Power on the cooling unit, and increase the pump speed to move coolant if 

needed. When most of the air has been pushed out of the tubing, the liquid 

noise will decrease. This process can take several minutes, depending 

on the filling technique and components attached to the cooling system.

During this process, liquid components (or the cooling system itself) may need to 

be tilted gently to assist with air evacuation. The reservoir level will decrease during 

this procedure. Remove the fill port cap and add more liquid as needed.

Slowly  fill  the  system  with  coolant.

 To 

maintain the product warranty, use 

only Koolance approved coolant. 

Many alternative liquids and additives 

can cause permanent damage to the 

cooling unit (through chemical reaction, 

corrosion, biological growth, high thermal 

expansion, viscosity, etc.).

Replace the fill port on the reservoir (hand tightening is recommend

-

ed).

 Do not overtighten the fill port.

Coolant will be filled to about 1/2-inch (13mm) from the top of the reservoir.

 Never 

completely fill or “top-off” the reservoir.

 An air gap must always remain to ac-

commodate thermal expansion of the liquid.

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.

Software Feature

This product supports Koolance’s “System Monitor” application for adjusting and 

logging cooling system values from a computer via the USB port. Visit www.kool-

ance.com/software to download the latest version of the program. Please consult 

the application’s readme.txt for further details.

External Sensors

This unit has an integrated liquid temperature sensor in the 

reservoir. It also provides terminals for connecting up to two 

K-type thermocouples (not included) for external temperature 

monitoring and set point options.
