Detailed Information

Description

LK 552 HydroMix is a mixing valve for water heating and heating systems. The mixing valve has a thermostatic element that regulates the supply of cold as well as hot water in order to achieve the desired ­temperature. The valve has an anti-scald function that shuts off the ­incoming hot water flow in case of failure of cold water supply.

Arrows on the valve body indicate the direction of the flow.
C = incoming cold water
H = incoming hot water
M = outgoing mixed water

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.

The valve knob is used to set the desired warm water temperature within the specified range. The ­protective cap prevents unintentional changes of the ­temperature setting.

The valve requires no maintenance but the installation should be checked regularly.
