Attention: Operation of the single centrifuge 2 is possible only in emergency
           situations ( break-down of separator 1)

On the separator diagram:

1.  Open the valve 3, 4, 5, 6, 10, 12, 13, 14   ( close valves 7, 8, 9, 11  )
    Attention : regulating valves 12 and 13 should be totally open  
2.  Release brake of  centrifuge 2 ( off position ) 

On the panel control:

3.  Set the "Supply pump" switch to position I,
4.  Set "Sludge tank pump" to position Auto

On the timing unit:

5.  Set " Main switch" to position I
6.  Push the button "Lamp control" in order to check whether all signal lamps
    are in proper condition.
7.  "Centrifuge 2 " switch on position I
    Attention : LED - TA  lights indicating low fuel oil temperature - press
                push-button "Alarm confirmation"
 
On the panel control:

8.  Set "Pre-heater 2" on position I,
    Attention: It is possible to turn on the pre-heater only when centrifuge
               is running.

On the timing unit :
	
9.  Switch "Purifier/Clarifier" to position Cl
10. Switch "Automatic control" to position 0
11. Set ts separation time interval between total sludge discharges (depends
    on the level of fuel oil contamination) - for example: 10 min
12. Set sec time within the adjustment range: 0.01-1.00 seconds
    for example: 0,50 sec (the bowl may open in case the time set is too long)
13. Set xe  counter for selection of the total number of sludge discharges 
    after which flushing is to be carried out ( 1 - 9 ), for example: 4
14. Switch on "Displacement"  to position 0
15. Once the bowl revolution has been attained (check current gauge indicator
    - current should drop to about 7 A) turn switch "Centrifuge program " 
    to position I (confirmed by LED -  ~ continuous green light)
    Attention: Centrifuge program may be switched on after reaching proper 
               fuel oil  temperature - signalled by LED TA turning off)
16. After centrifuge program initiation the centrifuge is automatically 
    discharged (LED P will light confirming discharge process realisation)
17. Switch on "Displacement" to position I (fuel oil displacement is applied
    for the purpose of fuel oil discharge from the bowl before sludge discharge
    takes place - fuel oil returns to the settling tank - it is not directed to
    the sludge tank)  
18. Set "Flushing" to position I (this option is applied for additional bowl 
    flushing with water after a determined number of sludge discharges - xe ) 

On the diagram:

19. Set fuel regulating valves 12 and 13  for required flow and pressure value
    (pressure equal to about 0,3 bars - flow capacity equals to about 500 l/h)
