, e.g. a trolley with a tightening strap. During the transport, the boiler must be in a lying position. Avoid blows or collision with various objects.
Prior to any works on the heating installations, the power supply should be disconnected. Unskilled and unauthorised attempts of connecting under voltage may cause material damage on the boiler, which may further lead to dangerous electric shocks. 4.2 Clearance around the boiler to floor, wall and ceiling DANGER: Risk of fire due to flammable materials or liquids! Do not store flammable materials or liquids in the vicinity of the boiler.
4.3 Removal of the boiler front casing Prior to any intervention (removal of the casing), disconnect the boiler from the installation. Boiler casing may be removed for easy handling and installation. Boiler removal is performed in the following way: 1. Unscrew the screws at the left, as shown in the picture. 2.
Picture 5. Position of screw anchors for assembly a=220mm; b=80mm; c=23mm; d=560mm 5. Boiler hydraulic scheme Heat pipes should be connected in the following manner Connect the cold water connection to the connection 8, picture 3. Connect the hot water connection to the connection 9, picture 3. Filling the boiler with heating water and testing welded joints and tightness: Testing tightness should be carried out before commissioning the boiler.

Take off the hose from the filling and drainage tap. Note down the value of the working pressure and water quality in the instruction for use. During the first filling or refilling or changing the water Comply with the request related to filling water. Purging and unblocking the heating pump Pump installed in this boiler has an automatic manner of purging, therefore, there is no need to undertake any actions to purge the pump.
Cables must have the prescribed cross-section, and the fuses must have the prescribed power. Models EK 06 Smart EU, EK 09 Smart EU, EK 12 Smart EU, EK 16 Smart EU, EK 18 Smart EU, EK 21 Smart EU, EK 24 Smart EU, EK 27 Smart EU (400V 3N ~).
