Maintenance
CAUTION
Risk of burns
Escaping hot medium can cause burns.
•
Maintain a sufficient distance from the escaping medium.
•
Wear suitable personal protective equipment (safety gloves and
goggles).
DANGER
Risk of serious injury or death due to electric shock.
If live parts are touched, there is risk of life-threatening injuries.
•
Ensure that the system is voltage-free before installing the device.
•
Ensure that the system is secured and cannot be reactivated by other
persons.
•
Ensure that installation work for the electric connection of the device is
carried out by an electrician, and in compliance with electrical
engineering regulations.
The device is to be maintained annually.
–
The maintenance intervals depend on the operating conditions and the
degassing times.
The annual maintenance is displayed upon expiry of the set operating time. Use
"Quit" to acknowledge the "Maintenance recommended" message. Reset the

Checking switching points
Prerequisite for checking the switching points are the following correct settings:
•
Minimum operating pressure P
27.
•
Level sensor at the primary vessel.
Preparation
1.
Switch to Automatic mode.
2.
Close the cap valves upstream of the vessels.
3.
Record the displayed filling level (value in %).
4.
Drain the water from the vessels.
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"

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 vessels
If necessary, remove condensate from the vessels, 10.3.1 "Cleaning the tanks",
32.
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 vessels 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 vessels 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", 30.
10.3
Cleaning
10.3.1
Cleaning the tanks
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 vessels to remove condensate. The cleaning intervals depend
on the local operational conditions.
Vessels with replaceable diaphragm
1.
Close the cap valve in front of the vessels.
2.
Record the displayed level value at the controller and empty the vessel of
water and compressed air.
3.
Switch off the main switch and withdraw the mains plug.
4.
Open the drain taps at the vessels and drain the condensate.
–
If more than 5 litres of water or condensate are discharged, you must
check the vessel.
•
Check the diaphragm for rupture.
•
Check the vessel interior walls for corrosion damage.
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.
5.
Close the vessels' drain taps.
6.
Connect the mains plug and switch on the main switch.
7.
Open the cap valve of the vessels and secure against unauthorised
"closing".
8.
Fill water and compressed air into the vessels until the recorded level value
is reached.
Maintenance is completed.
Note!
Check the installation location of the vessels for sufficient ventilation if
the vessel interior wall are damaged by corrosion, 6.2 "Preparatory
work",
23.
