Coolant Interface 

Aspen recommends using Koolance 702 as the working fluid for this system. The use of water without 
additives may result in corrosion and/or biological growth in an untreated system. The coolant and 
customer coolant loop should be clean and free of debris. The RMC is equipped with an internal coolant 
filter; however, this filter is intended to protect the pump from debris in the coolant loop. The presence 
of foreign materials into the RMC, could damage components and reduce system performance. Aspen 
recommends that the customer use an external filter prior to the return line to prevent any foreign 
material from returning to the RMC. 

 

 

Figure 2 - RMC Front Panel 

Coolant Connections 

The coolant connections for the RMC are female LC Series CPC (Colder Products) quick disconnect 
fittings (see Figure 2), with shutoff valves. Male mating connectors (with shutoff valves) must be 
attached to both fittings at startup.  

Filling 

The RMC contains a 1 L reservoir. The reservoir is filled by removing the red fill cap at the front of the 
system (see Figure 2). The system must be about 50% full to operate. Overfilling the systems is not 
recommended to prevent possible spillage. 

Aspen recommends an external coolant filter on the return line to prevent any damage to 

internal components or degradation of the RMC’s cooling capacity and efficiency.
