Diagnostics
The CoolWorks IceProbe has a straightforward diagnostic system that makes it easy to determine the cause of performance
problems. By observing the status of the LED on the electrical cover and determining if the fan motor is operating, the most
common failures can be identified and resolved.
The easiest way to verify whether or not the IceProbe is functioning properly is to simply remove it from the reservoir and run it
with the probe in the open air. If working properly, the probe should be noticeably cold to the touch within several minutes and
should get cold enough to form dew or even frost within 30 minutes. If the probe does not get cold, please refer to this diagnostic
chart:

Please contact a qualified electrician if the cause of the problem is related to your electrical outlet. Replacement power supplies
can be purchased from CoolWorks Resellers or CoolWorks Customer Service and can be easily installed. Fan motor, safety
thermal fuse, and thermoelectric cooling module repairs must be performed by the CoolWorks Repair Center.
Power Specifications
The IceProbe is a “low voltage” device that is designed to draw about 5 amps at 12 volts DC (60 watts). The power converter
provided with your chiller will convert the 120 volt AC electricity from your wall outlet to the correct 12 volt DC output required
by the chiller.
NEVER ATTEMPT TO POWER THE ICEPROBE BY PLUGGING IT DIRECTLY INTO A 120 VAC ELETRICAL OUTLET.
Place the power converter in a clean, dry place, where air can circulate around it freely.
Connect the 4-prong plug into the chiller and the 2-prong plug into the wall outlet.
DO NOT SUBMERGE THE ENTIRE UNIT OR ANY ELECTRICAL WIRES IN WATER. ONLY THE PROBE PORTION
OF THE DEVICE SHOULD CONTACT WATER.
