ACTUATOR ELECTRICAL WIRING
1 – (blue)
2 – (black)
3– (brown)
The actuator is factory set to motorized control and ready for operation.
Should it be inevitable to remove it or replace, please follow the instructions
in the appendix.
230 V, 50 Hz
3.2. MIXING VALVE WITH ACTUATOR
The LK 840 mixing valve is equipped with a 3-point control actuator. The current valve member
position is obvious from the position of the line in the sightglass of the control knob. The slide
switch on the actuator housing can be used to switch between motorized and manual control.
When the manual control is set, the actuator is controlled by turning the knob.
3.3. CHECK VALVE
A check valve located downstream of the filter prevents natural circulation in the heating
circuit.
3.4. FILTER WITH MAGNET
The filter located in the return line of the pump station is designed to collect particles from
heating water. It consists of a brass housing, removable stainless-steel strainer collecting
coarse dirt, and a brass lid with a magnet that attracts magnetic particles.
The filter needs to be checked regularly, and cleaned when needed. Turn off the circulation
pump, close the ball valve upstream of the filter. Water inlet downstream of the magnet is
closed by the check valve. Unscrew the filter lid, remove the stainless steel strainer and flush
thoroughly. Wipe the impurities on the magnet and re-assemble the filter by inserting the
strainer, screwing in and tightening the lid.
3.5. BALL VALVES
Ball valves are intended to isolate the pump station from the heating circuit. Then it is not
necessary to drain the heating circuit for servicing (incl. cleaning the filter). In order to have
a more solid hydraulic section of the pump station, they are fixed to the rear mounting plate.
The ball valves are controlled by a lever that is placed inside the pump station insulation. The
valve is closed or opened by turning the lever by 90°. The state of the valve is indicated by
the groove on the control hexagon of the valve. The ball valve can be accesses only after the
front section of the insulation is removed. As a result, unintentional closure of the system by
an unauthorized person is not possible.
