2.10 Preparations for operation
2.10.1 Unscrewing/activating the leveling feet (if any)
The leveling feet are not unscrewed/activated before switching on the temperature control unit
DEATH OR SERIOUS INJURY DUE TO CRUSHING
 The parking brakes must be activated at the casters (if any) and/or the leveling feet must be
unscrewed/activated before the temperature control unit is put into operation.
 The temperature control unit may move if the parking brakes of the casters (if any) are not
activated and/or the leveling feet are not unscrewed/activated.
Always unscrew/activate the leveling feet before switching on the temperature control unit.
Uneven floors can be compensated by adjusting these leveling feet.
PROCEDURE
 Verify that the parking brakes of the casters (if any) have been activated.
 Unscrew the leveling feet.
 Compensate uneven floors by adjusting these leveling feet, if necessary. Use a spirit level to
horizontally align the temperature control unit.
 Tighten the lock screws on the leveling feet after aligning the temperature control unit. This
prevents the leveling feet from changing their height during operation.
