5. Start up
• After connecting the supply lines (chap. 4), turn on the unit by the main power switch (3).
• Open the water-tap for freshwater supply. Alternatively, fill the freshwater can (option, chap. 17.9).
• Turn on the humidifying and dehumidifying system with switch (4) (humidity switch ON/OFF).
After turning on the chamber for the first time, or after an interruption of the power supply, the relative
humidity will increase only after a delay of about 20 minutes. During this period, the relative humidity can
drop considerably.
Warming chambers may release odors in the first few days after commissioning. This is not a quality
defect. To reduce odors quickly we recommend heating up the chamber to its nominal temperature for
one day and in a well-ventilated location.
WARNING: If customer should use a BINDER chamber running in non-supervised continu-
ous operation, we strongly recommend in case of inclusion of irrecoverable specimen or
samples to split such specimen or samples and store them in at least two chambers, if this is
feasible.

Figure 16: MB1 program controller
The MB1 2-channel program controller controls following values inside the constant climate chamber:
Channel 1: Temperature in °C (range without humidity / without light cassettes: 0 °C / 32°F to 70 °C /
158°F)
Channel 2: Relative humidity in % r.H. (range 10 % r.H. to 80 % r.H.)
You can enter the desired set point values in Manual Mode or Program Mode (chap. 5.2) in the display
controller. For the control range of temperature and relative humidity, see chap. 13).
In addition to displaying the actual values of UVA and the visible spectral range, the function “Light Quan-
tum Control” permits cumulative measurement of the light doses. In Manual Mode you can enter target
dose values of UVA and the visible spectral range. When they are reached, the UVA, and cool white fluo-
rescent tubes automatically turn off independently from each other.
