Replace the Manifold
Warning
»
The nozzles may have come into contact with hazardous
samples. Avoid contact.
»
Ensure not to bend any of the nozzles. If a nozzle is bent, it is
recommended that the manifold is replaced.
»
Do not touch the inside of the gas heater. Touching may leave
residues that can contaminate the following runs.
»
Always turn off the system, disconnect the power cord, and let
the system cool down before performing maintenance.

Potential biohazard. Use appropriate PPE if the system has
processed biohazardous samples.
There are three different manifolds available. The manifold
is selected according to the well plate or rack to be used.
For further information, see "Manifolds" on page 5.
1. Remove the fume shield. Loosen the fume shield set screw,
slide out the fume shield and remove it. See Figure 16.

Remove the fume shield.
2. Use the Torx T20 key (P/N 411886) supplied with the system
to remove the two screws that secure the manifold to the
gas heater, see Figure 17. Ensure that the manifold is held in
position while the last screw is removed.
3. With a steady grip, remove the manifold.
Note:
Do not hold the manifold by the nozzles as this might bend
the nozzles.
4. Examine the new manifold and the gasket for debris. If there
is debris between the manifold and the gas heater, gas
leaks can occur.
Note:
Do not touch the inside of the gas heater. Touching may
leave residues that can contaminate the following runs.
5. Use the 2 pins on the gas heater to guide the new manifold
in position. See Figure 17.
6. Secure the new manifold with the
screws.
Note:
Ensure that the screws are tightened by hand using the
Torx T20 key.
7. Install the fume shield.
8. Finger tighten the fume shield set screw.
9. Clean the removed manifold and let it dry (see "Clean the
Manifolds" on page 20). Store the replaced manifold in a
dust free environment.
10. Check that the user interface is set to the correct manifold,
see "Common Settings" on page 8.

Remove the 2 screws and the the manifold.
Set the Pressure
Warning
»
To avoid injury to person or damage to the system, do not
exceed the maximum inlet pressure of 6.5 bar (0.65 MPa,
94 PSI).
To set the appropriate pressure, see TurboVap
