general
The electrically heated ovens/incubators
are designed for laboratories, especially for
tempering of various materials by hot air at
adjustable temperature and optional time mode.
An air ap enables to dry wet materials.
An advanced modern microprocessor (Fuzzy
- logic) with a digital display and a PT 100
controls the temperature course. This system
provides high accuracy of temperature control
and reliability of the tempering process. The
second independent digital safety system
ensures, together with the second independent
temperature sensor, the control and safety of the
tempering process for the whole device life.
These devices meet all legislative requirements
and are designed according to respective EN
standards – see Conformity Declaration. They
are made of high-grade materials by using the
latest technology.
Each unit undergoes a careful output control.
1.1
PURPOSE AND USE
ECOCELL (EC) is intended for tempering of
materials by hot air with natural circulation. The
units are designed for temperatures up to
250 °C, optionally up to 300 °C. Compared
with VC units they are characterized by quiet
operation and lower consumption of electrical
energy.
DUROCELL (DC) serves for hot-air tempering
with natural circulation (use for the following
procedures: Acid hydrolysis, extraction of non-
ammable substances, thermal decomposition
in closed vessels). The devices are intended for
temperatures up to 125 °C. The inner surfaces of
the chamber are covered with an EPOLON layer
which protects the chamber against corrosive
action of acids in form of liquids or vapours in case
of their accidental leakage from closed vessels.
For other important information see the chapter
Before Putting into Operation.
VENTICELL (VC) is intended for tempering of
materials by hot air with forced air circulation
by means of a fan. The ovens are designed for
temperatures up to 250 °C, optionally up to 300 °C.
INCUCELL (IC, ICV) serves as an incubator or
for cell cultivation in microbiological laboratories
(see chapter Optional equipment; Anti-dry
modication of cultivating mediums and tissue
cultures). The units are designed for temperatures
up to 70 °C optionally up to 100 °C. A quiet
operation is characteristic for the version IC
(without a fan), more accurate temperature
regulation with small deviations is characteristic
for the version ICV (with ventilator).

important
instructions
2.1
UNPACKING, CHECKING AND
TRANSPORT
Please check after unpacking whether the
unit and its accessories are complete and not
damaged. An eventual damage has to be reported
to the transporting company immediately. During
the manipulation – in case of lifting the cabinet
etc. – the unit must not be held by the rail or
door. The units of volumes 404 and 707 shall be
lifted by means of supplied hooks; the casters
are designed for local moving only, not for longer
transport. A standard delivery consists of a
temperature cabinet and two sieves, three chip
cards formatted for program download (marked
Programs – empty) and one special operations
card (SO).
Attention: If an SO card is used for a program
download, its original function will be cancelled.
2.2
bEFORE INSTALLATION
● Please read carefully the Operating
Instructions before starting the work
with the unit!
● Install the instrument by plugging the power
cord to a line voltage socket. The specied
parameters of the connection are described
in chapter 5.1 - Electrical Connection.
● At temperatures of above 100 °C the inner
chamber surface becomes yellowish. This
coloration is neither the material nor the
device defect.
After the rst starting of the unit the heating
elements and insulation start to be baked
with a typical smell; after a few operation
cycles this smell disappears, nevertheless,
it is suitable, during the insulation baking at
a temperature above 100 °C, to provide a
sufcient air exchange (e.g. by ventilation
or exhaustion).
Instructions for use
LSI-S_np_en_1309_mmm_V2.10_B2V 3

