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.

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.
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.
