4 Description Hudevad LK is a low convector radiator made of profiled steel tubes. The radiator has a flat, sleek design on both the rear and front side, making it ideal for use in front of glazing. Hudevad LK is available in two heights and with convectors for higher output. It is suitable for installation on the wall, floor, in a convector trench, under bench seating, or under the ceiling. Material Panels: Profiled steel tubes 70 x 11 x 2 mm DS/EN Convectors: 0.5 mm steel plates EN 10051, EN 10130, DIN 2395 Test pressure Max. operating pressure 13 bar 10 bar Max. operating temperature 95 C Surface treatment Length Height Depth Tappings Installation Optional extra Pretreatment: Degreasing, washing and passivation Priming: Primed with water based paint in pale grey Surface treatment in accordance with DIN and EN mm, sections in increments of 100 mm 140 and 210 mm LK 20: 84 mm LK 21: 114 mm LK 22: 144 mm LK 30: 157 mm LK 31: 187 mm LK 32: 127 mm ½ standard ETS/DS ends are 3/4 Euro cone.

Close the screw completely (right stop) and then unscrew it the number of turns required to obtain the desired radiator share. The factory-setting of the CE screw connection corresponds to a radiator share of approx. 35% (l/h) Presetting ETS/DS 1. Remove the protective cap of the thermostatic sensor 2. Lift the setting ring 3. Turn the setting ring anti-clockwise until the preferred scale value aligns with the reference point 4. Let go of the setting ring Presetting can be selected between 1 and 7 in increments of 0.5. At setting N the valve is fully open. Setting in the shaded areas of the drawing above should be avoided. When the thermostatic sensor has been installed, the presetting is locked and protected against unintended adjustment. In a one-pipe system, the setting N must be used. 10

12 Installation options Mounted on ceiling When mounting on ceiling, additional 10 o C air and room temperature is used in calculation, which means t is 10 o C lower than a corresponding floor mounting. Mounted in trench When mounting in trench, the table value for the output is reduced by approximately 20%, and to ensure the air circulation conducter plates are attached from the convector side to the under-edge of the grille. By doing that there is a division between the hot rising air and the cold descending air.
