3. SAFETY INSTRUCTIONS
In the case of biological incubators, biological safety with regard to the protection of
persons, its surroundings and the load is heavily dependent on the observance of the
applicable regulations by the persons using the equipment.
Even then, however, the possibility of hazards, especially health hazards, arising cannot be
ruled out.
The residual risk depends on the work performed in each individual case.
To avoid errors and causing damage, especially personal injuries, be sure to carefully read
this manual before putting the equipment into operation, and follow all instructions.
Safe and reliable operation of the unit can only be guaranteed if the necessary inspections,
maintenance and repair work are carried out by Heraeus Service Department personnel or
by personnel authorized by our company.
Gas is to be supplied to each unit by means of a pressure reducer with the inlet pressure
set to between 0.8 and max. 1 bar. This setting must not be changed for safety reasons
(FRG: ZH 1/119).
The place of installation must be thoroughly ventilated in order to expel the gases escaping
around the pressure relief valve to the outside.
To maintain the temperature protection function, the functioning of the overtemperature
protection device, temperatur limit controller must be checked at reasonable intervals.
Only original replacement parts authorized by the manufacturer are to be used.
Refer to the Appendix titled "BASIC RULES OF SOUND MICROBIOLOGICAL ENGINEERING PRACTICE".

4. SETUP AND INSTALLATION
When setting up, installing and operating the unit, be sure to comply with all applicable regulations
in your country. (FRG: ZH 1/119, ZH 1/342, ZH 1/343, ZH 1/598)
Transport
Handle the unit with care during transport. Do not lift up the unit by its door.
Refer to TECHNICAL SPECIFICATIONS for weights and dimensions.
Place of installation
The place of installation must be dry and draught-free.
The unit should not be placed or operated in recesses which cannot be ventilated.
To avoid or at least minimize deviations from the technical specifications, the temperature at the place of installation must be in the range +18°C to +30°C.
Set up the unit on a solid, non-flammable surface (laboratory tables, subframes).
Make sure that the unit is in a stable and perfectly upright position.
Do not cover or obstruct the fresh air or exhaust vents in the unit housing
(please observe the minimum clearances - see page 11).
CO2 are admitted into the gassed incubator. CO2 is a health risk hazard. The place of installation must therefore be well-ventilated.
Gases discharged from the pressure relief valve must be safely expelled outside by means of the
ventilation systems.
It may be necessary to take special measures in order to ensure proper ventilation when several
units are installed in the same room.
For information on gas flow during operation, refer to the APPENDIX.

4. SETUP AND INSTALLATION
Gas supply connection
The gas connection are located on the back of the unit.
The gas must be supplied to each unit via a pressure reducer with the inlet pressure set
to between 0.8 and max. 1 bar.
This setting must not be changed for safety reasons
(FRG: ZH 1/119).
The gases must have at least 99.5% purity.
If several units are placed in the same room, special ventilation measures are required.
CO2 gassing
Connect the gas cylinder to the gas nozzle on the unit.
O2 / N2 gassing (optional)
If you intend to run the unit with an oxygen content above 21%, connect an oxygen cylinder.
If you intend to run the unit with an oxygen content less than 21%, connect a nitrogen cylinder.
To deactivate the oxygen control, set the nominal value to 21.0% (average oxygen content
of ambient atmosphere).
RS 232 interface
Serial interface for computer-aided acquisition and documentation of critical operating parameters
(temperature, CO2, relative humidity, error codes, etc.). The RS 232 interface can connect a single
unit in combination with the "Kelvilog" software package, and can be expanded to connect 31
units with the "Netcontrol" hard- and software package.

5. DESCRIPTION OF THE UNIT
Levelling the shelves
The shelves can be aligned with the aid of a spirit level with height-adjustable feet.
Functional principle
The atmosphere in the chamber can be regulated in relation to its temperature, CO2 concentration, O2 concentration (optional) and relative humidity.
Heating system
The temperature inside the unit can be regulated in the range of +7°C to +50°C, but must be at
least +5°C (approx. +7°C for the O2 version) above the ambient temperature of the unit.
Condensation on the glass door is largely prevented by heating the unit door. If the unit door is left
open for a long period of time, however, condensation cannot be ruled out.
The unit door heater can be switched off as required (refer to Chapter headed OPERATION).
This enables the unit to be operated at high ambient temperatures or when the operating temperature is only supposed to exceed the ambient temperature by approx. +4°C.
Example:
Ambient temperature

Heating of unit door
+25°C
+37°C
ON
+24°C
+28°C
OFF
+32°C to +33°C
+37°C
OFF
Gassing
Connection to the gas supplies (CO2,, O2 or rather N2) are located on the rear panel of the incubator.
The CO2 content of the atmosphere in the chamber can be regulated in the range 0% to
20%.
The O2 concentration inside the unit can be regulated in the range 3% to 90% O2 by admitting N2 (< 21% O2) or O2 (> 21% O2).
The sum of the nominal values for CO2 + O2 must not exceed 90%.
Example: 10% CO2 + 80% O2 = 90% (possible)
20% CO2 + 80% O2 = 100% (impossible)
Before entering the chamber, all gases pass through a filter where particles larger than 0.3 µm
are retained. Filter efficiency is 99.998%.
A fan integrated in the rear of the interior wall ensures that the gases and the incubator atmosphere are thoroughly mixed.
The sensors for CO2, O2 (option) and relative humidity are also located on the rear panel of the interior wall. These sensors measure the parameters inside the unit and transmit corresponding signals to the closed-loop controller.
A pressure compensation vent on the rear panel of unit avoids undesirable pressure build-up inside the unit during the admission of gases.
The place of installation must be thoroughly ventilated in order to expel the gases escaping
around pressure compensation vent.
50 079 041
13/45
5. DESCRIPTION OF THE UNIT
Humidification
The atmosphere in the chamber is humidified through the admission of steam generated in a aktiv
humifier. Relative humidity (rH) can be regulated between 60% and 95%.
To ensure reliable operation of the steam generator, only fill the reservoir with fully desalinated or distilled water!
The capacity of the reservoir is approx. 4.7 ltr (difference between min. and max. levels:
2.2 ltr).
Door switch
The heating system, gas supply and humidifier are switched off when the unit door is opened.
The unit door can only be closed when all glass doors are sealed properly. If the unit door is
not properly closed while the unit is in operation, a visual alarm is given (all LEDs flashing).
If the door is open for longer than 10 minutes, an acoustic alarm sounds when this monitoring function is activated by way of function level 1 (refer to Page 26).
Internal fittings
Pull-out shelves, with support brackets to prevent tilting, are arranged inside the units. The support can be offset in the carrier racks at intervals of 46 mm.
Six-piece gas-tight glass screen
By virtue of the small vent cross-section, unnecessary cooling and discharge of the atmosphere in
the chamber is largely avoided when a glass door is opened of the six-piece gas-tight glass
screen.
Lockable outside door
The outside door is lockable.
Disinfection routine
This routine is for disinfecting the interior of the unit. In this process, the unit is heated to 180°C
and kept at the disinfection temperature for approx. 3 hours. The unit is then automatically cooled
down again and the nominal values for temperature, gases and relative humidity are reset. The
entire procedure lasts approx. 13 hours, after which the unit is ready for operation again.
"Potential - free contact" connection
Connection for the customer's own signalling system, e.g. telephone system, building services
management systems.
If the overtemperature-protection device trips or an error is detected by the diagnosis system, a
fault message is sent to the customer's own signalling system.

Level gauge (5)
indicates the water level.
The water level should be in the range between "min and max". This range is equivalent
to a volume of 2.2 ltr. If the water supply falls below the "min." level, a reserve of 0.5 ltr. is
still available.
Filling the water reservoir
For humidification of the incubator, water of the following quality must be used:
demineralised water that has been sterilised.
or
sterile water that has been demineralised. Distilled or autoclaved water is suitable.
Fill the canister with the water and leave the screw cap off. Hang the canister on the bracket located on the upper left of the incubator. (fig 1) Connect the tubing connector (fig 1) into the quick
fit coupling, the water reservoir will be filled under the force of gravity.
Should the water not flow, there may be an airlock in the tube, in which case press on the tube
bulb to move the air through.
Attention:
If the reservoir is overfilled the excess water any will flow from the overflow pipe.
After filling place the filling canister on the floor and allow water in the filling tube to return to the
canister before removing the quick fit connection. (fig 2)
Attention:
After filling completely empty and dry the filling canister, store the canister dry to prevent the
formation of contamination.

6. OPERATE
As the outlet not only functions as an overflow but also as a vent, it must be unsealed while
the unit is in operation.
To drain the empty filling canister, place it on the floor and connect it using the quickrelease coupling (9). Take care that the filling canister does not overflow. Disconnect the
quick-release coupling if necessary.
Always drain the water reservoir before transporting the unit.

