The device is not designed for use in medical applications in accordance with DIN EN 60601-1 and IEC 601-1. If this operating manual is lost, contact LAUDA Service. You can find the contact information here Ä Chapter 13.4 “Contact LAUDA” on page 71.
Control element 2.0.509 Main battery monitor 1.09 1.5 Intended use The LAUDA Mobifreeze M 270 is a mobile ultra low temperature chest freezer designed for industrial use. The temperature range extends from -50 °C to -86 °C. Mobifreeze 7 / 93...
The device is designed exclusively for the temperature control, storage and transport of non-hazardous substances, such as chemicals, pharma- ceutical substances and medications. Only the integrated mains plug or the internal main battery may be used to operate the device. The mobile ultra low temperature chest freezer may only be moved by hand.
The contents of the compartment must be adapted to the transport conditions and filled/secured accordingly. Minimize the time that the chest freezer spends in cold ambient condi- tions. 1.11 Materials All parts of the device are manufactured from high-quality materials adapted to withstand the operating temperature.
Forklift driver The forklift driver must be 18 years old or over and have physical, mental and character-related qualities that are suitable for driving industrial trucks that have a driver's seat or driver's cab. Furthermore, the forklift driver has been trained to drive industrial trucks that have a driver's seat or driver's cab.
Safety shoes Safety shoes are worn to provide protection against heavy falling objects and prevent slipping on slippery surfaces. They also protect the feet when removing exterior protective panels. 1.17 Safety fittings on the device 1.17.1 Alarm message In the event of a malfunction, an alarm is triggered.

1.17.5 Overtemperature alarm The overtemperature protection is a warning device that is activated when the temperature in the refrigeration compartment exceeds the specified upper limit. This information is shown on the Touch operating unit display. An acoustic alarm also sounds (1 second on – 1 second off). 1.17.6 ...
1.20 Structure of warnings Dangerous A warning of "dangerous" indicates an immediately dangerous situation. If this warning is not observed, then death or severe, irreversible injury could occur. DANGER! Type and source Consequences of not following instructions Measure 1 Measure...
If you discover that the transport packaging is damaged: Place/store the device in a well-ventilated location with no sources of ignition. Do not operate the device. Contact LAUDA Service. WARNING! LiFePO4 battery damaged during transport Fire, breakages, heat, leaks Protect the battery system from damage.
Also notify the LAUDA Service department immediately. Refer to Ä Chapter 13.4 “Contact LAUDA” on page 71 for contact details, and place/store the device in a well-ventilated location with no sources of ignition.
The certificate can be found in the "General" chapter of this operating manual, see Ä Chapter 13.7 “UN38.3 Test Report for LiFePO4 bat- tery” on page 74, and downloaded in PDF format from www.lauda.de in the "Service" area: https://www.lauda.de/en/services/download-center/ filter/default/mobifreeze.
