Scheduling Oil Changes
After clean oil is loaded into the vacuum pump and all necessary connections have
been made between the vacuum pump and the freeze dryer, perform a full capacity
test cycle.
Have a qualified technician check the oil after the test cycle. If the oil appears dirty,
change the oil after every use. If the used oil appears clean, change the oil after the
next two uses or cycles. If the oil remains clean after two cycles, change the oil after
the next four cycles. Continue to monitor the vacuum pump oil after each cycle until a
change of condition is noted or a period of one month has elapsed. If the oil remains
clean after several cycles, changing the oil once per month may be sufficient.
Vacuum Tubing and Gaskets
Inspect tubing and gaskets periodically for signs of wear. Check gaskets by removing
and inspecting interior surfaces for potential problems. A light coating of vacuum
grease on the exterior surfaces will protect gaskets and tubing. Reapply grease as
needed.
