It is recommended to clean and refill the pan 2-3 times a week. For emptying and cleaning remove the water pan.
Operate the chamber only with deionized (demineralized) water. Conductivity from 1µS/cm up to a maximum of 20µS/cm.
(Water which is in equilibrium with the CO
due to it´s low pH).
Any corrosive damage that may arise following the use of water of deviating quality or by additives is excluded from
the liability agreement.
If required, you can add microbiologically inhibiting substances such as copper chips, copper sulfate or EDTA
in a concentration of 1 to 5 mmol/l.
Empty the water pan before moving the unit. In case of the contents spilling, immediately dry the chamber carefully and
completely.
Placement of samples
To provide proper air circulation and stable conditions within the chamber, it is necessary to adhere to the following rules:
-
the max height of the samples should not exceed 2/3 of the shelf space,
-
the samples should be placed so that the space between the containers does not exceed 1/3 of the width and height of
the shelf,
-
samples should be placed with equal spacing between each other and the chamber walls.
The picture below is an example of the placement of samples in the chamber.
Following the above rules will provide optimal parameters of temperature variation and fluctuation.
Closing the chamber door
The unit has been equipped with a 2-point lock. To close the door, turn the handle to the vertical position, push the door gently
then turn the handle to the horizontal position. If the door has not been closed properly, an alarm will sound. Closing the door
correctly reduces energy consumption and ensures the specified temperature variation and fluctuation.
