Bumping
Bumping is unpredictable and can occur with any solvent mixture; it can cause cross
contamination between samples and can leave damaging deposits on the IR lamp lenses.
Avoidance is straight forward; simply select the
Dri-Pure
option from the
Pressure Control
Regime
drop down menu on the
Run Edit
screen. This sets a high rotor speed and avoids
super-heating the samples by reducing the pressure in the vacuum chamber by gradual
increments. Evaporation begins progressively and samples are contained due to the higher
centrifugal force.
Opening the door without power
In the event of power failure, the vacuum system vents
automatically, the rotor may take up to two minutes to
stop spinning.
Once the rotor is stationary and the vacuum system is
at atmospheric pressure, use the 5 mm Allen key
(supplied) to release the upper and lower door lock
release screws as shown.
Unscrew the upper release screw and remove it.
Unscrew the lower release screw as possible, this
disengages the lock but the screw cannot be removed
until the door is opened.
Manually pull the door to open it.

Circuit breakers
Resettable mains power circuit breakers are located
above the vacuum pump.
If a circuit breaker trips, it may be the result of an
electrical failure. If a breaker trips repeatedly,
contact Genevac service for assistance.
