5. My system has boot-up problems, or does not turn on...
Make sure the ATX wire lead is connected to “NO” (Normally Open) on the rear
of the unit. (See: “Reservoir and Pump Connections” for details.)
If this does not solve the issue, it is unrelated to the Koolance unit. In a computer,
a problem with the RAM, motherboard, power supply, video card, processor,
or monitor can cause the system to appear not to boot-up properly.
6. My system appears to be leaking fluid...
It is possible a connection was not properly sealed (however unlikely). If you
can see liquid somewhere on the tubing, or at the bottom of the chassis,
computer components may need to be removed for a system test (see Testing
& Filling
).
If liquid should get onto another computer component, shut down the system,
and remove the component. In many cases, the hardware will be fine after
allowing it to dry. However, the system should not be operated until you have
discovered where the leak is coming from and can repair the problem. Should
the leak be situated somewhere where it can not be easily repaired, please
contact our Technical Department for further assistance.
7. My computer’s BIOS gives me errors that there is no cooling fan attached...
Some motherboards will not boot, or may generate an error or alarm if no
cooling fan is attached to the CPU or motherboard chipset power connectors.
There is typically an option to disable this warning in BIOS, but you may
need to boot with a fan attached initially to disable this setting. If the system
is not booting due to this problem, clear the CMOS and try configuring BIOS
again.
8. The Display Panel shows “OPEN” for a temperature sensor...
This indicates a temperature sensor was not found for the specified channel.
If there is no sensor connected to that channel, this is its normal status.
9. The front display is locked up or not responding.
This can happen if the unit is powered off within 5 seconds of being powered
on. Reset the display to manufacturer defaults by holding ▼ + ▲ for 5 seconds.
Three beeps will be heard to indicate the unit was reset. After a reset, all con-
figuration settings (temperature, alarm, fans, etc.) must be updated again.
10. The flow meter reads “0”.
Make sure the Koolance flow meter you have purchased is directly connected
to the back of the unit (See Connecting the Unit). Also be sure the correct flow
meter model and tubing ID are selected via the front display (See Display
Panel
).
