Close valves
Before connecting flushing by-pass kit to the HIU ensure all isolation valves are
closed. Valves can be opened after LTHW system has been flushed.
Heating strainer
In HIUs with the bottom connections, strainer cannot be installed in vertical
position with the water flow going up.
Flushing Primary Circuit
The whole primary system should be cleaned and flushed in
accordance to BG29/2012 before filling ModuSat® heat
interface unit.
To open the by-pass:
Ensure both isolation valves are in the closed position as
shown in the picture.
Use a suitable screwdriver or other tool to twist the
screw on the H-shape by-pass valve into the open
position.
Close the bypass after flushing is complete.
Provide isolation valves and a strainer.
If Evinox valve kit is not used, it must be ensured that there are isolation valves
provided. Strainers on the primary and secondary heating inlets are required to ensure
the components in the unit are protected from debris and sediments.
Tighten the connections.
When connecting the ModuSat® heat interface unit, ensure that all the connections are
tightened to avoid any leaks.
