6.1
Initial start-up
WARNING
Risk of injury caused by consequences of transport damage, or
improper connections (e.g. escaping media).
Leaks after the transport, set-up, and connection of the freeze-dryer may
lead to problems, e.g. the escape of media (depending on the
configuration of the freeze-dryer, e.g. refrigerant, heat transfer medium,
hydraulic oil, nitrogen, hydrogen peroxide, etc.), at a later time during the
initial start-up of the freeze-dryer.
This may lead to severe damage to health or even life-threatening injuries.
• Prior to the initial start-up of the freeze-dryer, all of the supply and
disposal connections must be checked for leaks by specialised
persons.
