Refer to the following if your Freeze Dryer fails to
operate properly. If the suggested corrective actions do
not solve your problem, contact Labconco for
additional assistance.
Labconco Freeze Dry Systems should reach a vacuum
of 133 x 10
-3
mBar within 10 minutes and should
achieve an ultimate vacuum of 33 x 10
-3
mBar within
18 hours. If the Freeze Dryer does not obtain a
satisfactory vacuum, perform the following
maintenance tests.
I. Vacuum Pump
First make sure that the vacuum pump operates. If it
fails to operate, check the electrical connections of the
Freeze Dryer to the power source and then check the
electrical connection of the vacuum pump to the Freeze
Dryer. If the vacuum pump has a power switch, make
sure that it is turned on. If the vacuum is not adequate
when the vacuum pump is operating, proceed with the
following steps:
1. Check the oil and ensure it is clear and clean. If
the oil looks cloudy or has any particulates,
replace the pump oil. Sometimes it may be
necessary to flush the pump with clean oil
several times. To flush the pump, run the pump
5 to 10 minutes to allow the oil to warm up.
Drain the oil and refill with clean oil. Repeat as
necessary.
