Thermo Scientific Jewett Blood Bank Refrigerators
Installation and Operation
TEMPERATURE CONTROL
This refrigerator uses a Dixell XR60 temperature control:
Control operation is described in detail on the following three insert pages.
The operating temperature setpoint for all blood bank refrigerators is pre-set to 4ºC at the factory and should
not normally be changed for blood storage applications. If you want to adjust any control parameters, it is
advisable to contact Technical Service before doing so.
CAUTION!
Unless a front panel control option has been specified, the control panels for BBR blood
bank refrigerators are located inside a junction box on the back of the refrigerator. To access the
control, remove the four screws and carefully remove the cover. Be sure to avoid touching any
component inside the junction box other than the control panel.
WARNING!
Making control adjustments inside the junction box involves potential contact with line
voltage and should only be performed by a qualified service technician.
