Original instructions
Service Vacuum Pump
The vacuum pump normally plugs into the vacuum pump electrical receptacle on
the back of the Freeze Dryer. When the Freeze Dryer has accumulated a total of
1000 operating hours, an alert will be activated. It may be necessary to service the
vacuum pump more frequently than every 1000 hours depending on the operation
of the Freeze Dryer.
The pump oil should be regularly monitored to verify that
it is clean.
The “Set hours between oil change” can be reprogrammed from the
Settings / Maintenance screen for any value from 0 to 9999 hours.
Vacuum Leak
If the vacuum level in the freeze dryer has not reached at least 5 mbar within 30
minutes of starting the vacuum, an alert will be activated and the vacuum pump
will be turned off (if it is plugged into the Freeze Dryer vacuum pump outlet).
Vacuum Set Point
If the system is unable to achieve the vacuum set point (during Manual or Program
mode), an alert will be activated. This alert will be activated if the vacuum level is
not within 0.500 mbar of the vacuum set point in 20 minutes.
Status Email Messages
If this option has been turned on, the selected email addresses will receive
STATUS alert messages containing the current operating parameters of the Freeze
Dryer. Status alert messages will not be displayed on the touch screen. The
Freeze Dryer can be configured to send email status alert messages from the
Settings / Alerts / Select Alerts screen.
End Point Detection (optional accessory)
An alert will be activated when the primary drying phase end point has been
detected for any of the active flask sensors connected to the End-Zone end point
detection accessory.
System Temp Variation (optional accessory)
If a Stoppering Tray Dryer accessory is connected to the Freeze Dryer this alert
will be activated if the system temperature varies more than ± 2°C from the Shelf
Temp Set Point.
System Temp Set Point (optional accessory)
If a Stoppering Tray Dryer accessory is connected to the Freeze Dryer this alert
will be activated if the system temperature stabilized without reaching the Shelf
Temp Set Point.
Shelf Temp Variation (optional accessory)
If a Bulk Tray Dryer, Tray Dryer or Heated Product Shelves accessory is
connected to the Freeze Dryer this alert will be activated if the shelf temperature
varies more than ± 3°C from the shelf set point temperature.
