Note
Drain tubing is not required on the Pump Drain port.
Discontinue use of the CombiFlash Rf
at the Pump Drain. Contact Teledyne Isco technical service for
assistance with correcting the leak.

2.9 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.
Ensure that the CombiFlash Rf
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
CombiFlash Rf
level of the Rf
vapor pressure of DCM. This problem becomes more pronounced
as the ambient temperature increases.
Note
When using higher-density solvents such as dichloromethane
(DCM), ensure that the waste container is no more than 3 feet
below the supply solvent levels. Placing solvent containers above
the system and waste containers on the floor may cause the
internal check valves to open and allow solvent to flow through the
system when in the standby state.
