(polarized) plug with an extension cord, receptacle
or other outlet unless the blades can be fully inserted to prevent blade exposure.
Installation:
9. Locate the equipment for proper ventilation. For example, the equipment should not be placed on a bed,
sofa, rug, or similar surface that may block ventilation
openings; or, placed in a built-in installation, such as a
bookcase or cabinet, that may impede the flow of air
through the ventilation openings.
10. Locate the equipment away from heat sources such as
radiators, heat registers, stoves, or other appliance (including amplifiers) that produce heat.
11. Mount the equipment in a wall or cabinet only as described in this owners manual

walked on or pinched by items placed upon or against
them, paying particular attention to cords at plugs, convenience receptacles, and the point where they exit from
the instrument.
16. Do not defeat the inherent design features of the polarized plug. Non-polarized line cord adapters will defeat
the safety provided by the polarized AC plug. If the
plug should fail to fit, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the grounding-type plug.

Installation
The C15 can be placed upright on a table or shelf, standing
on its four feet. It also can be custom installed in a piece of
furniture or cabinet of your choice. The required panel cutout, ventilation cutout and unit dimensions are shown.
Always provide adequate ventilation for your C15. Cool
operation ensures the longest possible operating life for
any electronic instrument. Do not install the C15 directly
above a heat generating component such as a high powered
amplifier. If all the components are installed in a single
cabinet, a quiet running ventilation fan can be a definite
asset in maintaining all the system components at the
Installation
coolest possible operating temperature.
A custom cabinet installation should provide the following minimum spacing dimensions for cool operation. Allow
at least 1-1/2 inches (3.8cm) above the unit so airflow is
not obstructed. Allow 17-1/2 inches (44.5cm) depth behind
the mounting panel, which includes clearance for connectors. Allow 1-1/8 inches (2.9cm) in front of the mounting
panel for knob clearance. Be sure to cut out a ventilation
hole in the mounting shelf according to the dimensions in
the drawing.
