McIntosh MCC302 manual Installation, Amplifier Ventilation, Removing the Glass Panel

Installation

Installation

It is recommended that a professional who is skilled in all aspects of installation and operation install the MCC302 and any associated mobile audio equipment.

Amplifier Ventilation

Always provide adequate ventilation for the MCC302. The amplifier requires an adequate airflow into the cooling fans, which are located on the left side of the amplifier. The warm air exits the amplifier through vents on the heatsinks. See figure 1. Be sure to provide at least 1-1/2 inches clear- ance in front of the cooling fans and 1 inch clearance at the sides of the heatsinks.

The cooling fans are controlled by temperature sensors, attached to the interior of the tunnel. The fans are normally off. If the program material contains sustained loud pas- sages demanding high power, the fans will turn-on to in- crease cooling. If cooling is still not sufficient, additional heating will shut down the amplifier’s internal power sup- ply completely and the Power Guard LEDs will light. The fans will continue to run and once normal temperatures are restored, operation will resume.

The amplifier can be mounted vertically or horizontally and may be located under a seat if adequate clearance is available. The preferred installation method is to mount the amplifier directly to the vehicle frame using the hardware supplied with the amplifier.

It is not recommended that the amplifier be mounted under the hood or in a location where it will be directly ex- posed to the elements. The openings in the fan housings and heat tunnel vents can allow internal components to be damaged by exposure to water, chemicals or any form of road dust or debris.

Removing the Glass Panel

To access the MCC302 Controls, remove the glass panel by removing the four hex bolts with the supplied 3/32” hex key. See figure 2. Attach the supplied suction cup to the top center of the glass panel and carefully raise it high enough to put your hand under. Temporarily place the removed glass panel in a safe place, remove the suction cup and save it for future use.

Removing the End Caps

To access the MCC302 Connecting Terminal Blocks, re- move the Glass Panel first (the above step) and then re- move the Phillips Screws holding the End Caps on both sides of the amplifier and lift the end caps off. See figure 3.
