Maintenance
10.2
Checking switching points
Prerequisite for checking the switching points are the following correct settings:
•
Minimum operating pressure P
•
Level sensor at the primary vessel.
Preparation
1.
Switch to Automatic mode.
2.
Close the cap valves upstream of the vessel.
3.
Record the displayed filling level (value in %).
4.
Drain the water from the vessel.
Check cut-in pressure
5.
Check the cut-in and cut-out pressure of the "CO" compressor.
–
The compressor cuts in at P
–
The compressor cuts out at P
Check make-up "On"
6.
If necessary, check the make-up value displayed at the controller.
–
The automatic make-up is activated at a level display of 8 %.
Checking Insufficient water "On"
7.
Switch off the water make-up and continue to drain the water from the
vessel.
8.
Check the displayed value for the "Insufficient water" filling level message.
–
Insufficient water "On" is displayed at the controller at a minimum filling
level of 5 %.
9.
Switch to Stop mode.
10. Switch off the main switch.
Cleaning the vessel
If necessary, remove condensate from the vessel, 10.3 "Cleaning the vessel",
36.
Activating the device
11. Switch on the main switch.
12. Switch to Automatic mode.
–
Depending on the filling level and pressure, the "CO" compressor and
the automatic make-up will be switched on.
13. Slowly open the cap valves upstream of the vessel and secure them against
unintended closing.
Checking Insufficient water "Off"
14. Check the displayed value for the Insufficient water "OFF" filling level
message.
–
Insufficient water "Off" is displayed at the controller at a minimum filling
level of 8 %.
Check make-up "Off"
15. If necessary, check the make-up value displayed at the controller.
–
The automatic make-up is deactivated at a level display of 12 %.
Maintenance is completed.
Note!
If no automatic make-up is connected, manually fill the vessel with water
up to the noted level.
Note!
The setting values for pressurisation, filling levels and make-up can be
found in the chapter Default settings, 9.2.1 "Default settings", 32.
10.3
Cleaning the vessel
CAUTION
Risk of injury due to pressurised liquid
Injuries can occur during maintenance work if the installation of the
connections is incorrect because pressurised condensate can suddenly
escape.
•
Ensure proper connections for the draining of condensate.
•
Wear suitable personal protective equipment (safety gloves and safety
goggles, for example).
•
Ensure that the system is depressurised.
Regularly clean the vessel to remove condensate. The cleaning intervals depend
on the local operational conditions.

Vessel with replaceable membrane
1
Record the level display value shown on the controller.
2.
Press "Manual" at the control panel to switch the controller into Manual
mode.
3.
Remove the silencer from the "PV" overflow solenoid valve.
4.
Install a suitable hose in the "PV" overflow solenoid valve to drain
condensate.
5.
Slowly open the "PV" overflow solenoid valve.
–
If the pressure in the system circuit drops significantly, the water must
be made up manually.
–
If the "PV" overflow solenoid valve discharges more than 5 litres of
water or condensate, you must check the membrane for rupture.
•
The vessel must be replaced if the membrane has ruptured.
6.
Close the "PV" overflow solenoid valve if the display indicates a 100 % level.
7.
Start the "CO" compressor to build up pressure.
–
If water had to be manually made up during draining of the
condensate, you must monitor the pressure build up. At excessive
pressure rise, drain water from the system circuit accordingly.
8.
Switch the controller into Automatic mode when the recorded level is
displayed at the controller.
9.
Remove the hose from the "PV" overflow solenoid valve and fit the silencer.
10. Maintenance is completed.
Regularly clean the primary vessel to remove condensate. The cleaning intervals
depend on the local operational conditions.
10.3.1 Cleaning the dirt trap
Regularly clean the "ST" dirt trap. The cleaning intervals depend on the local
operational conditions.
1
"ST" dirt trap
1.
Switch to Stop mode.
–
Press "Stop" on the controller's operator panel.
2.
Close the ball valves upstream and downstream of the "ST" (1) dirt trap.
3.
Slowly unscrew the dirt trap insert (2) from the dirt trap in order for the
residual pressure to escape from the pipeline segment.
4.
Pull the mesh from the dirt trap insert and rinse it with clear water. Use a soft
brush for cleaning.
5.
Re-insert the mesh into the dirt trap insert, check the gasket for damage, and
screw the dirt trap insert back into the housing of the "ST" (1) dirt trap.
6.
Re-open the ball valves upstream and downstream of the "ST" (1) dirt trap.
7.
Switch to Automatic mode.
–
Press "Auto" on the controller's operator panel.
Note!
Clean all other installed dirt traps (in the Reflex Fillset, for example).
10.4
Inspection
10.4.1 Pressure-bearing components
Comply with all applicable national regulations for the operation of pressure
equipment. Before testing pressurised parts, they must first be depressurised (see
disassembly).
For vessels compliant with EN 13831, the following applies:
Material fatigue does not arise from the intended use in heating and cold water
systems (see also EN 13831 para. 6.1.8).
10.4.2 Inspection prior to commissioning
In Germany, follow the Industrial Safety Regulation
[Betriebssicherheitsverordnung] Section 15 and Section 15 (3) in particular.
