LAUDA-GFL Versafreeze Freezer Cabinets for the long-term storage of organic substances, for example, operate silently
and with exceptional reliability. Insulation consisting of vacuum insulation panels and polyurethane foam is the key to its eco-
nomical energy consumption.
The refrigeration compartment is made entirely of stainless steel.
The refrigeration system incorporates fully hermetic, air-cooled high-performance compressors and is maintenance-free.
Freezer cabinet models VF 15040, VF 60040, VF 70040 can be set to temperatures as low as -40 °C.
Freezer cabinet models VF 15085, VF 60085, VF 70085 can be set to a temperature between -50 °C and -85 °C, and
offer the best temperature stability in relation to the set temperature.
Before installing the appliance, please check the content of the delivery for completeness and integrity.
If you discover damage or have any complaints, please get in touch with your supplier or contact us directly.

1Using the freezer cabinets
Intended use
LAUDA Versafreeze Freezer Cabinets can be set to temperatures between 0 °C and –85 °C, depending on the version.
The Freezer Cabinets are intended for the long-term storage of organic substances, for example.
In order to guarantee that the freezer cabinet functions perfectly, always read and observe the information
in these operating instructions. Only persons familiar with these operating instructions are permitted to
install and operate the appliances.
Caution:
Due to the low temperatures in the refrigeration compartment, suitable protective gloves must always
be worn when storing and retrieving refrigerated goods. Arms must also be covered.
Improper use
LAUDA Versafreeze Freezer Cabinets are not suitable for the long-term storage of food and beverages, or similar prod-
ucts. The storage of highly flammable and/or explosive substances is forbidden.
The freezer cabinet must not be installed or operated in laboratory areas with aggressive or corrosive ambient conditions.
Aggressive media such as hydrochloric acid may not be heated or evaporated in the immediate vicinity or inside the appli-
ance itself. 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.
2Warranty
All laboratory equipment and accessories from LAUDA-GFL Gesellschaft für Labortechnik mbH are subject to warranty
claims, including repairs, installation and spare parts. In order to identify faulty appliances, we need the type designation
and the serial number from the type plate located at the top left of the right side wall of the freezer cabinet and possibly a
copy of the invoice.
3Before starting up
In order to guarantee that the freezer functions perfectly, always read and observe the information in these operating in-
structions. Safety instructions are identified by the following warning symbols.
Read and observe the

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. In the event of repair work, the refrigerant quantity must not exceed the initial fill quantity.
See the type plate for quantity information and material specifications.
Before soldering work is carried out on the refrigeration system, the refrigerant must be drained com-
pletely and the system blown through with dry nitrogen. Only trained and qualified personnel are permit-
ted to dispose of refrigerant and removed components.
Caution: flammable refrigerant (hydrocarbons)
Due to the nature and quantity of the refrigerants used, naked flames are prohibited within a radius of 1 m
of the appliance.
Removed components bearing this marking must be disposed of separately.
4Location of the freezer cabinet
Always install the appliance on a solid, flat, horizontal indoor surface. The installation room must be at least 24 m³ in size.
Alternatively, the installation room must be ventilated. Freezer appliances must be positioned a minimum of 150 mm
away from other appliances or walls so that the aspirated cooling air can circulate freely. The condenser on the back of the
appliance must not be obstructed or blocked in.
The ambient temperature must not exceed +28 °C, as this would reduce the cooling capacity of the appliance and in-
crease the temperature in the refrigeration compartment. Effective ventilation in the installation room is usually sufficient
to lower the temperature.
The appliance is not intended for use in areas with an explosion hazard, such as during anesthesia using flammable gases or
vapors. Please refer to the technical data for information on the appliance protection level.

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. After loosening the screw, pull the cover panel approx. 2 cm forward and then
lift from the appliance.
Please refer to the illustration below for the minimum dimensions for under table installation.
Before the appliance is moved to its place of installation, the electrical system (see point 5 of these instructions) and, if
necessary, the alarm system (see point 8.5) must be connected. Ensure that the connection cable is not damaged when
the freezer appliance is moved.

10 / 44 Versafreeze Freezer Cabinets 07/2021
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. The locking feet are positioned at a distance of approx. 40 mm from
the side walls under the front of the appliance. Use the wrench supplied to unscrew the feet by turning clockwise until they
are resting securely on the ground. It should now no longer be possible to move the appliance on the casters.
Caution!
Due to the nature and quantity of the refrigerants used, naked flames are prohibited within a radius of 1 m
of the appliance.
5Operating voltage and electrical connection
A marked equipotential bonding connection is located on the back of the freezer cabinet. Local regulations may stipulate
the need to connect the appliance to a grounding network for equipotential bonding. Please check before commissioning
the appliance.
The operating voltage and the mains frequency on the type plate (right side wall, top left) must
match the power supply specifications.
The main switch on the refrigeration system must switched off (position 0). Once these conditions
have been met, establish the electrical connection.
The refrigeration system may only be operated on a correctly installed power connection with a protective
earth conductor (PE) that complies with local regulations.
It must be possible to disconnect all poles of the power supply from the power network (e.g. via an earthed
socket or switch).
