Bair Hugger Model 750 Temperature Management Unit Operator's Manual

Viewing the Temperature Mode Timer

The temperature mode timer records the amount of time the temperature manage-
ment unit has been operating in the selected temperature mode. The timer resets
itself every time you select a different temperature mode.
To view the temperature mode timer, press the button for the current temperature
mode, and hold it for 2 seconds. The alphanumeric display will show the tempera-
ture mode time, then go back to showing the temperature mode setting.

What to Do in Case of an Over-Temperature Condition

If an over-temperature condition occurs, the red Over-temp indicator light flashes
and an alarm sounds. The unit automatically turns the heater, blower, and operating
mode indicator lights OFF. The control panel will not respond to commands, but
pressing any button will silence the alarm.

If an over-temperature condition occurs:

1. Discontinue all temperature management therapy. If you are using the 241
blood/fluid warming system, immediately stop fluid flow and discard the
blood/fluid warming set.
2. Unplug the temperature management unit.
3. Contact a qualified service technician.

What to Do in Case of a Fault Condition

The Model 750 temperature management unit's software recognizes several non-
hazardous conditions and reports those conditions as faults. When a system fault
occurs, the software stores the fault code in memory, the amber Fault indicator light
flashes, and an alarm sounds. The control panel will not respond to commands, but
pressing any button will silence the alarm.
If a fault condition occurs:
1. Unplug the temperature management unit and wait for 5 minutes.
2. Reconnect the temperature management unit to a grounded power source.
The unit will perform the normal power-on-reset sequence and then enter the
Standby mode.
3. Reselect the temperature setting.
4. If the unit does not return to normal operation, contact a qualified service
technician.
