Evinox Flushing By-pass Kit
Evinox flushing by-pass kit ensures that the ModuSat® unit can be isolated from the systems circuits.
It includes a H – shape by-pass valve for cleaning and flushing the system, there is a strainer on the
primary circuit inlet and binder points for differential pressure measurement.
Depending on the valve kit ordered the types of valves may differ. A typical valve kit is shown below.
Evinox FLUSH-KITC1 for ModuSat® XR 55R-XX, XR 55-XX and XR 70R-XX shown below.
Close isolation valves.
Leave the isolation valves in the closed position after installing the valve kit and prior to
connecting the unit as shown in the image above.
Provide isolation valves and a strainer.
If Evinox valve kit is not used, it must be ensured that there are isolation valves
provided. The strainer on the primary inlet is 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.
Setting Primary in a Flushing Position
When the unit is installed and the primary network is cleaned
or flushed, the valve kit should be used to ensure the unit is
bypassed while cleaning or flushing the system.
To open the by-pass:

Ensure both isolation valves are in the closed position as
shown in the picture. Ensure that the isolation valves
are closed slowly.

Use a suitable screwdriver or other tool to twist the
screw on the H-shape by-pass valve into the open
position.

Ensure that the primary system is clean before opening
the valves.
