FeaTURes OF The sU105U FReezeR.8-11 Free-Piston Stirling Engine (FPSE).8 Cabinet Design Features. M150A free-piston Stirling engine (FPSE) technology to provide high effi- ciency, deep-temperature cooling.
1.2 – Applications The SU105U freezer is designed for long-term storage of materials with ultra low, well-regulated temperature storage requirements, such as found in clinical and bio- logical laboratory and testing settings. Please note that precautions and safety instructions are part of each section of the manual, and must be observed to avoid damage to the freezer or harm to its users. Two Model SU105U cabinets stacked. Shown with optional stacking adapter. Two resistance temperature detectors (RTDs) measure the internal cabinet tempera- ture of the SU105U.
One provides input to the FPSE controller and the other provides input for the Swift GUI display and for reporting and logging. The display RTD may be user calibrated through the Swift GUI.

˚ C 03.2012.1 Operating Manual: Ultra Low Storage. 2.7 – Options. Stacking Adapter When stacking two Stirling Ultracold SU105U FPSE Ultra Low Temperature (-86°C) Freezers, a stacking adapter is required. The Stacking Adapter consists of two (2) plates and twelve (12) screws. 2.7.1 – Adapter Installation Procedure 1. Safety Precautions Potential hazards associated with use of the SU105U freezer may impact the safety of persons in the workplace in which the freezer is installed. This includes persons who operate the freezer, and other personnel in its vicinity.
The freezer itself may also be damaged or its warranty voided by improper operation or usage. Safety Precautions. When removing the power cable, hold onto the plug and not the cable. Do not block the air intake or air discharge vents used by the FPSE (See pictorial on Page 10 for locations.). Ultra low temperature freezers are different from home freezers in that at -86°C frostbite can occur instantly. Unpacking and Installation Verify the SU105U freezer shipment by uncrating the freezer and included items, inspecting them for damage during shipping, and compare the items to the packing list for completeness.
