Installation
− connect ’servitec’ with the system piping. The maximum permissible media temperature at the connection
point is 70 °C (’servitec .../90 °C’ are applicable up to 90 °C), which is why it is installed in the system return
in the case of heating systems.
− connect in the immediate vicinity of the expansion line so that protection by way of the system safety valve
is provided. Otherwise, additional protection will be required.
− maintain a minimum distance between the connection points of 500 mm,
− note flow direction,
− rinse pipelines.
Installation diagrams
− Caution dirt! Connect connection lines from the top
or as immersion pipe as shown. Never integrate edgeless
from below (danger of contamination).
− With ’servitec .../gl’ a dirt trap (mesh size 0.25 mm) must
be provided in the overflow line O by the customer in
order to protect the additional solenoid valve (7) from
contamination.
− ’servitec’ deaeration operation is ensured only if ’servitec’
is connected to a representative main flow of the system.
The following minimum flow rates V must be maintained
during operation.
− Use the following pipe dimensions:
