IT IS RECOMMENDED THAT THE CONSOLE MODEL
FREEZE DRYER BE SECURELY ATTACHED TO THE FLOOR
AFTER IT IS LOCATED WHERE IT WILL BE USED. THIS
WILL PREVENT ACCIDENTAL TIPPING AND POSSIBLE
INJURY. SEE INSTRUCTIONS IN CHAPTER 3 GETTING
STARTED.
Refer to Appendix C: Freeze Dryer Specifications for dimensional drawings of the
Freeze Dryer. The space for benchtop models must be large enough to
accommodate the vacuum pump, which will be used with the Freeze Dryer.
Vacuum Pump Requirements
A vacuum pump must be provided by the user. A vacuum pump with a
displacement of 86 liters per minute and 0.002 mBar ultimate pressure is adequate
for most samples. The inlet fitting on the vacuum pump must be suitable for 3/4"
ID vacuum hose, which is provided. It is recommended that the vacuum pump is
equipped with an exhaust filter to minimize oil mist exhausting from the vacuum
pump. The operating vacuum level may be set on the Freeze Dryer. The higher
the pressure is set, the more likely it is that oil mist will be exhausted.
Vacuum pumps used with 115V models should be equipped with an 115V, 15
Amp NEMA 5-15P plug. Vacuum pumps used with 230V models should be
equipped with a reverse IEC plug. This plug is included with 230V models. This
will allow the vacuum pump to be plugged into the receptacle on the back panel of
the freeze dryer. See Appendix D: Freeze Dryer Accessories for vacuum pumps
available from Labconco.
Chamber or Manifold Requirements
A freeze drying chamber is included. This allows samples to be attached to the
Freeze Dryer. See Appendix D: Freeze Dryer Accessories for other available
chambers and manifolds.
