Vacuum Test - Reflex Servitec 35 Mode D'emploi Original

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.
CA UTION – 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.
CA UTION – 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 Servitec.
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 with the manual mode of the controller.
• Press "Manual" on the controller's operator panel.
• Use the "Back" toggle button to select "SE" system degassing at the
operator panel.
– The pump will start after a time delay of 50 seconds.
3 Use the "Back" toggle button to switch off "SE" system degassing after the
pump runs for 10 seconds.
• Note the vacuum indicated on the vacuum gauge.

4 Observe the "PI" vacuum gauge (1) for approximately 10 minutes. The
pressure must not change. If the pressure has increased, check the Servitec
for leaks.
• Check all screw fittings at the "VT" vacuum spray tube for leaks.
• Check the vent screw at the "PU" pump for leaks.
• Check the "DV" degassing valve at the "VT" vacuum spray tube for
leaks.
Note!

Repeat steps 2 to 4 until no further pressure rise is observed.
5 After a successful vacuum test, open the ball valve with dirt trap.
6 If the controller displays the "Insufficient water" error message, confirm
with "Quit".

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.
7.7 U se the device to fill the facility system with water
In systems with a water volume less than 3000 litres and a pressure maintenance
with diaphragm-type expansion vessels, the Servitec may be used for filling
using degassed water. Thus, the oxygen content and the content of free gases is
reduced for commissioning.
Set the controller to the following operating modes:
• "Magcontrol" automatic make-up, see chapter 8.2.1 "Customer menu" on
page 36 .
• Manual operation, see chapter 8.1.2 "Manual mode" on page 36 .
– "NE" make-up degassing mode.
The controller calculates the required filling pressure. As soon as this value has
been attained, the controller automatically stops the filling process. If the
maximum filling time (10 hours by default) is exceeded, the system aborts the
make-up process with an error message. After the cause has been found,
acknowledge the error message by pressing "Quit" at the controller's operating
panel and continue with the filling process, see chapter 8.2.4 "Meldungen" on
page 18 . After filling is completed, you must vent the system to ensure proper
circulation through the entire system.
Note!

Monitor the system for the entire automatic filling process.
Note!

Filling the system with water is not part of the deliverables of the Reflex
Customer Service.
7.8 P arametrising the controller in the Customer menu
System-specific values can be corrected via the customer menu. In the course of
initial commissioning, the factory settings must be adjusted for the system-
specific conditions.
Note!

For a description of the operation, see chapter 7.2 "Setting the minimum
operating pressure for Magcontrol" on page 31 .
