Check Disposables Test
An interlock switch/sensor, located in the socket on the right side of the
HOTLINE
Warmer, senses a properly installed HOTLINE
Fluid
Warming Set. When the switch does not sense a HOTLINE
Fluid
Warming Set, the Check Disposables alarm activates.
1
Slowly remove the HOTLINE
Fluid Warming Set (
a
) from the
HOTLINE
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-40) 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
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
Warmer attached to the socket and senses the
solution just after it leaves the heater and before it enters the HOTLINE
Fluid Warming Set.
Refer to the TEMP CHECK HLTA-40 Thermometer Operator's Manual
for complete Temperature Verification and Calibration Instructions.
