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 device 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.
7.4 Vacuum test
Carefully perform the vacuum test to ensure the proper functioning of the device.
Proceed as follows:
1. Switch to Manual mode.
• For more information about Manual mode,  8.1.2 "Manual mode",
 42.
2. Close RKH1 (control ball valve) from the system feed line in controller
"Manual mode".
3. Close MKH2 (motorised ball valve) to the tank in controller "Manual mode".
4. Close the "Safe Control" make-up valve in the make-up pipe.
5. Open the 3-way motorized ball valve in the direction of the pump/spray pipe.
6. Generate a vacuum in controller manual mode.
7. After 10 minutes, recheck the "PI" vacuum gauge. 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.
8. After successful conclusion of the vacuum test, open the ball valve (2).
9. If the controller displays the "Insufficient water" error message, acknowledge
the message via button "OK".
 Note!
The obtainable vacuum corresponds to the saturation pressure at the
existing water temperature.
–
 Note!
Repeat steps 5 to 6 until no further pressure rise is observed.
7.5 Filling the tanks with water
The following information applies to the devices:
• Control unit and primary tank.
• Control unit and primary tank and one secondary tank.
• Control unit and primary tank and more than one secondary tanks.
Facility system
Heating system
Cooling system
7.5.1 Filling with a hose
Preferably use a water hose to fill the primary vessel with water when the
automatic make-up device is not yet connected.
• Use a vented water hose filled with water.
• Connect the water hose to the external water supply and the "FD" feed and
drain cock (1) at the primary vessel.
• Check whether the shut-off valves between control unit and primary vessel
are open (supplied pre-wired in open position).
• Fill the primary vessel with water until the filling level has been reached.
7.5.2 Filling using Safe Control in the make-up pipe
1. Use the "Manual mode" button to switch to "Manual" mode.
2. Open the "WV make-up valve" and "MKH2" via the corresponding buttons
until the specified filling level is reached.
– Continuously monitor this process.
– If a high-water alarm is generated, the make-up valve "WV make-up
valve" is automatically closed.
7.6 Starting Automatic mode
 Notice!
The "ST" dirt trap in the "DC" degassing line must be cleaned after the
expiry of the continuous degassing time at the latest,  10.3.1 "Cleaning
the dirt trap",  49.
 Note!
The commissioning process is now concluded.
