u
If faults occur, switch off the device immediately, unplug the power cord and
inform the operator.
u
Do not continue to use devices that are damaged.
2.5.2
Damage to the ice condenser
Damage to the ice condenser leads to coolant leakage and failure of the instrument.
u
Wait until the ice is completely thawed.
u
Do not use mechanical means to remove ice from the ice condenser.
2.5.3
Glass and acrylic breakage
Broken glass and acrylic can cause severe cuts.
Damaged glass and acrylic components may implode if subjected to a vacuum.
Minor damage to the ground joints impairs the sealing effect and may therefore
diminish sublimination capacity.
u
Handle the flask and other glass and acrylic components carefully and do not
drop them.
u
Always place the flasks in a suitable holder when they are not mounted on the
Lyovapor™.
u
Always visually inspect glass and acrylic components for damage every time they
are to be used.
u
Do not continue to use glass and acrylic components that are damaged.
u
Always wear protective gloves when disposing of broken glass and acrylic.
2.5.4
Low internal pressure
Evacuating the system reduces the pressure in the drying chamber. This reduced
pressure can cause glass and acrylic components to implode.
u
Make sure that all glass and acrylic components are free of damage.
2.5.5
Cold and hot surfaces
The condenser coil and probes can be extremely cold. Heatable shelf areas can be
extremely hot. If touched, hot and cold surfaces can cause skin burns.
u
Do not touch cold or hot surfaces or liquids and/or wear suitable protective
gloves.
2.6
Personal protective equipment
Depending on the application, hazards due to heat and/or corrosive chemicals may
arise.
u
Always wear appropriate personal protective equipment such as safety goggles,
protective clothing and gloves.
u
Make sure that the personal protective equipment meets the requirements of
the safety data sheets for all chemicals used.
2.7
Modifications
Unauthorized modifications can affect safety and lead to accidents.
u
Use only genuine BUCHI accessories, spare parts and consumables.
u
Carry out technical changes only with prior written approval from BUCHI.
