Filling the device with water and venting

1 Vacuum gauge "PI"
2 Degassing valve "DV"
3 Feed and drain cock "FD"
4 "AV" venting screw
1. Use the facility system to fill the Servitec.
– After you have opened the "DC" ball valves, the vacuum spray tube
will autonomously fill if the facility system provides sufficient water.
2. Optional
– Use the feed and drain cock (3) to fill water into the Servitec.
– Connect a hose at the feed and drain cock (3) of the "VT" vacuum
spray pipe.
3. Fill the vacuum spray pipe with water.
– Air escapes via the degassing valve (2) and the water pressure can be
read at the vacuum gauge (1).
Vent the pump:
4. Turn the venting screw (1) until air or a water/air mixture escapes.
5. If required, use a screwdriver to rotate the pump at the fan wheel of the
pump motor.
CAUTION – Risk of injury due to pump start-up! Hand injury due to a
pump start-up. Switch the pump to a zero-volts state before turning the
pump motor at the fan wheel with a screwdriver.
CAUTION – Device damage. Pump damage due to a pump start-up. Switch
the pump to a zero-volts state before turning the pump motor at the fan
wheel with a screwdriver.
– Water/air mixtures are removed from the pump.
6. Re-tighten the venting screw when only water escapes.
7. Close the feed and drain cock.
Filling and venting is concluded.
 Note!
The "PU" pump must not be switched on when the Servitec is filled with
water.
 Note!
Do not fully unscrew the venting screw. Wait until air-free water
appears. Repeat the venting process until the "PU" pump is fully vented.

Vacuum test

Perform the vacuum test to ensure the proper functioning of the device.
1 Close the ball valve (1) with the dirt trap of the "DC" feed line to the spray
pipe. The second ball valve (2) in the feed line from the "DC" pump to the
system remains open.
2 Generate a vacuum in manual mode of the controller.
• Switch to Manual mode.
– For information about controller operation,  8.1 "Operator
panel",  35.
For more information about Manual mode,  9.1.2 "Manual
–
mode",  38.
3 Use "Circulate" to activate continuous degassing until the vacuum gauge
indicates a stable vacuum.
• Note the vacuum indicated on the vacuum gauge.
4 After 10 minutes, check again the "PI" vacuum gauge (1). The pressure
must not change. If the pressure has increased, check the device for leaks.
• All screw connections at the "VT" vacuum spray pipe.
• The "DV" degassing valve at the "VT" vacuum spray pipe.
• The venting screw at the "PU" pump.
 Note!
Repeat steps 2 to 4 until no further pressure rise is observed.
5 After the vacuum test has been concluded successfully, open the ball valve
with dirt trap.
6 If the controller displays the "Insufficient water" error message,
acknowledge the message with "OK".
 The vacuum test is completed.
 Note!
The obtainable vacuum corresponds to the saturation pressure at the
existing water temperature.
• At 10 °C, a vacuum of approximately -1 bar can be obtained.

Use the device to fill the facility system with water

Optionally the device can be used to fill the facility system with water.
These prerequisites must be met:
• Facility system with a water content of less than 3000 litres.
• Facility system with pressurisation via a static expansion vessel.
Proceed as follows:
1. Open the "WC" make-up line.
– Open all shut-off devices between the make-up connection the
vacuum spray pipe.
2. Set the controller to "Magcontrol".
For the "Magcontrol" make-up variant,  10.1.1 "Customer menu",
–
 39.
3. Switch the controller to Manual mode.
For Manual mode,  9.1.2 "Manual mode",  38.
