Commissioning

7 Commissioning
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

Requirements for initial commissioning

The device will be ready for commissioning when the tasks described in the "Installation" chapter have been completed. Comply with
the information below on commissioning:
• The device is installed.
• The water connections to the facility system are established.
• The device shut-off valves are closed.
– Shut-off valve from the "DC" make-up line to the facility system.
– Shut-off valve from the "WC" make-up line to the fresh water system.
• "PIS" pressure monitoring is ready.
• The electrical connection has been created according to applicable national and local regulations.
Establish a 230 V power supply by plugging the power plug into a corresponding outlet. The controller is in Stop mode.
7.2 Determining the P
The "P " minimum working pressure for the device is used in systems with a diaphragm expansion tank.
0
Calculate the "P " minimum working pressure for the device:
0
– The device is installed at the same level as the diaphragm
expansion tank:
• hst = 0, P0 = p0*
– The device is installed at a lower level as the diaphragm
expansion tank:
• P = p0 + h /10*
0 st
– The device is installed at a higher level as the diaphragm
expansion tank:
• P = p0 - h /10*
0 st
* p0 in bar, h in metre
st
Note!
Calculate the filling pressure for the makeup with fresh water into the system as follows:
Filling pressure ≥ P
Note!
During planning, take into account that the working range of the device must be between the "PA" initial pressure and
the "PE" final pressure in the working range of the pressure maintenance.
