1.5 General safety instructions on installing and operating the constant climate
chamber
With regard to operating the constant climate chamber KBF LQC and to the installation location, please
observe the guideline BGI/GUV-I 850-0 on safe working in laboratories (formerly BGR/GUV-R 120 or ZH
1/119 laboratory guidelines issued by the employers’ liability insurance association) (for Germany.
BINDER GmbH is only responsible for the safety features of the unit provided skilled electricians or quali-
fied personnel authorized by BINDER perform all maintenance and repair, and if components relating to
chamber safety are replaced in the event of failure with original spare parts.
To operate the unit, use only original BINDER accessories or accessories from third-party suppliers au-
thorized by BINDER. The user is responsible for any risk caused by using unauthorized accessories.

These values are to be considered as approximate values. The sensor resistance largely depends on
the temperature and humidity conditions during the time of exposition to harmful substances. Avoid
simultaneous condensation. Tolerated error of measurement: ± 2 %r.H. The maximum work place
threshold limit value is the value which can be regarded harmless for humans.
• Vapors of oil and fat are dangerous for the sensor because they may condensate at the sensor and
thus prevent its function (insulating layer). For similar reasons it is also not possible to measure smoke
gases.

2. Unit description
The constant climate chambers KBF LQC are equipped with a multifunctional microprocessor display
controller with 2-channel technology for temperature and humidity and a digital display accurate to one-
tenth of a degree resp. 0.1% r.H. With its comprehensive program control functions, the MB1 display
program controller permits the high precision course of temperature and humidity cycles as well as con-
trolled exposition of the samples up to defined dose values.
With its microprocessor controlled humidifying and dehumidifying system the KBF LQC is a high-
precision climatic chamber. It completely meets the requirements of the stipulated stability and durability
test for pharmaceutical products:
• Stability tests acc. to ICH guideline CPMP/ICH/2736/99 (Q1A)
• Photostability tests acc. to ICH guideline CPMP/ICH/279/95 (Q1B)
Furthermore, it permits simulating exactly and over long periods constant conditions for other applications
such as sample conditioning for material testing of paper, textiles, plastics, building materials, etc.
The APT.line™ preheating chamber system guarantees high level of spatial and time-based temperature
precision, thanks to the direct and distributed air circulation into the interior. The fan supports exact at-
tainment and maintenance of the desired temperature accuracy.
The function Light Quantum Control permits integration of UV intensity and luminous intensity inside the
usable volume. The optical sensors used according to the ICH guideline for stability and durability tests of
pharmaceutical products Q1B. Sensor measurement is to a great extent directionally independent, dif-
fused light is also weighted. The function Light Quantum Control permits apart from displaying the actual
values of UVA and the visible spectral range cumulative measurement of the light doses In Manual Mode
target dose values of UVA and the visible spectral range can be entered. When they are reached, the
UVA and cool white fluorescent tubes are automatically turned off and notifying and alarm messages are
released.
A resistance humidifying system humidifies the air. For this purpose, use deionized (demineralized) wa-
ter. The option BINDER Pure Aqua Service permits using the chamber with any degree of water hard-
ness.
The inner chamber, the pre-heating chamber and the inside of the doors are all made of stainless steel
V2A (German material no. 1.4301, US equivalent AISI 304). The housing is RAL 7035 powder-coated. All
corners and edges are also completely coated.
All unit functions are easy and comfortable to use thanks to their clear arrangement. Major features are
easy cleaning of all unit parts and avoidance of undesired contamination.
The efficient program controller is regularly equipped with a multitude of operating functions, additional
recorder and alarm functions. Programming of test cycles is easily done via the modern MB1 color-
display controller and is also possible directly from the computer via Intranet in connection with the com-
munication software APT-COM™ 3 DataControlSystem (option, chap. 17.1).
