3.11 Measures to be taken to ensure safe operation of the freeze-dryer
In order to ensure the safe operation of the freeze-dryer, please comply
with the following points prior to every freeze-drying process:
Set-up, connection and operation
• Ensure that the freeze-dryer was set up and connected properly (see
chapter 5 - "Set-up and connection").
• Check the freeze-dryer and the accessories before every start-up for
any visible signs of damage.
• Do not hit or move the freeze-dryer during its operation.
• Do not lean against or rest on the freeze-dryer during its operation.
• Stop the freeze-dryer immediately in the event of a malfunction.
Eliminate the malfunction (see chapter 7 - "Malfunctions and error
correction") or contact the after-sales service of Firma Martin Christ
Gefriertrocknungsanlagen GmbH (see chapter 7.3 - "Service contact").
• Ensure that all repairs are performed only by authorised and specialised
personnel.
Fire prevention
• Fuses protect certain electrical circuits within the freeze-dryer against
over-current conditions. Always use fuses of the same type and rating.
Safety area
• Maintain a safety distance of at least 30 cm (12 inches) around the
freeze-dryer.
• Do not store any dangerous goods in the safety area of the freeze-
dryer.
• Do not place any dangerous material, e.g. glass vessels containing
liquid substances, within the safety area of 30 cm around the freeze-
dryer. Spilled liquids may get into the freeze-dryer and damage the
electrical or mechanical components.
• Do not stay in the safety area longer than what is absolutely necessary
for the operation of the freeze-dryer.
Accessories
• Do not use the freeze-dryer with accessories that shows signs of
damage.
• Only use accessories that have been approved by Martin Christ
Gefriertrocknungsanlagen GmbH. This does not apply to commercially
available freeze-drying vessels made of glass. We explicitly warn
against the use of equipment of poor quality! Breaking glass or bursting
vessels can cause dangerous situations during the freeze-drying
process.
