Message Display: Shows system status (Mode) at all times. Shows ‘CLASS
100’ or ‘SYSTEM OK’ during normal operation, or alarm messages if
the system detects an alarm condition (see Section 4, Alarms). The message ‘CLASS 100’ is a timing mechanism indicating that, under normal
operating conditions with the HEPA filter installed, the air inside the
chamber meets the Class 100 air cleanliness standard for particulates of
0.5 micron size or larger per cubic foot of air. Further information on
the Class 100 classification of air quality is available from Thermo.
Upper and Lower Displays: The 7 segment upper display shows temp and
RH. The lower display shows CO2 and O2.
1. Maintain a minimum six inch clearance behind the unit for electrical
and gas hook-up. In addition, a minimum three inch ventilation
clearance is needed on each side.
2. Locate the unit on a firm level surface capable of supporting the unit
weight of 260 lbs (118kg) plus the estimated total sample and user
equipment weight.
3. Locate the incubator away from exterior doors and windows as changes
in outdoor temperatures and contact with direct sunlight can affect the
anti-condensation functions of the unit.
4. Position the door opening away from forced air heating and cooling
ducts as these can carry dust, dirt, and other contaminants into the
incubator chamber, as well as negatively affect the door opening
recovery time.
5. Lift the unit by the sides of the cabinet base. Do not attempt to lift it
by the front and back. This places stress on the outer door hinges.

Filling the Humidity
Pan
Fill the humidity pan with sterile distilled water to within ½” of the top
with 0.8 gallons (3 liters) of water. If the water cannot be sterilized, a 2%
solution of quaternary ammonium can be used as a disinfectant additive to
control bacteria and other organic contaminants, if desired. Place the pan
directly in the center of the incubator floor to ensure optimum humidity
and temperature response.
For optimum incubator operation, the recommended water type is sterile
distilled Type 2 water with a pH between 7 and 9, and a resistivity
between 50kΩ - 1MΩ-cm (conductivity of 1-20μS/cm). Reverse osmosis
(RO), deionized (DI), and ultrapure Type 1 water can corrode stainless
steel, copper, glass, and other incubator components over time because
high purity water with low ionic content and high resistivity will actively
pull ions from these materials. If sterile distilled Type 2 water is not
readily available, then these other water types could be used by adding the
necessary amount of a sterile solution of weak sodium bicarbonate to raise
the pH between 7 and 9 and lower the resistivity between 50kΩ - 1MΩcm (conductivity of 1-20μS/cm).
Distillation systems, as well as some types of reverse osmosis water purity
systems, can produce water in the quality range specified. Tap water is not
recommended as it may contain chlorine, which can deteriorate the
stainless steel. Tap water may also have a high mineral content, which
would produce a build-up of scale in the pan. High purity or ultra pure
water is not recommended as it is an extremely aggressive solvent and will
deteriorate the stainless steel.

Filling the Humidity
Pan (continued)
High purity water has a resistance of above 1M to 18M Ohm. Even high
purity water can contain bacteria and organic contaminants. Water should
always be sterilized or treated with a decontaminant, safe for use with
stainless steel as well as safe for the product, prior to being introduced into
the humidity pan.
Check the level and change the water frequently to avoid contamination.
Do not allow the water level to fluctuate significantly. “Dry-outs” will
have an adverse effect on the humidity level and CO2 calibration of the
T/C units.
Caution Distilled or de-ionized water used in the humidity pan must be
within a water quality resistance range of 50K to 1M Ohm/cm to protect
and prolong the life of the stainless steel. Use of water outside the specified
range will decrease the operating life of the unit and may void warranty. s
Connecting the CO2
Gas Supply
Warning High concentrations of CO2 gas can cause asphyxiation! OSHA
Standards specify that employee exposure to carbon dioxide in any eighthour shift of a 40-hour work week shall not exceed the eight-hour time
weighted average of 5000 PPM (0.5% CO2). The short term exposure
limit for 15 minutes or less is 30,000 ppm (3% CO2). Carbon dioxide
monitors are recommended for confined areas where concentrations of
carbon dioxide gas can accumulate. s
Warning This incubator is designed to be operated with CO2 gas only.
Connecting a flammable or toxic gas can result in a hazardous condition.
Gases other than CO2 should not be connected to this equipment. CO2
gas cylinders have a UN1013 label on the cylinder and are equipped with
a CGA 320 outlet valve. Check the gas cylinder for the proper
identification labels. The CO2 gas supply being connected to the incubator
should be industrial grade, 99.5% pure. Do not use CO2 gas cylinders
equipped with siphon tubes. A siphon tube is used to extract liquid CO2
from the cylinder which can damage the pressure regulator. Consult with
your gas supplier to ensure that the CO2 cylinder does not contain a
siphon tube. Gas cylinders should also be secured to a wall or other
stationary object to prevent them from tipping.
A two-stage CO2 pressure regulator is required to be installed on the outlet
valve of the gas cylinder. Input pressure to the incubator must be
maintained at 15 psig (103.4 kPa) for proper performance of the CO2
control system. A single stage CO2 pressure regulator will not maintain 15
psig (103.4 kPa) to the incubator as the pressure in the CO2 cylinder
decreases; therefore, a two stage regulator is recommended.

