If the plug does not match the available receptacle, remove the
plug and replace it with an approved plug of the suitable style.
Do not use any detachable power cord that is not adequately
rated for the unit.

ADDITIONAL APPLIANCES ON THE SAME CIRCUIT MAY
CAUSE THE CURRENT TO EXCEED THE RATING OF THE
CIRCUIT BREAKER OR FUSE.
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 in through the front and exhausts it through the
rear. A minimum of 3" must be allowed between the rear and both sides of the
Freeze Dryer and adjacent wall surfaces. Restriction of airflow during operation
could adversely affect performance. Refer to
Appendix B: Dimensions
for
dimensional drawings of the Stoppering Tray Dryer.
Vacuum Pump Requirements
A vacuum pump must be provided by the user. A vacuum pump with a
displacement of 163 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 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 (included with 230V pumps purchased from Labconco).
This will allow the vacuum pump to be plugged into the receptacle on the rear
electrical panel of the Console Freeze Fryer.