Temperature protection device (temperature limit controller)
A temperature protection device is built into the unit and acts as a temperature limit
controller. It conforms to Thermal Safety Class 3.1 to DIN 12880 Part 1/11.78.
In a functional state, the temperature limit controller assumes the control function if the
set temperature is exceeded.
The red indicator lamp (1) "Fault" lights up as soon as the temperature limit controller
responds.
Fig. 6: Temperature
limit controller (6)
The cutout temperature of the temperature limit controller can be adjusted in the range
+20°C to +55°C using a coin or screwdriver.
Have your temperature protection device tested for proper operation at reasonable intervals. This applies in particular before prolonged work processes.
Operational test:
Condition: Nominal temperature (controller) reached/constant.
To run this test, turn the dial on the Temperature Limit Controller so that it shows approx.
+5°C less than the temperature indicated on the temperature controller.
If the Temperature Limit Controller responds and the red indicator lamp (1) "Fault" comes
on, the Temperature Limit Controller is operating properly.
Now set the Temperature Limit Controller to the required value depending on the max. cutout
temperature.
If the Temperature Limit Controller is set to the upper temperature limit, it assumes the
function of unit protection (protection of unit and surroundings).
If the Temperature Limit Controller is set to approx. +2°C above the nominal temperature
set at the temperature controller, it assumes the function of load protection (protection of
unit, its environment and loaded material).
The load protection function is only effective above room temperature.
If "Fault" is displayed during operation:
Check the settings on the Temperature Limit Controller and the controller, and correct them
if necessary. If the fault cannot be rectified, contact our service department.

A malfunction of the unit is not the only explanation for error codes 101, 201. They can also be
displayed after a setpoint is decreased.
Example:
When operating the unit with the setpoint entered for 10% CO2 :
If the CO2 setpoint is decreased to 5% CO2, the unit cannot reach this lower CO2 concentration
quickly enough due to its tightness. Error 201 is displayed.
The designated error messages are displayed when:
Setpoint < actual value.
Setpointtemperatur < ambient temperature + 5°C
To avoid this, open the doors for a short time. This also applies to the reduced temperature.
If these measures are unsuccessful or if errors with undefined codes occur, please notify our

8. OPERATION
Operating control
The microbiological safety of the unit is largely dependent on the proper conduct of the persons
using the unit. Refer to the Appendix "Basic rules of sound microbiological engineering practice".
Be sure to comply with the instructions contained in this manual as well as all applicable regulations and directives in your country (FRG: ZH 1/119, ZH 1/342, ZH 1/343, ZH 1/598).
Before putting the unit into operation
Put on all safety garments necessary to protect hands, face and body; remove jewelry.
Disinfect and clean the chamber and fittings regularly. Only use lint-free materials to wipe
surfaces clean.
Do not use explosive disinfectants. When using alcoholic disinfectants, be sure they comply
with all applicable regulations of your country (FRG: ZH 1/598).
During operation
Correct loading determines the temperature conditions in the chamber. If large objects or
auxiliaries are placed inside the chamber, this can impair the temperature distribution in the
unit.
When loading the unit, do not arrange articles too close to one another on the shelves
(use only approx. 70 % of surface area) in order to avoid impairing air circulation and ensure constant heat flow.
Do not impair temperature distribution. This is mainly caused by the following:
Covering the air vents.
Voluminous objects or apparatus.
Equipment releasing large amounts of heat.
Do not change the settings of the temperature protection devices as this will render load
protection ineffective.
Operating interruptions
If operations are interrupted, make sure that no contamination hazards can occur.
Remove, disinfect and clean any objects or auxiliaries put into the unit.
Disinfect and clean the chamber.
Disinfect and remove any residues.
Disinfect the unit with hot air (disinfection routine).

Oral pipetting is prohibited. Use pipetting aids.
Only use needles and syringes if absolutely necessary.
With all manipulators, be sure to avoid aerosol formation as far as possible.
On completion of work and before leaving the working area, clean hands thoroughly. Disinfect and remoisturize hands if necessary.
Keep working areas clean and tidy. Only equipment and materials actually required should be on the worktops. Keep stocks in the areas or cabinets provided for them only.
Regularly check the identity of the biological agents used if this is a requirement for hazard potential
assessment. The length of the interval between checks should be set according to hazard potential.
With regard to the handling of biological agents, employees must be issued with verbal instructions relating
to the workplace before commencing work. These instructions must be re-issued at least once annually
thereafter.
Employees inexperienced in the fields of microbiology, virology or cellular biology must be given thorough
instructions and be supervised.
Vermin and pests must be combatted regularly if necessary.
Handling of pathogenes
Also heed the following basic rules regarding the handling of pathogenes:
Disinfect all workplaces on a daily basis. It may be necessary to switch disinfectants as a precaution
against resistant germs.
Do not wear protective garments outside the working areas.
Contaminated equipment must be autoclaved or disinfected prior to cleaning.
Waste containing pathogenes must be collected safely and rendered harmless through autoclaving or
disinfection.
If infectious substances are spilt, the contaminated area must be closed off immediately and disinfected.
If work is conducted using human pathogenes against which an effective antidote is available, all
employees who are not yet immune must be vaccinated and checked regularly for immunity in the appropriate manner.
The health of employees must be monitored by medical check-ups, i.e. employees must undergo an initial
check-up before commencing work and subsequent annual check-ups. Medical check-ups should be
conducted in accordance with the applicable employers´ liability insurance association guidelines, in
