Checking switching points

Prerequisite for checking the switching points are the following correct settings:
• Minimum operating pressure P
points" on page 10 .
• 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, see chapter 10.4 "Cleaning the
vessel" on page 16 .
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, see chapter 9.2.1 "Default
settings" on page 13 .

Cleaning

10.3.1 Cleaning the vessel
CAUTION
Risk of injury due to pressurised liquid
Injuries can occur during maintenance work if the connections have been
installed incorrectly because condensate under pressure can suddenly
escape.
• Ensure proper connections for the draining of condensate.
• Wear suitable personal protective equipment (safety gloves and safety
goggles, for example).
Regularly clean the vessel to remove condensate. The cleaning intervals depend
on the local operational conditions.
Vessel with permanently installed diaphragm
1 Record the level value displayed at the controller.
2. Press "Manual" at the operator 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.
CAUTION – Risk of injury caused by escaping pressurised liquid.
Injuries can occur during maintenance work if the connections have been
installed incorrectly because condensate under pressure can suddenly
escape. Ensure proper connections for condensate draining. Wear suitable
personal protective equipment (safety glasses and safety gloves, for
example).
5. Slowly open the "PV" overflow solenoid valve.
– Manually add water if the pressure in the system circuit drops
significantly.
– If the "PV" overflow solenoid valve discharges more than 5 litres of
water or condensate, you must check the diaphragm for rupture.
• The vessel must be replaced if the diaphragm 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 you had to add water during draining 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.
