1. INTENDED USE AND IMPORTANT INFORMATION FOR THE USER
ST thermostatic cabinets, CHL refrigerators and ILW cooled incubators are laboratory devices designed for incubation
and storage of samples at following temperature ranges:
•thermostatic cabinets ST: +3°C … +40°C / +70°C (option)
•thermostatic cabinets ST BD: +3°C … +40°C,
•laboratory refrigerators CHL: 0°C … +15°C
•laboratory incubators ILW: -10°C (option) / 0°C... +70°C
Thermostatic cabinets and incubators have both heating and cooling systems and forced air convection. Laboratory
refrigerators have only a cooling system. All devices are controlled by a precise SMART controller, thanks to which the
set temperature is maintained with good fluctuation and variation. ST thermostatic cabinets and CHL refrigerators are
also available in multi-chamber versions, in which each chamber is independently controlled - this manual also applies
to devices of this type.
* ST BD thermostatic cabinets are dedicated, among others, for incubation of samples for BOD determination using
OxiTop manometric kits, etc., in which the test bottles are placed on a mixing platform. The platform is connected to the
internal power socket. Depending on the number of BOD sets, the cabinets differ in the size of the chamber and the
number of internal power sockets:
•ST 2 BD: 2 power sockets
•ST 4 BD: 3 power sockets
•ST 5 BD: 4 power sockets
The maximum load on the sockets is 200 W.
The meaning of information symbols
This symbol means that failure to follow the instructions could endanger people's health or life, or
damage the device. The manufacturer is not liable for damages resulting from non-compliance with
the instructions contained in the manual.
A flammable coolant is used in the cooling system. If the cooling system is damaged, ventilate the
room carefully and remove all open flames near the unit.
Warning for devices equipped with UV fluorescent lamps: take special care during work, avoid
exposure of the hands and eyes to ultraviolet radiation. This radiation can cause eye damage
(conjunctivitis) and skin changes (redness, cancer lesions, etc.). It is recommended not to open the device
chamber if UV light is on. The user should be equipped with personal protective equipment (protective
gloves, safety glasses).
This symbol indicates helpful tips.

3.2. Condensation in the chamber
If the set temperature is much lower than the ambient temperature, condensation may occur, which will cause
accumulation of the water at the bottom of the chamber. The amount of accumulated water depends on the following
factors:
•the difference between the ambient temperature and the temperature in the chamber,
•frequency of door openings,
•temperature of the samples.
Too high relative humidity in the chamber can cause icing of the cooling element, and thus reduce the
cooling efficiency and increase power consumption.
Cartons, sponges and other hygroscopic materials should not be used to store samples, as they may increase the
humidity in the chamber.
3.3. Remarks on the placement of samples
To provide proper air circulation and stable conditions in which the samples are stored in the chamber, it is necessary
to keep the following rules:
•the max height of the samples should not exceed 1/3 of the space between the shelves,
•approx. 1/3 of the width and depth of the shelf should remain empty, while the distances between the
samples, as well as between the samples and the wall should be approximately equal.
The picture below is an example of the placement of samples in the chamber.
