Care Essentials CWS4000 Cocoon Warming System Service Manual
3. SAFETY PRECAUTIONS
Review the following safety precautions prior to servicing the CWS4000.
3.1. Danger
e Explosive hazard. Do not use in the presence of flammable anaesthetic agents.
e Risk of electric shock. Disconnect mains power before servicing the CWS4000.
3.2. Warning
e Ensure that no direct or indirect contact is made between the patient and the communications
connector located on the rear of the CWS4000.
e The CWS4000 must only be opened or serviced by qualified personnel such as certified
biomedical electronics technicians or certified clinical engineers familiar with repair practices
for servicing medical devices, and in accordance with the Service Manual. Damage to the
CWS4000 or malfunction could otherwise result.
e Ensure the CWS4000 is subjected to the specified routine electrical safety and performance
inspections.
e Inthe event of excess fluid contact with the CWS4000 it is recommended that the unit be
disconnected from the mains power supply and checked by qualified personnel.
e Use only in accordance with Operator Manual instructions.
3.3. Caution
e Operate the CWS4000 only in the specified supply voltage range and environmental
conditions and as detailed in Section 11 below.
ο When using an IV pole, do not mount the CWS4000 higher than 1 metre or it could tip over.
e The 46°C setting is not recommended for patients who are non-responsive or with impaired
circulation.
e It is not recommended that the unit be operated after the filter has exceeded the specified
life period.
3.4. Electromagnetic Interference
The CWS4000 has been designed to comply with IEC 601-1-2:2004 (Medical electrical
equipment — Part 1: General requirements for safety. 2. Collateral standard: electromagnetic
compatibility — Requirements and tests) but this does not guarantee that other equipment in the
vicinity will not be affected by the electromagnetic emissions from the CWS4000. Similarly,
other equipment in the vicinity may affect the operation of the CWS4000.
It is recommended that all equipment used near the CWS4000 comply with the relevant
electromagnetic compatibility requirements for that equipment and to check before use that no
interference is evident or disruptive. Increasing the distance between offending devices, and
keeping interconnecting leads as short as possible will help reduce the effect.
