Vacuum Pump Connection
A vacuum pump as described in Chapter 2: Prerequisites is
required to operate your Freeze Dry System properly. The Freeze
Dryer is equipped with a 3/4" ID, heavy wall, vacuum hose for
connecting the collector chamber to the vacuum pump.
Make certain that the oil in the vacuum pump is
at the proper level.
Remove the front stainless steel panel or lower rear panel from the
Freeze Dryer. The front panel is removed by placing a flat blade
screw driver into the rectangular hole in the center of the kick
panel. Pivot the handle downward to disengage the latch and
simultaneously pull the lower panel forward.
Place the vacuum pump inside the cabinet. Connect the vacuum
pump power cord to the receptacle on the back of the cabinet
labeled “vacuum pump.” Models rated for use on 230V have a
reverse IEC connector for attaching the vacuum pump power cord.
A plug is supplied that can be installed on the vacuum pump power
cord if necessary. If the vacuum pump has an off/on switch, turn
the switch on. The vacuum pump will be controlled by the Freeze
Dryer. Connect the vacuum pump inlet port to the vacuum tube
inside the cabinet near the front with the vacuum hose and clamps
provided. If necessary, cut the hose to proper length to allow for
gentle bends without kinks.
