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. The Triad Freeze Dryer must be placed on a work
surface or table that will support over 400 lbs.
Refer to Appendix B: Freeze Dryer Dimensions for dimensional drawings.

Vacuum Pump Requirements

A vacuum pump must be provided by the user. A vacuum pump with a
displacement of 98 liters per minute and 0.007 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 vacuum set point, the more likely it is that oil mist will be exhausted.
Vacuum pumps should be equipped with a reverse IEC plug (included with 230V
pumps purchased from Labconco). This will allow the vacuum pump to be
plugged into the receptacle on the back panel of the freeze dryer.
