This device has been installed and commissioned in accordance with the
instructions provided in the operating manual. The settings in the controller
match the local conditions.
Note!
When any factory-set values of the device are changed, you must enter
this information in the Maintenance certificate, see chapter 9.4

Note!
Confirm that installation and start-up have been carried out correctly
using the installation, start-up and maintenance certificate. This action
is a prerequisite for the making of warranty claims.
–
Have the Reflex Customer Service carry out commissioning and
the annual maintenance.
7.1
Checking the requirements for commissioning
The Servitec will be ready for initial commissioning when the tasks described in
the "Installation" chapter have been completed.
•
The Servitec has been mounted.
•
The connections of the Servitec to the system have been created and plant
system pressure maintenance is operational.
–
Degassing line to the facility system.
–
Degassing line from the facility system.
•
The water-side connection of the Servitec to the make-up has been created
and is operational, if automatic make-up is required.
•
The connection pipes of the Servitec have been purged and cleaned of
welding residue and dirt before commissioning.
•
The entire facility system is filled with water and all gases have been
vented in order to ensure a circulation through the entire system.
•
The electrical connection has been created according to applicable
national and local regulations.
7.2
Set ting the minimum operating pressure for Magcontrol
The "p
0
" minimum operating pressure is determined by the location of the
Servitec.

The calculation of the minimum operating pressure can be directly calculated
and saved during initial commissioning using the Reflex Control Smart app for
configuration. Please always check the correct inlet pressure of the expansion
vessel in the system. Proceed as follows:
1
In the app, set the controller to "Magcontrol".
2.
Determine the "P0" minimum operating pressure of the device relative to
the "p0" initial pressure of the expansion vessel.
•
The device is installed at the same level as the expansion vessel
(∆h

= 0).
–

•
The device is installed at a lower level than the expansion vessel.

Note!
The safety valve actuating pressure must always be observed for the
target value of the Servitec
(see calculation formula).
Note!
Avoid dropping below the minimum operating pressure. Vacuum,
vaporisation and the formation of vapour bubbles are thus excluded.
