Plug in the power cord to a properly grounded main circuit. The LCD should display
the actual temperature. The temperature of each channel should fall until it reaches
5
C.
If there are no alarms (an alarm condition consists of water slip detection after the
cooler, thermocouple failure, or actual temperature > 10°C), then the LED(s) should
turn to an amber color. This indicates that the alarms are cleared and the user can
press the reset button to begin operation. Once the reset button is pressed, the
LED(s) should turn green indicating that there are no alarms and sample flow can
begin. If the sample pump is wired through the relay board alarm contacts and all
alarms are cleared, the sample pump will start. The sample pump will stop if any
alarms are detected.
Note: Current alarm conditions are displayed on the second line of the LCD.
eCOOL™ 5000 Thermo-Electric Coolers are virtually maintenance free. However, in
the event of electrical problems, refer to the Troubleshooting section in this manual.
