Before you install your freeze dryer, you need to prepare your site for
installation. Carefully examine the location where you intend to install your
freeze dryer. You must be certain that the area is level and of solid
construction. An electrical source must be located near the installation site.
Carefully read this chapter to learn:
•
the electrical supply requirements.
•
the vacuum pump requirements.
Refer to
Appendix C: Freeze Dryer Specifications
for complete freeze dryer
electrical and environmental conditions, specifications and requirements.
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). The power cord on 115V models are equipped with a 20
Amp NEMA 5-20P plug. The power cord on 230V (60 Hz) models is
equipped with a NEMA 6-20P plug. The power cord on 230V (50 Hz)
models is equipped with CEE 7/7 plug. If this does not match the available
receptacle, remove this plug and replace it with an approved plug of the
suitable style.
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.
