Central Energy Management DrainBack Piping
The following piping diagram shows how to install the DrainBack components correctly. The DrainBack system is simple and very efficient, but each installation must allow for a 1/4 inch slope per foot. CEM's controller will shut the system down when outside temperatures drop below freezing. The slopping allows the distilled water to drainback when the controller goes into freeze protection mode.
In the event that a given installation will not allow for gravity drainback you will be required to use a Glycol System. To see our Glycol System click here
