Maintenance
Any maintenance or repair of this product, other than that specified within this user manual,
must be carried out by Genevac personnel (or approved representatives of Genevac) using
only approved spare parts.
Warning: Risk of contamination. Solvents can condense in the exhaust line.
Wear suitable personal protective equipment when carrying out maintenance
procedures, this is particularly important for HCl compatible systems.
Recommended practice
Before use
Check / empty the pump exhaust catch pot as necessary
Check / drain the condenser
Check the condition of sample holders and swings (where used) before every use.
After use
Drain the condenser at the end of every run. Where possible, defrost and drain should be
set up to occur automatically; where this is not possible, initiate the defrost and drain cycle
manually.
Depending on the type of solvent used, it may be advisable to clean the evaporation
chamber and sample holders following every use; cleaning should be performed if any trace
of solvent is evident on the inside of the evaporation chamber, or if any solvent is spilled.
For further instructions, refer to the following sections: General cleaning and Sample
holders.
Periodic maintenance
Check the condition of the exhaust hose and waste solvent drain tubes:
Make sure the exhaust hose takes solvent vapours away from the system safely. Avoid
forming U-bends in the pipe as this could cause condensed solvent to gather and block
the line.
Make sure that waste solvent drains freely. The drain hose should not have any sharp
bends or up-hill sections that could impede drainage of the waste solvent.
For high boiling point solvents such as DMSO, NMP, DMF and DMI the best evaporation
rates are achieved at pressures better than 0.5 mbar; a gradual decline in system
performance may not be noticed if it occurs over a period of time. In order to monitor system
performance, Genevac recommend keeping a log of the time taken for the system to reach
full vacuum and the ultimate vacuum achieved.
If any deterioration in performance is noticed, firstly check that all users are adhering to the
Before use and After use checks, and General cleaning instructions listed above. Also
check the security of all clamped joints (but do not over tighten).
