Installation

During installation of built-in units, ensure that the
escaping air will be safely discharged out of the
installation space.

Ambient Conditions

Location Requirements

Built-in incubators can, heating and drying ovens must be operated with an air exhaust system
and exhaust hose (only original Thermo accessory should be used).

For safety reasons, the installation space should be made of non-combustible materials,
according to DIN 4102.

The incubator must only be operated in a location that meets all of the ambient condition
requirements listed below:

• Installation location indoors in dry areas free from drafts.

• The dust burden may not exceed the contamination category 2 based on EN 61010-1.
Using the incubator in an atmosphere with electrically conductive dust is prohibited.

• The minimal distance to adjacent surfaces must be observed on all sides (see Section

“Space Requirement” on page 3-3)

• The operating room must be equipped with appropriate ventilation.

• Solid, level, fire-proof surface; no flammable materials opposite to the rear panel of the
incubator.

• Vibration-proof substructure (floor stand, lab table) capable of bearing the dead weight of
the incubator and its accessories (particularly if two devices are stacked).

• The electrical circuitry of the incubator has been designed for an operating height of up to
2000 m above sea level.

• Relative humidity up to 80% (maximum; preferably 60-70%), non condensing.

• Should condensation exist, wait until the moisture has evaporated completely before
connecting the incubator to a power source and powering up.

• The ambient temperature must be within a range of +18 °C to +32 °C (64.4 °F to 89.6 °F).

• Avoid direct exposure to sunlight.

Thermo Scientific Heratherm 3-1

Installation
Intermediate Storage

• Devices that produce excessive amounts of heat must not be placed near the incubator.

• Place the incubator on a floor stand (option; to be ordered separately), never on the lab

• Power line voltage variations must not exceed ±10 % of the nominal voltage.

• Transient surges must lie within the range of levels that normally occur in the power

• Consider installing one dedicated upstream circuit breaker per incubator to avoid multiple

supply system. The impulse withstand voltage based on surge category II of
IEC 60364-4-443 shall be applied at the nominal voltage level.

device failures in case of an electrical fault.

Contamination hazard

Do not place the incubator directly on the lab floor, but mount it
on the floor stand or on a lab work surface (option; to be ordered
separately). Contaminants, such as bacteria, viruses, fungi,
prions, and other biological substances may use the open door to
migrate easily from the floor into the incubator’s work space.

Intermediate Storage

When the incubator is placed in intermediate storage, which is permissible for a maximum of
four weeks, make sure that the ambient temperature is between 20 °C to 60 °C (68 °F to
140 °F) and the maximum relative humidity does not exceed 90%, non-condensing.

Room Ventilation

Heat dissipating from the incubator during continuous operation may cause a change in the
room climate.

• Therefore, the incubator must only be installed in rooms with sufficient ventilation.

• Do not install the incubator in room recesses without ventilation.

• When several devices are to be placed in the same room, additional ventilation may have
to be provided as necessary.

• To avoid any impact of the heat dissipated by the incubator on the ambient climate the
room must be vented by means of a laboratory-grade ventilation system that complies
with applicable local and national health and safety regulations and has sufficient capacity.

• If excessive temperatures tend to occur in the operating room, be sure to provide a thermal
protection means that cuts out the power supply to mitigate the impact of
overtemperature scenarios.

Safety Devices

The incubators are equipped with the following safety features:

• a sample protection feature that safeguards the samples against destruction through
overheating in case of contoller failure;

• an overheat protection cut-out feature that shuts down the incubators IMH-S completely
when excessive temperatures occur in the workspace;

• an alarm relay that is energized, along with audible and visual alarms, to indicate errors
encountered during operation;

• dual fuses rated at 16 amperes.

Work Space Atmosphere

To ensure undisturbed operation, the ambient temperature in the operating room must be at
least 18 °C (64.4 °F).

Product Description

Safety Devices

The heating system uses this temperature threshold to control the ambient temperature plus
5 °C (41 °F) up to the maximum of 105 °C (221 °F).

Door Switch

Heratherm IMH 60/100/180/400/750 S incubators come with a door switch [1] integrated
into the latch mechanism. If the door switch is activated by opening the door, heating
operations in the work space are suspended and an icon is illuminated in the display window
(see D4 in figure 7-1 on page 7-1).

If the door remains open for more than 30 seconds, a short audible alarm is sounded in
addition to the icon in the display window. If the door is left open for more than 10 minutes,
an audible alarm is sounded, a “door open” (E001) alarm message appears in the display and is
issued through the RS-232 interface, and the alarm relay is energized.

Thermo Scientific Heratherm 4-11

Product Description
Sensing and Control System

Sensing and Control System

The PT 100-type sensor for the control of the work space temperature and for the thermal
protection [1] is installed on the bottom of table-top incubators and in the top of floor stand
incubators.

