TE-BBR System Preparation & Maintenance 

 

Note:

 

Complete the TE-BBR assembly before beginning procedures in this 

section. 

Fill the Air/Water Heat Exchanger 

Obtain a supply of quality ethylene glycol (automotive antifreeze) and mix it with water in a ratio of 
30 percent ethylene glycol to 70 percent water. After the Exchanger tubing connections are secured 
(see section Tubing Connections), pour the mixture into the reservoir opening on the top of the 
Air/Water Heat Exchanger until it is full (approximately 1-2 liters). Refer to Figure 13. 

 

Figure 13: Air/Water Heat Exchanger Reservoir 

 

Caution:

 

Replace water/anitfreeze mixture annually to ensure reliable 

performance and prevention of corrosion of internal components. Ethylene

 

glycol is a toxic substance. Use proper safety measures when handling. Follow 
appropriate (M)SDS procedures.

 

 

Do not use "environmentally friendly” alternatives to ethylene glycol (such as polyethylene glycol) in 
the heat exchanger. Such products can coagulate under colder conditions and damage the TE-BBR 
circulation system.
