8.1.6

Vacuum pump

NOTE

Please refer to the separate operating manual of the vacuum pump!

The stress of the vacuum pump in conjunction with a freeze-dryer is usually
not very high. This is why the recommendations in this operating manual
may differ from the information that is provided by the pump manufacturers.

Under normal operating conditions, the following maintenance tasks
concerning the vacuum pump must be performed at regular intervals:
• Check the oil level of the vacuum pump once per week. If necessary,

top it up with oil.

• Check the running pump for any unusual noise.
• Ensure that the pump has reached its operating temperature prior to

changing the oil.

• Perform the first oil change after approximately 100 operating hours.
• The other oil changes depend on the operating conditions. In general,

an interval of 500 to 1,000 operating hours is sufficient.

• Please contact the Christ service department if you have any queries

(see chapter 7.3 - "Service contact").

8.1.7

Exhaust filter (oil mist separator)

NOTE

Please refer to the separate operating manual of the vacuum pump and
the exhaust filter!

The oil mist that is emitted by the vacuum pump in quantities that depend
on the working pressure must be led to the outside or to an exhaust hood
or similar. If this is not possible, the pump must be equipped with an
exhaust filter (oil mist separator).
• Observe the liquid level in the collecting vessel of the filter.
• Remove the condensate in time (please refer to the information

provided by the manufacturer in the separate operating manual).
