Chapter 2: Prerequisites
Product Service: Domestic 1-800-522-7658, International 816-333-8811
Location Requirements
The Freeze Dryer should be located in an area that provides an
unobstructed flow of air around the cabinet. This air cools the
refrigeration system. The refrigeration system draws air through
the rear panel and exhausts it through the sides. A minimum of 3"
must be allowed between the back and both sides of the Freeze
Dryer and adjacent wall surfaces. Restriction of airflow during
operation could adversely affect performance.
Refer to Appendix C: Freeze Dryer Specifications for dimensional
drawings of the Freeze Dryer. The space 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.
Vacuum pumps used with 115V models should be equipped with a
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 or manifold is not included and must be
purchased separately. These allow samples to be attached to the
Freeze Dryer. See Appendix D: Freeze Dryer Accessories for
available chambers and manifolds.
