A tighter range maintains a tem perature very close to the selected temperat ure at the cost of greater LN2 usage.
TW-357 REV E 31 Display Brightness DISPLAY BRIGHTNESS can be set through the menu system of the control ( MENU , 6, 3). This option changes the intensity of the display. The possible choices are 25%, 50%, 75% and 100%. About this Control ABOUT THIS CONTROL can be accessed in the menu system ( MENU , 6, 4).
TW-357 REV E 32 The DC solenoid valve requires that the battery be connected for the sy stem to work properly. If the battery is disconnected or completely discharged the valve opera tion and the control operation may be affected. In particular, if the control is calling for a fill, the sole noid will be called to open.
TW-357 REV E 33 MAINTENANCE Strainer Cleaning Instructions The container will not fill properly if the strainer is clogge d with ice or dirt. To clean the strainer, first close the supply valve to the refrigerator. Vent the fill line of all pressure. Remove and warm the strainer to am bient temperature.
TW-357 REV E 34 Cleaning Your Taylor-Wharton CryoStorage System The cryogenic vessel of all LABS CryoStorage Systems ma y need to be cleaned, and sterilized if the type of stored product is changed or the unit is taken out of service.
