The HRE-504 is an airtight enclosure. The breather valve on the gel-filled units and the pressure relief valve on 
the air-filled units allow minimum ventilation to the atmosphere. This environment traps the heat generated by the 
installed plugs and, in effect, causes the heat temperature to significantly rise within the enclosure. The number 
of doublers or remote units that can be housed in the HRE-504 is dependent on:

Plug type

Doubler version (the list number of the doubler version will also affect the number of doubler units housed 
in the HRE-504)

Solar exposure

Unit orientation

Table 4

 lists the deployment rules for doubler and remote unit applications. Even if the deployment rules are 

followed, the metal surfaces of the installed units can feel hot to the touch when removed from an HRE-504 that 
is operating in elevated ambient temperatures. This is a normal condition for the plugs operating in these 
circumstances. The plugs were designed to withstand these elevated temperatures.

When less than four slots are used, always try to leave empty slots between adjacent units. This reduces the hot 
spot temperature. Also, always use the last column deployment rules when mixing units from both columns in the 
same enclosure.

To comply with the requirements in TA-NWT-0012101 (maximum ambient temperature of 115°F with full solar 
load), the number of full T1 HDU-439 or HDU-437 doublers must be limited to two without full solar load or three 
with full solar load. The fractional doublers (HDU-219 and HDU-217) and the full T1 microdoublers (HDU-409 
and HDU-407) comply with the TA # when all four slots are occupied with full solar load.

Four T1 repeaters or two DDS ISDN repeaters are thermally equivalent to one HDU-439 doubler. 
Also, one HDU-439 or HDU-437 doubler is thermally equivalent to 1.5 HDU-217, 219, 407, or 409 
doublers. When fractional values result from applying these equivalent relationships, always 
round up to the nearest whole number.
