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.
