1.2 General Recommendations
Intended Use
Helmer ultra-low freezers are intended to provide a controlled temperature environment at ultra-low temperatures required for the
storage of biological materials, pharmaceuticals, and reagents used in a research or clinical laboratory.
The devices referenced in this manual are intended to be operated by personnel who have procedures in place for meeting FDA,
AABB, or any other applicable regulations for the processing and storage of biological materials, pharmaceuticals, and reagents.
General Use
Allow freezer to come to room temperature before switching power on.
During initial startup, the high temperature alarm may sound while the freezer reaches operating temperature.
NOTE
This unit is not a “rapid-freezing” device. Freezing large quantities of liquid, or high-water content items, will temporarily
increase the chamber temperature and will cause the compressors to operate for a prolonged period of time.
Initial Loading
Allow chamber temperature to stabilize at the setpoint before storing pre-frozen product.
Product Loading Guidelines
When loading your freezer, take care to observe the following guidelines:
♦ Never load freezers beyond capacity.
♦ Always store items within shelves.
