3.2. CHECK VALVE
The check valve downstream of the filter prevents natural circulation in the heating circuit.
3.3. FILTER WITH MAGNET
The filter located on the return line of the pump station is designed to collect solid particles
from the working fluid. It consists of a brass housing, a removable metal strainer collecting
coarse impurities and a brass cap with magnet that collects magnetic impurities.
The filter should be checked regularly and cleaned if necessary. The filter shall be cleaned
with the circulation pump switched off and the section where the filter is installed shut
off. In the section upstream of the filter, shutting off is done by a ball valve, in the section
downstream of the filter the piping is shut off by a check valve. The filter cap needs to be
unscrewed, the metal strainer removed and rinsed thoroughly from any dirt. Dirt trapped on
the magnet must be wiped off and then reassembled by inserting the strainer, screwing in
and tightening the cap.
3.4. 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 not present on the valve during operation.
The valve is closed by turning the lever clockwise by 90°. The open / closed position on the
ball valve is indicated by a groove on the control wheel. The groove is perpendicular to the
direction of flow when the ball valve is closed. The ball valve opens by turning the lever anti-
clockwise by 90°, the groove is then in the flow direction. Before closing / opening the ball
valve, the top section of the insulation shall be removed first. As a result, unintentional closure
of the system by an unauthorized person is not possible.
