Chapter 2: Prerequisites
Electrical Requirements
The Freeze Dryer requires a dedicated electrical outlet.
This outlet requires a 20 Amp circuit breaker or fuse for
models rated at 115V (60 Hz). An outlet equipped with
a 15 Amp circuit breaker or fuse is required for models
rated at 230V (50/60 Hz). 115V models are equipped
with a 20 Amp NEMA 5-20P plug. 230V models are
not equipped with a plug. It will be necessary to install
a plug to match the available receptacle.
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 grill on the
front panel and exhausts it through the back. A
minimum of 3" must be allowed between the back of
the Freeze Dryer and adjacent wall surfaces.
Restriction of airflow during operation could adversely
affect performance.
Vacuum Pump
Requirements
A vacuum pump must be provided by the user. A
vacuum pump with a displacement of 150 liters per
minute and 0.2 x 10
-3
mBar blank off 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.
