LK 548 is AquaKit a valve combination for water heating consisting of a shut-off/check valve and a thermostatic mixing valve. 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.

Arrows on the valve body indicate the direction of the flow.
KV = incoming cold water
VV = incoming hot water
BV = outgoing warm water

Female 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.

When 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.
The valve knob is used to set the desired warm water tempe-rature 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 (+).