With VC and EC types the air exhaust is
protected by a cover at the rear wall of the
unit. This cover is placed inside the unit
while shipping. When installing the unit,
insert the cover into the horizontal openings
bellow and above the exhaust to attach it
behind the exhaust.
DC-type – regarding the fact that it is the
inner chamber only which is resistant to
corrosive effects, the following must be
ensured during the application:
a) Processes specied in the previous
chapter must be performed in the chamber
in closed vessels (corrosive substances
release into the chamber must be prevented);
b) Exhalations from the exhaust outlet must
be exhausted actively to prevent vapour
condensation on the outlet and its dripping
down to the electric part of the device;
c) The whole device must be placed in a
no-corrosive atmosphere (damage of the
source and regulation electronics must be
prevented).
The units are designed for indoor operation
within the ambient temperatures ranges
from 5 °C to 40 °C and at maximum relative
humidity 80 %.
The oven shall be installed in a distance of
min. 100 mm from the rear and sidewalls.
The temperature of the outlet air on the
exhaust may be up to 250 °C (or 300 °C);
this area is labeled by .The walls near
the oven shall be incombustible.
The load-bearing capacity of the oor
during installation of the device shall
correspond to the weight of the unit itself
taking the weight of the maximum charge
into consideration (see chapter
5 - Parameters of the Unit).
The unit must not be placed on a support
that could cause a danger of re or
smothering in case of falling some hot
object out of the unit.
Noinammable,explosiveortoxic
materialsmaybeputintooven!The
same applies to materials that could
release such substances.
Material is only to be put on trays, never
directly on the bottom of the unit!
No articles may be put on he external
surface of the unit.
The unit is not intended for warming up the
liquids.
The units are not intended for use in the
atmosphere with a possible danger of
ammable or explosive anesthetics.
Any assembly or disassembly may be
done only when disconnected from the
mains! After switching the unit off with
thekey(key11,g.4)theunitcomes
onlytoastand-bymode,however,itis
not disconnected from the mains!
● If the unit is not used for a longer time,
disconnect it from mains by pulling the
power cord out of the socket.
The units are supplied with the maximum
permitted temperature set to the maximum.
The power cord must not come in contact
with hot parts of the units – with the
exhaust hole cover.
● Protection of the temperature box, its
surroundings and processed material
against inadmissible temperature excess is
secured by a safety system.
Pull out and subsequently push in the
upper metal plate piece of internal chamber
carefully, there is a danger of cutting
through the rubber gasket of the chamber
through careless manipulation.
The maximum permitted loads: see chapter
5 - Parameters of the Unit.
When operating the cabinets at high
chamber temperatures there can be the
maximum allowed temperature of 70 °C at
their external surface (exhaust ports and
their surroundings and the surroundings
of the chamber sealing, window and door
surface in case of the optional type with
window in door) surpassed and there is a
danger of burns. Please be very careful.
● During the operation of the devices of
404 and 707 at high temperatures a
deformation of the inner door surface
occurs as a consequence of thermal
tension, which makes their closing more
Instructions for use

difcult. If you open the door in this state,
do not close them until the chamber
is cooled down. Otherwise the door
mechanism could be damaged.
Regularly – in daily intervals – check by
listening if after the start the fan of the case
is running.
2.3
USEFUL SPACE
The useful space is illustrated on Fig. No.1,
where X(D) = 10 % of the inner chamber depth,
X(W) = 10 % of the inner chamber width, X(H)1
is the distance from the lowest tray to the bottom
of the inner chamber, X(H)2is the distance from
the upper most tray to the ceiling of the inner
chamber. The required temperature accuracy
- see chapter 5 - Parameters of the Unit - is
achieved only within the space dened above
(in connection with DIN 12 880 - marked with
thick lines, thinner lines mark the inner chamber
walls). (It means, that over the last upper tray the
limits from chapter 5 - Parameters of the unit –
are not obligatory).

