24.5 Disposal of the chamber in non-member states of the EU
NOTICE
Danger of violation against existing law if not disposed of properly.
Alteration of the environment.
For final decommissioning and disposal of the chamber, please contact BINDER ser-
vice.
Follow the statutory regulations for appropriate, environmentally friendly disposal.
The main board of the chamber includes a lithium cell. Please dispose of it according to national regula-
tions.
The refrigerants used 452a and R 23 (only MKFT) are not inflammable at ambient pressure. They must
not escape into the environment. In Europe, recovery of the refrigerants R452a (GWP 2140) and R 23
(GWP 12100) is mandatory according to regulation No. 842/2006/EC. Ensure the compliance with the
applicable legal requirements regarding qualification of staff, disposal, and documentation.
25. Technical description
25.1 Factory calibration and adjustment
The chambers were calibrated and adjusted in the factory. Calibration and adjustment were performed
using standardized test instructions, according to the QM DIN EN ISO 9001 system applied by BINDER
(certified since December 1996 by TÜV CERT). All test equipment used is subject to the administration of
measurement and test equipment that is also constituent part of the BINDER QM DIN EN ISO
9001systems. They are controlled and calibrated to a DKD-Standard at regular intervals.
Repeated calibrations are recommended in periods of 12 months.
25.2 Over current protection
The chambers are equipped with an internal protection not accessible from outside. If these fuses have
responded, please contact an electronic engineer or BINDER service.
25.3 Definition of usable volume
The usable volume illustrated below is calculated as follows:

A, B, C = internal dimensions (W, H, D)
a, b, c = distance to wall
a = 0.1*A
b = 0.1*B
c = 0.1*C

USE
= (A - 2 * a) * (B - 2 * b) * (C - 2 * c)
