E. Independent Mechanical High Temperature Safety Alarm
1. If the circulating water reaches 46°C ± 0.6°C the independent
mechanical high temperature safety will activate to shut off the power
to the pump, shut off the power to the heater, the HI TEMP LED and
Power Fail LED illuminate, and the trouble 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 Over Set point Alarm
1. If the set point temperature has been set at least 1°C lower than the
actual circulating water temperature, the 1°C 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 trouble 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 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.
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
