C.
Primary High Temperature Safety Alarm
1.
If the circulating water reaches 43.5°C
±
0.6°C (110°F
±
1.08°F), the primary
high temperature safety will activate to turn off the pump and turn off heater.
In addition, the HI TEMP LED flashes and the audible alarm sounds.
2.
If the primary high temperature alarm occurs, the unit should be powered off
and the power cord removed from the outlet. The unit should be immediately
removed from service and sent to Biomedical Engineering for repair.
D.
Secondary High Temperature Safety Alarm
1.
If the circulating water reaches 44.5°C ± 0.6°C (112°F ± 1.08°F) the secondary
high temperature safety will activate to turn off the pump and the heater. In
addition, the HI TEMP LED illuminates and the audible alarm sounds.
2.
If the secondary high temperature alarm occurs, the unit should be powered off
and the power cord removed from the outlet. The unit should be immediately
removed from service and sent to Biomedical Engineering for repair.
E.
Independent Mechanical High Temperature Safety Alarm
1.
If the circulating water reaches 46.0°C ± 0.6°C (115°F ± 1.08°F) the
independent mechanical high temperature safety will activate to shut off the
power to the pump and heater. In addition, the HI TEMP LED and Power Fail
LED illuminate, and the audible alarm sounds.
2.
If the independent mechanical high temperature alarm occurs, the unit should
be powered off and the power cord removed from the outlet. The unit should
be immediately removed from service and sent to Biomedical Engineering for
repair.
F.
1°C (2°F) Over Set point Alarm
1.
If the set point temperature has been set at least 1°C (2°F) lower than the
actual circulating water temperature, the 1°C (2°F) Over Set point
Temperature Alarm will activate to turn off the heater, the HI TEMP LED
flashes, the “WATER” display flashes the actual water temperature and the
audible alarm sounds.
2.
The heater will remain off, the HI TEMP LED will continue to flash and the
“WATER” display will continue to flash until the actual circulating water
temperature is within 1°C (2°F) of the set point temperature. No additional
action is required.
G.
Defective Water Temperature Sensor
1.
If the “WATER” display reads “ERR” or “PF” the unit may have a defective
water temperature sensor and an alarm will sound.
2.
If the “WATER” display reads “ERR” or “PF” the unit should be powered off and
the power cord removed from the outlet. The unit should be immediately
removed from service and sent to Biomedical Engineering for repair.