The constant climate chamber KBF LQC is regularly equipped with an Ethernet serial interface for com-
puter communication. As a system solution BINDER offers the combination of the constant climate
chamber with ICH compliant illumination and the function Light Quantum Control with the GLP/GMP
compliant software APT-COM™ 3. This comfortable communication software from BINDER permits net-
working up to 30 units and connecting them to a PC for controlling and programming, as well as record-
ing and representing temperature and humidity data. For further options, see chap.21.5.
The KBF LQC is equipped with four castors. Both front castors can be locked by brakes.
The chambers can be operated in a temperature range from 0 °C / 32°F up to 70 °C / 158°F (without light
cassettes) / from 10 °C / 50°F up to 60 °C / 140°F (with illumination) and in a humidity range of 10% r.H.
to 80% r.H. When at least one light sensor is plugged-in, the maximum temperature is automatically lim-
ited to 60 °C.
For the control ranges of temperature and humidity, see diagrams (chap. 13).

Operate the unit with deionized (demineralized) water only.
Types of suitable water quality:
• Deionized water from a water treatment installation already existing at the customer's site. Conductivi-
ty from 1 µS /cm up to a maximum of 20 µS/cm. (Water, which is in equilibrium with the CO
2
in the air,
and has a conductivity below 1 µS/cm (ultrapure water), may cause acid corrosion due to its low pH.)
• Water treated by the optional water treatment system BINDER Pure Aqua Service (disposable sys-
tem). A reusable measuring equipment to assess the water quality is included (chap. 17.10).
BINDER GmbH is NOT responsible for the water quality at the customer.
Any problems and malfunctions that might arise following use of water of deviating quality is
excluded from liability by BINDER GmbH.
The warranty becomes void in the event of use of water of deviating quality.
4.3.1 Automatic fresh water supply via water pipe
An enclosure inside the unit contains the connection kit for freshwater and wastewater. Install the fresh-
water connection using either the enclosed water hose or another pressure-resistant one. For this re-
move the cover of the freshwater connection “IN” (18) on the rear of the unit. Protect both ends of the
hose with two of the four delivered hose clamps.
Before turning on the unit, check the connection for leaks. Water supply then automatically occurs via the
freshwater connection “IN” (18).
As the appliance only lets in water when required, there is no continuous water flow.
• Supply pressure 1 to 10 bar when connecting to a water pipe
• Water type: deionized (demineralized) water
• Water intake temperature NOT below +5 °C / 41°F and not exceeding 40 °C / 104°F.
• The water intake should be provided with a shut-off slide or water-tap.
•
For the water supply, fix the delivered adapter with hose olive on the thread at the rear of
the chamber.
• Protect the water supply at one side with the delivered hose clamp.
KBF LQC (E5.3) 07/2014 page 28/114
4.3.2 Manual fresh water supply via external freshwater can (option)
If no house water connection with suitable water is available, you can manually supply water by filling a
freshwater can (option, volume: 20 liters / 0.71 cu.ft.). You can fix the freshwater can at the rear of the
unit or place it next to the unit (chap. 17.9).
To guarantee humidification during 24 hours even at high humidity set-points with manual
water supply, we recommend filling the freshwater can (option) daily at the end of the day.
4.3.3 Connection kit for connection to the water main
A safety kit against flooding caused by burst water hoses is enclosed to the constant climate chamber. It
consists of:
• Hose burst protection device
• Hose nozzle with screwing
• 4 hose clamps
• 6m water hose, divisible for feed hose and the drain
Protection principle of hose burst protection:
Whenever a strong water flow of about 18 l / min. occurs, e.g. caused by a burst water hose, a valve au-
tomatically cuts off the water supply, what can be heard as a clicking noise. The water supply now re-
mains interrupted until its manual release.
Assembly:
Screw the hose burst protection device onto a water tap with a G¾ inch right turning thread connection.
The connection is self-sealing. Establish the connection between the safety kit and the chamber with a
part of the supplied hose. Protect both ends of the hose by the supplied hose clamps.
