The LK ARMATUR LK 550 AquaMix is a mixing valve for domestic hot water systems.

Applications and regulation

  • Domestic hot water systems: regulation of the mixed water temperature according to the system design.
  • Connection via kit: consider the final 3/4'' male size for matching with the system fittings.
  • Installation near boilers and storage tanks: comply with the requirements regarding spacing and protection from heat.
  • Maximum temperature setting: the manufacturer describes a procedure for repositioning the knob. The adjustments occur in steps; a quarter turn corresponds approximately to 7 °C and the maximum described increase is half a turn. Follow the manual completely, without exceeding the product limits, and verify the actual temperature.
Installation and warnings: distinguish the G 1'' male threads of the body from the 3/4'' male final connections of the assembled kit. Respect the flow arrow, the KV/VV/BV abbreviations, and the direction of the non-return valves. In case of mounting on a boiler or storage tank, the manufacturer requires a spacer pipe and protection from radiant heat. Entrust the mounting and setting to qualified personnel. Water at 65 °C can cause burns: check the temperature at the outlets. In the provided data, a hot water shut-off function in case of cold water failure is not specified; do not present the product as a certified anti-scald device. Verify pressures, inlet temperatures, and allowed flow rates in the documentation. Kvs is not a guaranteed flow rate in any circuit.
