TROUBLESHOOTING
6.1.
Warming Blanket Will Not Inflate
Make sure the CWS4000 is plugged in to an energized mains power socket-outlet.
Check both ends of the delivery hose for proper connection.
Check the delivery hose and warming blanket inlet for kinks.
Check that there are no obstructions to the air inlet slots.
Check the warming blanket for damage. If air is flowing from the hose, try another warming
blanket. Small rips or tears in the warming blanket may be temporarily repaired with adhesive
tape.
Request qualified service personnel check for a clogged or dirty filter.
Check for fault alarm.
6.2.
Standby Indicator Will Not Light
Extremely high storage temperatures (such as those found motor cars on hot summer days) can
cause the temperature limit thermostats in the CWS4000 to actuate. Should this occur, the
standby indicator (B)
will fail to light when the CWS4000 is connected to mains power. If this
occurs, simply wait for the CWS4000 to cool down and eventually the thermostats will
automatically reset and the
standby indicator (B)
will light.
Request qualified service personnel check for blown mains power fuses.
6.3.
Equipment Repairs
Repairs to the CWS4000 should be performed by qualified personnel such as certified
biomedical electronics technicians or clinical engineers familiar with repair practices for
servicing medical devices, and in accordance with the CWS4000 Service Manual. Damage to
the CWS4000 or malfunction may otherwise result.
