5. Operation
5.1 – Responsible Operation
Responsibility for freezer operation should be part of the policy and procedure
documentation or guidelines for the clinical, laboratory, or other activity for which
the freezer is used. Safety requirements are integral to these responsibilities. Use
this product only in the way described in the product literature and in this manual.
Before using it, verify that this product is suitable for its intended use. If this
equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
5.2 – Handle Operation
The Stirling Ultracold handle is designed for one-handed operation. To open the
freezer, rotate handle towards the user through an angle of about 90°. To engage the
Power-Release, gently apply firm, downward pressure on the handle while in its open
position. The Power-Release assists when the freezer door is adhered to the gasket
after long periods of non-use as well as when air pressure is not yet equalized. To
close, with handle in the horizontal position, push door to closed position and return
the handle to its original vertical position.