Section 1
Installation and Start-Up
Connecting CO2 Gas
Supply (continued)
Warning If higher purity CO2 is desired inside the incubator (greater than
99.5% pure), the pressure regulator should be constructed with a stainless
steel diaphragm, along with specifying the purity of the CO2 from the gas
supplier. Follow the manufacturer’s instructions to ensure proper and safe
installation of the pressure regulator on the gas cylinder.
Consult your facility safety officer to ensure that the equipment is installed
in accordance with the codes and regulations that are applicable in your
area. s
The CO2 gas supply being connected should be industrial grade 99.5%
pure and should not contain siphon tubes. Install a two-stage pressure
regulator at the cylinder outlet. The high pressure gauge at the tank should
have 0-2000 psig range. The low pressure gauge, at the incubator inlet,
should have a 0-30 psig range. Input pressure to the incubator must be
maintained at 15 psig (103.4 kPa).
The incubator has serrated fittings on the back of the cabinet to connect
the gas supply. Refer to Figure 1-19. The fitting is labeled CO2 Inlet #1
Tank. Make sure that the connections are secured with clamps. Check all
fittings for leaks.

Setting the Overtemp
Setpoint
Caution The independent overtemp system is designed as a safety to
protect the incubator only. It is not intended to protect or limit the
maximum temperature of the cell cultures or customer’s equipment inside
the incubator if an overtemp condition occurs. s
Series 8000DH incubators are equipped with a secondary temperature
monitoring system to monitor the air temperature inside the cabinet. This
system is designed as a safety device to turn off all heaters in the event of a
temperature control failure. Temperature control in the incubator will be
±1° of the overtemp setpoint.
The overtemperature is set by the factory (default) at 40°C. However, the
overtemp can be set up to 55°C in 0.5° increments.
If the incubator’s operating temperature setpoint is set above the overtemp
setpoint, the overtemp setpoint will automatically update to 1°C above the
temperature setpoint. It is recommended that the overtemp setpoint be
maintained at 1°C over the operating temperature setpoint.

All T/C CO2 cells are calibrated at the factory at 37°C, high humidity,
and 10% CO2. Therefore, if a temperature setpoint of 37°C has been
entered, the humidity pan has been filled and the CO2 control is to run
between 0-10% with a T/C CO2 sensor, the CO2 setpoint may be entered
immediately. Otherwise, it is important to allow the unit 12 hours to
stabilize at the temperature setpoint before entering the CO2 setpoint.
Both models of the incubator have a CO2 setpoint range of 0.0% to
20.0%. The incubator is shipped from the factory with a CO2 setpoint of
0.0%. At this setting, all CO2 control and alarms are turned off. To

Calibration
After the unit has stabilized, several different systems can be calibrated. In
Calibration mode, the air temperature, CO2 and RH levels can be
calibrated to reference instruments. To access Calibration mode, press the
MODE key until the CAL indicator lights. Press the right and/or left
arrow until the appropriate parameter appears in the message display. See
Chart 2-1 at the end of this section for more detail.
Calibration frequency is dependent on use, ambient conditions and
accuracy required. A good laboratory practice would require at least an
annual calibration check. On new installations, all parameters should be
checked after the stabilization period.
Prior to calibration, the user should be aware of the following system
functions. While the unit is in Calibration mode, all system control
functions are stopped so the unit remains stable. Readout of the system
being calibrated appears on the message display. If no keys are pressed for
approximately five minutes while in Calibration mode, the system resets to
RUN mode so control functions are reactivated.
Caution Before making any calibration or adjustments to the unit, it is
imperative that all reference instruments be properly calibrated. s
Temperature
Before calibration, allow the cabinet temperature to stabilize. Place the
calibrated instrument in the center of the chamber. The instrument
should be in the airflow, not against the shelf.
Temperature Stabilization Periods
Start-Up - Allow 12 hours for the temperature in the cabinet to stabilize
before proceeding.
Already Operating - Allow at least 2 hours after the display reaches
setpoint for temperature to stabilize before proceeding.

