7 Commissioning
Note!
Arrange for specialist personnel to carry out commissioning and annual maintenance.
7.1 Requirements for initial commissioning
The device will be ready for commissioning when the tasks described in the "Installation" chapter have been completed.
• The device is securely mounted.
• The connections of the device to the system have been created and plant system pressure maintenance is operational.
–
One degassing pipe to the plant system (device outlet).
– One degassing pipe from the plant system (device inlet).
• If required, the connection pipes of the device have been purged and cleaned of welding residue and dirt prior to commissioning.
• The plant system is filled with water and the majority of the gas has been vented.
–
Circulation through the entire plant system is thus ensured.
7.2 Adjusting the filling pressure of the plant system
Before the Servitec Mini is commissioned, the plant system must be filled. The volume of the Servitec Mini must be allowed for in the plant system.
Proceed as follows:
1.
Open the device ball valves.
–
Water flows in and air escapes via the degassing valve.
2. Determine the filling pressure for the plant system:
• Filling pressure “p
F
”:
p

= p

+ 0,3 bar
• Inlet pressure “p

= p

+
0,2 bar
• Static pressure “p

”:

3. Check the filling pressure of the plant system.
4. Fill the plant system with water.
–
Until the necessary filling pressure is reached.
7.3 Commissioning
Link the device to the power supply:
1.
Connect the device plug-in contact to the power supply.
2. • Press "Auto" on the controller's operator panel.
Note!
The system pressure is automatically measured by the integrated pressure sensor.
• During commissioning the Servitec Mini always measures the actual system pressure and generates a message if the pressure is
less than the target system pressure by more than 0.3 bar.
• If the system pressure is less than 0.5 bar, a low water error is triggered. Increase the system pressure accordingly.
Note!
We recommend rechecking of the pressure maintenance target value (system pressure) 2 weeks after commissioning of the Servitec Mini
and if necessary, replenishing of the system.