After the setting is changed, the printer must be
switched off and on either by the switch or by
disconnection from the power supply.
(A different type of the printer must be adjusted
with the help of the printer´s manual and the data
on the interface RS232 shown on the case.)
Connect the printer to the device by means of a
cable with serial connector (RS-232C). Connect
one end of the cable to the printer socket (see
Fig. 4) and the other one to the connector in the
rear part of the printer. Connect the printer to the
electric power mains by means of an adapter.
Some types require the switch on the right side
of the printer to be switched on. The indicators
POWER and SEL light up. The printer is in the
on-line mode. Paper is fed by pressing the LF
button (in the on-line mode only, i.e. after the SEL
button pressing – the SEL indicator turns off. To
renew the on-line mode, the SEL button must
be pressed – the SEL indicator lights up). The
printer can print in the on-line mode only!
Follow the chapter User Support Functions to set
the type of data from the COM output connector
(user mode U3) and the required print interval
(user mode U1).
By the printer interval setting you can determine
the time intervals of actual chamber temperature
printing. The interval is shown in the record
heading.
The printer interval can be set on the display
in the range from tmin = 1 min to tmax = 255 min
(i.e. 4 hours 15 min) in 1-minute increments.
4.5.2
PRINTING
1. The printer prints out the heading showing the
device type, programme number, number of
cycles, pre-set temperature, time of the start
delay, and the required time interval.
2. Then the printer prints out the procedural
data and titles of the procedural data columns
(physical unit inclusive).
3. Below that, the values of the following
procedural data are printed out:
- Actual temperature in the chamber;
- Time from the programme start.
4. Other printed data:
- Start of individual phases;
- Change of any required value;
- Change of a user function inuencing the
cycle procedure (U1, U3, U4, U6, U8) m,
including the new value printing;
- Alarms activation/deactivation, including the
description;
- For IC,ICV: Activation or deactivation of
the safety system warning, including the
description;
- Error state activation, including the
description.
5. In case of power failure and subsequent
power recovery, the printer prints out “-->
Power recovery!” Counting of the printing time
intervals starts from the moment of power
recovery. A new heading is printed out after
switching the device off and on by means of
ON/OFF.
If there is a power failure of the printer only, or
if the printer is switched off, the printer shows
no message after the power recovery or the
printer switch-on.
4.6
SAFETY SYSTEM FUNCTION AND
SETTING
The safety system watches the exposure process
controlled by the control circuit. It also performs
the function of a safety thermostat and serves to
protect the temperature box, its surroundings and
the processed material against an inadmissible
excess of the set temperature (it will e.g. prevent
the damaging or destruction of material samples
in case of the temperature regulator damage, or
unintended setting of a higher temperature than
that tolerated by the sample in the unit chamber).
Supervision is performed both under the normal
operation and in a Stand By.
The safety system measures the temperature
independently at the same place like the
regulatory sensor and counts the time

Instructions for use
LSI-S_np_en_1309_mmm_V2.10_B2V 11
independently. If the set maximum temperature
and period of time are exceeded, the safety
relay switches off the heating, indicates the error
state by its indicator ashing (red) and passes
the information about the error to the controlling
unit which then passes to the error regimen and
indicates the error.
To cancel the error by the user, hold X/W. The
controlling unit cancels the error state in the
safety system circuit. The device passes to a
break state in which parameters can be reset, or
you can let the chamber cool. The device is put
into operation by pressing ON/OFF.
4.6.1
CHANGE OF MAxIMUM AND
MINIMUM VALUES
It is performed in the user settings U6, U8 – see
the safety system function diagram and
description of the user settings. Minimum
difference from the set regulated temperature
should be ± 5 °C.
4.6.2
SUPERVISORY CIRCUIT DIAGRAM
FUNCTION
T limiting – threshold temperature is the
maximum operation temperature permitted by the
manufacturer in all phases and watched by the
safety system. Its value depends on the device
type and cannot be changed.
T User High – safety user upper temperature
limit is the maximum temperature permitted by
the manufacturer for the phase of temperature
rise, exposure and cooling, pre-set in U6 and
watched by the safety system.
T delay – maximum allowable temperature of
the delayed switching phase. It is set itself at
the cycle beginning to the sum of the actual
temperature plus 30 °C.
Tnal- maximum permitted temperature after
termination of cooling. It reaches the T exp max
temperature or 55 °C, whichever is lower.
D delay - time of the delayed switching may vary
from the set time for ± 2 min.
D rise - max. rise time according (Safety Time) to
the setting in the user mode U8.
D exposition - exposition time may vary from the
set time for +3 min / - 0 min.
D cooling - max. cooling time is set to 24 hours.

CHECKING THE SAFETY RELAY
FUNCTION
The test is performed automatically in the
phase of the temperature rise, without the cycle
inuencing, and after the period between tests
elapsing (3,000 hours). The said time is counted
in the exposure phase. After the device is
connected to the power mains, the safety relay
state is monitored as well. If the test result is not
good, Err 24 is announced.
4.6.5
CHECKING THE CORRECT ACTIVITY
OF THE SAFETY SYSTEM
Checking is performed after the required
temperature reached the steady state
(10 minutes at least) in the exposure phase. If
you change the user safety temperature in U6,
do not forget to record each temperature change
in the safety system by ON/OFF pressing before
leaving the user mode.
Temperature exceeding:
•Activate the user service, mode U6.
•Set the user safety upper temperature to a
value exceeding the required one by 5 °C. The
protective circuit must not react.
•Set the user safety upper temperature to
a value 5 °C below the required one. The
protective circuit must react. The safety
system indicator lights up and error Er13 is
announced. In INCUCELL, the safety system
indicator lights up only.

