HOTLINE
®
3 Blood and Fluid Warmer | Operator’s Manual
Check Disposables Test
An interlock switch/sensor, located in the socket on the right side of the
HOTLINE
3 Warmer, senses a properly installed HOTLINE
3 Fluid
Warming Set. When the switch does not sense a HOTLINE
3 Fluid
Warming Set, the Check Disposables alarm activates.
1
Slowly remove the
HOTLINE
3
Fluid Warming Set (
a
) from the
HOTLINE
3
Warmer socket.
2
Observe the following actions:
• The green Operating LED turns off.
• The red Check Disposables LED (
b
) illuminates.
• The audible alarm sounds and repeats approximately every two
seconds.
Note: In any alarm condition, the pump should not be running. A
small amount of solution dripping from the disconnection is normal
and should stop in a few seconds.
Temperature Verification of the Recirculating Solution
Use the Level 1
TEMP CHECK Thermometer (HLTA-390) to verify the
displayed recirculating solution temperature. Other methods of
temperature verification may be inaccurate.
TEMP CHECK provides an accurate reading of the highest temperature of
the recirculating solution. Because the temperature of the reservoir is
typically 0.5°C to 2.0°C lower than the temperature from the heater, and
the temperature of the recirculating solution begins to drop due to the
effect of ambient temperature on the HOTLINE
3 Fluid Warming Set,
the highest temperature of the solution is just after it leaves the heater.
During the temperature verification test, the TEMP CHECK is positioned
on the right side of the HOTLINE
3 Warmer attached to the socket and
senses the solution just after it leaves the heater and before it enters the
HOTLINE
3 Fluid Warming Set.
Refer to the TEMP CHECK HLTA-390 Thermometer Operator's Manual
for complete Temperature Verification and Calibration Instructions.
