General Deployment Rules
The HRE-819 is an air-tight enclosure. This environment traps the heat generated by the installed plugs causing
a significant heat rise within. The maximum number of doublers that can be reliably housed in the HRE-819 is a
function of the plug types.
The 239T1 repeater may occupy any number of slots without impacting the deployment rules.
Even when you obey the deployment rules, the metal surfaces of the installed units can feel hot to the touch when
removed from an HRE-819 that is operating in elevated ambient temperatures. This is a normal condition. The
plugs are designed to withstand these elevated temperatures.
