Lifting and transporting the chamber
Inside a building on a smooth floor: Use castors
•Unlock the front castors before moving the freezer
•Angle of inclination less than 5°: Wait 10 minutes before turning on the freezer again
•Angle of inclination: 5° to 10° (maximum!): Wait at least 8 hours before turning on the freezer again
Outside a building: Use technical equipment
•Do NOT lift or transport the chamber using the door, the door handle, the controller housing or the lower housing.
•If possible, avoid transporting the chamber horizontally. It may be transported lying down ONLY on the hinge side
or on its back, but must then stand upright for at least 24 hours before turning on
•Lift the chamber using technical devices (fork lifter) and place it on the transport pallet. Set the fork lifter laterally
or from the rear in the middle of the chamber. Make sure to place all the lateral supports of the chamber on the
forks (check: the fork protrudes at the opposite chamber side).
•Transport chambers ONLY with the original transport pallet. Set the fork lifter only to the pallet. Without the pallet
the chamber is in imminent danger of overturning
•Wear suitable shoes (safety shoes)..
•Transport the chamber only in its original packaging.
•Secure the chamber with transport straps for transport.
Requirements for the location of installation
•Installation inside a building on a non-flammable, flat and even surface, free from vibration
•Do NOT set up chambers in non-ventilated recesses. Ensure sufficient ventilation for dispersal of the heat.
•Permissible ambient temperature range during operation: +18 °C up to +32 °C / 89.6 °F.
•Permissible ambient humidity: 70 % r.h. max., non-condensing
•Installation height: max. 2000 m / 6562 ft. above sea level.
•Do not install or operate the chamber in potentially explosive areas.
•Ensure a distance of at least 100 mm / 3.94 in to the ventilation openings on the freezer’s front and rear.
•Power supply fluctuations must not exceed +/- 10 % of the nominal voltage
Electrical connection data and installation
•The chambers come with an IEC connector plug. Cable length: 2000 mm / 78.7 in. Only use original connection
cables according to the specification given in the Operating Manual.
•Pollution degree (acc. to IEC 61010-1): 2. Over-voltage category (acc. to IEC 61010-1): II. Housing protection
(acc. to 60529): IP 20
•The domestic socket must also provide a protective conductor. Make sure that the connection of the protective
conductor of the domestic installations to the chamber’s protective conductor meets the latest technology. The
protective conductors of the socket and plug must be compatible!
•When connecting, please observe the regulations specified by the local electricity supply company as well as the
local or national electrical regulations. We recommend the use of a residual current circuit breaker.
•Prior to connection and start-up, check the power supply voltage. Compare the values to the specified data located
on the chamber’s type plate.
•To completely separate the chamber from the power supply, you must disconnect the power plug. Install the
chamber in a way that the power plug is easily accessible and can be easily pulled in case of danger.
