Page 7: Using The Freezer Cabinets
The freezer cabinet must not be operated in hazardous areas. LAUDA Freezer Cabinets used in laboratories are not classified as medical devices. They are not subject to national or in- ternational medical device law and must be used accordingly. -
Page 8: Location Of The Freezer Cabinet
Disconnect all poles on the appliance from the power supply before commencing maintenance and repair work (pull the mains plug). The warranty does not cover the free repair of malfunctions resulting from improper installation and handling. Only trained and qualified personnel are permitted to perform service and repair work on refrigeration equipment. -
Page 9: Under Table Installation (Only Applies For Vf 15040 And Vf 15085)
Under table installation (only applies for VF 15040 and VF 15085) The cover panel on the deep-freeze appliance must be removed prior to installation under a tabletop. When the appliance door is open, you can reach the screw connection for the cover by inserting a Phillips screwdriver through the opening on the right side of the upper housing frame. -
Page 10: Operating Voltage And Electrical Connection
Freezer cabinets installed under tabletops must be positioned a minimum of 60 mm away from other appliances or walls so that the aspirated cooling air can circulate freely. Once the freezer cabinet has been moved to its place of installation, it must be secured in position with the locking feet. -
Page 11: Commissioning

Page 21: Optional Water Cooling
Optional Water cooling Installation of a heat exchanger (water cooling agent) instead of the condenser. The heat exchanger reduces the heat emis- sion of the unit to the ambient considerably and extends the permissible operating temperature range. The regulation is pressure-controlled by the Freezer. -
Page 22: Setting The Cooling Water Volume Regulator
7.4.1 Setting the cooling water volume regulator The setting of the cooling water volume regulator is only necessary if the in-house cooling water is significantly warmer or colder than it was set in test mode. The value of the cooling water volume regulator set in test mode can be found on the label on the cover of the cooling water volume regulator. -
Page 23: Alarm Limit Values
Alarm limit values Setting a limit value for the door alarm delay Tap the Menu symbol on the touch screen unit. In the parameter level, scroll down to the USr user level, tap parameter A6, set the required limit value, and save. A timer starts when the door is opened.