Figure 4-9 Sensor System (for table-top incubators)

Figure 4-10 Sensor System (for floor stand incubators)

The work space temperature sensor provides the inputs to the incubator’s built-in controller,
which continuously compares the measured values to the user-specified set value and adjusts
the heaters according to the result.

Do not remove the protection hose from the sensor.
Protect the sensor from mechanical damage.

The unit features a thermal protection function that is factory-preprogrammed and not
adjustable. It protects the cultures in the work space from overheating: Thermal protection
kicks in on a brief violation of the upper limit, based on the defined setpoint temperature, at
between 2 and 3 °C (35.6 °F and 37.4 °F) (37 °C (99 °F): 2 °C (35.6 °F), > 50 °C (122 °F):
3 °C (37.4 °F)), automatically reducing the work space temperature to the user-specified set
value and allowing the incubation process to be continued even in case of a controller
malfunction. If the thermal protection is activated, the error message (E111) “Temperature
too high” appears in the display window and an audible alarm is sounded.

When the user acknowledges the error message, the red alarm icon (D4 in figure 7-1 on

page 7-1) is illuminated and the Temperature Set Value icon (see table 7-3 on page 7-4) is

highlighted by a red border to indicate that thermal protection has kicked in.

Alarm Contact

The incubator can be connected to an on-site, external alarm system (such as a private branch
telephone exchange, a facility monitoring system, visual or audible alarm indicators). For this
purpose, the devices come with a pre-wired potential-free alarm contact (item 3 in

figure 4-11). The alarm contact is energized whenever an error occurs in an internal control

loop or the incubator’s electrical circuits or hardware.

AC Power Socket

The incubator is connected to the AC supply mains via the socket (item 4 in figure 4-11),
which accepts a power cord with an IEC standard plug.

Fuses

Two 16 A slow-blow fuses mounted on the incubator’s main electronic circuit board protect
internal circuitry from the impact of excessive power consumption.

Thermo Scientific Heratherm 4-13

Product Description
Work Space Components

Replacement should only be carried out by skilled and authorized
qualified personnel of electrotechnology/signal engineering!

Fuse replacement

The device fuses are not user-serviceable. When the incubator exhibits
the typical signs of a blown fuse (no response to pressing the On/Off
button, control panel remains extinguished, no heating operation), call
Thermo Fisher Scientific Customer Service to have the fuses replaced.

Work Space Components

Inner Chamber

All components of the work space are made of corrosion-resistant stainless steel and have an
absolutely smooth and easy-to-clean surface. Any embossings have a large radius.

incubator.

The access port [2] has a diameter of 42 mm.

Shelf System

The incubator is supplied with two perforated shelves. The shelf support rails [1] have an
alternating pattern of oblong and round perforations spaced evenly at 30 mm, allowing the
shelf support brackets [8] to be inserted without any room for error, yet in a very flexible way
to accommodate any required height of sample container. The shelves [2] have an integrated
tilt protection and pull-out stop. For details on using the shelf system, see “Installing the Shelf

System” on page 5-1.

Operating conditions

When accessories are to be operated in the work space of the
incubator, the ambient condition requirements must be observed (see
table below). The energy introduced into the work space has an impact
on the lower end of the temperature control range. When additional
heating sources are introduced into the work space, temperature control
may be adversely affected.

— ?: identifies the command line as a query;

— aaaa: is the parameter address;

— bb:: is a query, that must be left at „00” for technical reasons;

— cc is for a command - specific checksum listed in the table below.

— <CR> is for carriage return.

You will receive a response of the following general format:

!:aaaa:bb:XXXXX:cc<CR>

, where:

— !: identifies the line as a response to a query;

— aaaa: is the parameter address entered with the query;

— bb: is the number of payload bytes in hexadecimal code— for example, 1F for the

decimal value 31;s

— XXXXXX: is the significant status information queried;

— cc: is a check sum (technically an inverted XOR of all bytes returned, excluding the

check sum bytes and the <CR> character);

— <CR> is for carriage return.

Wiring the Alarm Contact

Thermo Scientific warrants the operational safety and the operativeness
of the incubator only if installation and repairs are performed by skilled
personnel.

Installation procedures

Wiring the Alarm Contact

T1 T2 T3 T4

Skilled work

The connection of the incubator to an external alarm system must only
be carried out by adequately trained and authorized electrical
engineering or telecommunications expert personnel!

Functional Description

When system errors and failures occur in the temperature control circuits, an alarm message is
issued to the connected alarm monitoring system. The potential-free contact (single
changeover-type contact) has been designed for the circuit configuration specified below.

The alarm relay is energized by all error conditions reported by internal
control loops.

Installation procedures
Wiring the Alarm Contact

Connection Example

The connector [5] for the interface cable is supplied with the incubator as a standard item.
Specifications for the operating voltage and the fusing of external alarm circuitry are given in
the table above.

1. Wire the individual conductors [1] through [4] of the interface cable as shown in the
wiring diagram.

2. Route the alarm cable along a path that does not cross hot exhaust air piping, tables, aisles
or passageways.
With stacked devices, keep the alarm cable away from hot spots on the other incubator in
the stack.

