We hope your Koolance system will provide you with years of reliable cooling
performance. To help avoid unnecessary RMA issues, we have prepared this list
of possible operational problems, and their most common solutions.
1. After filling the reservoir with coolant and turning on the system, there are no
visible signs of liquid movement...
Check the flow meter value (see “DISPLAY SET”). If there is no detected flow
immediately after filling the reservoir, or the flow rate is very low or periodic,
this usually indicates the pump has not finished priming. Open the fill port on
top of the reservoir and temporarily set the pump speed to 10 (see “PUMP
SET”) to help push out the air.
If possible while the pump is running, gently tilt your cold plates or other
components connected to the system in various directions to assist with
bleeding air from the cooling loop. If it becomes necessary to significantly tilt
the unit to assist with priming, close the fill port and power-off the unit before
doing so.
2. The temperature alarm sounds and I’m not sure why...
The offending temperature sensor and value will flash in the front display
whenever an alarm sounds. Check that your currently selected temperature
sensor and alarm are configured as desired (see “TEMP SET” and “ALARM
SET”). If you are certain the cooling system is working properly otherwise, try
resetting all system settings by holding
▼ + ▲ for 3 seconds.
3. My system appears to be leaking fluid or water...
Check that all fittings are properly installed and tightened. This product uses
both parallel and tapered threaded fittings. Be sure only to use plumber’s tape
on the tapered fittings (see “Combining Modules” and “Tube Fittings”).
4. The front display is locked up or not responding.
Reset all system settings by holding
▼ + ▲ for 3 seconds. After a reset, all con
-
figuration settings (temperature, alarm, fans, etc.) must be updated again.

Software Feature
This unit supports Koolance’s “System Monitor” application for adjusting and view-
ing cooling values and logging data to a computer file. Visit www.koolance.com/
software to download the latest version of the program. Consult the application’s
readme.txt for further details.
Draining
There is a drain on the rear of the unit for emptying
or replacing the coolant. Before opening the drain
plug, remove the top coolant fill port to allow air into
the reservoir.
