7. Maintenance and Cleaning
Should it become necessary to take the manifold apart (possibly infectious!) take
care to insert all sealings properly when reassembling the manifold.
Twisted or missing seals may result in a leaking manifold!
After the manifold has been cleaned, reconnect the tubing and replace it into the
instrument.
Tighten the manifold into place using the two screws, ensure that the screws are
tight.
When the manifold has been refitted, switch the instrument on and perform the
priming procedure using distilled water.
7.1.2
Exchanging the Manifolds
The instrument can be used with the following types of manifolds:
•
Normal (8, 12 and 16)
•
Normal with aerosol aspiration
Factory installation required
•
Fill verification
Factory installation required
•
Cell wash manifold (8, 12 and 16)
•
384 Well Manifold
The manifolds are fitted to the instrument using the following procedures:
1.
Lift the manifold arm.
2.
Carefully fit the manifold onto the manifold arm and ensure that the
locating pins are correctly inserted through the holes in the plate.
3.
If the manifold detection option is fitted, ensure that the manifold type
indicator is correctly fitted between the manifold type detector switches.
4.
Tighten the manifold into place using the two screws.
5.
Fit the dispensing tube onto the top connector on the rear of the manifold.
6.
Fit the aspirating tubing (marked with red rings) onto the two bottom
connectors on the rear of the manifold.
7.
If the aerosol pump option is fitted, fit the aerosol tubing (marked with
yellow rings) onto the aerosol connectors of the aerosol part.
8.
If the Fill Verification option is fitted, connect the small ribbon cable onto
the connector block on the left hand side of the circuit board in the manifold
arm.