Thermal Conductivity
CO2 System
Models 3540 and 3541 have a thermal conductivity (T/C) CO2 sensor.
Thermal conductivity of the incubator atmosphere is not only effected by
the quantity of CO2 present but also by the air temperature and water
vapor present in the incubator atmosphere. In monitoring the effects of
CO2, air temperature and absolute humidity must be held constant so any
change in thermal conductivity is caused by a change in CO2
concentration.
Changing temperature or changing from elevated humidity to room
ambient humidity levels will necessitate a re-calibration of the CO2
control.
Some T/C CO2 sensors go through an aging period, especially on new
installations. Calibration should be checked on a weekly basis, and
adjusted as necessary. When stabilization occurs, checks can become less
frequent.
T/C CO2 Sensor Stabilization Periods
Start -Up - The CO2 sensor has been calibrated at the factory for 37°C
and elevated humidity. Allow the temperature, humidity, and CO2 levels
in the chamber to stabilize at least 12 hours before checking the CO2
concentration with an independent instrument.
Presently Operating - Make sure the chamber doors are closed. Allow at
least 2 hours after the temperature and CO2 displays reach their setpoints
for chamber atmosphere stabilization.

Infrared CO2 System
Models 3542 and 3543 have an infrared (IR) CO2 sensor. Infrared CO2
sensors are not effected by chamber atmosphere temperature or humidity.
However, the light detector in the sensor is effected by wide temperature
changes. Therefore, changing temperature setpoints could necessitate a
recalibration of the CO2. Chamber temperature should be allowed to
stabilize before checking CO2 concentrations with an independent
instrument, especially on start-up.
IR CO2 Sensor Stabilization Times
Start-Up- Allow the temperature and the CO2 of the cabinet to stabilize at
least 12 hours before proceeding.
Presently Operating - Allow CO2 to stabilize at least 2 hours at setpoint
before proceeding.

In addition to other safety features designed into Series 8000DH
incubators, a thermostat is provided to monitor the cabinet’s temperature.
In the unlikely event of a temperature control failure, the thermostat will
turn off all heaters at a cabinet temperature of 160°C, ±5%. This is
intended to be a safety feature to protect the incubator, and is not
intended to protect the cell cultures or the equipment inside the chamber
should a temperature control failure occur. Should such a failure occur,
contact the Technical Services Department or your local distributor.
The microprocessor in Series 8000DH incubators continually scans all
available sensors to ensure that they are operating properly. Should an error
be detected, the incubator sounds an alarm and shows the appropriate
message. Contact the Technical Services Department or your local
distributor.

PREVENTIVE MAINTENANCE
Incubators
Your equipment has been thoroughly tested and calibrated before shipment. Regular preventive maintenance is important to keep your unit
functioning properly. The operator should perform routine cleaning and maintenance on a regular basis. For maximum performance and
efficiency, it is recommended the unit be checked and calibrated periodically by a qualified service technician.
The following is a condensed list of preventive maintenance requirements. See the specified section of the operating manual for further
details.
Thermo Fisher Scientific has qualified service technicians, using NIST traceable instruments, available in many areas. For more information
on Preventive Maintenance or Extended Warranties, please contact Technical Services.
Cleaning and calibration adjustment intervals are dependent upon use, environmental conditions and accuracy required.
Tips for all incubators:
Do NOT use bleach or any disinfectant that has high chlorJOFDPOUFOU
Use sterile, distilled or demineralized water.
Avoid spraying cleaner on the CO2 sensor.
Do not use powdered gloves for tissue cultures.

Section 5
Routine Maintenance
Caution Before using any cleaning or decontamination method except
those recommended by the manufacturer, users must check with the
manufacturer that the proposed method will not damage the equipment. s
Warning It is the responsibility of the user to immediately clean up after
all accidental spills of hazardous materials. Be certain to follow local EHS
policies with regards to personal protective equipment, cleaning, and
disposal. s
Use an appropriate disinfectant, such as quaternary ammonium. All articles
and surfaces must be thoroughly cleaned, rinsed and rough-dried. s
Warning Alcohol, even a 70% solution, is volatile and flammable Use it
only in a well ventilated area that is free from open flame. If any
component is cleaned with alcohol, do not expose the component to open
flame or other possible hazard. Allow the alcohol to fully dry before
turning power on. s
Warning Do not spray the T/C sensor with flammable solutions. The
internal temperature of the CO2 sensor is approximately 150°C when the
unit is in operation. Allow sufficient time for the sensor to cool before
cleaning. s
Caution Do not use strong alkaline or caustic agents. Stainless steel is
corrosion resistant, not corrosion proof. Do not use solutions of sodium
hypochlorite (bleach), as they may also cause pitting and rusting. s
Note If condensation is visible on the ceiling of the chamber, yet the
message center does not display ADD WATER, then the liquid level
switch could be faulty. Call Technical Services.
Warning If the unit has been in service, disconnect the power cord from
both the unit and the power source, turn off all gas regulators, and allow
the unit to cool before disinfecting. s

