Page 16: Racking Options
RACKING OPTIONS While we strongly recommend leaving at least a full 1 unit of rack space above and below the HERCHILD, we have equipped it with additional racking holes to provide the option to reposition the unit to allow only 1/2 rack space. Avoid at all costs! Your HERCHILD needs to breathe! Never install anything directly above and below it. - Page 17 HERITAGE AUDIO. C/ Alfonso Gómez, 38, 3C. 28037 Madrid – Spain.