ADjUSTING AND FUNCTION
OF THE AIR FLAP
Function description:
The air ap is intended for ventilating the
chamber space of the unit, for example when
drying wet materials.
Airapadjustment:
Adjust the air ap when installing the unit. Put the
control lever of the air ap to the closed position
and adjust the air ap in the exhaust hole at the
rear wall of the unit so that it closes the entire
ventilating hole. Hold the shaft of the ap with
pliers to prevent turning over.
Note:
With VENTICELL and INCUCELL WITH FAN it
is necessary, in addition to the exhaust ap, to
adjust the sucking air ap as well.
Theairapcontrol:
If you put wet materials into the unit to dry it
before tempering, put the air ap in the position
open so that the humidity could freely leave the
chamber. After nishing the drying put the air ap
in the position closed.
Note:
Operating the unit with an open air-ap increases
the power consumption and the maximum
temperatures may not be reached.

for disconnection. Such a switch or circuit breaker
must be:
– A component part of the building installation;
– Placed in an immediate vicinity of the unit and
accessible easily by the operator;
– Labelled as the device disconnecting element;
– Rated correctly and must comply with the
requirements of the standards IEC 60947-1 and
IEC 60947-3.

cleaning and
decontamination
of the unit
Clean the unit while cold and when the power
supply cord is disconnected from the mains.
Clean the interior walls of the chamber as well as
the exterior of the unit with water and detergent,
or possibly with suitable chemicals. Abrasive
cleaning agents may scratch the metal sheets.
If you want to clean the outer jacket of the
chamber, take the inner walls of the chamber out
as follows:
Shift the upper wall of the chamber out of the
unit, take out the sidewalls, the bottom and
the rear wall. Put the unit together in a reverse
Instructions for use
LSI-S_np_en_1309_mmm_V2.10_B2V 17

Instructions for use
sequence after it has been cleaned, be careful
and slide in the bottom and the sidewalls as far
as behind the four projections in the front part of
the chamber.
In case some contaminated material has
escaped into the chamber the user is responsible
for proper decontamination of all contaminated
surfaces with suitable and approved disinfecting
agent.
Casesofvolume22–EC,DC,IC:
Unbolt the screws in the back part of the ceiling
and of the bottom of the chamber. By pulling out
the walls in the direction to the door you release
the walls and remove them from the apparatus.
When you perform the assembly, you insert
the front bend of the bottom under the holder
of the heating radiator and lock the bottom with
a screw. When you perform the assembly of
the ceiling you put the back part on the sensor
holder, put the front bend of the ceiling on the
ceiling holder and lock with a screw.
(When you perform the assembly/disassembly
of VC, ICV, use the identical procedure, after
releasing the screw of the bottom, you tilt out the
back wall.)
Before using some other cleaning or
decontamination method different from our
recommendation, it is suitable for the user to
be informed by with the producer whether the
intended method cannot cause damage to the
device.

maintenance
No special maintenance is necessary. In case of
any troubles, please, call the service.
Inspection of electric components:
The cases of thermal technique are destined for
a basic/normal environment, the manufacturer
recommends the inspection period of 1 year, if
not determined by local regulations otherwise.
Inspection operations:
Inspection of the electrical installation, particularly
of the electric power supply, of connecting
terminals and a protective terminal.
Check the integrity of the conductor insulation
(for example, due to wearing through, burning
etc.) and the rm connection in the terminals.
The resistance of the protective connection is
< 0.1 Ohm, the resistance of the supply is not
included.
18 LSI-S_np_en_1309_mmm_V2.10_B2V
If the case is placed in a different environment,
the inspection must be performed in accordance
with the local standards.
The service inspection is the matter of agreement
between the client and the service organization.