Routine Maintenance
Clean Glass Doors
The chamber glass door and the optional independent inner glass doors
may be cleaned using the same disinfectant as used on the incubator
interior. It is imperative that they be rinsed with sterile distilled water to
remove the disinfectant residue. The doors should then be dried with a
soft cloth.
Some precautions in the cleaning and care of the incubator glass doors:
Moisture leaches alkaline materials (sodium, Na) from the surface of the
glass. Evaporation of the moisture concentrates the alkaline and may
produce a white staining or clouding of the glass surface. Cleaning
chemicals with a PH above 9 and heat (autoclaving) accelerate the
corrosion process. Therefore, it is very important to rinse and dry the glass
doors after cleaning. Autoclaving the glass doors should be avoided.
There is no simple method for repairing corroded glass. In most cases, the
glass must be replaced.
Clean Humidity Pan

displayed. The REPLACE HEPA reminder can be set to alarm after a
specified time from 1 to 12 months. The reminder default is the factory
recommended setting of 6 months. For details, see Section 3.
To access the only replaceable fuse in the incubator:
1. Turn off the incubator’s power switch and unplug the power cord.
2. Remove the two screws from the top of the control panel. Grasp the
control panel on each side and pull straight outward.

Sterilization Cycle
Information You Need to Know Before Starting a Cycle
•
The Sterilization Cycle requires approximately 12 hours heat-up (2-4 hours), sterilize (2 hours), and cool down (6-8 hours).
Additional time is needed to verify the calibration of temperature and CO2 after the cycle is
complete.
•
During the Sterilization Cycle, the incubator updates the temperature to the analog output
board and the 1535, however CO2 will be fixed at setpoint and RH will be fixed at RH
Low Limit plus 1%.
•
A HEPA filter replacement kit (see the spare parts list) should be on hand prior to
initiating the Sterilization Cycle.
Information About the Cycle
•
Pre-cleaning may be required. In order to avoid odors, stains on the interior, baked-on
material, etc., wipe off all visible signs of spills.
•
Odor may occur during the Sterilization Cycle and is considered normal.
•
The Steri Cycle is not intended to sterilize other items; instruments, etc., from the lab.
•
During the cycle, the unit chamber becomes hot enough to melt samples, instruments,
dishes, etc., left inside the unit. The items listed below also need to be removed.
1) HEPA filter
2) Air sample filter
3) Access port filter assembly
4) Water in the humidity pan
5) Temp/RH recorder probe, if applicable
6) IR sensor, if applicable
•

calibrations be verified periodically during the first week of returning
the unit to service.
Caution The high temperature sterilization cycle may cause the T/C CO2
sensor output to change significantly. (This is normal and does not
indicate damage to the sensor.) Therefore it is essential that the CO2
calibration is verified before returning the unit to service. s
If an independent instrument is not available to verify calibration, the
following procedure may be performed. After the Sterilization Cycle and
before CO2 is allowed to enter the cabinet;
1) Fill and install the humidity pan.
2) Allow to stabilize at the desired operating temperature for at least 12
hours.

Humidity Readout
Series 8000DH incubators are equipped with a humidity sensor to
monitor the relative humidity inside the chamber. The sensor is located on
the chamber ceiling and provides a signal that is displayed in 1%
increments on the control panel. The humidity readout can display
continuously, or toggle with the temperature readout. In addition, a low
alarm limit can be set on the humidity readout to detect when the
humidity pan runs dry. Refer to Section 3, Configuration.
The sensor is capable of measuring relative humidity from 10% to 100%
with an accuracy of ±5% above 90%. See Section 2, Calibration, for
details on calibrating the humidity readout.
Factors which may affect humidity levels in the chamber are: the water
level in the humidity pan, frequency of door openings, and the fact that
the humidity pan is located on the bottom of the chamber versus on a
shelf.
Caution Incubators equipped with a T/C (thermal conductivity) CO2
sensor rely on a constant level of relative humidity to accurately measure
and control the CO2 concentration in the incubator. s

__________________________________________________________
1 Installation category (overvoltage category) defines the level of transient overvoltage
which the instrument is designed to withstand safely. It depends on the nature of the
electricity supply and its overvoltage protection means. For example, in CAT II which is
the category used for instruments in installations supplied from a supply comparable to
public mains such as hospital and research laboratories and most industrial laboratories,
the expected transient overvoltage is 2500V for a 230V supply and 1500V for a 120V
supply.
2 Pollution Degree describes the amount of conductive pollution present in the
operating environment. Pollution degree 2 assumes that normally only non-conductive
pollution such as dust occurs with the exception of occasional conductivity caused by
condensation.
