The shut-off valve closes the cold water inlet and has an integrated check valve preventing ­recirculation of warm water into the incoming cold water pipe. The mixing valve regulates the supply of cold water in order to achieve the desired temperature. The shut-off\/check valve has two connections with female thread M ½” for fitting of a safety relief valve, vacuum breaker or filling valve.\u003cbr\u003e\u003cbr\u003eArrows on the valve body indicate the direction of the flow.\u003cbr\u003eKV = incoming cold water\u003cbr\u003eVV = incoming hot water\u003cbr\u003eBV = outgoing warm water\u003cbr\u003e\u003cbr\u003eFemale thread connections are designed for the LK Armatur O-ring seal system. Other components are fitted in the usual way. When fitting to a male thread connection, adapter LK 373 is used - see under Accessories.\u003c\/p\u003e\n\u003cp\u003eWhen fitted on top of boiler\/storage tanks with built-in water heaters the valve combination should be ­installed with some space between boiler\/storage tank and ­valve combination so as not to let the function of the valve ­combination be affected by heat radiation.\u003c\/p\u003e\n\u003cp\u003eThe 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:\u003cbr\u003e\u003cbr\u003eIncreasing the maximum temperature:\u003cbr\u003eTurn 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.\u003cbr\u003e\u003cbr\u003eReducing the maximum temperature:\u003cbr\u003eDo the procedure in reverse. Turn the knob clockwise to (-) and the disengaged knob anticlockwise to (+).\u003c\/p\u003e","brand":"LK","offers":[{"title":"Default Title","offer_id":55178495263096,"sku":"090085","price":107.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0799\/5523\/1002\/files\/LK548__AquaKit.jpg?v=1750934713","url":"https:\/\/heatpumpparts.eu\/products\/lk-548-aquakit-compression-fitting","provider":"Heat Pump Parts","version":"1.0","type":"link"}
