121 LK 550 AquaMix Technical Data LK 550 AquaMix is a mixing valve for water heating with a thermostatic element that regulates the supply of cold water in order to achieve the desired temperature. Selfcirculation is prevented with a check valve installed in the cold water supply - see under Accessories. Valves with male thread G ½” and 15 mm compression fitting have an airvent for simple draining of smaller water heaters. Arrows on the valve body indicate the direction of the flow. KV = incoming cold water VV = incoming hot water BV = outgoing warm water When fitting to a male thread connection adapter LK 373 is used - see under Accessories. When fitted on top of boiler/storage tanks with built-in water heaters the valve should be installed with some space between boiler/storage tank and valve so as not to let the function of the valve be affected by heat radiation. T he valve knob is used to set the desired warm water temperature within the range of 38°C to 65°C. The maximum temperature can be calibrated as follows: Increasing the maximum temperature: Turn the knob anticlockwise to (+). Loosen the screw and move the knob out to the side. Then turn the knob clockwise to (-) without it being engaged. Adjustments are carried out in small steps. A ¼ turn corresponds to approximately 7°C. Reinstall the knob and check that it engages with the teeth. Tighten the screw and then turn the knob to max (+). Max. calibration for increasing the temperature is a ½ turn. Reducing the maximum temperature: Do the procedure in reverse. Turn the knob clockwise to (-) and the disengaged knob anticlockwise to (+).