We recommend connecting the hose as the last step in order to avoid twisting the hose while screwing on
the safety kit.
Open the water tap slowly in order to avoid actuating the hose burst protection device.
Figure 11: Assembly of the connection kit
Release of the reflux protection device:
In case the burst protection device interrupted the water supply, find first the reason and remove it as far
as necessary. Close the water tap. Release the valve by a half left-turn of the upper knurled part. You can
hear the release of the valve as a clicking noise. Tighten the burst protection device against the water tap
by a right turn. Open the water tap slowly afterwards.
Maintenance of the assembly of the hose burst protection device:
Calcification can impair valve function. We recommend an annual inspection by a skilled plumper. The
plumper should demount the safety kit to check the valve by hand for function and calcification or block-
age.
KBF LQC (E5.3) 07/2014 page 29/114
CAUTION
Danger of calcification.
Impairment of valve function.
Have a plumber inspect the valve annually.
Remove calcifications by citric acid or acetic acid solutions.
Afterwards test the function and the tightness of the mounted unit
Check: Quickly open the water tap while there is no chamber connected – the valve has to cut off the
water flux without any delay.
4.3.4 Safety kit: Hose burst protection device with reflux protection device (available via
BINDER Individual)
For protection of the drinking water system, acc. to DIN 1988 part 4, and against flooding caused by burst
water hoses, a safety kit with reflux protection device is available.
Protection principles:
Whenever a strong water flow of about 18 l / min. occurs, e.g. caused by a burst water hose, a valve au-
tomatically cuts off the water supply, what can be heard as a clicking noise. The water supply now re-
mains interrupted until its manual release.
An eventual endangering of the drinking water system depends on the risk potential of the charging mate-
rial. Under unfavorable conditions (e.g. decreasing pressure inside the tap water system), drained off
charging material could be sucked out of the chamber via the steam generator into the tap water system
and therefore contaminate the drinking water. According to standard DIN 1988, part 4, the safety kit with
reflux protection device provides protection in case of short-term utilization of substances with low risk
potential. When using substances bearing a higher risk potential, install a pipe disconnector in order to
guarantee absolute protection. It is the user’s responsibility to prevent, according to national standards,
any reflux of contaminated water into the drinking water system.
Assembly:
The regularly delivered original parts – hose burst protection device, hose nozzle with screwing – are not
needed.
Screw the pre-mounted assembly of hose burst protection device and reflux protection device onto a
water tap with a G¾ inch right turning thread connection. The connection is self-sealing. Establish the
connection between the safety kit and the chamber with a part of the supplied hose. Protect both ends of
the hose by the supplied hose clamps.
We recommend connecting the hose as the last step in order to avoid twisting it while screwing on the
safety kit.
Open the water tap slowly in order to avoid actuating the hose burst protection device.
Figure 12: Assembly of the safety kit (hose burst protection device with reflux protection device)
KBF LQC (E5.3) 07/2014 page 30/114
Release of the reflux protection device:
In case the burst protection device interrupted the water supply, find first the reason and remove it as far
as necessary. Close the water tap. Release the valve by a half left-turn of the upper knurled part. You can
hear the release of the valve as a clicking noise. Tighten the burst protection device against the water tap
by a right turn. Open the water tap slowly afterwards.
Maintenance of the assembly of hose burst protection device with reflux protection device:
Calcification can impair the function of both valves. We recommend an annual inspection by a skilled
plumper. The plumper should demount the safety kit with reflux protection device to check both valves by
hand for function and calcification or blockage.
CAUTION
Danger of calcification.
Impairment of valve function.
Have a plumber inspect the two valves annually.
Remove calcifications by citric acid or acetic acid solutions.
Afterwards test the function and the tightness of the mounted unit.
Check: Quickly open the water tap while there is no chamber connected – the valve has to cut off the
water flux without any delay.
