Installation
15. Attach the four lifting handles to the system; see Figure 2.
The handles are supplied with the system.
Figure 2. The four lifting handles supplied with the system must be used
when moving the system.
16. The system weighs 75 kg (165 lbs). Carefully lift the system
using the four lifting handles and place it on a trolley that
can support the weight of the system. Four persons are
required when lifting the system.
17. Move the trolley and the rest of the equipment (the pipette
tip waste bin, waste reservoir, vacuum pump (if used),
solvent bottles, etc.) to the new location.
18. Carefully lift the system and place it in a well-ventilated
fume hood or on a bench. Four persons are required when
lifting the system. Place the system so that the mains switch
is easy to access.
19. If the system is not placed in a fume hood, connect the outlet
of the Extrahera top ventilation to a ventilation system:
a. Connect an air duct adapter from Biotage to the outlet of
the Extrahera top ventilation.
b. Connect a ventilation tube between the air duct adapter
and the exhaust. The outer diameter of the air duct
adapter is 159.0 ± 0.3 mm (6.26" ± 0.01") and the inner
is 152.7 ± 0.3 mm (6.01" ± 0.01"), i.e. the 160 mm tube
should be mounted outside the air duct adapter and the
6" tube on the inside of the air duct adapter. Ensure that
the tube cannot be blocked.
20. It is important that the system is not tilting backward.
Level the system by adjusting the height of the feet. There is
a built-in spirit level in the bottom of the system, in the front
left corner. See Figure 3.

left corner.
21. Place the solvent bottles on the side of the system and
insert the solvent inlet lines into the correct bottles.
Ensure to use appropriate caps to prevent harmful solvent
vapors from escaping and the contents from being spilled.
22. Place the waste reservoir on the side of the system and
connect the waste outlet tube and vacuum to it; see Figure 4.
If using a vacuum pump, ensure that the vacuum pump
fumes are directed into a proper ventilation system.

23. Before connecting air and/or nitrogen to the system,
the pressure head must be removed to protect it from
contamination:
a. Remove the two screws holding the pressure head to the
pressure unit; see Figure 5.
Figure 5. The two screws attaching the pressure head to the pressure unit.
b. Remove the pressure head by pulling it down and then
pulling it out.
Note:
If you have a system with only one gas tube
connected to the pressure head, you have to tilt the
pressure head horizontally to be able to pull it out.
c. Disconnect the gas tubes (or tube) from the pressure
head by pushing in the collar of each connector against
the fitting and pulling the tubing out; see Figure 6.
d. Put the pressure head on a clean and lint-free surface.