Alarm contact electrical compatibility
considerations

To avoid overloading and damaging the alarm contact, check the
electrical interfacing parameters of the alarm-receiving system for
compatibility with the alarm relay specifications given above.

3. Plug the alarm system interface cable connector into the interface port [5] in the rear panel
of the incubator.

Figure 5-11 Alarm Contact Connection Example

The circuit diagram shown above represents the undisturbed condition of operation. In case of
an error condition - including a power outage - contact closure occurs on the path between
contacts 1-4.

Operation

Preparing the Incubator

The incubator must not be released for operation before all major start-up activities have been
completed (see “Installation procedures” on page 5-1).

Device Check

Prior to starting operation, the following incubator components must be checked for their
correct function:

• The door seal in the front frame must not be damaged.

• The glass door must not be damaged.

• The shelving components must be installed safely.

• Disinfecting the Incubator’s Work Space

Run the decontamination routine (Heratherm IMH 60/100/180/400/750-S devices only; see
section “Decontamination” on page 7-16) or disinfect the work space according to the
operator-specified hygiene guidelines.

Starting Operation

1. Turn the incubator on using the control panel.

2. Adjust the temperature set value on the control panel.

3. Launch decontamination (optional with Heratherm IMH 60/100/180/400/750-S devices
only; see “Decontamination” on page 7-16).

4. The temperature controller starts adjusting the work space to the user-specified
temperature set value now.

Thermo Scientific Heratherm 6-1

Operation
Starting Operation

5.

To avoid any risk of explosion or fire

• refrain from loading the incubator with any of the substances
listed in the section “Incorrect Use” on page 1-6

• make sure that the ambient air is free of any solvents

• do not operate the incubator in areas with an explosion hazard

6. Load the work space with samples.

Hot surfaces

The screen of the glass door, the interior panel of the outer door as
well as the surfaces of the shelving and the work space become hot
while the incubator is running through its heating cycles and need
some time to cool down.

When removing samples from a running or recently completed heating
cycle, always wear safety gloves and other appropriate personal
protection equipment to avoid burns on hot surfaces!

Risk of overloading

Overloading may damage the shelves or cause the shelves
and/or the incubator to tilt when the shelves are being drawn out,
ultimately destroying the samples. To avoid overloading the
incubator or its shelving be sure to observe the sample weight
limits specified in chapter 13, “Technical Data.”

Proper loading

To ensure sufficient air circulation and uniform heating of the samples,
do not use more than 70% of the maximum surface area of the work
space. Bulky objects in the work space that dissipate heat may impair
heat distribution.

Heratherm IMH Series and IMH-S Series incubators come with a front panel mounted
control unit consisting of a multifunctional display, four control buttons, and an on/off
button. The four control buttons interact with the display window to let users access all of the
user control functions and adjustments of the incubator, including - for example, the
temperature set value, timer, energizing/de-energizing the AC outlet in the work space, as well
as a variety of other functions.

Under normal operating conditions the display presents user with the work space temperature.
The display returns to its default mode upon completion of the adjustments or whenever no
entries have been made for a period of 30 seconds.

Power Outage during a Decontamination Run

A power outage relaunches the decontamination
routine automatically. The Alarm icon (leftmost item of
the group “D4” on page 7-1) is illuminated in the display
window, and a E007 Power Down Error message

appears at the end of the process. Press the
button to acknowledge that alarm.

Put up bio-hazard warning signs!

Under specific circumstances, there is a risk that bacteria,
viruses, fungi, prions, and other biological substances
survive when the decontamination routine is aborted due to
a power outage. Normally, the incubator starts over with the
decontamination cycle without any need for user
intervention upon return of power. Users who fail to notice
the power outage, may open the door and/or load the
incubator with samples, thus exposing themselves or their
samples to bio-hazards without being aware of that risk.

Shutting the Incubator Down

This chapter provides instructions for shutting the incubator down for prolonged periods of
time, that is, at least for several days in a row.

If the work space surfaces are contaminated, harmful biological
material may spread to the environment of the incubator.

To rule out any risk for subsequent users, perform a full cleaning,
disinfection and decontamination cycle to the standards set out
in the section “Cleaning and Disinfection” on page 9-1 if you
suspect (or if you are positive) that harmful biological material
has been processed with the incubator.

1. Remove the containers with the cultures, all accessories, and other objects from the work
space.

Contamination hazard

2. Clean and disinfect the work space, as explained in the section “Cleaning and
Disinfection” on page 9-1 or - if the above warning note applies - run the dry
decontamination routine at 140 °C / 284 °F (see “Decontamination” on page 7-16).

3. When cleaning and disinfection and/or decontamination are done, turn the incubator off
using the control panel.

4. Unplug the power cord and secure it against accidental reconnection.

5. Until the incubator is shut down, the work space must be continuously ventilated. Leave
the glass door and the outer door open and secure them against accidental closure.
