3.7 Position the System
After completing the various connections, the system can be
moved to its operating position. Turn the system so that the
operator can access all of the front view features and controls
(Figure 1-7). Use care not to damage the connections, tubing,
and cables while moving the system.
CAUTION
Ensure that the Combi Flash Rf has at least 3 cm (1.25") of air
space behind it for ventilation.
Position the solvent and waste containers as necessary.
Note
When using higher-density solvents such as dichloromethane
(DCM), place the solvent container level with or above the
Combi
Flash Rf system. Placing solvent containers below the level
of the Rf can contribute to decreased flow due to the high vapor
pressure of DCM. This problem becomes more pronounced as the
ambient temperature increases.
Vacuum or
pressurized air
applied to the outlet
end of the drain
tube must exist at
the top shelf drain
hole.
