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.
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).
