LK 545-22 AquaMix
LK 545-22 AquaMix LK 545 is a mixing valve for tapwater designed for connection to hot water heaters, together with manifold LK 508. Arrows on the valve body indicate the direction of flow. • KV = incoming cold water • VV = incoming very hot water • BV = outgoing hot water The mixing valve has a compression fitting for installation with copper or steel pipes. When installing to an external thread, adapter LK 373 is used – see under Accessories. KV connection tube adapter ø22 mm. Installation of the compression fitting is facilitated if lubricant is applied to the thread and chamfer. Tighten manually as far as possible, then use a fixed wrench. Tightening, number of turns with wrench plus other technical data, please see separate data sheet for Compression fittings. Soft pipes are fitted with support sleeves. The valve requires no maintenance. The installation should be checked regularly. The 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 (+).
