Vacuum Pump Connection

A vacuum pump (as described in Chapter 2: Prerequisites) is required to operate
your Freeze Dryer properly. The Freeze Dryer is equipped with a 3/4" ID vacuum
hose for connecting the collector chamber to the vacuum pump.
!
1. Place the vacuum pump near the benchtop Freeze
Dryer.
2. Remove protective caps from inlet and outlet
ports.
3. Some vacuum pumps have inlet fittings that clamp
to the pump. Place the centering ring with filter
screen on the inlet fitting.
4. Place the hose barb fitting on top of the centering
ring and secure with the clamp.
5. CHECK THE VACUUM PUMP OIL LEVEL.
Fill the pump with oil so the level is between
the lines on the sight gauge on the end of the
pump housing.
6. Attach one end of the vacuum hose to the port
on the back of the Freeze Dryer and the other
end to the inlet port of the vacuum pump with
the hose clamps provided. If necessary, cut
the hose to proper length to allow for gentle
bends without kinks.

level.
