***Available for devicelink enabled TSX ULT Freezers.
→ Refer to our “Get ready for your new ULT” document to get started.
→ ULT Freezers are designed to operate between -50°C and -80°C. They are “tuned” to operate most efficiently between -70°C and -80°C since this is the most common customer operating temperature. Running at warmer temperatures will create more internal temperature swings since the system will be turning on and off more often.
→ Connect your freezer in five easy steps. The connectivity mechanism in your Thermo Scientific Ultra-Low-Temperature Freezer works with most enterprise networks and is designed to be set up in minutes.
→ -30°C units are auto defrost units. We recommend operating at -30°C for a -20°C requirement as there will be slight increases in temperature during the defrost cycle. The units are designed with a smart defrost system to minimize fluctuations, however, there will be some slight increase.
→ Check the set points and alarms set points for your unit. Factory settings are recommended to allow for temperature fluctuation before alarms are triggered.
→ Minimize the amount of door openings and time of door openings.
→ Maintain a full freezer. If the racks in your freezer aren’t full, use styrofoam blocks to stabilize temperature.
→ Refer to the user’s manual for HID card programming.
→ Call Unity Lab Services technical support for fastest assistance for your unit.
→ Keep it clean
→ A full freezer is a happy freezer
→ Stay ahead of frost and ice
→ Defrost annually
→ Have a plan
→ Completely clean the unit if it has been in storage.
→ Inspect the unit for any issues with the door seals and alignment.
→ Plug in the unit and allow it to pull the temperature down.
→ Once the unit is down to it’s set point, let it operate for a couple of days to ensure all systems are correctly operating prior to introducing samples.
→ Once the unit is determined it is operating properly, it should be loaded one shelf at a time, starting at the top.
