ALX systems are composed of two modules physically connected together: the
front “RPM” and rear “HXM”. Diagrams below are general representations, as
individual module specications and sizes can vary.

Positioning the System
Combining Modules
If you have purchased both RPM and HXM modules, they are combined together
using hardware included with those products.
This product must be operated in an upright orientation (shown below). Alternative
orientations can prevent the coolant pump from operating properly.
Install the shorter ttings included with the
RPM module onto its rear inlet and outlet.
These should be nger-tightened. (This
is a parallel thread, do not use plumber’s
tape.)
Install the longer ttings included with
the HXM module onto its *front* inlet and
outlet. These should be nger-tightened.
(This is a parallel thread, do not use
plumber’s tape.)

User Manual
Fasten the included mounting
bracket to the rear of the RPM
module using four bracket
screws.
The bracket must match the
orientation shown to the right.
Push the RPM and HXM modules together. Their ttings will mate and seal.
Finish combining modules by securing
the bracket with its remaining four
screws.
Two screws are installed into
corresponding holes on each side of
the HXM module.

There are several available wire terminals near
the reservoir window of the RPM module:
1. Two K-Type Thermocouples (not included)
2. Relay Output NO/NC (normally open or closed)
3. USB for Data Logging (Type B Plug)
4. HXM Module, Fan & Flow Meter ribbon cable
5. Connect power leads to the red positive “+” and
black negative “-” power terminals, as labeled on
the side of the unit.
Connect the included ribbon cable
between RPM and HXM “HX Module”
plugs. For the data logging feature,
attach the included USB cable.
There is a cable guide beneath the
reservoir to hide some of the wiring.
The ALX cooling system requires a 12VDC power supply (not included). Amperage
for RPM and HXM modules are printed separately on their labels. These can be
added together for the total power requirement and range between 2-8A.
CAUTION: Supply only the proper input voltage and polarity to the
cooling system, as labeled below the terminals on the unit. Improper
power can damage the unit and is not covered under the warranty.

For a cleaner appearance, the power and
USB cables can be routed beneath the
HXM module towards the back.
Zip ties are included to secure them to the
radiator grill (use needle-nose pliers).

User Manual
Cut tubing into two segments. You
will need to connect each to the rear
ttings.
Each tubing connection will use a threaded compression
ring or tube clamp to keep it secure. Be sure to thread
the compression ring or tube clamp onto the tubing
before attaching it.
Squeeze the tube while pushing it rmly over
the tting. Tubing should completely cover the
tting or barb. This step can be eased by rst
dipping the end of the tubing in water.
Tighten the connection by sliding the compression
nut down over the tting and screwing securely.
For barbed ttings, use pliers to move the clamp
into the proper position before releasing.
Tube ttings are purchased separately.
Unlike the ttings used to combine RPM and
HXM modules, threading for the tube ttings is
tapered 1/4-inch NPT. Plumber’s tape (PTFE) is required to
seal them properly.
Tube Fittings
After wrapping with tape, the inlet and
outlet fittings should be inserted by
hand, then nished with a wrench for
the last 1-2 rotations.

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 lling 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 ll port cap and add more liquid as needed.
Slowly ll 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 ll port on the reservoir. Do not overtighten the ll
port.
Once all devices (cold plates, ttings,
etc.) have been connected with tubing,
the system can be lled with coolant.
The ll port is located above the reservoir. Remove
the large slot-headed screw with a screwdriver or
large coin.
Coolant Filling and Power-On
WARNING:Most coolants are electrically conductive. Use caution
when lling the system, and keep all liquids away from electronics
and power cables. Keep the primary AC supply unplugged whenever
lling or draining coolant.
!
Coolant will be lled to about 1/2-inch (13mm) from the top of the reservoir. Never
completely ll or “top-o󰀨” the reservoir. An air gap must always remain to ac-
commodate thermal expansion of the liquid.
