1.4 Safety
1.4.1 Warnings
Operating the equipment in a manner not specified within this manual or under
conditions outside of the equipment specifications, may result in the protection offered
by the equipment being impaired.
Use in well ventilated areas. Risk of asphyxiation from carbon dioxide released from
the equipment. Additional ventilation may be required. Consider carbon dioxide alarms
in confined spaces. Refer to the Gas supply topic for gas release rates.
Never connect to flammable or oxidising gas mixtures.
Do not connect to a gas supply with a pressure exceeding 1.65 bar.
Take care when handling samples. Samples may present other biological hazards.
Refer to the person responsible for the equipment.

Introduction
Do not attempt to charge the battery externally. The BT37-02 contains a sealed lead
acid battery. Over-charging can result in the release of dangerous gases. Refer to the
Internal battery topic for details.
Equipment must be earthed. Class 1.
Supply power via a residual current circuit breaker (RCCB) operating at a differential of
30 mA.
To avoid risk of fire, fuses must always be replaced with the same type and rating.
oFuses should only be replaced by suitably trained service personnel.
oFuses should only be replaced after the cause of the original failure has been
determined and corrected as appropriate.
1.4.2 Precautions
Ensure the equipment and mains cords are regularly checked by a competent person,
using a Portable Appliance Tester or similar equipment, to ensure adequate earth
bonding.
Ensure the earth continuity of the mains installation is regularly inspected by a
competent person.
Check the voltage requirements of the equipment, shown on the rating label, match
the local mains supply.
The mains lead to the power supply is the main disconnect device. If power needs to
be disconnected immediately, disconnect the mains lead from the power supply or
switch off at the mains power outlet.
Ensure the equipment is positioned so that the mains lead can be easily
disconnected.
Connected devices must comply with EN60950 or its equivalent.
To ensure you can respond to alarm conditions when the laboratory is unattended, the
equipment should be connected to an independent, external alarm system.
The alarm output must not be used in safety-critical applications.
oAny circuit connected to the alarm output must meet the requirements for an
accessible part as defined in EN 61010-1 or its equivalent.
Do not connect to Ethernet local area networks (LAN) external to the building.
User servicing is limited to cleaning and calibration.
Ensure cables do not cause a trip hazard.
Take care when lifting. Uneven load: 17 kg.
Keep the humidifier lid closed during normal operation.
Operating parameters should only be modified by qualified service personnel or under
their guidance. Entering incorrect values may impair the performance of the product.
The internal battery can only support the incubator for up to 2 hours if mains power
fails. This time is dependent on the battery condition and operating conditions.

Introduction
1.4.3 Electromagnetic compatibility (EMC)
The equipment is intended for use in a basic electromagnetic environment, characterised
by being supplied directly at low voltage from the public mains network.
All connections via the External alarm connection must use fully screened cable
no longer than 2 m.
Take care to avoid placing the BT37-02 in environments influenced by sources of
electromagnetic interference, such as large transformers for example.
1.5 About the equipment
1.5.1 Theory of operation
The basic principle of operation is illustrated in the diagram below.
Samples are placed in dishes in the left and right chambers which are heated to
maintain a constant temperature. Pre-mixed gas is supplied from a pressurised cylinder,
bubbled through water contained in the humidifier bottle, and then passed to the left and
right chambers. This results in the samples being maintained at a controlled temperature
and within a controlled atmosphere.
If the lids are opened and then shut again, gas is provided at an increased flow rate to
reduce the time taken to restore the chambers back to the required gas concentration.
The BT37-02 can be in one of three modes: Standby, Run and Bottle change.

5. Liquid level indicator.
The lids are fitted with rotary catches.
1. To open a lid, rotate the knob anticlockwise and lift the lid.
2. To close a lid, ensure the knob is rotated anticlockwise so it can engage with the pin
on the main body.
3. Gently lower the lid, and when it is fully closed, rotate the knob clockwise until it is
felt to latch.
The BT37-02 will not regard a lid as being shut until it is both closed and the knob
rotated clockwise into its locked position.

2.1 Connecting the gas supply
Warning
The supply pressure must not exceed 1.65 bar.
Never connect to flammable or oxidising gas mixtures.
1. Consult your media supplier for the appropriate gas concentrations. The
concentration may need to be adjusted for local air pressure.
2. Only use medical-grade premixed gas, or medical-grade gases supplied via a gas
mixer.
3. Gas should be supplied at or around the normal lab temperature where the incubator
is being operated.
4. Any tubing used to connect the gas supply should be made of a material that is
impermeable to the premixed gas supply.
5. Clean tube fittings and blow through pipes with medical grade gas to clear any
foreign bodies before assembly.
6. Gas should be provided via a high purity gas regulator. The regulator will require a
SWAGELOK® SS-400-1-4RT fitting to match the hose supplied with the BT37-02.
7. It is recommended that a volatile organic compound (VOC) filter is fitted in the line.
8. Any pipework must be designed to supply at least 360 mL/min per incubator.
9. When tightening the hose fittings, assemble finger tight. Then using a 14.29 mm
(9/16 ") spanner, tighten a further 60 degrees. Do not over-tighten.
10. Connect the hose to the gas supply.
11. Connect the hose to the gas inlet of the incubator.
12. If daisy-chaining incubators:
a. Remove the blanking plug from the gas outlet of the first incubator.
b. Connect a hose from the gas outlet of the first incubator to the gas inlet of the
second.
c. A maximum of 10 incubators can be connected in series.
13. Use soapy water over the joints to check for leaks. If any bubbles are seen, gently
tighten the joint. If bubbles continue, switch off the gas supply, disconnect the hose
and check the fitting for any debris before reconnecting.
2.2 External data collection
The Ethernet connection on the rear of the BT37-02 can be used to collect data via the
local area network. Contact your distributor for details.

20
Installation
2.3 Connecting the external alarm
Caution
To ensure you can respond to alarm conditions when the laboratory is unattended,
the equipment should be connected to an independent, external alarm system.
If you are using an external alarm, you should now connect the external alarm connector
to the alarm system. Details of the connector are given in the External alarm
connection section.
Details of how to connect the external alarm output to your alarm system will depend
upon the characteristics of your external alarm system.
2.4 Connecting to the mains supply
Caution
Check the voltage requirements of the equipment, shown on the rating label, match
the local mains supply.
The plug-in power supply is the main disconnect device. In the event of a fault
occurring that requires the power to be disconnected immediately, switch off the
mains wall power outlet or disconnect the power supply from the outlet.
Ensure the equipment is positioned so that the power supply can be easily
disconnected.
Only use the power supply provided with the equipment.
1. Connect the cable to the mains inlet at the rear of the BT37-02; see the Rear view
section.
2. Connect the power supply to a suitable mains power outlet.
3. The BT37-02 will normally start in standby mode.
