Installation

24. Connect a pressurized air or nitrogen supply to the 

AIR

 port 

located on the right hand side at the rear of the system using 
the pressure regulator as shown in Figure 7.
The gas connected to the 

AIR

 port is used to seal the plate/

columns. The pressure should be adjusted according to how 
many positions in the extraction plate or column rack that 
are populated. Use 6 ± 0.2 bar (0.6 ± 0.02 MPa; 87 ± 3 psi) 
for a fully populated plate/rack and lower to approximately 
4 bar (0.4 MPa; 58 psi) when 50% of the plate/rack is 
populated and 3 bar (0.3 MPa; 44 psi) when 25% of the 
plate/rack is populated.

25. Connect a pressurized air or nitrogen supply to the 

N

2

 port 

located on the right hand side at the rear of the system using 
the filter unit with a pressure regulator; see Figure 8. Set the 
pressure to 6 ± 0.2 bar (0.6 ± 0.02 MPa; 87 ± 3 psi).

26. If you have the Extrahera GLP software and you want to 

connect the system to your network, connect a network 
cable between the 

LAN

 port located on the right hand side  

of the system and your network.

27. If you have disconnected the touch screen, reconnect it by 

reversing the instructions in step 14. 

Note: 

Do not mix up the Ethernet cables. Connect according 

to the labeling on the cables and the ports (

LAN 1

 and 

LAN 2

). 

28. Connect the system to a properly grounded (earthed) power 

outlet with the correct mains voltage and frequency. 

29. Ensure that the power cord and any cables, hoses, and 

tubing connected to the system cannot come in contact with 
chemicals. Corrosives and solvents can degrade the cord/
cable insulation and dissolve the hoses and tubing. There is 
a risk of electric shock, fire, and/or equipment damage.

30. Turn on the system. The mains switch is located on the right 

hand side at the rear of the system.

32. Reconnect the gas tubes to the pressure head. Ensure that 

they are properly fastened by pulling on them and that they 
are on the left side of the bracket as shown in Figure 10.

 Ensure that the gas tubes are on the left side of the highlighted 

bracket.

33. Put the pressure head back in place using the two screws. 

Do not overtighten the screws.
